Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional Patent
Application Ser. No. 62/062,425 filed Oct. 10, 2014, which is
incorporated herein by reference in its entirety and for all
purposes.
FIELD OF THE INVENTION
[0002] The present invention is directed to an authenticating
apparatus, system and a method for authentication of an object or
product having a secure glyph thereon, wherein the secure glyph has
an intellectual property protected feature and a machine readable
feature. The invention is also directed to the use of the object or
product having a secure glyph thereon in a machine or device.
BACKGROUND OF THE INVENTION
[0003] Systems and methods have been employed to prevent or reduce
counterfeiting, infringement and the parallel importing of objects
and products carrying a valuable piece of intellectual property,
such as a company name, logo, image, brand, copyright or
trademark.
[0004] Most systems and methods contain one or more protection
features in the form of security or authentication measures
classified into three types of object or product authenticity
protection, each offering a different level of security. These are
referred to in the security industry as a "Level 1" (readable by an
ordinary citizen), Level 2" (machine-readable with immediate
response) and "Level 3" (machine readable with dedicated tools
where the response is not readily obtainable in real time, or other
forensic means) security measures.
[0005] A Level 1 security measure involves the use of features that
can be recognized overtly, e.g. by sight or touch by an end user of
the object or product. Such features include holograms and markings
by optically variable ink. In the case of a hologram, one is
looking for a specially designed holographic pattern and in the
case of an optically variable ink, the marked pattern shows
different colors when viewed at different angles.
[0006] A Level 2 security measure involves the use of covert or
semi-covert features that require interrogation by a simple and
easily obtainable detection device. Examples include printed
sectors in banknotes bearing fluorescent marks made from inks
containing downconverter and upconverter taggants. In this case,
one only needs an ultraviolet or infra-red laser interrogation
source for verification of an object or product having the ink
applied. When light in an appropriate waveband is illuminated onto
the ink containing taggant, due to the taggant, the ink will emit
visible light, which can be observed readily by the naked-eye.
Alternatively, the ink may, due to the taggant, emit radiation of a
wavelength invisible to the naked-eye, but readable and verifiable
by a suitable reader.
[0007] Finally, a Level 3 security measure involves the use
features that are generally known only to the brand or currency
manufacturer of an object or product and can be verified, usually
not in real time, by dedicated interrogation tools that cannot be
readily obtained commercially in the marketplace.
[0008] US 2010/0149531 is directed to a Level 2 authentication
measure and describes an authentication method for an object or
product containing an image, where the image contains or forms part
of a taggant used in a coded readable security feature. The coded
readable feature is subject to an authentication process that
identifies and verifies the object or product. However, because the
taggant represents the only source of the identification and
authentication security feature, and given that the machine
readable security feature of the image is coded, it therefore does
not contain or form part of an intellectual property protected
feature. As a result, a counterfeiter would find it relatively easy
to introduce counterfeit or infringing objects or products
containing or using the coded image into the commercial stream
where such objects and products are marketed and sold. For example,
a counterfeiter could evaluate and ultimately determine how to
identify, source and formulate the taggant, reproduce the coded
security feature of the image and apply it to a copied or
counterfeit object or product, then introduce such object or
product into the commercial stream.
[0009] Alternatively, a counterfeiter could evaluate and ultimately
determine how to decode and reprogram the authenticating reader
used to read the existing coded security feature of the image
containing or forming part of the taggant so that it reads the
counterfeiter's coded image. By adopting either or both of these
approaches, a counterfeiter could successfully circumvent the
authentication process or measures being used by the owner or
marketer of the object or product without having infringed any
intellectual property right of the owner or marketer in the object
or product.
[0010] U.S. Pat. No. 8,403,223 is also directed to a Level 2
security measure and describes an authentication method for
textiles containing two invisible designs having readable features
and used to identify, authenticate and track textiles. However,
again given that the invisible designs themselves are not, nor do
they contain any, intellectual property protected features, the
invisible designs serve as the only security feature for
identifying and authenticating the textiles. As a result, a
counterfeiter would again, find it relatively easy to introduce
counterfeit, copied textiles into the commercial stream without
having infringed any intellectual property right of the owner or
marketer in the textiles.

BRIEF DESCRIPTION OF THE DRAWINGS
[0039] FIG. 1 shows a block diagram of an authentication apparatus
according to an embodiment of the present invention.
[0040] FIG. 2 shows a spectral curve with an analog signal
converted to discrete digital values.
[0041] FIG. 3 shows a typical object or product authentication work
flow according to a particular embodiment of the present
invention.
[0042] FIG. 4 illustrates the spectral range to scan in order to
identify a specific taggant material. In this illustration there
are 2 taggants one scanning from WL1 to WL2 to read taggant 1 and
one from WL3 to WL4 to read taggant 2.
[0043] FIG. 5 illustrates a secure glyph with 4-fold rotational
symmetry and four readers to identify the geometric design, its
position and other graphics of the secure glyph.
[0044] FIG. 6 illustrates a secure glyph with 4-fold rotational
symmetry and four readers in which the secure glyph has been
rotated to a position where the readers cannot detect the geometric
design, position and other graphics of the secure glyph.
[0045] FIG. 7 illustrates a secure glyph with 6-fold rotational
symmetry and three readers in which the geometric design, position
and other graphics of the secure glyph are fully identified by the
readers.

readers, even though the orientation is not the same as that in
FIG. 7.
[0047] FIG. 9 shows a secure glyph having four colored areas and
four color-selective readers. The signal response for each reader
is proportional to the area of the secure glyph of a specified
color, when the glyph is interrogated with four separate
wavelengths of light and read by a reader, camera,
spectrophotometer or the like capable of distinguishing those four
wavelengths of light.
[0048] FIG. 10 shows a secure glyph having four colored areas and
four color-selective readers. The signal response for this secure
glyph, and thus the presence or absence of any rotational symmetry
of this secure glyph (that is to say, does it appear as a single
square of fourfold rotational symmetry or as four conjoined squares
of no rotational symmetry) may be different depending upon which
wavelength(s) of light are used to interrogate the secure
glyph.
[0049] FIG. 11 illustrates a trademark glyph having three
functionalities: (1) trademark function (its shape), (2) an RFID
antenna function, and (3) a secure glyph function for
authenticating an object or product according to the authentication
system and method of the present invention.
