BACKGROUND OF THE INVENTION

00031. Field of the Invention

0004The present invention generally relates to the display of data available over a network. More particularly, the invention provides for the integrated display of at least one item of public data and at least one item of private data.

00052. Background of the Prior Art

0006The Internet, which comprises a vast array of computer networks distributed throughout the world, provides online service subscribers with an almost limitless supply of information. Some of this information is public, and some is private. As used herein, public information refers to data, applications, and other such information which is equally accessible by all or substantially all users of a public network. Private information refers to information which is accessible by less than substantially all users, namely by one or more authorized parties, and usually requires a user to verify his or her identity in some way (e.g., by supplying a user name and password). Public information includes, for example, the weather in Tokyo as offered by a weather information website, the price of airfares from New York to London as provided by a travel related site, and other such information. Private information includes, for example, bank account records, 401k account information, and credit card balance information. Such information is typically accessible via an appropriate financial institution, bank and/or credit card website.

0007Information on the Internet can also be classified as either internal or external. Internal information includes that information which is provided by a company, through a website (or other network protocol), that is proprietary to that company. External information is information that is accessible from websites other than the website of the particular company. For example, if a user visits the site of her bank and accesses various account information, she is accessing internal information. If she then wishes to check the Dow Jones Industrial Average Stock Index on a page that is not a part of the bank's website, she will be accessing external information. Any one company may include multiple internal content providers. For example, one provider within the company may provide retirement account information, another may provide mutual fund account information, and a third may provide credit card balances and a method for paying balances on the Internet.

0008Known systems for acquiring and displaying information are unsatisfactory in a number of respects. For example, prior art systems do not sufficiently allow an individual to access and view both public and private data simultaneously. That is, viewing combinations of public and private data usually includes jumping between two or more websites, viewing only one at a time, or using two separate digital viewing devices, such as two computer screens. While some systems integrate public and private data on one screen, these systems are limited. For example, U.S. Pat. No. 5,319,542 describes a system for ordering items from an electronic catalogue. The system of the '542 Patent does allow a user to simultaneously view items in a catalogue (public data) and an order form including purchase information (private data). Moreover, the system remains static until updated by the user and is not interactively linked to the utilities or interactive services of the catalogue business or other entities, such as business partners of the catalogue business. In other words, the system usually includes the user inputting all of the private information that she then views in her order form. Thus, private information from the company's data stores is not made automatically available to the user.

0009Furthermore, with the proliferation of Internet use, systems have been described which track and process user preferences so that Internet service providers (ISPs) can customize user experiences or target marketing efforts to users with specified preferences. An example of target marketing is disclosed in U.S. Pat. No. 6,157,946, the target marketing contents of which are hereby incorporated by reference. Additionally, U.S. Pat. Nos. 5,848,396 and 5,991,735 owned by Freedom of Information, Inc. and Be Free, Inc., respectively, generally disclose a computer network for providing targeting of appropriate audiences based on psychographic or behavioral profiles of the end users, and are herein incorporated by reference. To track user preferences, some prior art systems create user profiles based on direct input by the user or on an automatic analysis of the websites accessed by the user Known systems, however, do not typically automatically track both private and public data, accessed by a user, to create a user profile. Some existing systems create user profiles based on a user's consumption of public electronic data, while other existing systems create profiles based on private data manually input by the user. A system is needed that combines the two types of data to create profiles while automatically adding pre-existing data from proprietary databases. Additionally, prior art systems do not allow a company or other entity to combine proprietary data, from one or more internal content providers, and user preferences of public data as variable input to business rules to create unique, individually tailored services containing both public and private elements.

0010Thus, a need exists for systems that allow a user to simultaneously access and view public and private data on the same network interface device or system, such as a web page, wireless screen, other digital viewing device or printer. There is also a need for a system that automatically tracks user preferences, based on the public and private data accessed by the user and on data from one or more internal content provider data stores. Finally, a need exists for a system that allows a company to use automatically derived user preference data to personalize the user's experience on the company's website.

