DETAILED DESCRIPTION
• In some example embodiments, a system and method is shown for using a token to address online fraud in an EPFN. In one example embodiment, the number that appears on a physical credit, debit cards, or a bank account number is replaced with an identifier (e.g., a token) that is generated by a depository financial institution server. In some example embodiments, this token is associated by an account holder with a merchant. An account holder is a person having an account with a depository financial institution that controls a depository financial institution server. The merchant, in one example embodiment, may use the token in facilitating an online commercial transactions engaged in by the account holder. An online commercial transaction includes a transaction in commerce conducted over a network.
• In some example embodiments, account holders instruct their depository financial institution, and the servers they control, to generate a token and send it to a merchant/merchant aggregator server. This token may be sent over a network. These instructions can be generated by the account holder through the depository financial institution server. A depository financial institution includes, for example, a national, state of thrift chartered bank, a credit union, a savings and loan, or other suitable institution.
• Some example embodiments may include an enrollment program to facilitate the use of tokens by account holders in online commercial transactions. In one example embodiment, pre-enrollment is used by a depository financial institution to facilitate participation by account holders. In another example embodiment, account holder enrollment is facilitated by merchants who solicit account holders to utilize tokens in conducting online commercial transactions.
• In some example embodiments, an EPFN may include a bankcard or payment processor networks such as VISA™ and MASTERCARD™, EFT networks such as STAR™, PULSE™, or NYCE™, or even a file transfer networks such as the Automated Clearing House (ACH) network. The EPFN may also include a core bank process, or outsourced bank processing (e.g., as provided by Metavante Corporation, or Jack Henry Corporation). The token, in some example embodiments, is generated through the use of a hash algorithm, digital signature, or symmetric or asymmetric key algorithm. In some example embodiments, the token is generated through the use of time based rolling encryption. Additionally, the token may be a pseudo-number, alpha-numeric value, a 128-bit value, 256-bit value, a pointer to a location in physical or virtual memory, or some other suitable value. The token may be verified using a Public Key Infrastructure (PKI), or a Pretty Good Protection (PGP) web of trust.
Example System Architecture
• FIG. 1 is a diagram of anexample system100 illustrating token generation and authentication. Prior to making a request for authentication, an account holder registers once with some authenticating entity, such as a depositoryfinancial institution server112, on that their identity can later be verified. This depositoryfinancial institution server112 may be part of a PKI, or a PGP web of trust. The depositoryfinancial institution server112 generates authentication tokens on behalf of the account holder. The depositoryfinancial institution server112 may be controlled by a bank.
• An account holder may use adevice102, perhaps taking the form of a cellular telephone in some embodiments, to inform the depositoryfinancial institution server112 that authentication tokens have been requested. Atoken request118 is generated and transmitted to the depositoryfinancial institution server112. In one example embodiment, upon the entry of selected information (e.g., logging into a bank account controlled by the account holder with a username and password), the depositoryfinancial institution server112 generates and issues one or more tokens to the account holder. Such tokens may take the form of a numeric value, one or more smart cards, a magnetic card, a Radio Frequency Identification (RFID) device, a bar code, or a printed piece of paper. Tokens may be physically generated, or electronically generated, perhaps in the form of anemail message120 to thedevice102.
• Once the tokens have been generated, they may be presented at a number of locations for authentication. In this manner, the account holder need only register one time with an authenticating entity, and thereafter, authentication may be accomplished using tokens, so that little or no information is passed on to various other entities (e.g., an unknown vendor) for inspection prior to various transactions taking place. An example of an authenticating entity is a merchant or merchant aggregator and server controlled by the merchant or merchant aggregator.
• Here it can be seen that asystem100 for taken generation and authentication may receive a token104, and anauthentication request106 to authenticate the token104. Thisauthentication request106 may be received at an Internet Service Provider (ISP)server110 representing a vendor or other party requesting authentication of the token104. In some example embodiments, theISP server110 may be controlled by a merchant or merchant aggregator. An example of a merchant aggregator is PAYPAL™. The request for authentication of the token104 may be entered using aclient terminal116 with aGUI117 Thedevice102 is an example of aclient terminal116. One example of such a request might be initiated by scanning a smart card having an embedded RFID device with the token recorded thereon. Another might be scanning a bar code, either as presented by a account holder on a printed piece of paper, or perhaps, as displayed on a cellular telephone. A further example of such a request may be the providing of a numeric value via an internet connection by the account holder.