[0050] FIG. 12 shows a trademark glyph having various printed
colors therein specified by known color specification systems and
formed from two different printing ink formulations where at least
one printing ink formulation contains a machine readable covert
taggant to be read by an authentication reader.
[0051] FIG. 13 shows the spectral reflectance factors for two
principal colors of the printing ink formulations used to print the
trademark glyph of FIG. 12.
[0052] FIG. 14 shows the spectral reflectance factors for two
principal colors of the printing ink formulations containing a low
concentration of methylene blue as the covert machine readable
taggant used to print the trademark glyph of FIG. 12.
[0053] FIG. 15 shows the different emission intensities of a diode
laser used to excite the methylene blue machine readable down
converter taggant present in the colored portions of the trademark
glyph of FIG. 12, along with two different printed film layer
thicknesses for the printing ink formulations containing the
taggant.
[0054] FIG. 16 shows a Level 1 security measure trademark glyph,
printed with a conventional printing ink formulation. The trademark
glyph is visible to the human eye and machine readable with an
optical character reader or a camera used as the authenticating
apparatus.
[0055] FIG. 17 shows a printed trademark glyph where the machine
readable features is a printing ink formulation containing a
taggant to be read by an authentication reader.
[0056] FIG. 18 shows a printed trademark glyph where the machine
readable features is a printing ink formulation containing a
taggant to be read by an authentication reader.
[0057] FIG. 19 shows a printed trademark glyph where the
intellectual property protected feature is recognized as a
combination of a conventional printing ink and a machine readable
printing ink formulation containing a taggant to be read by an
authentication reader.
[0058] FIG. 20 shows a printed trademark glyph where the machine
readable features are printing ink formulations containing
different taggants to be read by an authentication reader.
[0059] FIG. 21 shows another version of the printed trademark glyph
in FIG. 19 where the intellectual property protected feature is
recognized as a combination of a conventional printing ink and a
machine readable printing ink formulation containing a taggant to
be read by an authentication reader.
[0060] FIG. 22 shows yet another version of the printed trademark
glyph in FIG. 19 where the intellectual property protected feature
is recognized as a combination of a conventional printing ink and a
machine readable printing ink formulation containing a taggant to
be read by an authentication reader.
[0061] FIG. 23 shows a printed trademark glyph where the machine
readable feature is a printing ink formulation containing a taggant
with a taggant ink overlay.
[0062] FIG. 24 shows a printed trademark glyph where the machine
readable feature is a printing ink formulation containing a taggant
with a taggant ink overlay.
[0063] FIG. 25 represents a trademark printed by prior art
techniques. More specifically, a trademark (i.e. an intellectual
property feature) is printed with a conventional printing ink
formulation where a machine readable overlay coating (eg containing
a taggant) is subsequently applied. Therefore, the trademark itself
is not printed such that it is capable of being recognized alone as
a machine readable feature. An authenticating apparatus could not
be used to authenticate the trademark since any machine read by the
apparatus of the machine readable feature in the overlay and would
not, in any way, be associated with the intellectual property
protected feature.
[0064] FIG. 26 shows a represents a secure glyph where the
intellectual property protected feature is comprised of two
distinct machine readable features: (1) a conventional printing ink
overlaid with an ink containing a taggant; and (2) an ink overlay
containing a taggant. The intellectual property protected feature
would be recognized via a combination of the two machine readable
features upon interrogation by an authenticating apparatus.
[0065] FIG. 27 shows a represents a secure glyph where the
intellectual property protected feature is comprised of three
distinct machine readable features: (1) a conventional printing ink
overlaid with an ink containing a taggant; (2) a combination of two
taggant inks used to represent a portion of the intellectual
property feature of the secure glyph; and (3) an ink overlay
containing a taggant. The intellectual property protected feature
would be recognized via a combination of the three machine readable
features upon interrogation by an authenticating apparatus.
DETAILED DESCRIPTION
[0066] The present invention provides a secure glyph, an object or
product with a secure glyph thereon, a method of producing the
object or product, an authenticating apparatus, a device
incorporating the authenticating apparatus, a process for
manufacturing the device, a method for authorizing and/or allowing
the use of the object or product with the machine and thus a
preventing or inhibiting the use of an unauthorized/non authentic
object or product and an authentication method.
[0067] Attempts have been made to prevent the use of an
unauthorized object or product by positioning an identifier, either
on the object or product directly or on a substrate associated with
the object or product such as a lid or label, which can be detected
by the detector. Thus the use of the object or product is only
permissible when the authentication reader recognizes the
identifier.
[0068] It had previously been thought that an identifier employing
a Level 2 security measure was unique and/or constituted trade
secret information and could not be hacked, copied or otherwise
reproduced. However, a problem arises when the identifier can be
reproduced, even if periodically reconfigured or reformulated, to a
required degree of accuracy to enable unauthorized producers,
suppliers and/or dealers to position the identifier onto a non
authentic object or product to be detected by a detector and
thereby allow the use of the non authentic object or product with a
device.
[0069] Furthermore even if the identifier is the subject of patent
protection, such as a unique taggant formulation, it is then
difficult and very involved to prove that anyone reproducing such a
formulation is, in fact, infringing the patent.
[0070] The present invention solves the above mentioned problem by
employing a secure glyph having a machine readable feature and an
intellectual property protected feature that can be employed to
prove infringement of the intellectual property feature of the
secure glyph and enable the owner of the intellectual property
right to prove the counterfeiting or unauthorized copying or
reproduction of the object or product.
[0071] Therefore unauthorized producers, suppliers and/or dealers
attempting to reproduce the secure glyph are deterred from doing so
given they would immediately become liable for the unauthorized use
of the intellectual property feature of the secure glyph and
subject themselves to intellectual property infringement
proceedings and the associated remedies upon counterfeiting,
copying or reproducing and/or using the secure glyph.
[0072] Thus the present invention is capable of extending the life
span of the security protection measure, such as a taggant subject
to utility patent protection, afforded a trademark owner, given
that in most cases, utility patent protection is limited to a 20
year lifespan, whereas trademark protection has an unlimited life.
This particular aspect is advantageous given that it is not
uncommon for an object or product to have a marketplace life span
that exceeds the life span of any utility patent coverage for an
object or product in the marketplace.
