[0067] The display unit 110 displays a UI image. Here, the UI image
may include various content reproducing images such as an image, a
moving picture, a text, music, etc., an application execution image
including various contents, a web browser image, a graphic user
interface (GUI) image, or the like.
[0068] In this case, the display unit 110 may be embodied as, but
is not limited to, a liquid crystal display panel (LCD), an organic
light emitting diode (OLED), or the like. In addition, the display
unit 110 may be embodied as a flexible display, a transparent
display, or the like as necessary.
[0069] In particular, the display unit 110 may display a text input
UI in response to a preset event for text input to the electronic
apparatus 100 occurring. Here, the preset event may correspond to
the case in which a user command for searching or information input
is input in response to a user command for generation (or
connection) of a user account being input. The text input UI may be
a UI including a plurality of text items and a plurality of
function items (e.g., enter, space, etc.) and may be embodied as a
virtual keyboard. In addition, in the present invention, a text may
be interpreted as a concept including various characters that may
be input to a machine and used, such as a language such as Korean,
English, Japanese (hiragana and katakana), Chinese character,
Chinese, Roman alphabets, Greek alphabets, etc., a symbolic
character such as a number, various symbols, etc. or a graphic
character, a unit character indicating various units, a rule
character, etc.
[0070] The communication unit 120 may communicate with various
types of external devices or external servers according to various
types of communication methods.
[0071] In particular, the communication unit 120 communicates with
the user terminal apparatus 200 (refer to FIG. 1) to receive
various user commands. Here, when the electronic apparatus 100 is
embodied as a digital TV, the communication unit 120 may be
embodied as a remote control receiver for receiving a remote
control signal from the user terminal apparatus 200. Here, the
remote control receiver may perform communication according to
various communication methods such as WiFi communication, Bluetooth
communication, infrared communication, etc.
[0072] In response to a text input UI including a plurality of text
items being displayed, the communication unit 120 may receive a
user command for selection of one of a plurality of text items from
the user terminal apparatus 200.
[0073] In response to a text input UI being displayed according to
an event for generation of a user account, the communication unit
120 may receive a user command for selection one of a plurality of
text items included in the corresponding text input UI and
information about a user fingerprint recognized based on the
corresponding user command, which will be described below in
detail
[0074] The controller 130 controls an overall operation of the
electronic apparatus 100.
[0075] In particular, upon receiving information corresponding to a
user fingerprint recognized based on a user command for text input
from the user terminal apparatus 200 in a preset text input mode,
the controller 130 may store information corresponding to the user
fingerprint as authentication information associated with the
corresponding preset text input mode.
[0076] Here, the preset text input mode may be a text input mode
provided according to an event for generation of a user account.
For example, when the electronic apparatus 100 provides different
services for respective users, to this end, the electronic
apparatus 100 may provide a text input mode for generation of a
user account, to this end. Here, the user account may be generated
based on an ID (e.g., a user E-mail address) and a password input
by a user. However, the present invention is not limited thereto.
Needless to say, a name, a telephone number, an SNS account, etc.
may also be required to generate an account according to
information required during account generation.
[0077] In this case, the controller 130 may store information
corresponding to a fingerprint received from the user terminal
apparatus 200 as authentication information about a user account
generated in a text input mode for generation of a user account and
perform authentication on the corresponding account based on the
stored information when next authentication for the user account is
required.
[0078] That is, in response to a user account being generated via
an account generating image, the controller 130 may store
information corresponding to the user fingerprint received together
as authentication information that replaces an ID and password of a
user and perform authentication using the corresponding fingerprint
information during next authentication. For example, the controller
130 may connect the information corresponding to the received user
fingerprint to the user ID and store the information to perform
user authentication based on the fingerprint input instead of the
password during next authentication.
[0079] However, the present invention is not limited thereto.
However, the text input mode for generation of a user account may
be various text input modes for generation an account such as a
text input mode for generation of an SNS account, a text input mode
for generation an E-mail account, etc. Accordingly, the information
about the user fingerprint received in the corresponding text input
mode may be used as authentication information for login for an SNS
account, an E-mail account, etc.
[0080] The information corresponding to the user fingerprint
received from the user terminal apparatus 200 may be generated
based on information recognized through a fingerprint scan sensor
(or a fingerprint scan module) included in a preset button area
that receives a user command for text input on the text input UI in
the user terminal apparatus 200. For example, the preset button
area may be a button area required for text input, for example, an
area including a confirmation button unit for inputting a text
selected by a selection GUI such as a cursor on the text input UI,
but is not limited thereto. For example, an input button for "@"
required to input an E-mail address may include a fingerprint scan
sensor or a four-direction button area may include a fingerprint
scan sensor.
[0081] In this case, upon entering a text input mode for generation
of a user account, the controller 130 may transmit a corresponding
signal to the user terminal apparatus 200 to activate a fingerprint
scan sensor included in the preset button area.
[0082] That is, while deactivating the fingerprint scan sensor
included in the preset button area, the user terminal apparatus 200
may activate the fingerprint scan sensor only upon receiving a
signal indicating entrance to a user account generating mode from
the electronic apparatus 100.