• Responsive to receiving the request, theISP server110 may forward the token104 as part of amessage144 to the depositoryfinancial institution server112. The depositoryfinancial institution server112 may represent the financial entity or other entity that has registered the identity of the account holder seeking authentication by the vendor (e.g., represented by the ISP server110). If the token is matched by the depositoryfinancial institution server112, then amessage148 announcing that authentication was successful may be returned to theISP server110 from the depositoryfinancial institution server112, and thereafter, to theclient terminal116.
• FIG. 2 is a diagram of anexample system200 used to complete an EFT based transaction utilizing a depository financial institution server to verily the identity of a purchaser. Shown is adevice102 in the form of a cell phone. Thisdevice102 generates and transmits apurchase request201 that is received by a merchant/merchant aggregator server202. The merchant/merchant aggregator server202 may be controlled by a merchant aggregator such as PAYPAL™. Thispurchase request201 may be in the firm of a request for a particular target resource that may reside upon or be accessible from the merchant/merchant aggregator server202. A target resource may include a good or service that can be purchased. A Single Sign On (SSO)verification203 is transmitted by the merchant/merchant aggregator server202 across a network to be received by thedevice102. Thedevice102 may utilize thisSSO verification203 to generate aSSO service request204. ThisSSO service request204 includes an EFT account number associated with the user of thedevice102. TheSSO service request204 is received by afinancial network server205. Thefinancial network server205 may be controlled by STAR™, Thefinancial network server205 transmits an accountholder verification request206. This accountholder verification request206 is received by the depositoryfinancial institution server112. The accountholder verification request206 includes a key value. A key value may be a numeric value, hash value, digital signature, symmetric or asymmetric key value. This key value is compared to an existing key value on file with the depositoryfinancial institution server112. Where the key value corresponds to an account holder, conformation/denial207 is generated confirming the identity of the party tendering a purchase request to thefinancial network server205. The depositoryfinancial institution server112 generates an account holder confirmation/denial207. This account holder confirmation/denial207 is received by thefinancial network server205. Anaccount verification208 is generated byfinancial network server205. This account verification may include a Security Assertion Markup Language (SAML) response. Thisaccount verification208 is received by thedevice102. Upon receiving theaccount verification208, thedevice102 may be utilized to complete or otherwise consummate the purchase of the good or service identified in thepurchase request201. In some example embodiments, based upon the receipt of theaccount verification208, further purchases of good or services may be completed using thedevice102.
• FIG. 3 is a diagram of anexample system300 utilizing a back-channel communication between the merchant/merchant aggregator server202 and thefinancial network server205 to verify the identity of a purchaser in a transaction utilizing EFT. Shown is thedevice102 that generates apurchase request301. Thispurchase request301 is received by the merchant/merchant aggregator server202. The merchant/merchant aggregator server202 generates apurchase verification request302 and transmits thispurchase verification request302 to thefinancial network server205. Associated with thispurchase verification request302 may be an EFT account number and a device ID. The device ID may include a unique identifier for thedevice102. A Media Access Control (MAC) address, an International Mobile Equipment Identity (MEI) address or an Electronic Serial Numbers (ESNs) address are examples of device IDs. Thefinancial network server205 generates an accountholder verification request303 that is received by the depositoryfinancial institution server112. The depositoryfinancial institution server112 generates a confirmation, where the device ID corresponds to the device ID on file for the financial network account holder seeking to engage in an EFT transaction. The depositoryfinancial institution server112 generates an account holder confirmation/denial304 that is received by the financial network.server205. Based upon whether an account holder confirmation or denial is included in the account holder confirmation/denial304, anaccount verification305 is provided to the merchant/merchant aggregator server202. Thisaccount verification305 may include a token or may include a denial of thepurchase request301. The merchant/merchant aggregator server202 generates aconfirmation306 and provides this to thedevice102 confirming the purchase requested in thepurchase request301.