[0073] The term "glyph" as used herein defines an elemental symbol
having a design feature within an agreed set of symbols, intended
to represent a readable (e.g. machine readable) feature for the
purposes of writing and thereby expressing or conveying thoughts,
ideas and concepts. Glyphs are considered to be unique marks that
collectively can add up to the spelling of a word or otherwise
contribute to a specific meaning of what is written, with that
meaning dependent on cultural, social and/or societal usage.
[0074] The term "secure glyph" as used herein defines an element
that has an intellectual property protected feature and a machine
readable feature.
Intellectual Property Protected Feature
[0075] The intellectual property protected feature is herein
defined as a feature that is represented and protectable or is
protected by, for example, at least one intellectual property
right, such as a trademark, trade secret, copyright or a registered
design.
[0076] In particular, the intellectual property protected feature
of the glyph may, for example, be a copyrighted jingle that is
immediately played upon interrogation of the glyph by an
authenticating apparatus.
[0077] The intellectual property protected feature is preferably
recognizable by at least one unassisted human sense. Thus the
intellectual property protected feature may be visually
recognizable with the human eye, audibly recognizable, olfactory
recognizable and/or recognizable by touch. When the intellectual
property protected feature is recognizable by at least one
unassisted human sense it is considered to be "overt".
Alternatively, recognition of the intellectual property protected
feature may require the use of a detector when it cannot be
recognized by at least one unassisted human sense and is thus
considered "covert". The intellectual property protected feature
may also comprise an overt and/or a covert portion.
[0078] In particular, the intellectual property protected feature
could be a phrase or slogan that is protected by copyright, a
scent, image or design protected by a trademark or a trade
secret.
[0079] Usually, the intellectual property protected feature is
recognizable with the naked eye and preferably is the subject of a
registered trademark.
[0080] Wherein the intellectual property protected feature is a
trademark the secure glyph is considered a "trademark glyph" which
is a particular type of secure glyph, specifically designed to be
representative of a registered trademark, trade name or logo, and
that is, or is capable of being, affixed or attached, printed or
coated and/or incorporated into an object or product requiring
authentication.
[0081] The intellectual property protected feature and the machine
readable feature may each be recognized alone, or in combination or
association with each other by an authenticating apparatus to
determine authenticity of the secure glyph.
[0082] The intellectual property protected feature may be
recognized by the authentication reader based on its shape,
geometry and/or symmetry.
[0083] In a particular embodiment of the invention at least one
machine readable feature is either positioned within the
intellectual property protectable feature, constitutes the entire
intellectual property protected feature or constitutes only a
discrete portion or section of the intellectual property protected
feature.
[0084] The machine readable feature of the secure glyph may also
have an overt portion and/or a covert portion.
Secure Glyph
[0085] In a further embodiment of the present invention the entire
secure glyph may constitute an intellectual property protected
feature which may be formed from a machine readable feature.
[0086] The secure glyph in its entirety may be invisible to the
"naked eye" i.e. when both the intellectual property protected
feature and the machine readable feature both only have covert
portions or may be visible to the "naked-eye" i.e. when either the
intellectual property protected feature and/or the machine readable
feature have at least one overt portion.
[0087] Furthermore the secure glyph may be any geometrical form or
pattern such as a mark, trademark, logo, character, alphanumeric,
drawing, picture, semiotic, pictogram, hieroglyph, symbol, image,
geometric object and/or an embossed or deformed area.
[0088] The secure glyph design typically has a sufficiently high
degree of rotational symmetry, also known as "n-fold rotational
symmetry" such that the position of the secure glyph is not
critical to its recognition.
[0089] Wherein the authentication reader is capable of reading only
a single pixel or very few pixels of information, then the secure
glyph would require an infinite number of degrees of rotational
symmetry, such as a circular dot or ring, whilst the authentication
reader is capable of reading 2 or 3 pixels could reliably recognize
a regular hexagon, which would have six degrees of rotational
symmetry.
[0090] Preferably, the secure glyph has at least 3 degrees of
rotational symmetry, more preferably at least 4 degrees of symmetry
and advantageously at least 6 degrees of rotational symmetry.
[0091] Thus in one embodiment of the present invention the secure
glyph comprises a plurality of features of sufficiently high degree
of rotational symmetry such that one or all may be read by the
authentication reader.
[0092] Examples of secure glyphs having a regular polygonal shape
are shown in FIGS. 7 and 8 whilst a secure glyph having a star
shaped regular polygonal shape is shown in FIGS. 5 and 6.
[0093] Consequently a secure glyph shaped as shown in FIGS. 7 and 8
can be read at a plurality of points regardless of orientation,
whereas a secure glyph shaped as shown in FIGS. 5 and 6 a positive
recognition requires the correct orientation.
[0094] Alternatively the secure glyph may be designed so as to lack
rotational symmetry. Secure glyphs lacking in rotational symmetry
include: numbers, letters, words, marks, characters (including, but
not limited to, those used to represent words in Chinese, Japanese
and Korean languages), hieroglyphs (including those, for example,
used to represent words in ancient Egyptian), pictograms and the
like.
Authentication Reader
[0095] In one embodiment of the present invention, the
authentication reader will read the entire secure glyph.
[0096] However, in an alternative embodiment the authentication
reader will only read certain points or sectors of the secure glyph
and this allows for a greater expression in the design of the
secure glyph and for reprogramming the authentication apparatus to
sample different areas of the secure glyph, either in response to
counterfeiting or in response to a change in the secure glyph or
another readable security feature of the secure glyph.
[0097] Advantageously, the secure glyph is provided with a means to
normalize its orientation, such as an orientation mark or symbol so
that the authentication reader recognizes the secure glyph in a
consistent manner.
[0098] This normalization can be accomplished by providing a
further reader that reads a fixed point, line or shape appearing at
another location on the object or product and providing a means to
compute the relative orientation and location of the secure glyph
by coupling the readings together.
[0099] Furthermore, the secure glyph may consist of a physical
structure that exhibits different heights from the surface of the
object or product, a so-called 3D effect and the reader detects the
location of the secure glyph at varying heights above the surface
of the object or product.
[0100] One non-limiting example of this embodiment is a concave
mirror (circular, paraboloidal or elliptical) which, when
interrogated with light, will have the property of refocusing said
light back to a point or to a line. Another non-limiting embodiment
is a microlens array that when interrogated with light,
particularly, but not limited to the visible wavelength light,
there will be a definite reflected pattern of light that may be
used both to authenticate and to visualize the secure glyph.
