Description
FIELD OF THE INVENTION
[0001] The present invention relates to client-server
communication, and more specifically, to using an independent
intermediary mechanism between a client and a server.
BACKGROUND
[0002] The World-Wide Web (WWW, W3, the Web) is an Internet
client-server hypertext distributed information retrieval system.
An extensive user community has developed on the Web since its
introduction.
[0003] FIG. 1 is a block diagram of a prior art client-server
system. The client A 110 can access destination servers DS1-DS3
150-170. Similarly, other clients B and C, 120 130, can access the
destination servers DS1-3 150-170. Each destination server may
provide different services, information, or other data to the
user.
[0004] On the Web everything (documents, menus, indices) is
represented to the user as hypertext objects in hypertext markup
language (HTML) format, or as Java, or JavaScript objects, or other
data types. Hypertext links refer to other documents by their
uniform resource identifiers (URIs). The client program, known as a
browser, e.g. NCSA Mosaic, Netscape Navigator, runs on the user's
computer and provides two basic navigation operations: to follow a
link or to send a query to a server. Users access the web through
these browsers.
[0005] Users often access the web from multiple locations. Users
may access the web from their office, at different locations at
work, at home, or on the road. Libraries and Internet cafes make
web access available on a walk-in basis as well.
[0006] A user accesses a server by typing the URI of the server
into the browser's address window. The browser then connects to the
server corresponding to this URI. Another method of accessing a web
site is by selecting the web site from list of bookmarks. The list
of bookmarks is resident in the browser in the user's computer.
Thus, if a user wishes to have similar bookmarks on multiple
computers, he or she must manually copy the bookmarks and transfer
them between the computers. This process is inconvenient.
[0007] Furthermore, many servers use cookies to store information
about the user. This information may include the user name,
password, previous interests, etc. These cookies are also stored in
the user's browser. Again, this means that if the user is accessing
the Internet from multiple computers, the user's cookies have to be
duplicated into multiple computers. This process is
inconvenient.
[0008] Many users have multiple accounts on different computer
systems. For example, a user may have an account with a bank, an
e-mail account, a personalized portal site account, and an account
on an e-commerce server. Currently, the users must log into each of
these accounts by remembering and providing his or her user name
and password. For security, each of these user names and passwords
should be different. Remembering different names and passwords is
inconvenient to the user. Thus, a method for a simple log-in into
various accounts from any computer would be advantageous.
[0009] Most clients and servers support "forms" which allow the
user to enter arbitrary text as well as selecting options from
customizable menus and on/off switches. As more business is
transacted on the Web, forms are proliferating. The forms may
include forms for requesting further information, for ordering
items from the Web, for registering for a Web site, etc. However,
the user generally can not get a copy of the information filled
into the form. The user can either print the page when the form is
filled in, generating a paper copy, or rely on the server to
respond in a manner that permits the user to make a record of the
information entered in to the form. A method of tracking
information filled into forms would be advantageous. Furthermore,
vendors may respond with an order number or other useful
information. The user can keep a copy of this page, is generally
only temporarily available, by printing it, or copying down the
information provided. A method of attaching this vendor response to
the original order information and making both available to the
user would be advantageous.
[0010] Furthermore, currently, the user has to fill out each of
these forms separately. Generally, the forms request the same types
of information, i.e. name, address, telephone number, e-mail
address, etc. The user has to enter all of this information for
each form. This is repetitious and takes time. Additionally, if
such information as credit card number or social security number is
requested, the user has to pull out the credit card and copy a long
string of numbers. This makes errors likely. Furthermore, the user
has to verify that a Web site that requests a credit card number or
similar confidential information is of the appropriate level of
security for the user to feel comfortable sending the information
over the Web. An improved method of filling out forms would be
advantageous.
SUMMARY OF THE INVENTION
[0011] A method and apparatus of a client-server independent
intermediary mechanism (IIM) is described. The method comprises
displaying a frame including a user interface of the IIM (IIM
frame), and a second frame framing a destination server display
area (DSDA). The method further comprises retrieving data for
display from a destination server, and instrumenting the data prior
to display such that future data retrieved from a destination
server is displayed in the DSDA, without writing over the IIM
frame.

DETAILED DESCRIPTION
[0036] A client-server independent intermediary mechanism is
described. The independent intermediary mechanism (IIM) mediates
information exchanged between a client and servers by having the
client-server communication pass through the IIM. This allows the
IIM to offer various services. For one embodiment, the IIM may be
used to have a central web-accessible set of bookmarks. The IIM may
further provide tracking of transactions on the web, providing a
user-accessible transaction record. The IIM may further be used to
fill in various forms automatically. The IIM may further be used to
access multiple accounts, such as e-mail accounts, bank accounts,
etc. with a single button. The IIM may further be used to store the
user's profile, including passwords to various pages, etc. These
and other uses of the IIM are described below.