• FIG. 4 is a diagram of anexample system400 wherein a bi-directional relationship between a depository financial institution server and a merchant/merchant aggregator server is used to complete an account holder purchase. Shown is aGUI401 who, using anGUI407 associated with one ormore devices102, generates ashopping selection409. Thedevice102 includes, for example, acell phone403,computer system404,television405, or a Personal Digital Assistant (PDA)406. Similarly, theuser408 generates ashopping selection410 using on thedevice102, and theuser409 generates ashopping selection412 using thedevice102.Users401,408, and409 may be account holders. Theshopping selections409,410 and412 are transmitted across thenetwork413 and received by the merchant/merchant aggregator server202. Theseshopping selections409,410, and412 include account holder information, or other information used to uniquely identify the account holder to the merchant/merchant aggregator server202. Thenetwork413 may use anyone of a number of protocols including an Internet Protocol (IP), an Asynchronous Transfer Mode (ATM) protocol, a Data Over Cable Service Interface Specification (DOCSIS) protocol, Secure Sockets Layer (SSL), Transport Layer Security (TLS), or some other suitable protocol. Further, thenetwork413 may have an architecture including a Virtual Private Network (VPN) architecture, a Local Area Network (LAN), or Wide Area Network (WAN) architecture and associated topology. Operatively connected to the merchant/merchant aggregator server202 is the depositoryfinancial institution server112. The depositoryfinancial institution server112 receives a purchase request using customerunique ID414. The purchase request using customerunique ID414 includes data relating to the purchase as reflected in theshopping selections409410, and412. This data may include price information, quantity information, or other suitable information. The purchase request using customerunique ID414 is received from the merchant/merchant aggregator server202 by the depositoryfinancial institution server112. The purchase request using customerunique ID414 may include a token that is compared by the depositoryfinancial institution server112 against value tokens for the merchant/merchant aggregator server202. Where sufficient funds exist for the purchase, anauthorization reply415 is generated to signify an authorization of the purchase. Theauthorization reply415 is received by the merchant/merchant aggregator server202. Theauthorization reply415 may include a boolean value or flag. Theauthorization reply415 is received by the merchant/merchant aggregator server202. In some example embodiments, a further embodiment of this method is through the use of an EPFN that is connected to one or more banks.
• FIG. 5 is a diagram of anexample system500 wherein a purchase is made by an account holder that involves the use of a financial network server. In some example embodiments, the purchase request usingcustomer ID504 is generated based upon theshopping selections501,502, and503. Theseshopping selections501 through503 include account holder information, or other information used to uniquely identify the account holder to the merchant/merchant aggregator server202. The purchase request usingcustomer ID504 is received by thefinancial network server205, and forwarded to the depositoryfinancial institution server112. In some example embodiments, thefinancial network server205 may track which depositoryfinancial institution server112 issued token and which merchant/merchant aggregator server202 received the token. A mapping may exist on thefinancial network server205 between a particular token and the merchant/merchant aggregator server202. This tracking is performed so as to validate that the merchant/merchant aggregator server202 is entitled to use the token. The purchase request using customerunique ID504 may include a token that is compared by the depositoryfinancial institution server112 against tokens associated with the merchant/merchant aggregator server202. Anauthorization reply501 is generated by the depositoryfinancial institution server112 and transmitted to thefinancial network server205. Further, theauthorization reply501 is transmitted to the merchant/merchant aggregator server202.
• in some example embodiments, upon receipt of the purchase authorization request (e.g., the purchase request using customer ID504), thefinancial network server205 may ensure that the token is valid. Further, thefinancial network server205 may ensure that the token comes from the merchant/merchant aggregator server202 to whom the token was assigned. Validity may be determined based upon certain predefined parameters such as the size of the token, the confirmation of a symmetric or asymmetric key value, a digital signature, hash digest value, numeric range reflected in the token, or other suitable criteria. In some example embodiments, if the token is invalid or if it comes from any other merchant that is not the merchant to whom the token was sent, the network may decline the purchase authorization request. If the token is valid, the network may forward the purchase authorization request to the bank that, in turn, may perform additional checks to ensure the transaction can be approved.
• FIG. 6 is a diagram of anexample system600 illustrating an enrollment process for an account holder in a bi-directional relationship between a depositoryfinancial institution server112 and a merchant/merchant aggregator server202. In some example embodiments,enrollment instructions610,611, and612 are generated by the user (e.g., account holders)401,408, and409 and thedevice102 utilized by these users. Theseenrollment instructions610,611, and612 may include uniquely identifying account holder information. This uniquely identifying account holder information includes, for example, social security number information, physical address information, and answers to challenge questions, a unique numeric value known to the account holder. Additionally, illustrated is the depositoryfinancial institution server112 operatively connected to the merchant/merchant aggregator server202. In some example embodiments, the depositoryfinancial institution server112 generates a customerunique ID615. This customerunique ID615 is a token.