Machine Readable Feature
[0101] The machine readable feature is typically selected from
upconverters, downconverters, infra-red radiation absorbers,
quantum dots, RFID antennae, fluorescent compositions, liquid
crystals, electro-kinetic materials, thermochromic materials,
photochromic materials, piezochromic materials, sonochemicals,
magnetic materials such as ferromagnetic, antiferromagnetic,
ferrimagnetic, and paramagnetic materials, combinations of dyes or
pigments readable by multispectral imaging, materials readable by
Raman spectroscopy and combinations thereof.
[0102] Preferably, suitable machine readable features may be formed
from materials such as fluorescent dyes, pigments, nano particles
that are visible or invisible in natural or room light, dyes such
as silicon 2,3-naphthalocyanine bis(trihexylsilyloxide), and/or
other metal complexed naphthalocyanine compounds, and/or other
cyanine, naphthocyanine or phthalocyanine dyes; glass encapsulated
nanoparticles such as CdTe, CdSe, PbS, PbSe, InAs; phosphors such
as YAG:Nd, Al.sub.2O.sub.3:Nd, and/or various other phosphor based
IR active nanoparticles.
[0103] Advantageously, the machine readable feature is preferably
made of fluorescent taggant materials that produce an emission
spectrum or signal response when the secure glyph is exposed to a
certain excitation source, such as electromagnetic frequencies,
e.g. X-ray, UV (Ultraviolet) light, visible light or IR (Infrared)
light. The emission spectrum may be in the UV, visible or IR
spectral ranges.
[0104] The material or materials for the machine readable feature
may be organic or inorganic and may be a solid, such as a powder, a
liquid, and/or a solid dissolved in a liquid or form a suspension
or dispersion in a liquid. Each fluorescent taggant material will
have its own characteristic excitation pattern and emission
spectrum.
[0105] A combination of secure glyphs using different materials, in
different ratios, having, for example, different characteristic
excitation patterns and emission spectrums, or the cascade of the
emission spectrum of one secure glyph to excite the emission
spectrum of a second secure glyph may also be used as the machine
readable feature.
[0106] As a further example, a mixture of materials for the machine
readable feature may have the same or different excitation
wavebands and thus when a mixture of taggant materials is used, not
only are the individual emission peaks of each material considered,
the whole spectrum profile for that particular mixture is also
important.
[0107] Thus, even for a single peak emission, emission amplitudes
of neighboring wavelengths may also be measured and taken into
account. In addition, for some fluorescent taggant materials,
employed in the invention, the dynamic characteristics of the
emission, such as the emission response time and decay time may
also constitute a significant secure glyph verification
criteria.
[0108] Machine readable features of the secure glyphs that are
covert, i.e. invisible to the naked-eye, include irreversible
thermochromic or photochromic taggant materials. These taggant
materials are typically interrogated by irradiation using a reader
having a suitable and appropriate type of heat or light source that
would render the secure glyph visible to the naked-eye due to a
physical change in the state or property of the taggant
material.
[0109] Typically, secure glyphs that are invisible to the naked-eye
include ultraviolet-active photoinitiators. Together with an
ultraviolet-crosslinkable component incorporated therein these
taggant materials, upon irradiation with a suitable and appropriate
ultraviolet light source, become visible to the naked-eye as a
result of the photoinitiation and the change in the refractive
index of the taggant material.
[0110] Furthermore, secure glyphs that are invisible to the
naked-eye and, interrogated by a reader singularly or in a
plurality of ways or having more than one type of readable
features, may be formed from rare earth oxides or sulfides. These
taggant or other types of machine readable materials, when
interrogated by electromagnetic radiation display both upconversion
and downconversion readable properties. A non-limiting example of a
secure glyph displaying down conversion properties would be a
combination of a colored pigment having unique spectral
characteristics with a Raman-active secure glyph such as that
described in U.S. Pat. No. 6,610,351.
[0111] It will be appreciated by one of ordinary skill in the art
that incorporating a taggant material into a secure glyph that
provides for a change in the reader visualization of the secure
glyph during interrogation, need not be the sole security or
authenticating feature offered by the secure glyph.
[0112] The secure glyphs of the present invention may be
interrogated by an authentication reader in more than one manner,
e.g. either as a singular secure glyph or plurality of secure
glyphs or by incorporating one or more of the above-mentioned
taggants into the secure glyph.
[0113] In a further embodiment of the present invention, there may
be one or more secure glyphs present on the object or product which
may be the same or different in their design or in the type of
secure glyph or readable security feature each possesses.
[0114] Furthermore at least one additional secure feature may be
positioned on or in association with the object or product.
[0115] In particular the at least one additional secure feature may
be a second secure glyph or it may be a secure feature
interrogatable by the same or different means as the first secure
glyph. The additional secure feature may be read by the same reader
as the secure glyph or it may be read by a second device either
remote from or integral to the first reader.
[0116] One advantage of this particular embodiment is that a
counterfeiter of the secure glyph will not be able to use
counterfeit object or product because the authenticating apparatus
will still recognize the object or product as non-authentic. It
will be appreciated that the authenticating apparatus may be
configured, under these circumstances either to overall reject the
object or product as non-authentic, or to accept the visualization
of the counterfeited secure glyph, and so display the trademark or
other intellectual property comprised in the secure glyph. This
would render the counterfeiter an unauthorized user of a trademark
or other intellectual property associated with the glyph.
Method for Producing Objects or Products
[0117] The present invention also provides an object or product
with a secure glyph thereon and a method of producing the object or
product.
[0118] The object or product is typically a beverage dispenser cup,
a lid, cover or label.
[0119] The secure glyph may be incorporated into the object or
product during its manufacturing process by mixing a taggant
material used to form the machine readable feature of the secure
glyph into the raw materials of the object or product and thus the
machine readable feature becomes an integral part of the object or
product.
[0120] In particular, when the taggant material used is a powder,
it may be mixed with plastic beads, fillers or adhesives or
incorporated into substrates such as textiles, woven fabric,
non-woven fabric, thread fibers, cardboard, concrete, polymer,
glass, wood, paper (including currency, certificates, licenses,
identification cards, and passports) metal, plastic, ceramic, cloth
and leather.