BRIEF SUMMARY OF THE INVENTION

0011The system facilitates the simultaneous access and viewing of public and private data by integrating the two forms of data. Public and private data may be accessed from at least one internal content provider, at least one external content providers or a combination of both. In other embodiments, the system allows internal content providers to create user profiles responsive to proprietary user information from their own databases and automatically-generated information regarding user preferences of information accessed from the a network. Internal content providers can then use these profiles to personalize, for example, the experiences of the customers who use their website, and/or to specifically target marketing materials to its customers.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

0019A system in accordance with various aspects of the present invention facilitates simultaneously accessing and viewing public and private data from at least one content provider. In this regard, the description that follows sets forth various exemplary embodiments of the invention only, and is not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the following description is intended to provide convenient illustrations for implementing different embodiments of the invention. As will become apparent, various changes may be made in the function and arrangement of the elements described in these embodiments without departing from the spirit and scope of the invention. For example, changes may be made in the design and arrangement of the elements described in the preferred embodiments without departing from the scope of the invention as set forth in the appended claims.

0020The system may include a host server or other computing systems including a processor for processing digital data, a memory coupled to said processor for storing digital data, an application program stored in said memory and accessible by said processor for directing processing of digital data by said processor, a display coupled to the processor and memory for displaying information derived from digital data processed by said processor and a plurality of databases, said databases including client data, merchant data, financial institution data and/or like data that could be used in association with the present invention. As those skilled in the art will appreciate, user computer will typically include an operating system (e.g., Windows NT, 95/98/2000, Linux, Solaris, etc.) as well as various conventional support software and drivers typically associated with computers. Alternatively, user system may be a personal digital assistant (“PDA”), internet enabled wireless phone or the like. User system can be in a home or business environment with access to a network. In an exemplary embodiment, access is through the Internet, through a commercially-available web-browser software package.

0021The host computer may provide a suitable website or other Internet-based graphical user interface which is accessible by user systems. In one embodiment, the Internet Information Server, Microsoft Transaction Server, and Microsoft SQL Server, are used in conjunction with the Microsoft operating system, Microsoft NT web server software, a Microsoft SQL database system, and a Microsoft Commerce Server. Additionally, components such as Oracle, MySQL, Intervase™, etc., may be used to provide database management system. The term “webpage” as it is used herein is not meant to limit the type of documents and applications that might be used to interact with the user. For example, a typical website might include, in addition to standard HTML documents, various forms, Java applets, Javascript, active server pages (ASP), common gateway interface scripts (CGI), extensible markup language (XML), dynamic HTML, cascading style sheets (CSS), helper applications, plug-ins, and the like.

0022The present invention may be described herein in terms of functional block components, screen shots, optional selections and various processing steps. It should be appreciated that such functional blocks may be realized by any number of hardware and/or software components configured to perform the specified functions For example, the present invention may employ various integrated circuit components, e.g., memory elements, processing elements, logic elements, look-up tables, and the like, which may carry out a variety of functions under the control of one or more microprocessors or other control devices. Similarly, the software elements of the present invention may be implemented with any programming or scripting language such as C, C++, Java, COBOL, PERL, with the various algorithms being implemented with any combination of data structures, objects, processes, routines or other programming elements. Further, it should be noted that the present invention may employ any number of conventional techniques for data transmission, signaling, data processing, network control, and the like.

0023It will be appreciated that many applications of the present invention could be formulated. One skilled in the art will appreciate that the network may include any system for exchanging data or transacting business, such as the Internet, an intranet, an extranet, WAN, LAN, VPN (virtual private network), satellite communications, and/or the like. It is noted that the network may be implemented as other types of networks, such as an interactive television (ITV) network. The users may interact with the system via any input device such as a keyboard, mouse, kiosk, personal digital assistant, handheld computer, cellular phone and/or the like. Similarly, the invention could be used in conjunction with any type of personal computer, network computer, workstation, minicomputer, mainframe, or the like running any operating system such as any version of Windows, Windows NT, Windows 2000, Windows 98, Windows 95, MacOS, OS/2, BeOS, Linux, UNIX Solaris or the like. Moreover, although the invention is frequently described herein as being implemented with TCP/IP communications protocols, it will be readily understood that the invention could also be implemented using IPX, Appletalk, IP-6, NetBIOS, OSI or any number of existing or future protocols. Moreover, the system contemplates the use, sale or distribution of any goods, services or information over any network having similar functionality described herein.

0024The computing units may be connected with each other via a data communication network. The network may be a public network and assumed to be insecure and open to eavesdroppers. In the illustrated implementation, the network may be embodied as the internet. In this context, the computers may or may not be connected to the internet at all times. For instance, the customer computer may employ a modem to occasionally connect to the internet, whereas the bank computing center might maintain a permanent connection to the internet. Specific information related to the protocols, standards, and application software utilized in connection with the Internet may not be discussed herein. For further information regarding such details, see, for example, DILIP NAIK, INTERNET STANDARDS AND PROTOCOLS (1998); JAVA 2 COMPLETE, various authors, (Sybex 1999); DEBORAH RAY AND ERIC RAY, MASTERING HTML 4.0 (1997). LOSHIN, TCP/IP CLEARLY EXPLAINTEDEXPLAINED (1997). All of these texts are hereby incorporated by reference.