• In some example embodiments, account holders initiate enrollment in response to an offer or solicitation to link their bank account, or any other financial account, to a merchant or merchant aggregator account. The linked account referenced herein is a funding account. The customerunique ID615 may be mapped to a particular customer name, where the customer is an account holder of the depository financial institution that controls the depositoryfinancial institution server112. Upon receiving theseenrollment instructions610 through612, the depositoryfinancial institution server112 generates a token (e.g., the customer unique ID615) that the banks can tater translate into funding account numbers (e.g., a number representing a financial account). The funding account for the account holder can be a deposit account, credit lines, or other suitable account. Account holders and financial institutions have control over which accounts are to be used to fund purchases. The token generated is sent to merchants using a secure channel (e.g., the network413) along with other personal information that allows merchants, via the merchant/merchant aggregator server202 or web server controlled by the merchant, to create an account associating the token with a particular account holder. In some example embodiments, the depositoryfinancial institution server112 also stores the token along with specific information about the merchant that received the token.
• In some example embodiments, during the purchase process account holders log on at the selected merchant web site and instruct the merchant to use the pre-stored tokens to pay for a specific purchase. Merchants send the purchase information to banks using a proprietary link passing the token as the pointer to the financial account to be used to fund the purchase. Upon receipt of the purchase authorization request banks may ensure that the token is valid and that it comes from the merchant to whom the token was assigned. If the token is invalid or if it comes from any other merchant that is not the merchant to whom the token was sent, the token originating bank may decline the purchase authorization request. If the token is valid and the request passes all other normal checks (e.g. enough money in the funding account), the bank may approve the purchase authorization request.
• FIG. 7 is a diagram of anexample system700 that uses a EPFN to enroll an account holder user and allow the account holder to participate in a transaction with a merchant/merchant aggregator server202. Shown areenrollment instructions610,611, and612 that are transmitted to the depositoryfinancial server112 across thenetwork413.Enrollment instructions610 through612 are provided to the depositoryfinancial institution server112. Theseenrollment instructions610 through612 may be aggregated into the enrollment instructions701 and provided to thefinancial network server205. Enrollment instructions701 may be a numeric value(s) tracked by the depositoryfinancial institution server112, where each value corresponds to a particular account holder. A consumerunique ID703 in the form of a token is provided to the merchant/merchant aggregator server202. The depositoryfinancial institution server112 tracks which merchant/merchant aggregator server202 received the token. During the purchase process, account holders log on at the selected merchant web server, and instruct the merchant to use the pre-stored tokens to pay for a specific purchase. The merchant sends the purchase information across thenetwork413 to the depositoryfinancial institution server112 to be used to verify the purchase.
• FIG. 8 is a diagram of anexample system800 to facilitate account holder enrollment, Shown areenrollment notifications801 that are generated by the depositoryfinancial institution server112. Also shown is a consumer unique ID802 (e.g., a token) that is also generated by the depositoryfinancial institution server112. Theenrollment instructions801 are provided to thedevices102 operated by theusers401,408, and409. Theenrollment instructions801 are segregated intospecific enrollment instructions803,804, and805 for specific users (e.g., account holders). For example,enrollment notification803 are provided touser401,enrollment instructions804 are provided to theuser408, andenrollment instructions805 are provided to theuser409. Theseenrollment notifications801, and803 through805 may be in the form of Uniform Resource Identifier (URI) formatted data that enables an account holder to enroll or otherwise utilize the system and method illustrated herein.
• FIG. 9 is a diagram of anexample system900 illustrating the receipt of an enrollment instructions with code that is received by merchant/merchant aggregator server202. In some example embodiments, enrollment instructions withcode903 through905 is generated by each of thedevices102 controlled by theusers401,408, and409 respectively. These various enrollment instructions withcode903 through905 are aggregated into the enrollment instructions withcode901. The enrollment instructions withcode901 is received by the merchant/merchant aggregator server202. The merchant/merchant aggregator server202 generates an enrollment request withcode902 that is transmitted to the depositoryfinancial institution server112. The depositoryfinancial institution server112 generates an enrollment reply consumer unique ID906 (e.g., a token) that is transmitted to and received by the merchant/merchant aggregator server202. An example of the enrollment instructions withcode901, and903 through905 is a messages that includes account holder information transmitted using Hypertext Transfer Protocol over Secure Socket Layer (HTTPS), the TLS protocol, or SSL protocol.