[0037] FIG. 2 is a block diagram of one embodiment of the
client-server system including the independent intermediary
mechanism. Multiple clients A-C 210, 215, 220 access multiple
destination servers (DSs) 280, 285, 290, through the independent
intermediary mechanism (IIM) 250. Client A 210 is described as an
example. It is to be understood that multiple clients are
implemented in similar ways.
[0038] Client A 210 accesses the IIM 250. For one embodiment, this
occurs when the user of the client A 210 accesses the web site
hosting the IIM 250. When the IIM 250 is accessed, a new client
component (CC) 230 is established. The client component(s) 230,
235, 240 and the server component 260 together form the IIM 250.
For one embodiment, the IIM 250 is located on a server accessed by
the client A 210 through an Internet connection. For another
embodiment, the IIM 250 is located within the local Intranet of
client A 210. For yet another embodiment, the IIM 250 is located on
the client's own computer.
[0039] For one embodiment, the client component 230 is established
on the local computer of the client 210. For another embodiment,
the client component 230 is on a server, or on a third computer
system. The client component 230 is created in response to the
client 210 connecting to the IIM 250.
[0040] The client A 210 has a connection to the server component
260 through the client component 230. For one embodiment, the
client A 210 also establishes a direct connection with the server
component 260. This direct connection may be used to communicate
certain information directly between the server component 260 and
the client A 210. The client 210 accesses the destination servers
DS1-3 280, 285, 290 through the IIM 250. For one embodiment, all of
the communication between the destination server DS1 280 and the
client A 210 is routed through the IIM 250. For another embodiment,
certain communications are routed directly between the client A 210
and the destination server 280. For example, certain large images
that do not invoke other images or other data may be routed
directly in order to speed up processing.
[0041] The number of client components 230, 235, 240 depends on the
number of clients 210, 215, 220 coupled to the server component 260
at any one time. For one embodiment, the server component 260
consists of multiple components that act together. A block diagram
of one embodiment of the IIM 250 may be found in FIG. 4, below.
[0042] FIG. 3A is a block diagram of one embodiment of the
client-server system including multiple independent intermediary
mechanisms 350, 360. Each IIM 350, 360 is shown having a
corresponding server component, 355, 365. For another embodiment,
the server components 355, 365 may be located on a single server,
or within a single IIM. Having server components 355, 365 coupled
together may serve multiple purposes. For example, if a single IIM
350 has too many users connected to it, the IIM 350 may redirect
users to a second IIM 360. For another embodiment, a user may log
on to a local IIM 350, for speed reasons, and the local IIM 350 may
connect to the user's "home" IIM 360 to retrieve the user's data.
For yet another embodiment, the user can connect to their "home"
IIM 350, which is remote, and the "home" IIM 350 may redirect the
user to a local IIM 360 and send the user's data to the local IIM
360. In this way, the user's connection to the IIM 350, 360 may be
optimized.
[0043] FIG. 3B is a block diagram of another embodiment of the
client-server system including multiple independent intermediary
mechanisms. In this example, a client 310 is coupled to two IIMs
350,360. Generally, the client 310 first connects to the first IIM
350. Then, through the user interface of the first IIM, the client
310 connects to the second IIM 360. This may be advantageous if,
for example, the first IIM 350 and second IIM 360 provide different
services. Thus, for example, one IIM 360 may provide additional
account management features, while the other IIM 350 provides
form-fill features. By connecting to both IIMs 350, 360, in series,
the user has access to the features provided by both IIMs 350,
360.
[0044] FIG. 4 is a block diagram of one embodiment of the
independent intermediary mechanism. The IIM 400 has three layers.
The lowest layer of the IIM 400 is the core engine 410. The core
engine 410 includes a server component SC and a client component
CC. The Server Component, for one embodiment, is resident on the
server, and handles all remote actions. The Client Component, for
one embodiment, is resident on the client's system, while the
client is connected to the IIM 400. For one embodiment, the client
component is automatically removed from the client's system when
the client disconnects from the IIM 400. The lowest layer also
includes a Cookie Manager 413, for managing any cookies received
from and being sent to the destination server. The use of such
cookies is discussed in more detail below. Furthermore, the lowest
layer may include a Activation Manager 416. The Activation Manager
416 determines if information is being transmitted by the
destination server. For one embodiment the Activation Manager 416
further determines if information is being initiated by a user's
action. Information transmitted between the DS and the client is
instrumented by the IIM 400, as will be described below. The
Activation Manager 416 detects when the IIM 400 should review
communication between the client and the DS.
[0045] The second layer is the application/UI framework layer 420.
The application/UI framework layer 420 establishes the basic user
interface and IIM engine. The application/UI framework layer 420
creates a persistent frame for the IIM 400. For one embodiment, the
application/UI framework layer 420 further includes an
instrumenting manager 425, for instrumenting data flowing from the
destination server to the client, through the IIM 400. This process
of instrumenting is described in more detail below.