0025The systems may be suitably coupled to network via data links. A variety of conventional communications media and protocols may be used for data links. Such as, for example, a connection to an Internet Service Provider (ISP) over the local loop as is typically used in connection with standard modem communication, cable modem, Dish networks, ISDN, VPN, Digital Subscriber Line (DSL), or various wireless communication methods. Merchant system might also reside within a local area network (LAN) which interfaces to network via a leased line (T1, D3, etc.). Such communication methods are well known in the art, and are covered in a variety of standard texts. See, e.g., GILBERT HELD, UNDERSTANDING DATA COMMUNICATIONS (1996), hereby incorporated by reference.

0026<figref idref="DRAWINGS">FIG. 1</figref> is a conceptual block diagram providing an overview of an exemplary system in accordance with one embodiment of the present invention. As shown, the system can be partitioned as a four-tier structure, including a back-end systems tier <b>102</b>, an application server tier <b>104</b>, a web server tier <b>106</b>, and a client tier <b>108</b>. The backend systems tier <b>102</b> suitably comprises, for example, one or more external content providers <b>116</b>, one or more internal content providers <b>120</b>, and a processor <b>118</b> coupled to the content providers <b>116</b>. Each external content provider <b>116</b> and each internal content provider <b>120</b> suitably includes, for example, one or more data storage devices configured to store public and/or private information as applicable.

0027The data storage devices for the backend systems may be any type of data storage device, such as relational, hierarchical, object-oriented, and/or the like. Common data storage products that may be used to implement the databases include DB2 by IBM (White Plains, N.Y.), any of the database products available from Oracle Corporation (Redwood Shores, Calif.), Microsoft Access by Microsoft Corporation (Redmond, Wash.), or any other database product. Database may be organized in any suitable manner, including as data tables or lookup tables. Association of certain data may be accomplished through any data association technique known and practiced in the art. For example, the association may be accomplished either manually or automatically. Automatic association techniques may include, for example, a database search, a database merge, GREP, AGREP, SQL, and/or the like. The association step may be accomplished by a database merge function, for example, using a “key field” in each of the manufacturer and retailer data tables. A “key field” partitions the database according to the high-level class of objects defined by the key field. For example, a certain class may be designated as a key field in both the first data table and the second data table, and the two data tables may then be merged on the basis of the class data in the key field. In this embodiment, the data corresponding to the key field in each of the merged data tables is preferably the same. However, data tables having similar, though not identical, data in the key fields may also be merged by using AGREP, for example.

0028Application server <b>110</b> is any hardware and/or software suitably configured to process messages from and to web server tier <b>106</b> and back-end systems tier <b>102</b>. More particularly, in an exemplary embodiment, application server tier <b>104</b> suitably includes an application server <b>110</b> coupled to a personal preferences data store <b>122</b> and a personal profile data store <b>124</b> (e.g., a lightweight directory access protocol database, or “LDAP”). In the illustrated embodiment, each external content provider <b>116</b> from the backend systems tier <b>102</b> is suitably connected to the application server via processor <b>118</b>, and each internal content provider <b>120</b> is suitably connected to application server <b>110</b>. Personal preferences data store <b>122</b> and personal profile data store <b>124</b> are also suitably coupled to application server <b>110</b>.

0029Referring now to <figref idref="DRAWINGS">FIGS. 1 and 2</figref>, an exemplary display <b>202</b>, produced by the system of <figref idref="DRAWINGS">FIG. 1</figref> (e.g., a web page displayed on a computer monitor), includes integrated data <b>204</b> from various internal content providers <b>120</b> and external content providers <b>116</b> (<figref idref="DRAWINGS">FIG. 1</figref>). In one embodiment of the present invention, integrated data <b>204</b> may comprise data from one or more internal content providers <b>120</b> and data from one or more external content providers <b>116</b>. Alternatively, integrated data <b>204</b> may derive only from one or more internal content providers <b>120</b>, with no integrated data <b>204</b> from any external content provider <b>116</b>. Integrated data <b>204</b> comprises at least one item of public data and at least one item of private data. In one embodiment, integrated data <b>204</b> is interactively or automatically updated in accordance with any changes, modifications, or updates that might occur at the respective internal or external content providers <b>120</b> or <b>116</b>. Interactive updating refers to pulling data from data stores by a user system <b>126</b>, such as when user system <b>126</b> requests a credit card balance. Automatic updating refers to pushing data out of a data store to user system <b>126</b> without the user system <b>126</b> requesting it, for example if user system <b>126</b> is automatically provided with the Dow Jones Industrial Average.