[0121] Alternatively, the secure glyph may be embossed onto an
object or product, or attached to the object or product with an
adhesive.
[0122] Preferably the secure glyph is printed or coated onto the
surface of an object or product using a printing ink, paint, epoxy
or lacquer.
[0123] A combination of the above-mentioned application techniques
may be employed.
Authentication
[0124] The present invention also provides an authenticating
apparatus which comprises a database containing data that
corresponds or is associated with a signal response generated from
an authentic intellectual property protected feature alone, or in
combination with the machine readable feature and an authentication
reader.
[0125] Preferably, the authentication apparatus includes an output
device and advantageously a display unit.
[0126] The authentication reader comprises a signal generator
capable of generating a signal response from the intellectual
property protected feature alone, or in combination with the
machine readable feature, a signal response detector capable of
receiving the signal response from the intellectual property
protected feature alone, or in combination with the machine
readable feature and a signal processing unit (SPU) for comparing
the signal response from the detector and the stored signal
response in the database.
[0127] The authentication reader plays a critical role in the
authentication method, as it acquires information from the secure
glyph and conducts an analysis, based on the acquired information,
to authenticate the object or product.
[0128] Advantageously, the acquired information may be stored in
the database and may also be communicated e.g. via the internet to
the brand owner of the object, or any other legitimate interested
party. Furthermore the information obtained by the brand owner or
other legitimate interested party may be analyzed and
advantageously used to teach the authenticating apparatus improved
means of recognizing the authenticity of the secure glyph on the
object or product.
[0129] Additionally, the acquired information may also be used to
provide a response signal to a communication device associated with
the user of the object or product, such as sending a text message
via Bluetooth to a smartphone informing them of a prize they have
won, or directing them to a website of particular interest.
[0130] In one particular embodiment of the invention the
authentication reader may detect and recognize a signal response
that is representative of the entire intellectual property
protected feature of the secure glyph and thus the authentication
reader is considered to be in possession of the secure glyph and
thus in possession of the intellectual property protected feature
as well.
[0131] This is the case, for example, wherein the machine readable
feature of the secure glyph is, in itself, in the form of a
trademark and when the authentication reader reads the secure glyph
it is also reading and using the secure glyph as the trademark that
appears on the object or product.
[0132] Alternatively, the authentication reader may detect and
recognize a signal response that is associated with the
intellectual property protected feature and which is then compared
with associated data (such a signal response) in the database
whereupon the entire intellectual property protected feature of the
secure glyph is generated and thus only the authentication
apparatus as a whole is considered to be in possession of the
secure glyph and the intellectual property protected feature.
[0133] Advantageously, in both scenarios, the intellectual property
protected feature can optionally be displayed on a display unit of
the authentication apparatus, which may be remote or local to the
location of the secure glyph itself.
[0134] The signal generator of the authentication reader includes
an excitation source that usually provides at least one light
source such as a UV and/or an IR light source.
[0135] Furthermore the signal generator may include an excitation
delivery source, such as light optics, a focusing lens, color
filters, reflectors and optical fibers for optimized delivery to
the detector.
[0136] The signal response detector of the authentication reader
may include a multispectral image analyzer (hyperspectral image
analyzer) capable of analyzing light from the visible and
non-visible portions of the electromagnetic spectrum.
[0137] Preferably, the multispectral analyzer is an RGB (red,
green, blue) sensor, used to collect the RGB components of the
signal response.
[0138] The RGB sensor has output channels for the R, G and B
components and the total signal intensity (W) and provides the
color of the signal responses and the total signal intensity to
indicate signal concentration as illustrated in FIGS. 2 and 4. The
sensor output can either be in voltage, current or pulse frequency
format.
[0139] Furthermore the RGB sensor provides for three progressive
levels of security in the analysis of the RGB signal emission
profiles namely, the wavelengths where the emission intensity
peaks, the peak wavelengths and the relative amplitudes of the peak
emission intensity wavelengths and the peak wavelengths of the
relative intensity amplitudes at the peak wavelengths and
amplitudes of the emission intensity at "all" wavelengths.
[0140] The emission intensities over the complete emission spectrum
may be digitized to form a bar graph where the amplitude and the
width of each bar is recorded and used for analysis of the signal
response by the SPU. Where the complete emission spectrum for a
secure glyph in the visible range is obtained, the emission color
can also be calculated to serve as an additional authentication
characteristic of the secure glyph. In addition, a fast response
spectrometer can be set to be proportional to signal emission
intensities to give one more dimension to the authentication
algorithm.
[0141] Yet another layer of authentication protection may also be
provided by using a response time RGB sensor wherein one can record
the response time (rise time and/or decay time) of the signal
response and set it as another authentication readable feature
criteria. In such an embodiment, the database record would contain
data for a particular secure glyph's name-RGB values, intensity,
decay time-product information.
[0142] When the secure glyph is visible to the naked-eye such as
multi-colored glyph, then the intensity of the color signals
emitted from the secure glyph can also be used to identify the
secure glyph. The reflected light intensity will be proportional to
the area of the secure glyph within the aperture of the reader.
Thus using three or four colored sources, such as light emitting
diodes, aimed at an area of the secure glyph, the fraction of the
light sensed or read will be proportional to the area of the secure
glyph printed in that color. Thus, the ratio of the R to G to B
response signals will form a unique identifier for the secure
glyph, without having to process the complete image of the secure
glyph. Such area average identification could be defined during the
design of the secure glyph on a printing plate, for example, where
the area or where the secure glyph or other secure materials placed
on the object or product can be determined independently from the
rest of the graphics on the object or product as illustrated in
FIGS. 9 and 10.
[0143] In another embodiment of the present invention, a
spectrometer is used as the signal response detector to provide a
high level of security. The use of such a high level detector
would, for example, avoid the problem of metamerism. The signal
response may have output signal intensity in a wide range of
wavelengths and a resolution ranging from several nanometers to
less than 1 nanometer. The use of a spectrometer also allows the
complete emission spectrum profile to be obtained. The selection of
the spectrometer (over applicable wavelength range, sensitivity and
resolution) will depend on the physical and chemical properties and
features of the taggant materials used to form the secure glyph and
the signal emission wavelengths required for authentication.