[0046] The third layer is the applications layer. The applications
layer includes multiple applications. The applications listed here
are listed as an example, and are not a complete list. The
applications layer, for example, may include a Navigation Manager
430. The Navigation Manager 430 permits a user to navigate from
destination server to destination server using the IIM 400. The
applications layer may further include a Transaction Manager
440.
[0047] The Transaction Manager 440 tracks the user's transactions,
stores them, and makes them available for the user's review.
Transactions are interactions in which a user submits information
to a destination server, for example to order an item, ask a
question, or otherwise interact with the destination server. The
Transaction Manager 440 tracks the data submitted by the user, and
any response from the destination server, and permits the user to
access this information.
[0048] The Account Manager 450 permits the user to log into a
variety of accounts, from e-mail to stock trading accounts, using a
single click. The Account Manager 450 further permits the user to
add accounts to this list. The Form Manager 460 permits the user to
fill out forms encountered on destination servers via a single
click. This is extremely useful for users that transact business on
the web, and often fill out identical forms many times. The Profile
Manager 470 is the database of the user's personal information.
This information may be edited by the user, and is used to fill in
forms via the form manager 460. The Database Manager 480 manages
the various databases of the IIM 400.
[0049] The Bookmark Manager 490 permits the user to manage
bookmarks maintained within the IIM 400. Having bookmarks, URIs of
pages the user wishes to save, available in the IIM 400 permits the
user to access his or her bookmark list from any computer.
[0050] The History Manager 495 permits the user to manipulate the
history list of sites the user has previously visited. For one
embodiment, the user can change the permanence of the history
lists, for another embodiment, the user can delete certain sites
from the history list.
[0051] The Homepage Manager 497 permits the user to set a homepage
that is displayed when the user initially connects to the server
providing the IIM 400.
[0052] As can be seen, the IIM provides multiple functionalities. A
single IIM 400 may include all of the functionalities described
above, additional functionalities, or some subset of these
functionalities. The IIM's functionality may be extended with
additional features.
[0053] FIG. 5 is a block diagram of one embodiment of the layout of
the user interface of the independent intermediary mechanism. The
client browser application window 510 is displayed by a browser,
such as Netscape Navigator or Microsoft Internet Explorer. The
client side display area (CSDA) 520 is the display area available
in the browser application window 510. Most browsers have a toolbar
and other displays within the browser application window 510. For
one embodiment, the IIM is designed to minimize the area of the
browser application window that is not the CSDA 520.
[0054] The CSDA 520 includes a toolbar frame 530. Although the tool
bar frame 530 is referred to as a frame, for one embodiment, the
tool bar frame 530 may be implemented in a non-frame format. For
one embodiment, the tool bar may be implemented as a separate
window. For another embodiment, the tool bar may be implemented as
part of the display, not as a frame.
[0055] The CSDA 520 further includes a destination server display
area (DSDA) 540. The DSDA 540 is the area in which all information
from destination servers is presented.
[0056] The CSDA 520 further includes a communications frame 550.
The communications frame 550 is for communication between the
client side and server side of the IIM. Generally, the
communications frame 550 is hidden from the user's view. Thus, the
user would not see the communication between the client component
and the server component.
[0057] FIG. 6 is a flowchart of an overview of using the
independent intermediary mechanism. At block 610, the user connects
to the IIM through the client browser. For one embodiment, this is
done by typing the address of the IIM into the address window of
the browser. For one embodiment, the IIM may be the preset homepage
of the user, or a bookmark in the client browser.
[0058] At block 615, the user connects to a destination server (DS)
through the IIM. For one embodiment, this is done by typing the
address of the destination server into the address window of the
IIM. For another embodiment, the user may select an address from a
history list of previously visited sites, from a bookmark list in
the IIM, or the destination server may be a preset homepage in the
IIM. The IIM records the DS in the history database. The history
database tracks the web sites that the user has visited in the
past. Such a history database may be useful to permit backtracking,
or to visit previously visited sites. For one embodiment, this
history database is maintained for a fixed duration of time, or a
user preset period of time. For another embodiment, the history
database is maintained indefinitely.
[0059] At block 620, the process changes the reference to DS to go
through the IIM and load the information from the DS in the DSDA,
maintaining the IIM frame. This is described in more detail
below.
[0060] At block 625, the IIM determines whether the user submitted
information to the destination server. For one embodiment, the
actual test is whether information that is "sensitive" or "of
interest" is submitted to the DS. For example, if a user selected a
radio button for the next display, the response would be "no" even
though some information was submitted. For one embodiment, the
answer to this query is yes only if information that is in the
user's profile is submitted. For one embodiment, the answer to this
query is provided by the user through the user interface. If the
answer is yes, the process continues to block 630.
[0061] At block 630, the user's communication with the DS is
recorded in the user's transaction database. For example, if the
user ordered an item from a destination server site, the form that
was filled in by the user, including all of the information filled
in, would be recorded in the transaction database. This transaction
database is available to the user. The process then continues to
block 635. If, at block 625, the answer was no, the process
continues directly to block 635.