0030In one embodiment of the present invention, one or more internal content providers <b>120</b> include a proprietary data store of an organization (e.g., a company, educational institution, financial institution, or the like). Typically, internal content providers <b>120</b> are selected from a suite of services offered by one of internal content providers <b>120</b>. For example, a user may choose to display brokerage services, card balances, and 401K account information from a list of available information made accessible by a financial institution corresponding to internal content provider <b>120</b>. In one embodiment of the present invention, each site aggregates network users <b>126</b> to create what is referred to as a web portal Portals may be configured to provide access to content and functionality centered around common interests or may differ in their focus and objectives. Thus, the system according to the present invention suitably integrates public and private data into integrated data <b>204</b>, which is displayed on user system <b>126</b>, for example a single customizable page on one digital display <b>202</b>, and which reflects a network user's preferences.

0031Having thus given an overview of the present invention, a detailed description of its various components will now be provided.

0032Application Server

0033As mentioned briefly above, application server <b>110</b> is any hardware and/or software suitably configured to process messages from and to web server tier <b>106</b> and back-end systems tier <b>102</b>. In accordance with one embodiment of the present invention, application server <b>110</b> uses Java or any type of general purpose programming language that supports the creation of dynamic web page content. In accordance with one embodiment of the present invention, general application server <b>110</b> utilizes Java Server Pages (“JSPs”) and JavaBeans to populate web forms with local databases, client/server databases, and legacy databases to access multiple server resources. JSPs enable developers to effectively separate HTML coding from the business logic in web pages. Furthermore, various companies, e.g. IBM, have developed extensions to the JSP specification that include JSP tags, which are HTML-like and can be used to access databases, and reusable Java components, such as servlets and JavaBeans. For further information regarding such details, see, for example, NICHOLAS KASSEM AND THE ENTERPRISE TEAM, DESIGNING ENTERPRISE APPLICATIONS WITH THE JAVA 2 PLATFORM, ENTERPRISE EDITION (2000), which is hereby incorporated by reference. The web forms, including, infer alia, Java applets, are exposed to the user's browser and are then transferred through the various JSPs to a collection of Java Servlets. Java Servlets are then transferred to an MQ Series connector, a TCP/IP connector, or a JDBC (Java Database Connector). Data then travels from the MQ Series connector to a transaction server and then to a legacy application and, subsequently, legacy databases. Other data travels from the TCP/IP connector to TCP/IP sockets and then to client/server applications and, subsequently, client/server databases. Still other data travels from the JDBC to local databases. In accordance with one aspect of the present invention, Java components are suitably created to provide HTML authors with component names and attributes, wherein the appropriate database administrators provide HTML authors with the name of the database to be accessed along with table information.

0034An additional feature of application server tier <b>104</b>, according to one embodiment of the present invention, is the internal “smart-caching” of data. Smart-caching allows rules to be associated with data elements, defining when the distributed system must expend the additional overhead to make a new call to the system of record, rather than using a previously cached set of information. For example, in the context of a credit card provider with a rewards system, if it is known that updates of loyalty rewards points are only done monthly, when an additional request for rewards data is made within the month, the cached data is returned, thus improving performance and system load.

0035Referring to <figref idref="DRAWINGS">FIG. 1</figref>, in accordance with one embodiment of the present invention, personal profile data store <b>124</b> is connected to application server <b>110</b> and is configured to personalize the experience of network user systems <b>126</b>. Specifically, user system <b>126</b> communicates with personal profile data store <b>124</b> by making a request over network <b>114</b>. Such requests are referred to as “binding requests.” Binding requests may include, for example, the user's data store current version, the method of authentication, and any credentials for authentication. Personal profile data store <b>124</b> then receives the binding request and accesses backend functions for a return reply. In one embodiment, the system stores user system's <b>126</b> profile in a personal profile data store <b>124</b> and uses the information to dynamically create a customized page.