[0083] However, this is merely exemplary, and thus the fingerprint
scan sensor included in the preset button area may be activated
according to a signal input from the user terminal apparatus 200
itself. For example, when the user terminal apparatus 200 includes
a button for receiving a user command for entrance to a mode for
user account generation, the user terminal apparatus 200 may
activate the fingerprint scan sensor included in preset button area
based on input of the corresponding button and transmit a signal
corresponding to input of the corresponding button to the
electronic apparatus 100 such that the electronic apparatus 100
enters the mode for user account generation. In addition, when the
user terminal apparatus 200 includes a display and is configured to
perform mirroring on a UI image of the electronic apparatus 100 and
to receive a command for controlling the electronic apparatus 100
through the corresponding UI image, the user terminal apparatus 200
may also activate the fingerprint scan sensor included in the
preset button area according to a user command input through the UI
image of the user terminal apparatus 200.
[0084] A plurality of pieces of user fingerprint information
recognized by the user terminal apparatus 200 may be received
whenever a confirmation signal is received according to user input
to a confirmation button area or may be received at one time when a
text input mode for user account generation is ended. In the latter
case, the plurality of pieces of recognized user fingerprint
information may be simply received at one time or one piece of
fingerprint information obtained by integrating a plurality of
pieces of fingerprint information may be received.
[0085] The controller 130 may separately store a plurality of
pieces of fingerprint information received during generation of
user account or may integrate and store a plurality of pieces of
fingerprint information as one piece of fingerprint information. In
the latter case, the controller 130 may analyze a plurality of
pieces of fingerprint information corresponding to at least one
different partial region of user fingers and generate and store one
piece of complete fingerprint information.
[0086] Then the controller 130 may perform user authentication
based on fingerprint information stored in response to a user
authentication event occurring.
[0087] For example, when a plurality of pieces of fingerprint
information are separately stored, it may be determined whether
fingerprint information matched with fingerprint information
received from the user terminal apparatus 200 for user
authentication is present among the plurality of pieces of stored
fingerprint information and fingerprint authentication may be
performed.
[0088] As another example, when one piece of fingerprint
information obtained by integrating a plurality of pieces of
fingerprint information is stored, it may be determined whether
fingerprint information matched with fingerprint information
received from the user terminal apparatus 200 for user
authentication is present from the stored fingerprint information
and fingerprint authentication may be performed.
[0089] FIG. 2B is a block diagram illustrating a detailed
configuration of the electronic apparatus illustrated in FIG. 2A.
As illustrated in FIG. 2B, according to an embodiment of the
present invention, an electronic apparatus 100' includes the
display unit 110, a user interface unit 120, the controller 130, a
storage unit 140, an audio processor 150, and a video processor
160. Among components illustrated in FIG. 2B, a detailed
description of the same components as in FIG. 2A will be omitted
herein.
[0090] An image receiver (not shown) receives image data through
various sources. For example, the image receiver (not shown) may
receive broadcast data from an external broadcaster and receive
image data from an external apparatus (e.g. a DVD or BD player,
etc.).
[0091] The storage unit 140 stores various modules for driving the
electronic apparatus 100. For example, the storage unit 140 may
store software including a base module, a sensing module, a
communication module, a presentation module, a web browser module,
and a service module. In this case, the base module is a basic
module that processes a signal transmitted from each hardware
included in the electronic apparatus 100 and transmits the signal
to a higher layer module. The sensing module may be a module that
collects information from various sensors and analyzes and manages
the collected information and may include a face recognition
module, a voice recognition module, a motion recognition module, an
NFC recognition module, etc. The presentation module is a module
for configuring a display image and may include a multimedia module
for reproducing and outputting multimedia content and a UI
rendering module for performing UI and graphic processing. The
communication module is a module for performing communication with
an external device. The web browser module refers to a module that
performs web browsing to access a web server. The service module is
a module including various applications for providing various
services.
[0092] As described above, the storage unit 140 may store
information corresponding to a user fingerprint received from the
user terminal apparatus 200 as authentication information about a
generated user account in a text input mode for user account
generation.
[0093] Although the aforementioned embodiment has been described
with regard to the case in which information about a user account
and a user fingerprint corresponding to the user account are stored
in the electronic apparatus 100, this is merely exemplary. Thus,
corresponding information may be stored in an external device
connected through a network, for example, an external server.
[0094] The audio processor 150 is a component for performing
processing on audio data. The audio processor 150 may perform
various processes such as decoding, amplification, noise filtering,
etc. on audio data.
[0095] The video processor 160 is a component that performs
processing on image data received by an image receiver (not shown).
The video processor 160 may perform various image processes such as
decoding, scaling, noise filtering, frame rate conversion,
resolution conversion, etc. on image data.
[0096] The controller 130 controls an overall operation of the
electronic apparatus 100' using various programs stored in the
storage unit 140.
[0097] As illustrated in FIG. 2B, the controller 130 includes a
random access memory (RAM) 131, a read only memory (ROM) 132, a
graphic processor 133, the main CPU 134, first to nth interfaces
135-1 to 135-n, and a bus 136. In this case, the RAM 131, ROM 132,
the graphic processor 133, a main central processing unit (CPU)
134, the first to nth interfaces 135-1 to 135-n, etc. may be
connected to each other through the bus 136.
[0098] A command set, etc. for system booting is stored in the ROM
132. Upon receiving a turn-on command to receive power, the main
CPU 134 may copy an operating system (O/S) stored in the storage
unit 140 to the RAM 131 according to a command stored in the ROM
132 and execute the O/S to boot a system. In response to booting
being completed, the main CPU 134 copies various applications
programs stored in the storage unit 140 to the RAM 131 and executes
the application programs copied to the RAM 131 to perform various
operations.