[0062] At block 635, the IIM forwards the communication, i.e. the
information submitted by the user, to the DS. This communication
includes relevant cookies. A cookie is a packet of information sent
by a destination server to a browser and then sent back by the
browser each time it accesses that server. Cookies can contain any
arbitrary information the server chooses and they are used to
maintain state between otherwise stateless transactions. Generally,
cookies are maintained in a user's browser. However, for one
embodiment, the IIM maintains the user's cookies. This permits a
user to log into a site, and have the appropriate cookies
available, no matter from what web client device or client browser
the user accesses the site.
[0063] At block 640, the process determines whether the destination
server responded to the user's submission of information. For one
embodiment, some destination servers respond, with a thank you
page, other data pertaining to order number, shipping code,
delivery date, etc., when information is submitted to them. If the
destination server responds at block 640, the process continues to
block 645.
[0064] At block 645, the DS's response is recorded in the user's
transaction database, and associated with the user's submitted
information. Thus, when the user reviews the transaction, he or she
can review the entire transaction, including the DS's response.
[0065] At block 650, the IIM instruments the DS's response, stores
any cookies returned by the DS, and forwards the response to the
client browser. One embodiment of this process is illustrated in
more detail in FIG. 7, below. Tables of some results of the process
of instrumenting are illustrated in FIGS. 16A-C, and FIGS.
17-19.
[0066] At block 655, the process tests whether the user continues
to browse through the IIM. The user continues to browse, the
process returns to block 615. Otherwise, the process ends at block
660.
[0067] FIG. 7 is a flowchart of one embodiment of the process of
instrumenting data displayed from a destination server through the
independent intermediary mechanism. For one embodiment, FIG. 7 is a
more detailed flowchart of block 650, in FIG. 6. At block 705, the
IIM receives a communication from the DS. For one embodiment, this
occurs in response to a user contacting a DS through the IIM.
[0068] By block 710, the process tests whether there is a cookie or
multiple cookies associated with the communication. Cookies may be
sent by the DS to the client, to be stored on the client browser.
If a cookie is associated with the communication, the process
continues to block 715. At block 715, the IIM cookie database is
updated with the new cookie. For one embodiment, cookies sent by
the DS to the client browser are handled through the IIM. Thus, the
IIM would store all of the cookies for a DS, and give the DS its
cookies. This is advantageous because it permits a user to access a
DS from any computer, and all of the user's cookies are immediately
available through the IIM. The process then continues to block 725.
If no cookies were associated with the communication, the process
continues directly to block 725.
[0069] At block 725, the process parses the code to find the next
keyword. For one embodiment, keywords are tags in HTML, or known
keywords in Java or JavaScript. FIGS. 16-19 illustrate some
examples of keywords that may trigger this process. For another
embodiment, keywords may be any triggering signal that indicates
that an action may be performed.
[0070] At block 730, the process tests whether a keyword was found.
If no keyword was found, the process continues to block 735, and
ends. If the communication has no remaining keywords, the document
has been fully instrumented, and is ready for display to the user.
For one embodiment, certain communications may have no keywords at
all. In that case, this process would end after a single pass. For
yet another embodiment, under some circumstances, the process may
ignore certain keywords. Certain references are not altered in the
communication. For example, references that call static images,
images that do not communicate information to the user and do not
have embedded references, may be of no interest. For example, if
the keyword calls a large passive figure with multiple components,
the process may ignore the entire figure, by tagging figure related
communications, and exit out of this process even if keywords
remain. By altering only those references that are of interest, the
process may be sped up. If a keyword was found, the process
continues to block 740.
[0071] At block 740, the process tests whether the keyword is an
attempt to access a cookie from the cookie database. If the keyword
is an attempt to access a cookie, the process continues to block
745. At block 745, the access attempt is changed to fetch the
cookie from the IIM's cookie database. Some examples of this
process are provided in FIG. 18. For one embodiment, the IIM's
cookie database may access the client browser's cookie database in
order to determine whether there are additional cookies on the
client browser. For one embodiment, the IIM can, with the user's
permission, copy cookies from the browser cookie database to the
IIM. This simplifies moving from direct access of a DS to accessing
a DS through the IIM. The process then continues to block 750.
[0072] If the keyword is not an attempt to access a cookie, the
process continues directly to block 750.
[0073] At block 750, the process tests whether the keyword is an
attempt to access the top frame or IIM frame. If the keyword is an
attempt to access the top frame or IIM frame, the process continues
to block 755. At block 755, the access attempt is changed to access
the top area of the destination server display area (DSDA). Some
examples of this process are provided in FIG. 17. The process then
continues to block 760.
[0074] If the keyword is not an attempt to access the top of IIM
frame, the process continues directly to block 760.
[0075] At block 760, the process tests whether the keyword is a
reference to the destination server. If the keyword is a reference
to the destination server, the process continues to block 765. At
block 765, the reference is changed to be fetched through the IIM.