0036In one embodiment of the invention, after the application is loaded, a servlet continues to wait for additional user system <b>126</b> requests. Servlet aliases may be used to provide multiple instances of a servlet for each request. The functionality of a servlet includes, for example creating and returning an entire HTML page containing dynamic content based on the nature of user system's <b>126</b> request; creating a portion of an HTML page or HTML fragment that can be embedded in an existing HTML page; communicating with other servlets; handling connections with multiple user systems <b>126</b>; filtering data for special processing such as image conversion; and providing customized processing to any of web server's <b>112</b> standard routines.

0037Any convenient set of hardware and/or software components may be configured in order to provide the functionality of application server <b>110</b>, personal preferences data store <b>122</b>, and personal profile data store <b>124</b>. For example, in one embodiment, a Sun Enterprise 450 server can be used, equipped with one to four Ultra-SPARC-II processors, 128 MB to 4 GB total memory capacity, Solaris 2.6 operating system, IBM WebSphere application server 3.5.

0038Web Server

0039Web server <b>112</b> is any hardware and/or software suitably configured to provide a web service to network user systems <b>126</b> and/or to interface with network <b>114</b> and application server <b>110</b>. In the illustrated embodiment, application server <b>110</b> is connected, via a suitable data connection <b>130</b>, to web server <b>112</b> within the web server tier <b>106</b>. In accordance with a preferred embodiment of the present invention, web server <b>112</b> uses servlets to provide a framework for creating applications that implement a request/response paradigm. As mentioned above, in an exemplary embodiment, a servlet is a server side component, written in Java, that dynamically extends the functionality of a server. Servlets are used to extend a web server's <b>112</b> capabilities by creating a framework for providing request and response services over the network. In one embodiment of the present invention, network user system <b>126</b> sends a request to web server <b>112</b> and the server <b>112</b> sends the request information to a Java servlet. The servlet can be loaded automatically when the application is loaded or can be loaded the first time a user system <b>126</b> requests its services. The servlet dynamically builds a response according to the user system's <b>126</b> request by utilizing other server <b>112</b> resources, including databases and Java-enabled applications. The servlet then passes a response to the web server <b>112</b>, which sends the response back to the user system <b>126</b>.

0040A variety of hardware and/or software components may be configured to implement the functionality of web server <b>112</b>. For example, in one embodiment, a Sun Enterprise <b>450</b> server can be used, equipped with one to four Ultra-SPARC-II processors, 128 MB to 4 GB total memory capacity, Solaris 2.6 operating system, Netscape Enterprise Web Server.

0041Network and User Systems

0042According to one embodiment of the present invention, web server <b>112</b> is connected to network <b>114</b> via a web/network connection <b>128</b>. Network <b>114</b>, in turn, is connected to one or more network user systems <b>126</b>. In one embodiment of the invention, network user systems <b>126</b> access the network <b>114</b> via the Internet or other global communications system. Alternatively, users may choose to access network <b>114</b> via remote access. New, unregistered or opted-out network user systems <b>126</b> may be provided a default content page which user systems <b>126</b> may then customize according to their preferences, which may also be recorded in personal preferences data store <b>122</b>. According to one embodiment, user systems <b>126</b> may customize multiple pages for viewing, including labeling and arranging the order of presentation. Technical and design standards may be communicated to user systems <b>126</b> to facilitate customization efforts.

0043<figref idref="DRAWINGS">FIG. 6</figref> is an exemplary screen shot of a personal web site created according to one embodiment of the present invention. This screen shot includes integrated data <b>204</b> with elements of public data and private data. Public data on the screen shot includes data under the “MY CARDS” heading, offering more information on card membership rewards and on applying for another card, and data under the “MY FINANCE” heading, showing market index graphs. Private data on the screen shot in <figref idref="DRAWINGS">FIG. 6</figref> includes data under the “MY ACCOUNTS” heading, including current balances, recent payments and membership rewards points available. This screen shot is for exemplary purposes only, and it will be understood by those skilled in the art that any number of combinations of public and private data may be accessed and viewed on a user system <b>126</b> according to various embodiments of the present invention.

0044In accordance with one embodiment of the present invention, security for users can be created through use of a 2-firewall infrastructure. More particularly, web/network connection <b>128</b> may include an Internet firewall, and application/web connection <b>130</b> may include an intranet firewall. Thus, connections initiated by network user systems <b>126</b> are protected by an Internet firewall between network <b>114</b> and web server <b>112</b> and by an intranet firewall between web server <b>112</b> and application server <b>110</b> Network user systems <b>126</b> suitably link to network <b>114</b> through a provider web server <b>112</b> with authentication between web server <b>112</b> and application server <b>110</b>. Backend systems tier <b>102</b> of enterprise information systems, provider business partners, and external services is suitably connected and protected by the Intranet firewall.