[0099] The graphic processor 133 generates an image including
various objects such as an icon, an image, a text, etc. using a
calculator (not shown) and a rendering unit (not shown). The
calculator calculates a attribute value such as a coordinate value,
a shape, a size, color, etc. for displaying each object according
to layout of an image using a control command received through the
user interface unit 120. The rendering unit generates images of
various layouts including an object based on the attribute value
calculated by the calculator. The image generated by the rendering
unit is displayed in a display area of the display unit 110.
[0100] The main CPU 134 accesses the storage unit 140 and performs
booting using the O/S stored in the storage unit 140. In addition,
the main CPU 134 performs various operations using various
programs, content, data, etc. stored in the storage unit 140.
[0101] The first to nth interfaces 135-1 to 135-n are connected to
the aforementioned various components. One of the interfaces may be
a network interface connected to an external device.
[0102] FIG. 3A is a block diagram illustrating a configuration of
the user terminal apparatus 200 according to an embodiment of the
present invention.
[0103] Referring to FIG. 3A, the user terminal apparatus 200
includes a communication unit 210, an input unit 220, a fingerprint
scanner 230, and a controller 240.
[0104] The communication unit 210 communicates with the electronic
apparatus 100.
[0105] In detail, the communication unit 210 may perform
communication according to various communication schemes such as
WiFi communication, Bluetooth communication, infrared
communication, etc. to transmit a signal corresponding to a user
command input through the input unit 220 that will be described
later to the electronic apparatus 100.
[0106] The input unit 220 receives various user commands for
control of the electronic apparatus 100.
[0107] To this end, the input unit 220 may include a four-direction
button unit, a confirmation unit, a power button unit, etc. The
four-direction button unit may receive a user command for
four-direction manipulation of a selection GUI such as a cursor,
etc. displayed on a UI image provided on the electronic apparatus
100. In addition, the confirmation button unit may receive a user
command for performing a function corresponding to a specific
object in a state in which a cursor is positioned on the
corresponding object on a UI image. For example, in response to a
signal of the confirmation button unit being input in a state in
which the cursor is positioned on a specific text item on a text
input UI, a text corresponding to the corresponding text item may
be input.
[0108] In addition, the input unit 220 may further include various
button units for receiving various user commands required for
control of the electronic apparatus 100, for example, a channel
control button, a volume control button, etc.
[0109] The fingerprint scanner 230 is included in a preset button
area of the input unit 220 preset button area and recognizes a user
fingerprint. Here, the preset button area may be, but is not
limited to, an area in which the aforementioned confirmation button
unit is provided. Fingerprint scan technology is one of biometrics
technologies and is an authentication method of extracting
different pieces of fingerprint information for respective
individuals to make information. Since a fingerprint has property
whereby the fingerprint is not changed as long as a corium part is
not damaged, fingerprint scan is used to recognize individuals. The
fingerprint scan sensor included in the fingerprint scanner 230 may
generate fingerprint data corresponding a fingerprint shape of a
fingerprint that contacts a sensor surface according to the amount
of current that varies while the fingerprint contacts the sensor
surface.
[0110] FIG. 4 is a diagram illustrating an outer appearance of the
user terminal apparatus 200 according to an embodiment of the
present invention.
[0111] As illustrated in FIG. 4, when the user terminal apparatus
200 is embodied as a remote controller, a fingerprint scan sensor
may be provided in an area of a confirmation button unit 410 that
receives a confirmation or selection command. In addition, a
four-direction button unit 420 that receives a user command for
four-direction manipulation may be provided in an area outside the
confirmation button unit 410.
[0112] Based on this configuration, a user may manipulate movement
of a cursor on a text item positioned on an text input UI displayed
on the electronic apparatus 100 through the four-direction button
unit 420 and perform text input on a text item selected by the
cursor through the confirmation button unit 410. Accordingly,
whenever the user selects and inputs a text item, a fingerprint may
be recognized through the fingerprint scan sensor provided in the
confirmation button unit 410 and the recognized information may be
transmitted to and stored in the electronic apparatus 100.
[0113] However, the aforementioned configuration of the user
terminal apparatus 200 is merely exemplary. If necessary, a
fingerprint scan sensor may be disposed in an area of the
four-direction button unit 420 or may be disposed in another button
area that receives a user command required for generation of a user
account.
[0114] FIGS. 5A and 5B are diagrams illustrating a configuration of
a fingerprint scan sensor according to an embodiment of the present
invention.
[0115] According to a fingerprint scan sensor 10 illustrated in
FIG. 5A, in response to a piezoelectric thick film 11 being pressed
by a finger, a current density value at a contact portion is varied
by a pressure 13 according to a fingerprint 12 of the finger. The
current density value may be read by an output line 15 through a
sensing device 14 to recognize the fingerprint 12.
[0116] According to a fingerprint scan sensor 20 illustrated in
FIG. 5B, a principle of a capacitive CMOS sensor is used. That is,
capacitance of a sensor surface 22 and a fingerprint 23 may be
measured and converted into an electrical signal so as to realize a
digital image and to recognize a fingerprint.
[0117] However, the above FIGS. 5A and 5B show an example of the
fingerprint scan sensor. Needless to say, the fingerprint scan
sensor may be embodied in various forms adoptable in the art.
[0118] The controller 240 controls an overall operation of the user
terminal apparatus 200.
[0119] In particular, in response to the electronic apparatus 100
entering a preset text input mode, the controller 240 may recognize
a user fingerprint according to user input to a preset button area
and transmit information corresponding to the recognized user
fingerprint to the electronic apparatus 100. Here, the preset
button area may be a confirmation button area (an area of the
confirmation button unit 410 of FIG. 4) including the
aforementioned fingerprint scanner 230.