Some examples of this process are provided in FIG. 16A-C. The
process then continues to block 770.
[0076] If the keyword is not a reference to the destination server,
the process continues directly to block 770.
[0077] At block 770, the process tests whether the keyword is an
attempt to access data from the top frame or IIM frame. If the
keyword is an attempt to access data from the top frame or IIM
frame, the process continues to block 775. At block 775, the access
attempt is changed to fetch data from the topmost frame of the
DSDA. Some examples of this process are provided in FIG. 19. The
process then returns to block 725, and parses to find the next
keyword.
[0078] For one embodiment, the above process may be triggered by a
user. For example, a user may select a link, activate a JavaScript
function, or otherwise initiate communication between the
destination server and the client. The same process may occur in
response to a cookie being sent or received, or a keyword being
found as described above with respect to FIG. 7.
[0079] FIG. 8 illustrates one embodiment of the user interface of
the independent intermediary mechanism. The user interface includes
a browser toolbar 805. For one embodiment, the IIM may configure
the browser such that the browser toolbar area 805 is not displayed
when the IIM is active. The display area 810 of the browser
includes the IIM toolbar 820, a hidden communications frame 815,
and the destination server display area 845.
[0080] The IIM toolbar 820 includes the known browser controls 825,
such as back, forward, refresh, stop, etc. Additional browser
controls 825 may be added. The toolbar 820 further includes an
address entry control 830, where a user can type a destination
server address in order to access the DS.
[0081] The IIM toolbar 820 may further include buttons, or other
selection mechanisms that permit a user to configure and use the
IIM. The buttons may include Home, selecting a user's preset
homepage, etc. The homepage is preset using the Set Home button
852. The buttons may further include the Mall button, giving
one-button access to shopping. The buttons may further include Tags
860, displaying a list of a user's bookmarks. Bookmarks are added
by selecting the Tag Address while visiting a web site, or by
selecting the Tag Address button 862, and typing the address of a
location to be bookmarked.
[0082] The buttons may further include Accounts 865, permitting
single-button log-on to a variety of accounts. These accounts are
added with the Add Account button 867, as will be described
below.
[0083] The buttons may also include a Transactions button 870, that
permits a user to review his or her transactions. This is
illustrated in the destination server display area 845 of FIG. 8.
The Profile button 875 permits the user to enter his or her
personal data. The Fill-Form button 880 permits the user to fill in
a form using the personal data from the user's profile or by using
information submitted previously using the same form. If a form is
displayed on the destination server display area 845, and the user
selects the fill-form button 880, the form is automatically filled
in with the user's information. The Clear Form button 882 permits a
user to remove the information filled into a form. This provides an
additional level of security to the user.
[0084] The Admin button 885 provides access to account
administration services. For one embodiment, the Admin button 885
is only available to those users who are authorized administrators.
For one embodiment, the Admin button 885 is only displayed if the
user is authorized to access account administration services.
[0085] The toolbar 820 further includes a Bye button 890, which
logs off the user from the IIM. The toolbar 820 illustrated is
exemplary. The content and organization of the buttons on the
toolbar 820 may be changed without changing the invention.
[0086] FIG. 9 illustrates another embodiment of the user interface
of the independent intermediary mechanism. As can be seen, the user
interface may be flexibly implemented. Certain features may be
provided by one interface and not provided by another. Furthermore,
the look and feel of the user interface may be altered. The user
may, for example, access all of the IIM features through pull-down
menus, such as the pull-down menu 935, or radio buttons instead of
buttons. One skilled in the art understands other types of user
interface changes that may be made without departing from the
broader spirit and scope of the invention as set forth in the
appended claims.
[0087] FIG. 10 is a flowchart of one embodiment of the form fill
functionality. At block 1010, a document with a form is displayed.
For one embodiment, this is a result of a user accessing a
destination server location that includes a form. This form may be
an order form, an information request form, or any other form that
may be encountered on the Web.
[0088] At block 1015, the user requests the form-fill function
through the IIM user interface. For one embodiment, the user
presses the form-fill button. For another embodiment, the form fill
may be automated. For yet another embodiment, the user can select
whether the form fill function is automatically engaged.
[0089] At block 1020, the process determines whether the form is in
the user's transaction database. The user's transaction database
has records of previously accessed and filled-in forms for the
particular user. The transaction database may maintain such records
for a limited time, or the user may delete transaction records.
Thus, merely because a user has been to a particular site
previously may not mean that the form is in the user's transaction
database. If the form is in the user's transaction database, the
process continues to block 1040, otherwise, the process continues
to block 1025.
[0090] At block 1025, the process determines whether the form is in
the form database. The form database is maintained by the IIM and
includes "known" forms. Such known forms have associations between
form control identifiers in the form and profile items. Thus, for
example, a form control identifier that is labeled "name" may have
a link to the "First Name Last Name" item in the user profile. If
the form is known, the process continues to block 1030. At block
1030, the form control identifiers in the form are filled in from
the user profile. The process then returns to block 1055.