[0144] In an embodiment of the present invention where a
spectrometer is used, the spectrometer can have a wavelength
dispersive element, able to detect the complete response spectrum
for the secure glyph. The data output of the spectrometer can be in
the form of the relative intensities versus wavelengths, where the
emission peaks are recorded and naturally become the fingerprint of
the readable security feature for the secure glyph.
[0145] In another embodiment of the invention provides object or
product authentication wherein the secure glyph is covert, for
example, using a printing ink, and generates a fluorescent signal
response that results from being excited by an ultraviolet or
infrared excitation source. The signal response generated will be
in three different colors. The authentication reader will typically
perform at least three different spectral characteristics, either
by nature (such as an LED being connected as photodiode) or by the
addition of a color filter that matches the signal response of the
fluorescent colorants used in the taggant material to formulate the
secure glyph.
[0146] The signal response detector is configured to send a signal
response to the SPU. After receiving the signal response, the SPU
performs a diagnostic analysis and retrieves the related secure
glyph property data from the database and compares this with the
signal response received from the signal detector.
[0147] The results of the comparison are then typically sent to an
output device which allows the machine to function or prevents the
machine from functioning. Preferably the output device includes
display unit which provides notification to a user of the result
either audibly, preferably visually.
[0148] The analysis hardware and output device may be a desktop or
notebook computer. Furthermore the output device may be a
standalone mobile application device (field type), having analysis
hardware, an SPU and associated electronic circuitry. The output
could appear on a small liquid crystal display panel, or other type
display. The database may either be built-in to the authenticating
apparatus or be connected to the apparatus via a wired or wireless
means, such as the internet or an intranet.
[0149] The authenticating apparatus may also include one or more
input devices for the user to input commands to direct or interact
with the authentication apparatus. The format for the data
representing the signal emission will depend on the signal emission
detection device used.
[0150] The authentication reader may further generate an output,
which can be connected to an SPU configured for outputting the
result of the authentication, to a manufacturer or user of an
article, object or product subject to the authentication. The
reader may, for example, upon failing to authenticate a trademark
glyph affixed to an article, object or product, send a command to
the authentication apparatus to cause the, object or product or a
device using the article, object or product to cease
functioning.
[0151] It will be appreciated that the value of this authentication
reader functional aspect where a user of a counterfeit, object or
product is attempting to force the use or acceptance of the
counterfeit, object or product. The loss stemming from any failure
to use the object or product or any article or device associated
with the object or product can cause a user to contact the
manufacturer in order for the object, product, article or device to
become functional again.
[0152] By such a means, the manufacturer of the object, product,
article or device can limit counterfeiting and develop data on the
counterfeiting. Thus the lock-out and reporting aspect for the
authenticating apparatus and method of the present invention can be
commercially valuable for ink jet cartridges, pharmaceuticals,
vaccines, beverages and beverage and vending dispensing machines
and many other industrial articles, items and machines of various
types.
[0153] In a further embodiment of the present invention, the
authentication reader may be designed to read and, optionally,
visualize the secure glyph and additionally have the capability to
read numerous pixels of information thereby capturing the shape and
orientation of the secure glyph.
[0154] The visualization could be provided by a miniature camera
that is either monochrome, or full color. In one particular
embodiment, where the entire geometric shape of the secure glyph is
visible to the naked-eye using a camera, there is no requirement
that the secure glyph be designed to have rotational symmetry.
Furthermore the camera captured image can be rotated or processed
using mathematical procedures and image processing.
[0155] Additionally, another layer of authentication protection is
gained when the total signal intensity of a signal response serves
as an additional verification criteria relating to the
concentration of the taggant material forming the secure glyph.
Therefore, for a certain object or product, one may simply double
such concentration to make a difference in the readable features of
the secure glyph.
[0156] The present invention also provides a machine with the above
mentioned authenticating apparatus incorporated therein or
associated therewith.
[0157] The machine could be an injet printer, a vending machine or
a brewing machine.
[0158] The present invention also provides a method for allowing
for an object or product having a secure glyph thereon to be
accepted and used for a specific intended purpose in a machine
associated with the authenticating apparatus as herein described
above.
[0159] The method involves using the authenticating apparatus
incorporated within or associated with a machine to detect and
recognize the intellectual property protected feature alone, or in
combination with at least a portion of the machine readable feature
on a secure glyph and subsequently authorizing or allowing the
intended use object or product in or with the machine.
[0160] Furthermore the method may include initially affixing or
attaching the secure glyph to the object or product, printing or
coating the glyph onto the object or product and/or incorporating
the glyph into the object or product.
[0161] The present invention also provides a system for allowing a
first article to be used in combination with a second article
comprising; [0162] a) authenticating the first article with a glyph
thereon by detecting a characteristic feature of the glyph with a
detector; and [0163] b) allowing the first article to be used in
combination with the second article.
[0164] Advantageously, the glyph is a secure glyph is herein
defined above.
[0165] Finally, the present invention provides an authentication
method for determining the authenticity of an object or product
having a secure glyph thereon comprising:
affixing or attaching thereto, printing or coating thereon and/or
incorporating therein onto the object or product a secure glyph
having an intellectual property protected feature; and a machine
readable feature having a covert, and optionally an overt portion;
wherein said intellectual property protected feature is recognized
either alone as a machine readable feature; or recognized in
combination with at least a portion being a machine readable
feature; by an authenticating apparatus to determine authenticity;
subjecting the object or product with the secure glyph affixed to
an authenticating apparatus to determine authenticity having a
database containing associated data corresponding to a signal
response from an intellectual property protected feature alone, or
combination with a machine readable feature; and an authentication
reader having: a signal generator capable of generating a signal
response from an intellectual property protected feature alone or
in combination with the machine readable feature on the secure
glyph; a signal response detector capable of receiving the signal
response from the intellectual property protected feature alone, or
in combination with the machine readable feature; and a signal
processing unit (SPU) for comparing the signal response from the
detector and the relevant associated data in the database; and
acknowledging the output from the authentication reader.
[0166] In a particular embodiment of the present invention, the
object or product authentication includes applying or incorporating
a secure glyph to the object or product; a database storing data
related to the signal response properties of the secure glyph; and
an authentication reader having a signal generating or excitation
source for emitting a signal towards the secure glyph for a signal
emission or response detection by the reader, and a signal
processing unit (SPU) for analyzing the signal response and
comparing the signal response with the data in the database as
illustrated in FIGS. 1 and 3, thereby verifying the identity and
authenticity of the object or product containing the secure glyph
or having it applied thereto.