[0120] In detail, upon receiving a user command for selection of a
specific text on a text input UI displayed on the electronic
apparatus 100 in a preset text input mode through a preset button
area, the controller 240 may recognize a user fingerprint according
to input and transmit information corresponding to the recognized
user fingerprint to the electronic apparatus 100. Here, the user
terminal apparatus 200 may determine that the electronic apparatus
100 enters a preset text input mode based on a signal received from
the electronic apparatus 100 or an event (e.g., button press for
account generation) generated by the user terminal apparatus
200.
[0121] A preset text input mode for recognition of a user
fingerprint in the preset button area may be a text input mode for
generation of a user account. For example, the user account may
include various user accounts such as a user account for using a
service provided from the electronic apparatus 100, an SNS account,
an E-mail account, etc.
[0122] The controller 240 may control whether the fingerprint
scanner 230 is activated according to whether user fingerprint scan
is required.
[0123] In detail, the controller 240 may activate the fingerprint
scanner 230 in response to a preset event occurring in a state in
which the fingerprint scanner 230 is deactivated.
[0124] In particular, in response to the electronic apparatus 100
entering a text input mode, the controller 240 may activate the
fingerprint scanner 230, and in response to the electronic
apparatus 100 getting out of a preset text input mode, the
controller 240 may deactivate the fingerprint scanner 230.
[0125] In addition, in response to a user authentication event
occurring in the electronic apparatus 100, the controller 240 may
activate the fingerprint scanner 230. When a fingerprint is
registered for a user account and then an authentication event
associated with a corresponding user account occurs, the controller
240 may activate the fingerprint scanner 230.
[0126] In this case, the controller 240 may determine whether the
electronic apparatus 100 enters a preset text input mode and the
user authentication event occurs, based on a signal received from
the electronic apparatus 100. For example, when the electronic
apparatus 100 enters a text input mode for user account generation
or authentication is required for a pre-generated user account, a
signal for activating a fingerprint scan sensor provided in a
preset button area of the user terminal apparatus 200 may be
transmitted to the user terminal apparatus 200.
[0127] However, the present invention is not limited thereto, and
it is possible to activate the deactivated fingerprint scanner 230
according to a user command input from the user terminal apparatus
200. This has been described above and thus a detailed description
thereof will be omitted herein.
[0128] Upon recognizing a user fingerprint in a confirmation button
area, the controller 240 may transmit information corresponding to
a fingerprint recognized whenever the fingerprint is recognized to
the electronic apparatus 100. For example, the controller 240 may
transmit a confirmation signal according to user input to the
confirmation button area together with information about the
recognized fingerprint to the electronic apparatus 100.
Accordingly, the electronic apparatus 100 may receive the
recognized fingerprint information by as much as the number of
received confirmation signals.
[0129] Alternatively, the controller 240 may transmit a plurality
of pieces of fingerprint information recognized in a text input
mode for user account generation at one time in response to the
corresponding text input mode being ended. In this case, although
the controller 240 may simply transmit the plurality of pieces of
recognized fingerprint information at one time, it is possible to
integrate and transmit the plurality of pieces of recognized
fingerprint information as one piece of fingerprint information. In
this case, the user terminal apparatus 200 may store an algorithm
for integrating a plurality of pieces of fingerprint information as
one piece of fingerprint information.
[0130] Accordingly, even if the user does not perform a separate
fingerprint scanning process, a fingerprint for an automatically
generated user account may be recognized and registered.
[0131] FIG. 3B is a block diagram illustrating a detailed
configuration of the user terminal apparatus 200 illustrated in
FIG. 3A. As illustrated in FIG. 3B, a user terminal apparatus 200'
according to an embodiment of the present invention includes the
communication unit 210, the input unit 220, the fingerprint scanner
230, the controller 240, and a storage unit 250. Among components
illustrated in FIG. 3B, a detailed description of the same
components as in FIG. 3A will be omitted herein.
[0132] A detailed configuration of the controller 240 is the same
as that of the controller 130 of the electronic apparatus 100'
illustrated in FIG. 2B, and thus a detailed description thereof
will be omitted herein.
[0133] The storage unit 250 stores various modules for driving the
user terminal apparatus 200'. For example, the storage unit 250 may
store software including a base module, a sensing module, and a
communication module. The sensing module may be a module that
collects information from various sensors and analyzes and manages
the collected information and may include, in particular, a
fingerprint scan sensor.
[0134] In addition, as described above, the storage unit 140 may
store information corresponding to a user fingerprint received from
the user terminal apparatus 200 as authentication information about
a generated user account in a text input mode for user account
generation.
[0135] FIG. 6 is a set of diagrams for explanation of a method of
registering a fingerprint according to text input according to an
embodiment of the present invention.
[0136] As illustrated in FIG. 6(A), it is assumed that a user
generates a user account in the electronic apparatus 100. For
example, as illustrated in FIG. 6(A), the user may generate a user
account for using a service provided by the electronic apparatus
100 according to input of ID and PASSWORD.
[0137] In this case, as illustrated in FIG. 6(B), the electronic
apparatus 100 may provide a text input UI such that a user may move
a position of a cursor 610 on the text input UI to select a desired
text. In this case, the position of the cursor 610 may be moved and
manipulated through a four-direction button of the user terminal
apparatus 200.