[0091] If the form is not known, the process continues to block
1035. At block 1035, the form controls are identified, based on the
name of each control. Each control name is associated with entries
in the user profile. The process then continues to block 1030, and
the data is filled into the form from the user profile. For one
embodiment, block 1035 is skipped. This type of "guessing" may be
user enabled, or may be only attempted for forms that are similar
to known forms.
[0092] At block 1020, if the form was found in the user's
transaction database, the process continued to block 1040. At block
1040, the process tests whether any data in the user profile has
been changed since the transaction in the transaction database was
recorded. Transaction records are dated, as are changes to the user
profile. A user profile may be changed by the user, for example, to
change a credit card expiration date, number, or home address. If a
user profile change of a relevant field is dated after the
transaction record date, the process continues to block 1045,
otherwise, the process continues directly to block 1050.
[0093] At block 1045, the changed information is filled in from the
user profile. In this way, the user only had to update his or her
records once, in the profile, and that change is carried through
the IIM. For one embodiment, this step may be skipped. For another
embodiment, this step may be user enabled.
[0094] At block 1050, the remaining form control identifiers in the
form are filled with data from the transaction database. The
process then continues to block 1055.
[0095] At block 1055, the filled-in form is displayed to the user,
and the user is permitted to edit the data in the form. The user,
for example, may not wish to provide certain data to a destination
server. The user may chose to erase such data. Alternatively, the
form may request data that is not found in the user's profile. The
user may chose to fill in such data.
[0096] At block 1060, the user submits the form to the destination
server. For one embodiment, the IIM stores the information
submitted to the server in the user's transaction database. This is
illustrated in FIG. 13 below. At block 1065, the process ends. For
one embodiment, the user may optionally select whether to use the
user profile, transaction database, or both, and in what order, for
form fill functions.
[0097] FIG. 11 is a flowchart of one embodiment of the learning
process in the database. At block 1110, a privileged user connects
to the IIM. For one embodiment, this privileged user is an employee
of the group maintaining the IIM. For another embodiment, this
"user" is an artificial intelligence unit that is used to identify
forms, as will be described below. Such intelligent recognition
programs are known in the art.
[0098] At block 1120, the privileged user accesses a destination
server page with a form through the IIM. At block 1130, the IIM
displays a user interface for cataloguing the form.
[0099] At block 1140, the user maps each form control to an element
in the user profile object. The user profile is set up to contain a
large number of possible data elements. Each form control should
have a corresponding profile element. If no profile element is
found for a form control, that form control may be tagged as "form
specific." For one embodiment, multiple elements in the user
profile may be associated with a single form control, or vice
versa.
[0100] At block 1150, other information about the form is added.
This information may include such information as the address of the
form, whether the connection with the destination server that
serves the form is a secure connection, whether the form is of a
particular classification, etc.
[0101] At block 1160, the user submits the information to the
IIM.
[0102] At block 1170, the IIM updates the form identification and
form description in the form database to include the information
added by the user. For one embodiment, the updating is a periodic
batch updating. For one embodiment, a single central form database
is maintained. In that instance, the IIM's updating may include
sending the new form to other IIMs. Alternatively, each IIM may
maintain its own separate form database. For yet another
embodiment, an IIM may have a central form database, and a separate
internal form database. This may be useful, for example, for an IIM
implemented within a company which has the general form database
for pages accessed outside the company, and a separate internal
database for internal web page forms.
[0103] At block 1180, the process ends. Of course, the privileged
user may enter multiple entries, and may start the process again at
block 1120.
[0104] FIG. 12A is a flowchart of one embodiment of adding
accounts. At block 1210, the user connects to the IIM through a
client browser. At block 1220, the user accesses a destination
server through the IIM. For one embodiment, the user accesses the
account log-in page of the DS. This may be, for example, the
account log-in page of the user's bank, of a portal, or of any
other DS.
[0105] At block 1230, the user requests to add the account to the
user's account database. Each user may have an account database,
which includes a list of accounts the user can access with a single
click.
[0106] At block 1235, the process determines whether the user has
submitted login information to the account log-in page. If the user
has not submitted the information, the process continues to block
1240, and the user is prompted to complete the log-in process. For
one embodiment, if the account log-in process includes multiple
pages, the user may indicate the end of the log-in process by
pressing a certain key, or through other means. The process then
continues to block 1245. If the user has submitted all of the
log-in information, the process continues to block 1245
directly.
[0107] At block 1245, the account entry is added to the user's
account database. The account log-in information and data of
account entry creation are recorded. For one embodiment, further
information may be recorded. For yet another embodiment, only the
user's log-in procedure is recorded.
[0108] At block 1250, the account information is submitted to the
DS for login. At block 1255, the process ends.