[0167] The information so obtained may further either remain stored
in the database or may be communicated, e.g. via the internet to
the brand owner of the object. It is also a feature of this
invention that the information so obtained by the brand owner may
be analyzed and used to teach the reader device improved means of
recognizing the authenticity of the secure glyph on the object.
Another possibility is to program the reader device to seek a
secondary authentication measure for the object. These features are
of special utility when (a) a counterfeiter uses an authentic
object of the owner, containing an authentic secure glyph, where
the reader and/or human have little reason to not believe that
object and secure glyph are authentic, or (b) a counterfeiter
produces a close match to the secure glyph that might fool the
reader and/or human into believing that the close match to said
secure glyph is in fact authentic. By either of these means, false
positives can be detected or avoided and the apparatus reading the
secure glyph can be taught to differentiate between forgeries and
authentic secure glyphs or be taught to reference some other
information that has been input into the reader device to further
enhance or improve its ability to recognize the authenticity of
secure glyphs and the objects containing them.
[0168] The information so obtained from the data base may also, in
this instance, be conveyed to the police or to another local or
governmental security organization, in order to apprehend
counterfeiters and eradicate counterfeiting and unlawful uses and
representation of trademarks, trade names, copyrighted materials
and other intellectual property.
[0169] If the readable feature of a trademark glyph for determining
a counterfeit trademark that is used on or in association with an
object or product is visible to the naked eye, trademark
infringement could be established immediately by the owner of the
object or product. If the readable feature of the trademark glyph
is hidden to invisible to the naked eye, then a secondary exposure
source would be required to visualize the trademark glyph at some
point during or throughout the use of the object or product. A
hidden or invisible trademark glyph would add yet another level of
authentication security to an object or product, since it would not
be immediately clear to the counterfeiter why their counterfeit
object or product is being rejected and unacceptable, even though
it would appear to look and function the same, and contain the same
readable features as the authentic object or product. Also, a
hidden or invisible trademark glyph would preferably not impede the
view or appearance of any other marketing or decorative design or
advertising appearing on the object or product.
[0170] The important and distinct advantage the present invention
provides, is that the authentication apparatus is not only looking
for the presence of a naked-eye visible and reader visible feature
of the secure glyph applied on the object or product for
authentication, but is also simultaneously or sequentially looking
to visually identify and authenticate the secure glyph itself as,
for example, a trademark, trade name or logo, where such visual
identification offers another level of verification and
authentication for the object or product.
[0171] In another embodiment, a secure or trademark glyph is hidden
or invisible and is subsequently visualized to the naked-eye by use
of a reader that interrogates the secure glyph and displays the
trademark glyph on a remote analog or digital display screen
associated or part of the object or product. In this fashion, the
trademark glyph is still connected with the object or product it is
intended to represent and provides for a secondary visual
validation of the secure or trademark glyph during the
authentication of the object or product containing the trademark
glyph. Optionally, display of the secure or trademark glyph may be
accompanied by a validating, safety or advertising message or
signal, for example "authentic product" or "good to consume" or
"caution when handling hot beverages", "call this number for a free
sample" or a check mark or smiley face, appearing on the display
screen, in monochrome or full color. Those of ordinary skill in the
art will realize that other messages, codes and signals, including
those that may represent monetary value, can be generated by using
the secure or trademark glyph of the present object and product
authentication apparatus. Further optionally, the display of a
secure or trademark glyph may be used following normal use of the
object to verify the remains of said object in order to derive
further value for the consumer of said object, for example by
proving that the object qualifies for a rebate or a gift.
[0172] In a further embodiment, the secure or trademark glyph is
hidden or invisible and printed on an interior surface of an object
or product. For example, the interior surface of a laminated
flexible packaging material, wherein the assembly is substantially
transparent through at least one surface, to facilitate a means of
interrogating the hidden or invisible trademark glyph. Through at
least the one transparent surface, that is also substantially
transparent to visible radiation, a secure or trademark glyph
comprised of a fluorescent taggant material can be subjected to
excitation at wavelengths of infra-red radiation that the secure or
trademark glyph absorbs. The secure or trademark glyph may also be
applied as an adhesive, rather than a printing ink, on the
substrate of the object or product in such fashion as to accurately
represent the geometric design of the secure or trademark
glyph.
[0173] The present invention has been described in detail,
including the preferred embodiments thereof. However, it will be
appreciated that those skilled in the art, upon consideration of
the present disclosure, may make modifications and/or improvements
on this invention that fall within the scope and spirit of the
invention. The following examples illustrate specific aspects of
the present invention and are not intended to limit the scope
thereof in any respect and should not be so construed.
Example 1
Authentication of an Overt Secure Glyph on an Object
[0174] A glyph for an object was provided having an n-fold
rotational symmetry of 4 and which the intellectual property
protected feature was visible to the naked-eye by applying a
printing ink or coating containing a taggant onto the object by
known application methods.
[0175] The object was then interrogated by a handheld machine
reader and authentication conducted by both the naked-eye and the
reader.
Example 2
Authentication of a Covert Trademark Glyph on an Object and Use
with a Machine
[0176] A trademark glyph was provided having an n-fold rotational
symmetry of 4 and which was invisible to the naked-eye by applying
a printing ink or coating onto the lid of the single use beverage
dispensing cup to create the design and form of the trademark.
[0177] The beverage dispensing cup is inserted into a beverage
dispensing machine or brewer, where upon insertion, the trademark
glyph becomes visible to the naked-eye. The beverage dispensing cup
is then subjected interrogation by an authentication apparatus
incorporated within the machine and the trademark glyph is
displayed a visual display on the dispensing machine.
[0178] Upon interrogation, the beverage dispensing cup is subjected
to identification and authentication by the machine reader and the
process of using the beverage dispensing cup either continues or is
halted based on the results of the authentication for the trademark
glyph appearing on the lid of the beverage dispensing cup.
[0179] Upon authorization of the trademark glyph, the beverage
dispenser continues its operation and a beverage is brewed and
dispensed.
[0180] At the point where the authentication occurs and is
verified, the trademark glyph causes a trademark, logo or message
to appear on the display screen of the dispensing machine, and
additionally a message such as `ENJOY YOUR GENUINE BREW" or
"AUTHENTICALLY BREWED" is also displayed.