[0138] For example, as illustrated in FIG. 6(B), in a state in
which the cursor 610 is positioned on a text item "p" 620, in
response to a confirmation button 420 of the user terminal
apparatus 200 being pressed and manipulated, a character `p`
corresponding to the selected text item "p" 620 may be input to a
text input window 630. In this case, in response to the
confirmation button 420 being pressed and manipulated, a user
fingerprint may be recognized together. As such, the confirmation
button 420 is pressed and manipulated by as much as a text input
number of times and a user fingerprint is recognized by as much as
a pressing and manipulating number of times of the confirmation
button 420.
[0139] As illustrated in FIG. 6(C), in response to PASSWORD for
account generation being input, the confirmation button 420 is also
pressed and manipulated by as much as a text input number of times
and a user fingerprint is also recognized by as much as a pressing
and manipulating number of times of the confirmation button
420.
[0140] For example, as illustrated in FIG. 6(D), when it is assumed
that ID including 5 characters and PASSWORD including 5 characters
are input without correction during user account generation, a user
fingerprint is recognized a text input number of times, i.e. 10
times and 10 pieces of fingerprint information may also be
generated.
[0141] As illustrated in FIG. 6(E), the recognized fingerprint
information may be transmitted to the electronic apparatus 100 and
registered for authentication information for a generated user
account. In this case, the registered fingerprint information may
be one piece of integrated fingerprint information obtained by
integrating 10 pieces of fingerprint information as described, but
if necessary, 10 pieces of fingerprint information may be
separately registered as respective pieces of information.
[0142] Then in response to an authentication event for the
corresponding user account occurring, the registered fingerprint
information may be used as authentication information.
[0143] FIG. 7 is a set of diagrams for explanation of an
authentication method according to registered fingerprint
information in response to an authentication event occurring
according to an embodiment of the present invention.
[0144] FIG. 7(A) illustrates the case in which an authentication
event occurs in the electronic apparatus 100 according to an
embodiment of the present invention. The case illustrated in FIG.
7(A) may correspond to the case in which account login is required
in order to use a service provided by the electronic apparatus
100.
[0145] For example, a UI image (or a UI image that requires ID
input) including icons 711 to 715 indicating respective users may
be provided, and a user may select a specific icon indicating
himself or herself and attempt to login.
[0146] In response to the user selecting a specific item, a
notification message for requesting fingerprint scan may be
provided, as illustrated in FIG. 7(B).
[0147] In this case, the user may perform fingerprint scan through
a preset area of the user terminal apparatus 100, that is, an area
(e.g., a confirmation button area) including a fingerprint scan
sensor for recognizing a fingerprint and perform authentication on
a selected account. In response to an authentication system being
released, a corresponding service image may be provided simply by
selecting a user icon without a separate authentication procedure,
but the present is not limited to this case, and thus a detailed
description thereof will be omitted herein.
[0148] FIGS. 8A and 8B are diagrams for explanation of a method of
registering a fingerprint according to various embodiments of the
present invention.
[0149] As illustrated in FIG. 8A, a plurality of pieces of
fingerprint information recognized whenever a confirmation button
area included in a fingerprint scan sensor is pressed and
manipulated in a user terminal apparatus may be integrated and
stored as one piece of fingerprint information.
[0150] For example, in response to the user pressing and
manipulating the confirmation button area using an index finger, a
position, visibility, etc. of recognized fingerprint information
may be varied based on an actually pressed portion of the index
fingerprint, a pressing strength, a pressing time, etc. One piece
of complete fingerprint information obtained by integrating various
pieces of fingerprint information and corresponding to the index
finger may be generated and stored.
[0151] The fingerprint integrating procedure may be performed by
the electronic apparatus 100, but when the user terminal apparatus
200 includes a corresponding algorithm, the fingerprint integrating
procedure may be performed by the user terminal apparatus 200.
[0152] Alternatively, as illustrated in FIG. 8B, a plurality of
pieces of fingerprint information recognized whenever a
confirmation button area included in a fingerprint scan sensor in a
user terminal apparatus is pressed and manipulated may separately
be stored as respective pieces of fingerprint information.
[0153] In this case, in response to fingerprint information as a
recognition target being received from the user terminal apparatus
200, matched fingerprint information is searched for among a
plurality of pieces of fingerprint information and fingerprint scan
may be performed.
[0154] FIG. 9 is a sequence diagram for explanation of an
operational correlation between the electronic apparatus 100 and
the user terminal apparatus 200 according to an embodiment of the
present invention.
[0155] As illustrated in FIG. 9, in response to the electronic
apparatus 100 entering a mode for user account generation, a text
input UI may be displayed (S910) and a signal indicating that
entrance to the corresponding mode may be transmitted to the user
terminal apparatus 200.
[0156] In this case, the user terminal apparatus 200 may activate a
fingerprint scan sensor included in a preset button area based on a
received signal (S930). Here, the preset button area may be a
button area required for text input, for example, a confirmation
button area.
[0157] Then the user terminal apparatus 200 may perform text scan
based on a user command for input of a specific text on the text
input UI (S940). For example, in response to the confirmation
button area being pressed and manipulated in order to input a
specific text, a fingerprint may be automatically recognized during
corresponding pressing and manipulation.
[0158] Then the user terminal apparatus 200 transmits fingerprint
information recognized by pressing and manipulating the
confirmation button area to the electronic apparatus 100 (S950).
Here, the fingerprint information may be transmitted together with
a signal corresponding to pressing and manipulation of the
confirmation button area, that is, a text input signal, but is not
limited thereto. For example, the fingerprint information may be
transmitted to the electronic apparatus 100 at one time in response
to a corresponding mode being ended.