[0109] FIG. 12B is a flowchart of one embodiment of accessing an
account through an auto-log-in feature. At block 1260, the user
connects to the IIM. At block 1265, the user accesses the account
auto-log-in feature using the IIM user interface. For one
embodiment, this is done by the user pushing the account
button.
[0110] At block 1270, the user selects an account to log into. For
one embodiment, the user may have multiple accounts. In that
instance, the IIM displays the accounts that the user has. For
another embodiment, if the user only has a single account, that
account is automatically selected when the user accesses the
auto-log-in feature.
[0111] At block 1275, the IIM retrieves login information from the
user's account database. As discussed above, the user's previous
account log-in is monitored and recorded. This information is
retrieved at block 1275.
[0112] At block 1280, the IIM sends the log-in information to the
appropriate destination server to log-in the user. The account
information includes the address of the DS. The IIM accesses the DS
as a client, and sends the user's information.
[0113] At block 1285, the IIM instruments the DS's response and
sends it to the user's browser for display. As discussed above, the
response is instrumented such that references of interest are
routed through the IIM. The user can now use the account, as usual.
At block 1290, the process ends.
[0114] FIG. 13 is a flowchart of one embodiment of the transaction
management functionality. At block 1310, the user connects to the
IIM.
[0115] At block 1320, the user transmits information in a form to
the destination server. For one embodiment, the user first accesses
a destination server page including a form through the IIM. This
form may be an order form, an e-mail form, or any other type of
form. The user then fills in the form and submits it to the DS. For
one embodiment, the user may use the form-fill method described
above to fill-in the form.
[0116] At block 1330, the process determines whether the user sent
the user's email address to the DS. The user may submit his or her
e-mail address so the DS can send responses directly to the user's
e-mail. For example, certain systems may send confirmation e-mails
or alert notices to the user via e-mail. If the user submitted his
or her e-mail address, the process continues to block 1340.
Otherwise, the process continues directly to block 1350.
[0117] At block 1340, the e-mail address submitted to the DS is
altered. Specifically, the e-mail address is bifurcated, generated
two e-mails. The first email goes to the user's e-mail address, as
entered. The second e-mail goes to the IIM. The second e-mail
includes in its address the IIM and the transaction tag that
identifies the transaction number to which the e-mail belongs. This
allows the IIM to handle the e-mail. The process then returns to
block 1350.
[0118] At block 1350, the IIM records a transaction in the user's
transaction database and associates the submitted information with
the transaction. The transaction, for one embodiment, has a
transaction number.
[0119] At block 1360, the IIM determines whether there is a
response from the DS. If there is a response, the process continues
to block 1370. Otherwise, the process continues directly to block
1380.
[0120] At block 1370, the IIM records the response from the DS in
the user's transaction database. For one embodiment, the
destination server may respond to the user. This response is
associated with the transaction record. In this way, the user may
review the transaction record, including the response.
[0121] At block 1380, further information is recorded about the
transaction. For one embodiment, this information may include the
date and time of the transaction, and other information.
[0122] At block 1390, any notes, data, or e-mails received with the
transaction tag are attached to the transaction. This may occur at
any time, while the transaction is being recorded, or after that.
The user may attach any data to the transaction, and the IIM may
automatically attach any e-mails received with the transaction
tag.
[0123] At block 1395, the process ends.
[0124] FIG. 14 illustrates one embodiment of the listing of
transactions. The transaction list 1410 may be sorted by date,
using a menu 1425. The transactions may also be sorted by type
1435. For one embodiment, alternative methods of searching
transactions may also be implemented. For example, a user may
search the transaction records for purchases from a certain
destination server.
[0125] Each transaction record may include one or more of the
following: date 1420, transaction type 1430, and description 1440
of the transaction. The record may further include the place 1450,
the location from where the transaction was recorded. The user may
add and edit additional notes 1460. Furthermore, the user may also
add attachments 1415 to the transaction record. For example, the
user may attach e-mails, documents, video, or other types of data.
For one embodiment, e-mails may be redirected through the IIM and
automatically attached to the transaction.
[0126] The vendor response 1470 is also recorded. The information
the user provided 1480 during the transaction is also included in
the transaction record. The transaction may further include the
information whether the transaction belongs to one of the accounts
1490 in the user's account database. The user is permitted to
delete selected transaction records using a delete button 1465.
[0127] FIG. 15A is a flowchart of one embodiment of selection of a
home page. The user connects to the IIM at block 1505.
[0128] At block 1510, the user accesses a destination server page
through the IIM. At block 1515, the process determines which option
the user is selecting.
[0129] If the user is selecting the add bookmark option, the
process continues to block 1525. At block 1525, the address of the
page is added to the user's bookmark database. This database is
accessible to the user, to permit the user to access various web
sites without typing the address of the site. The process then
continues to block 1530, and ends.
[0130] If the user selected the set home page option at block 1515,
the address of the page is set as the user's homepage. The user's
homepage is called up when the user initially connects to the IIM.