0045Exemplary Process

0046<figref idref="DRAWINGS">FIG. 3</figref> is a combination flow-chart/architectural diagram depicting an exemplary system for integrating data from various sources to form a web page on a digital display as shown in <figref idref="DRAWINGS">FIG. 2</figref>. In one embodiment of the present invention, this integration of data is accomplished by application server <b>110</b>, personal profile data store <b>124</b> and personal preferences data store <b>122</b> (see <figref idref="DRAWINGS">FIG. 1</figref>). The combination of application server <b>110</b>, personal profile data store <b>124</b> and personal preferences data store <b>122</b> is referred to as an application server system <b>334</b> in <figref idref="DRAWINGS">FIG. 3</figref>. (In <figref idref="DRAWINGS">FIG. 3</figref>, web server tier <b>106</b> is not depicted in order to simplify the diagram.)

0047In accordance with one embodiment of the present invention, a network user begins the process by entering registration/authentication data <b>318</b> in response to a request from application server <b>110</b>, the results of which are suitably stored in a personal profile utility. A personal profile utility may include a personal profile data store <b>124</b> and/or a personal preferences data store and/or any other suitable means for storing and accessing personal profile data. After entering this data, and thus registering for the first time, simple authentication may be requested, including, for example, ensuring that user system <b>126</b> provides a password to the personal profile data store <b>124</b>. After providing a password, user system <b>126</b> is allowed access to web server <b>112</b> on the provider's site (<figref idref="DRAWINGS">FIG. 1</figref>). In another embodiment, a certificate-based authentication may be used, wherein clients send certificates to personal profile data store <b>124</b> and the certificate identifies the data store client (i.e., user system <b>126</b>). In one embodiment of the present invention, all points of access into the system are protected through suitable firewalls. Similarly, the system of the present invention may also provide a login-blocking capability after unsuccessful login attempts. In yet another embodiment, other authentication and security mechanisms could be added to the system. For example, one or more of three levels of security could be implemented. These levels might be based on something the user knows, such as a password, something the user has, such as a smart card, and/or something the user “is,” such as a biometric fingerprint or retina scan. It will be understood that one, all or any combination of these three levels of security might be employed and that any other reliable technology for providing security to network user systems <b>126</b> may be used. For example, a combination of different levels of security might involve a card with a magnetic strip and a personal identification number, such as is used with aan ATM card.

0048In one embodiment of the present invention, confirmation of network user system <b>126</b> defines an identification code (“user ID”), which is then forwarded to user system <b>126</b> once registration is complete. Repeat network user systems <b>126</b> may be automatically recognized and served with the appropriate customized web page, even if they do not log in, e.g., through the use of cookies or similar technology. User systems <b>126</b> may also log in via remote access recognition. After login, user systems <b>126</b> may modify profile data such as user ID or password and account information. User systems <b>126</b> may retrieve their preferences or set their remote access code (“RAC”) to retrieve preferences remotely. In one embodiment, after registering for services offered by internal content provider <b>120</b>, network user system <b>126</b> is presented with a welcome page for system registration <b>318</b> and acceptance of terms and conditions. User systems <b>126</b> complete registration by providing information for the personal profile data store <b>124</b> and may select a RAC. Accessibility to any given service is restricted to user systems <b>126</b> with verified registrations. In one exemplary embodiment, registrations are verified against account records before data is shown. All points of entry into the system may be protected through at least one firewall. In one aspect of the invention, personal data is stored in a trusted domain of the web complex, with all confidential data encrypted before being transmitted over open networks.

0049Internal <b>120</b> and external <b>116</b> content providers may use information from personal profile data store <b>124</b> for many purposes. For example, information may be used for directing marketing efforts towards specific user systems <b>126</b>. To accomplish that end, user information may be retrieved from personal profile data store <b>124</b> and special promotional messages, offers and any other suitable marketing materials are presented to user systems <b>126</b>, based on that information. Similarly, internal <b>120</b> and external <b>116</b> content providers may customize the information they provide to network user systems <b>126</b>, based on user profile information. This customization is accomplished through personalization rules tied to content requests by the user systems <b>126</b>. For example, a holder of a particular credit card may be shown special events planned for holders of that card during a trip that the card holder has planned for a given city.