[0181] The trademark, logo or message continues to appear on the
machine's display screen throughout the brewing and dispensing
process until completion. The spent brewing cup may then be taken
to a second authentication center, where, upon presentation of said
spent cup to a second reader, a rebate or prize may be offered to
the holder of the spent cup. Upon non-verification of the trademark
glyph, the dispensing machine does not brew or dispense a beverage
and a message appears on the display screen notifying the user. The
unused counterfeit beverage dispensing cup is then either deposited
in a repository, or otherwise held or rejected.
Example 3
Authentication of an Overt Trademark Glyph on an Object and Use
with a Machine
[0182] A trademark glyph for an ink-jet cartridge for use in an
ink-jet printer was provided which was visible to the naked-eye. A
printing ink or coating containing a secure glyph is patterned
deposited onto an ink-jet printer cartridge to create the design
and form of the trademark glyph using a known application
methods.
[0183] Trademark glyph design can be any shape because the ink-jet
cartridges preferably may only be inserted into the printer in one
way, so the orientation of the cartridge is mandated by the
printer.
[0184] The ink-jet cartridge is then inserted into a printer and
subjected to a means for interrogating the trademark glyph by a
reader.
[0185] Upon interrogation of the trademark glyph, the ink-jet
cartridge is subjected to identification and authentication by the
reader and the process of using the ink-jet cartridge in the
printer either continues and accepts the ink from the cartridge or
does not accept the ink and the printer will not print.
[0186] Optionally, the printer may be further be disabled, either
temporarily or permanently until an authentic ink-jet cartridge has
been authenticated by the reader. A further option could require
that a message be sent from the printer, for example, via the
internet, or a digital or analog screen display, to alert the user
or manufacturer of the printer about the non-verification.
Example 4
Authentication of a Covert Trademark Glyph on an Object and Use
with a Machine
[0187] A trademark glyph for an ink-jet cartridge for use in an
ink-jet printer is designed to be invisible to the naked-eye. A
printing ink or coating containing a secure glyph is patterned
deposited onto an ink-jet printer cartridge to create the design
and form of the trademark glyph using a known application
method.
[0188] The trademark glyph design can be any shape because the
ink-jet cartridges preferably may only be inserted into the printer
one way, so the orientation of the cartridge is mandated by the
printer. The ink-jet cartridge is then inserted into a printer.
Upon insertion into a printer, the trademark glyph becomes visible
to the naked eye and is subjected to a means for interrogating the
trademark glyph by a reader, wherein the reader is a handheld,
machine readable, or visual display, or a combination thereof.
[0189] Upon interrogation of the trademark glyph, the ink-jet
cartridge is subjected to identification and authentication by the
reader and the process of using the ink-jet cartridge in the
printer either continues and accepts the ink from the cartridge or
does not accept the ink and the printer will not print.
[0190] Optionally, the printer may be further be disabled, either
temporarily or permanently until an authentic ink-jet cartridge has
been authenticated by the reader. A further option could require
that a message be sent from the printer, for example, via the
internet, or a digital or analog screen display, to alert the user
or manufacturer of the printer about the non-verification.

Example 10
Authentication of an Overt Trademark Glyph on an Object and Use
with a Machine
[0218] A secure glyph, which also functions as a passive RFID
(radio frequency identification) antenna is designed such that the
intellectual property protected feature is visible to the naked-eye
and have an industry common geometric shape and configuration
typically seen for a standard RFID antenna (shown in FIG. 11). The
secure glyph, also carries the functionality of a passive RFID
antenna. The secure glyph is applied to a substrate or object as a
laminated structure of aluminum or copper. Alternately, the secure
glyph is formulated from a silver or copper conductive material,
printed in the geometric shape and configuration on a substrate or
object then cured by a standard curing method. The secure glyph is
capable emitting a signal response when interrogated by a reader
emitting radiation of, for example, a frequency of 13.56 MHz. Upon
interrogation, the secure glyph and the object to which it is
attached are authenticated by the reader. The output signal from
the reader upon authenticating the secure glyph may, optionally,
enable a copyrighted message, a trademark, or a trade name to
display on a screen, or enable copyrighted musical notes to be
played by a device interacting with the object to which the secure
glyph is applied.
Example 11
Production of a Trademark Glyph Containing an Overt Intellectual
Property Protected Feature and a Covert Machine Readable
Feature
[0219] One embodiment of the present invention (shown in FIG. 12)
provides a registered trademark of the DIC Corporation of Tokyo
Japan as a colored trademark glyph containing a light green colored
area behind the letter "d", a light blue colored area behind the
letter "c" and a 2-color mixture that produces a medium blue-green
area behind the letter "I".
[0220] The spectral reflectance factors of the light green color
(PMS 7487) and the light blue color (PMS 298) over the visible
portion of the electromagnetic spectrum for the trademark glyph
were recorded (see FIG. 13). The spectral reflectance for the same
two colors, overprinted with an ink containing fluorescent taggant
(i.e. methylene blue) at low concentrations (so as not to markedly
affect the two visual colors that downconverts, were also recorded
(see FIG. 14). Each recording was made using an ISO 13655 compliant
spectrodensitometer.
[0221] A small "blip" or upturn in the long wavelength tail of each
color's spectral curve can be observed. This is due to the emission
of the covert taggant machine readable portion of the trademark
glyph and stems from when the methylene blue dye is excited with a
high intensity solid state laser authenticating apparatus with a
central frequency of 650 nm.
[0222] When the laser is not activated, the curves appear as they
normally would. When the laser is active additional radiance is
emitted from the print with the methylene blue dye and the
long-wavelength "blip" signature is captured.
[0223] Finally, FIG. 15 shows the radiant emission as a second
machine readable feature of the trademark glyph when the
spectrodensitometer source, as measured by the authenticating
apparatus, is not activated wherein the location of the laser
excitation being reflected and the methylene blue emission from an
unprinted portion of the substrate can be clearly seen.
Furthermore, two different thicknesses produce different emission
intensities as fluorescence which appears as a fairly linear
process, as measured by the authentication apparatus.
[0224] The example shows that a trademark glyph, according to the
present invention, can be printed on an object or product and thus
allowing for a method to establish and verify that the trademark
was printed and used by an authorized supplier or user of the
object or product.