For one embodiment, the homepage is preset. For another embodiment,
the user may not alter the homepage, and the homepage is
customizable but includes advertising. The process then continues
to block 1530, and ends.
[0131] FIG. 15B is a flowchart of one embodiment of using the
bookmark functionality. At block 1535, the user connects to the
IIM. At block 1540, the user requests access to the user's
bookmarks through the IIM user interface. For one embodiment, the
user requests the bookmarks by pressing the "Tags" button on the
user interface.
[0132] At block 1545, the IIM generates a bookmark list from the
user's bookmark database, and sends the list to the client browser
to display. For one embodiment, the bookmark list is displayed in
the destination server display area. For another embodiment, the
bookmark list is displayed in a separate window, or a separate
frame.
[0133] At block 1550, the user selects a bookmark to access a
destination server page.
[0134] At block 1555, the IIM fetches the page address
corresponding to the selected bookmark from the bookmark database.
The bookmark database includes the actual address of the
bookmark.
[0135] At block 1560, the destination server page is fetched by the
IIM. The data from the destination server is instrumented and is
sent to the client browser for display. In this way, the user can
access bookmarks stored in the IIM's bookmark database. The process
then continues to block 1565, and ends.
[0136] FIG. 15C is a flowchart of one embodiment of using the
history functionality. At block 1570, the user connects to the
IIM.
[0137] At block 1575, the user requests access to the history list
through the IIM user interface. The history list includes the sites
the user previously visited. For one embodiment, the history list
is maintained for only a period of time, such as thirty days. For
another embodiment, the history list is maintained indefinitely,
and may be purged by the user.
[0138] At block 1580, the IIM generates a history list from the
user's history database, and sends the history list to the client
browser for display. For one embodiment, the history list is
displayed in the destination server display area. For another
embodiment, the history list is displayed in a separate window, or
a separate frame
[0139] At block 1582, the user selects a list entry to access the
destination server page. At block 1585, the IIM fetches the page
address from the history database. The page address is referenced
through the IIM.
[0140] At block 1590, the IIM fetches the destination server page,
instruments the communication, and sends the data to the client
browser for display. At block 1595, the process ends. In this way,
the IIM permits a user to access a variety of services through the
IIM.
[0141] FIGS. 16A-C show sample alterations of references from the
destination server by the IIM. FIGS. 16A-C illustrate changes to
HTML, HTTP protocol, JavaScript, and Java. For one embodiment, this
technique may be expanded to new languages and other types of
interfaces. The data that is normally communicated directly between
a Destination Server (DS) and client browser is altered by the IIM,
as shown by FIGS. 16A-C. For one embodiment, some data may be
transmitted directly between the DS and the client browser, without
passing through the IIM.
[0142] For one embodiment, the IIM performs a subset of the message
modifications required for redirection and downloads the client
component to the client's browser, which performs the remaining
subset of message modifications on the client machine. Together
these two subsets of message modifications provide a complete
solution for using an independent intermediary mechanism between a
client and a server.
[0143] The modification of HTTP communication messages for
redirection occurs on both the IIM and the client browser using the
client component. The points at which the message modifications
occur are called "HTTP control points".
[0144] FIGS. 16A-C illustrate examples of HTTP control points that
occur on the client browser and the IIM. For HTTP message
documents, description of modification code covers the three
programming languages that are most widely used today for HTTP
communication: HTML, JavaScript and Java. For another embodiment,
the IIM utility may be broadened to include HTTP control points in
other programming languages used for HTTP message documents. For
one embodiment, the protocol modified in the messages is defined by
the HTTP specification standard. One skilled in the art would
understand how to expand the technique described to different
programming languages or message protocols.
[0145] FIG. 17 is a table illustrating examples of making the IIM
user interface frame persistent. The IIM prevents DS's from
overwriting the user interface of the IIM. This permits the user to
access the IIM regardless of what DS he or she is accessing.
[0146] FIG. 18 is a table illustrating examples of accessing
cookies from the IIM. Generally, the destination server and
destination server data on the client system access the cookie
cache on the client's computer system. The IIM modifies the access
mechanisms to access cookies from the IIMs cookie database.
[0147] FIG. 19 is a table illustrating examples of preserving top
frame or IIM frame integrity for DS. Objects are often hung from
the top frame of the client browser. The IIM changes the references
to the top frame to create or access these objects to references to
the top frame of DSDA. In this way, the objects are appropriately
handled.
[0148] FIGS. 16-19 list some sample alterations resulting from the
code instrumenting described above. Alternative methods of altering
the code may be used. One skilled in the art knows how to implement
different changes.
[0149] In the foregoing specification, the invention has been
described with reference to specific exemplary embodiments thereof.
It will, however, be evident that various modifications and changes
may be made thereto without departing from the broader spirit and
scope of the invention as set forth in the appended claims. The
specification and drawings are, accordingly, to be regarded in an
illustrative rather than a restrictive sense.