[0159] The electronic apparatus 100 that receives fingerprint
information from the electronic apparatus 100 registers and stores
the received fingerprint information as authentication information
about a generated user account (S960).
[0160] Then the electronic apparatus 100 may perform authentication
based on registered fingerprint information in response to an
authentication event for a corresponding user account
occurring.
[0161] FIG. 10 is a flowchart of a method of controlling a user
terminal apparatus according to an embodiment of the present
invention.
[0162] In the method of controlling the user terminal apparatus
that performs a remote control function with respect to an
electronic apparatus illustrated in FIG. 10, in response to the
electronic apparatus 100 entering a preset text input mode (S1010:
Y), the user terminal apparatus 200 recognizes a user fingerprint
according to a user command for input of a specific text on a text
input UI (S1020). Here, the preset text input mode may be a text
input mode for user account generation.
[0163] Then information about the recognized user fingerprint is
transmitted to the electronic apparatus 100 (S1030).
[0164] In operation S1020 of recognizing a fingerprint, a user
fingerprint may be recognized according to a user command for input
of ID and PASSWORD in a text input mode for user account
generation.
[0165] In operation 1020 of recognizing a fingerprint, the
fingerprint may be recognized through a fingerprint scan sensor
included in a confirmation button area that receives a user command
for receiving a specific text on a text input UI. In this case, in
response to the electronic apparatus 100 entering a preset text
input mode, the fingerprint scan sensor may be activated. Here,
whether the electronic apparatus 100 enters a preset text input
mode may be determined based on a signal received from an
electronic apparatus.
[0166] In operation S1020 of recognizing a fingerprint, the user
fingerprint may be recognized by as much as a pressing and
manipulating number of times for the confirmation button area, and
a plurality of pieces of fingerprint information corresponding to
the recognized fingerprint may be transmitted to the electronic
apparatus 100.
[0167] FIG. 11 is a flowchart for explanation of a method of
controlling an electronic apparatus according to an embodiment of
the present invention.
[0168] In the method of controlling the electronic apparatus
controlled by the user terminal apparatus illustrated in FIG. 11,
the electronic apparatus 100 displays a text input UI in a preset
text input mode (S1110).
[0169] Then information corresponding to a recognized user
fingerprint is received based on a user command for input of a
specific text on a text input UI from the user terminal apparatus
200 (S1120).
[0170] Then information corresponding to the user fingerprint is
stored as authentication information associated with a preset text
input mode (S1130).
[0171] Here, the preset text input mode may be a text input mode
for user account generation. In this case, in operation S1230 of
storing the authentication information, information corresponding
to a user fingerprint received from the user terminal apparatus 200
may be stored as authentication information about a user account
generated in a text input mode for user account generation.
[0172] The information corresponding to the user fingerprint
received from the user terminal apparatus 200 is stored as
authentication information about a user account, and then the
electronic apparatus 100 may perform authentication based on stored
information in response to an authentication event for a user
account occurring.
[0173] FIG. 13 is a block diagram illustrating a configuration of a
user terminal apparatus 300 according to another embodiment of the
present invention.
[0174] Referring to FIG. 13, the user terminal apparatus 300
includes an input unit 310, a fingerprint scanner 320, and a
controller 330. Here, the user terminal apparatus 300 may be
embodied as various user terminals such as a cellular phone, a
smart phone, a tablet computer, a notebook computer, a terminal for
digital broadcast, a personal digital assistant (PDA), a portable
multimedia player (PMP), a navigation device, etc. That is, the
user terminal apparatus 300 may be embodied as a touch-based
portable terminal that displays a UI image and controls the
displayed UI image via touch interaction. In this case, the user
terminal apparatus 300 may be embodied in the form including a
touchscreen. Accordingly, the user terminal apparatus 300 may
include a touch sensor and may be embodied to execute a program
using a finger or a pen (e.g., a stylus pen). To this end, the user
terminal apparatus 300 may be embodied to include a touch sensor or
optical joystick (OJ) sensor for receiving various types of user
commands.
[0175] The input unit 310 may receive various user commands and may
be embodied to include the aforementioned touch panel or
touchscreen.
[0176] In particular, the input unit 310 may receive a password for
user authentication in the form of touch. Here, the password may be
input in the form of at least one of pattern input and number
input.
[0177] The fingerprint scanner 320 is included in a preset area of
a touch panel unit and recognizes a user fingerprint. Here, the
preset area may be an area to which a pattern or a number is input.
In particular, in response to a GUI for guiding password input
being displayed through a touchscreen, the preset area may be
provided in an area in which the corresponding guide is displayed.
That is, the preset area may be an area in which a GUI for guiding
pattern input is displayed or an area in which each number is
displayed in a number input UI, but is not limited thereto. That
is, the preset area may be any area as long as the area includes at
least the corresponding area.
[0178] The controller 330 may perform user authentication based on
a password input through a touch panel and compare fingerprint
information acquired during password input with a pre-stored
fingerprint information to perform additional authentication.
[0179] In detail, the controller 330 may perform initial
authentication based on an input pattern or number in a pattern
recognition mode or a number recognition mode and compare
fingerprint information acquired during pattern or number input
with pre-stored fingerprint information to perform additional
authentication. Here, the pattern recognition mode or the number
recognition mode may be a mode for recognition of a pattern or
number input in order to release a lock state (or a lock screen) of
the user terminal apparatus 300.