0050Referring again to <figref idref="DRAWINGS">FIG. 3</figref>, when a network user inputs registration or authentication data <b>318</b>, application server <b>110</b> suitably allows user system <b>126</b> to access both transactional assets <b>302</b> and content assets <b>304</b>. Transactional assets <b>302</b> comprise both company transactions <b>306</b> and business partner transactions <b>308</b>. Company transactions <b>306</b> are transactions provided by internal content provider <b>120</b>. Examples of company transactions <b>306</b> may include transactions provided by a credit card company, such as checking a credit card bill, 401K plan balance or brokerage account on line. Business partner transactions <b>308</b> are similar transactions provided by external content providers <b>116</b>, which are business partners of internal content provider <b>120</b>. Examples may include buying airline tickets or stocks on line. Content assets <b>304</b> comprise company content <b>310</b> and business partner content <b>312</b>. Company content <b>310</b> is provided by internal content provider <b>120</b> and may include investment advice or savings advice from a credit card company. Business partner content <b>312</b> is provided by external content provider <b>116</b> and may include news items from Reuters news service or weather reports from weather.com.

0051In accordance with one embodiment of the present invention, transactional assets <b>302</b> pass through a transactional aggregation utility <b>314</b>, which aggregates transactional assets <b>302</b>. Application server <b>110</b> may then send aggregated transactional assets <b>302</b> to either personal profile data store <b>124</b>, a security services utility <b>328</b> or a content management utility <b>330</b>. Also in accordance with one embodiment, content assets <b>304</b> may pass through a content aggregation utility <b>316</b>. Aggregated content assets <b>304</b> are then sent to content management utility <b>330</b>.

0052In accordance with one embodiment of the present invention, asset aggregation is achieved via aggregation utilities <b>314</b>, <b>316</b>, based upon the type of asset to be integrated. External, business partner content <b>312</b>, for example, may be aggregated by content aggregation utility <b>316</b>, which may be a content aggregation tool such as WebMethods or any other suitable content aggregation tool. Transactional assets <b>302</b>, on the other hand, may be aggregated by various methods, those methods being executed by an application server such as WebSphere or any other suitable server. According to one aspect of the present invention, web pages incorporating internal content are presented using content management utility <b>330</b>. In one embodiment, transactional assets <b>302</b> and content assets <b>304</b> may be prioritized according to user preferences. Further detail is available for each screen by clicking through to selected items and an on-line reference manual is available for customization options.

0053According to another aspect of the invention, business unit owners can control the content and layout of subtopic areas available to network user systems <b>126</b>. Internal <b>120</b> and external <b>116</b> content providers are provided with a standard mechanism to supply content to the system and a process to communicate technical and design standards. In another aspect of the invention, a set of guidelines, processes and controls for topic owners to maintain topic areas is provided. In one aspect of the present invention, transaction functionality is provided through links to existing applications. In another aspect, detailed content is presented through links to the provider web page. In one embodiment, the system provides support for transactional content.

0054In another embodiment of the present invention, click-stream data <b>320</b>, <b>322</b> is stored in a personal preferences database <b>122</b>. Click-stream data may derive from content pages <b>320</b> or transactional pages <b>322</b> accessed by a network user <b>126</b>. In addition to click-stream data <b>320</b>, <b>322</b>, data from the personal profile data store <b>124</b> may also be transferred to and stored in the personal preferences database <b>122</b>. Eventually, information such as user registration/authentication <b>318</b>, transactional assets <b>302</b>, content assets <b>304</b>, and click-stream data <b>320</b>, <b>322</b>, after passing through one or more components of the application server system <b>334</b>, is transmitted to an interactive presentation service <b>332</b>. This interactive presentation service <b>332</b> is any hardware and/or software suitably configured to create the look and feel of network user system's <b>126</b> web site.