[0180] The controller 330 may acquire user fingerprint information
in at least one of a touch point in which pattern input is begun in
a pattern recognition mode, a touch point in which a direction is
changed during pattern input, and a touch point in which pattern
input is terminated. For example, in response to a pattern "Z"
being input, the controller 330 may acquire user fingerprint
information in at least one of a first touch point in which pattern
input is begun, a second touch point in which a direction is
changed to diagonal direction drag from right direction drag, a
third touch point in which a direction is changed to left direction
drag from diagonal direction drag, and a fourth touch point in
which pattern input is terminated. However, the controller 330 may
acquire user fingerprint information in at least one touch point
(for example, in the case of four-digit password, a touch point in
which a first number and a last number are input) in which a number
is input in a number recognition mode. However, the present
invention is not limited thereto. Needless to say, user fingerprint
information may be acquired in all touch points in which a number
is input.
[0181] In addition, the controller 330 may acquire user fingerprint
information based on pattern input for pattern registration in a
pattern registration mode for pattern authentication and store the
acquired fingerprint information as the pre-stored fingerprint
information. Here, the pattern registration mode refers to a mode
for initially (e.g., through as a setting menu) registering in
order to use pattern input via a user authentication method.
Needless to say, the same fact may also be applied to a number
registration mode.
[0182] When user fingerprint information is not normally acquired
in a pattern registration mode, the controller 330 may provide GUI
feedback, voice feedback, haptic feedback, etc. for guiding the
corresponding fact. That is, the controller 330 may guide the
corresponding fact to normally register a fingerprint in order to
appropriately recognize the fingerprint in a pattern registration
mode when the fingerprint is not normally acquired. For example,
the controller 330 may provide guidance for re-requesting a pattern
number (number input) due to fingerprint recognition error or
guidance for requesting to maintain touch input for a preset time
period. However, needless to say, the guidance may be provided in
the aforementioned pattern recognition mode. In addition, the same
fact may also be applied to a number registration mode or a number
recognition mode. Although not illustrated, the user terminal
apparatus 300 may further include a display unit (not shown). When
the display unit (not shown) is combined with the aforementioned
touch panel, the display unit may be embodied in the form of
touchscreen. The display unit (not shown) displays a UI image.
Here, the UI image may include various content reproducing images
such as an image, a moving picture, a text, music, etc., an
application execution image including various contents, a web
browser image, a graphic user interface (GUI) image, or the
like.
[0183] In particular, the display unit (not shown) may provide a
GUI for guidance of a password in a preset input mode. Here, the
preset input mode may include at least one of a password
registration mode for authentication and a password recognition
mode for authentication. In this case, a password may be input in
the form of pattern or number (or text). Accordingly, in response
to a password being input in the form of pattern, a GUI (e.g., a UI
including 9 points) for guidance of pattern input, and in response
to a password being input in the form of number (or text), a GUI
(i.e., a number (or a text)) for guidance of number input may be
provided.
[0184] In addition, the user terminal apparatus 300 may further
include a storage unit (not shown) for storing a pattern, a
password, a fingerprint, or the like registered for user
authentication, a communication unit (not shown), an audio output
unit (not shown), etc., which are similar to those of FIG. 3B, and
thus a detailed description thereof will be omitted herein.
[0185] As described above, according to another embodiment of the
present invention, fingerprint authentication (physical
authentication) and pattern (or password) authentication (cognitive
authentication) may be simultaneously input to provide a simple
authentication method with reinforced security.
[0186] FIGS. 12A and 12B are diagrams for explanation of a method
of providing a guide GUI according to an embodiment of the present
invention.
[0187] FIG. 12A shows a state in which GUIs 1211 to 129 for
guidance of pattern input are provided in a pattern authentication
mode, and FIG. 12B shows a state in which GUIs 1221 to 1230 for
guidance of number input are provided in a number authentication
mode.
[0188] Although not illustrated in the diagram, a fingerprint
sensor may be provided in an area in which the GUIs 1211 to 1219
for guidance of pattern input are displayed or the GUIs 1221 to
1230 for guidance of number input. The fingerprint sensor may be
provided on each sub area in which each GUI is displayed or on an
entire area including a sub area in which each GUI is
displayed.
[0189] FIG. 14 is a diagram for explanation of a pattern
registering method according to another embodiment of the present
invention.
[0190] In FIG. 14, for convenience of description, it is assumed
that a pattern with a shape "Z" is registered.
[0191] As illustrated in FIG. 14, in response to a first line being
input (1410), a fingerprint is acquired at a last touch point of
the first line, that is, a touch point in which a direction is
changed to a line "/" from a line "--" (1420). In this case, a
preset touch needs to be maintained at a touch point in which the
fingerprint is recognized, and this fact may be provided to a user
in various forms such as a notification window, a voice, or the
like.
[0192] Then in response to a second line being input (1430), a
fingerprint may be acquired at a last touch point of the second
line, that is, a touch point in which a direction is changed to a
line "--" from a line "/" (1440).
[0193] Then in response to a last line being input (1450), a
fingerprint may be acquired at a touch point of the last line, that
is, a touch point in which pattern input is completed (1460).
[0194] Then in response to pattern input being completed (1470), a
fingerprint input during pattern input may be registered as
authentication information together with a pattern "Z" (1480).
[0195] However, when a fingerprint is not appropriately recognized,
a voice message or a notification window for feeding back this fact
may be provided to a user. In addition, when a fingerprint is
appropriately recognized, feedback (e.g., GUI feedback, haptic
feedback, voice feedback, etc.) may also be provided.