0055<figref idref="DRAWINGS">FIG. 4</figref> is a flow diagram depicting in further detail an exemplary flow of information through web server <b>112</b> (<figref idref="DRAWINGS">FIG. 1</figref>). (In <figref idref="DRAWINGS">FIG. 4</figref>, application server tier <b>104</b> is not shown, to simplify the diagram.) The diagram displays web server <b>112</b> architecture, which utilizes, for example, JSP integration with servlets in a command bean framework and XML document structure services create a web page on a digital display <b>202</b>. In one embodiment of the present invention, information is transferred from backend systems tier <b>102</b> to either user profile access bean <b>410</b> or a messaging service <b>412</b> via HTTP <b>422</b>, wherein user profile access bean <b>410</b> can be any form of personal profile service. From user profile access bean <b>410</b>, information is sent to a presentation bean <b>416</b> and then, for example, to a web page on a digital display <b>202</b>, wherein presentation bean <b>416</b> can be any form of data request handler. Information from messaging service <b>412</b> is transmitted to presentation bean <b>416</b>, a public data access bean <b>418</b> or a private data access bean <b>420</b> and then to a web page on a digital display <b>202</b>. Public data access bean <b>418</b> can be any form of public data service and private data access bean <b>420</b> can be any form of private data service. Information may also flow from a web page on digital display <b>202</b> to backend systems tier <b>102</b>. Such information may pass directly to user profile access bean <b>410</b> and then to backend systems tier <b>102</b> via XML <b>424</b>. Alternatively, information may be transferred from a web site to a messaging data access bean <b>414</b> and then to messaging service <b>412</b>. From messaging service <b>412</b>, information is then sent to backend systems tier <b>102</b> via XML <b>424</b>. In one embodiment, web server <b>112</b> further includes a network security service <b>442</b>. Information passing between user system <b>126</b> with digital display <b>202</b> and the various components of web server <b>112</b> described above, may first be required to pass through network security service <b>442</b>.

0056<figref idref="DRAWINGS">FIG. 5</figref> is a combination flow diagram and architectural diagram showing an exemplary method of handling information flow from client tier <b>108</b> to backend systems tier <b>102</b> and from backend systems tier <b>102</b> back to client tier <b>108</b>. Initially, an HTTP post/get request <b>510</b> is initiated from client tier <b>108</b> to web server tier <b>106</b>. This data is then encapsulated within the presentation layer application of web server tier <b>106</b>. The information is then sent via an HTTP post <b>512</b> to application server tier <b>104</b> for data acquisition and aggregation by one of the application server's business specific functions. The presentation layer elements may include, for example, any combination of JavaBeans, JSPs, Java classes, and any other convenient code hosted on web servers <b>106</b> configured to communicate with the servlets via HTTP. This process may be repeated several times in order to aggregate information on the main page. Information from client tier <b>108</b> that is processed by web server tier <b>106</b> and application server tier <b>104</b> is then sent to backend systems tier <b>102</b> via outgoing JDBC/LDAP <b>514</b>. Backend systems tier <b>102</b> then processes the data and sends it back to application server tier <b>104</b> via incoming JDBC/LDAP <b>516</b>. This data is then transferred to web server tier <b>106</b> as XML data <b>518</b> and to client tier <b>108</b> as HTML data <b>520</b>.

0057In one embodiment of the present invention, to minimize coupling between the presentation and application layers, a Command Bean framework is used. As is known, command beans act as interface adapters to system components belonging to different functional domains, and provide the functionality to invoke various services in accordance with the invention. By implementing a command bean, interfaces exposed by external content providers <b>116</b> (shown in <figref idref="DRAWINGS">FIG. 1</figref>) can be changed independently by implementing the changes through the command beans. Multiple external content providers <b>116</b>, providing similar functionality, can be integrated with the same command bean. In an alternative embodiment, each command bean may correspond to a single business logic task such as a query task, update task or any other such tasks as may be desired. With continued reference to <figref idref="DRAWINGS">FIG. 1</figref>, the command bean framework substantially isolates application server tier <b>104</b> from changes that could occur in the interface supported by external content providers <b>116</b>. In one embodiment of the invention, the implementation of external content providers <b>116</b> or mediators that acquire data from backend systems tier <b>102</b> is modifiable (e.g. from Java servlets to Enterprise JavaBeans) without substantially impacting client tier <b>108</b> by effecting corresponding changes in the command beans.

0058In order to control how documents are presented to network user system <b>126</b>, XML tags may be used. To process and dynamically generate XML documents, according to one embodiment, web server tier <b>106</b> function is extended by the XML Document Structure Services in application server tier <b>104</b>. This enables database connectors and integration applications to parse, generate, manipulate, and validate XML-based dynamic content. This content is sent to client tier <b>108</b> and interchanged with other servlets. Alternatively, web server tier <b>106</b> may be used to selectively apply stylesheets to XML documents when client tier <b>108</b> devices do not support XSL stylesheets to XML documents.

0059It should be understood that the exemplary processes illustrated above may include more or fewer steps or may be performed in the context of a larger processing scheme. Although the invention has been described herein in conjunction with the appended drawings, those skilled in the art will appreciate that the scope of the invention is not so limited. Modifications in the selection, design, and arrangement of the various components and steps discussed herein may be made without departing from the scope of the invention as set forth in the appended claims.