[0196] FIG. 15 is a diagram for explanation of a pattern
registering method according to another embodiment of the present
invention.
[0197] FIG. 14 shows a pattern registration procedure in a terminal
with a wide input area, and FIG. 15 shows a pattern registration
procedure in a terminal with a small input area. That is, in a
small area, a simple direction pattern instead of text form pattern
may be used.
[0198] For convenience of description, in FIG. 15, it is assumed
that consecutive patterns of directions ".fwdarw., .theta., and
.rarw." are registered.
[0199] As illustrated in FIG. 15, in response to a first direction
pattern (.fwdarw.) being input (1510), a fingerprint may be
acquired at a last touch point of a first direction pattern
(1520).
[0200] Then in response to a second direction pattern (.dwnarw.)
being input (1530), a fingerprint may be acquired at a last touch
point of a second direction pattern (1540).
[0201] Then in response to a last direction pattern (.rarw.) being
input (1550), a fingerprint may be acquired at a touch point of a
last direction pattern (1560).
[0202] Then in response to pattern input being completed (1570), a
fingerprint recognized during pattern input may be registered as
user authentication information together with direction patterns
".fwdarw., .dwnarw., and .rarw." (1580).
[0203] FIGS. 16A and 16B are diagrams for explanation of a pattern
authentication method using the pattern registering method
described with reference to FIG. 14.
[0204] As illustrated in FIG. 16A, in response to a pattern being
input for user authentication, a fingerprint may be acquired at a
touch point in which pattern input is terminated, and user
authentication may be performed through the input pattern and a
fingerprint acquired during pattern input.
[0205] As illustrated in FIG. 16B, a fingerprint may be acquired at
a touch point in which pattern input is begun, and user
authentication may be performed through the input pattern and the
fingerprint acquired during pattern input.
[0206] However, FIGS. 16A and 16B show an embodiment of the present
invention. A fingerprint for user authentication may be acquired at
both a touch point in which pattern input is begun and a touch
point in which pattern input is terminated or acquired at another
touch point (a touch point in which a direction is changed).
[0207] FIG. 17 is a diagram for explanation of a pattern
authentication method using the pattern registering method
described with reference to FIG. 15.
[0208] As illustrated in FIG. 17, in response to a direction
pattern being input for user authentication, input of the direction
pattern may be completed, a fingerprint may be acquired via touch
input, and then user authentication may be performed through the
input direction pattern and the acquired fingerprint. However, this
is merely exemplary, and needless to say, a user fingerprint may be
simultaneously acquired with direction pattern input.
[0209] FIG. 18 is a flowchart of a method of controlling a user
terminal apparatus according to another embodiment of the present
invention.
[0210] According to the method of controlling a user terminal
apparatus illustrated in FIG. 18, first, a password for user
authentication is input using a touch method (S1810).
[0211] Then user authentication is performed based on the input
password and additional authentication is performed based on
fingerprint information acquired while the password is input using
the touch method (S1820).
[0212] Here, a password authentication method may include at least
one of a pattern authentication method and a number authentication
method.
[0213] The controlling method may further include displaying a
guide GUI for guidance of password input, and a fingerprint sensor
for fingerprint scan may be provided in an area in which the guide
GUI is displayed.
[0214] When the password authentication method is a pattern
authentication method, in operation S1820, user fingerprint
information may be acquired in at least one of a touch point in
which pattern input is begun, a touch point in which a direction is
changed during pattern input, and a touch point in which pattern
input is terminated.
[0215] In addition, when the password authentication method is a
pattern authentication method, the controlling method may further
include acquiring user fingerprint information based on pattern
input for pattern registration in a pattern registration mode for
pattern authentication and storing the acquired fingerprint
information as reference fingerprint information for fingerprint
authentication.
[0216] In addition, when user fingerprint information is not
normally acquired in a pattern registration mode, a UI for guidance
of the corresponding fact may be provided.
[0217] According to the aforementioned various embodiments of the
present invention, fingerprint registration is automatically
performed by naturally connecting an ID and a fingerprint during
text input for ID/PW required for account generation or pattern (or
number) input through pattern authentication (or number
authentication), and thus a separate procedure for fingerprint
registration does not have to be performed. Accordingly, a simple
user authentication method with reinforced security may be
provided.
[0218] The electronic apparatus and the user terminal apparatus
according to the aforementioned various embodiments of the present
invention may be embodied as a program and the program may be
provided to the electronic apparatus.
[0219] In detail, in response to the electronic apparatus entering
a preset text input mode, there may be provided a non-transitory
computer readable medium for storing a program including
recognizing a user fingerprint according to a user command for
input of a specific text on a text input UI, and transmitting
information corresponding to the recognized user fingerprint to the
electronic apparatus.
[0220] Here, the non-transitory computer readable media refers to a
medium that semipermanently stores data and is readable by a device
instead of a medium that stores data for a short time period, such
as a register, a cache, a memory, etc. In detail, the
aforementioned programs may be stored and provided in the
non-transitory computer readable media such as CD, DVD, hard disc,
blue ray disc, USB, a memory card, ROM, etc.
[0221] The foregoing exemplary embodiments and advantages are
merely exemplary and are not to be construed as limiting the
present invention. The present teaching can be readily applied to
other types of apparatuses. Also, the description of the exemplary
embodiments of the present invention is intended to be
illustrative, and not to limit the scope of the claims, and many
alternatives, modifications, and variations will be apparent to
those skilled in the art.