• FIG. 10 is a diagram of anexample system1000 that uses an enrollment mailer to solicit account holders to utilize or enroll in the system and method illustrated herein. In some example embodiments, the depositoryfinancial institution server112 generates an enrollment mailer with a sign upcode1002. This mailer may be an email received from a server controlled by their financial institutions asking them to enroll in the service. The mailer may include some form of unique code assigned to each account holder. The enrollment mailer with a sign upcode1002 may be transmitted across thenetwork413 as a enrollment mailer with a sign upcode1003 through1005. Each of these enrollment mailer with a sign upcode1003 through1005 may be received by thedevices102 controlled by theusers401,408, and409. These enrollment mailer with a sign upcode1002, and1003 through1005 may be in the form of URI formatted data that enables an account holder to enroll or otherwise utilize the system and method illustrated herein.
• In some example embodiments, when account holders tog on at a participating merchant web site, they provide their e-mail, the sign up code, and some other form of information known to them and their financial institution with which they have an account (e.g., the last four digits of their bank account number). The merchant/merchant aggregator server202 may forward the information to the depositoryfinancial institution server112 that may validate the information provided against its own records and reply to the merchant with the unique token for further commercial transactions as shown inFIG. 1 above.
Example Interfaces
• FIG. 11 is a simplified diagram illustrating anexample GUI407 according to various embodiments of the system and method. ThisGUI407 is one of many that are possible. In the particular example ofFIG. 11, a sample web page that might be seen by an account holder that has logged into his bank account on the Internet is shown, Here, the “TOKEN”option1104 has been selected, calling up theTOKEN GENERATION PAGE1108. This selection permits the account holder account owner to select aparticular account1112 that can be used to generate tokens. Here it can be seen that several fields, such as atime limit field1116, a number presentedfield1120, and avendor list field1140 may be populated with various information.
• For example, after an account holder selects anaccount1112 to be used in conjunction with token generation, perhaps from a number of accounts in an account field, a time limit for token validity may be set in field1116 (e.g., 24 hours after generation, the token will no longer be valid for authentication purposes). The account holder may also select how many times the token may be presented (e.g., 10) using thefield1120. Finally, a limited selection of entities that can request authentication may also be selected. In this way, the useful lifetime and other breadth of use characteristics for particular tokens may be limited, providing increased security. The account holder may also specify information to be shared with requesting parties by the authenticating entity upon successful authentication, perhaps using thesharing field1136.
• Once the limiting selections have been made, the account holder account owner might simply click on a generate widget button (not pictured) to generate a token. In some embodiments, amessage field1128 in theGUI407 may be used to inform the individual account holder when the last token was generated. Other fields in theGUI407 may be used to provide additional selection alternatives.
• FIG. 12 is a block diagram illustrating another example of aGUI407 according to various embodiments of the system and method. ThisGUI407 is one of many that are possible. In the particular example ofFIG. 12, a sample web page that might be seen by a vendor that has logged into an authentication entity web page on the Internet is shown. Here, the “VERIFY”option1244 has been selected, calling up theAUTHENTICATION PAGE1248. This selection permits the vendor (e.g., the requesting party) to enter a token into an authentication system by a number of methods, including manually typing in a coded value into thetoken field1252. Other methods of entry include electrical (e.g., direct contact pads), electronic (e.g., RFID), and optical (e.g., bar code) scanning.
• The time and date may be entered into the time/date field1216, and the party making the request may identify themselves in thevendor field1220. The authentication entity may be selected using theverification field1240. For security purposes, any of thefields1252,1216,1220, and1240 may be auto-generated by the authenticating entity (e.g., the depository financial institution server112).
• To authenticate the token, the requesting party might simply click on an authentication widget (not pictured). The validity of the token (and therefore authentication of the identity of the account holder, such as a customer of the vendor) may be indicated by simple GO, NO-GO or GOOD/BAD indicators. Upon successful authentication,certain information1232 may be shared with the requesting party. Here, for example, the name, physical address, and the email address of the account holder are shared. Other information, obtained at the time of registration or thereafter by the authenticating entity, may also be shared, if requested by the requesting party and permitted by the account holder. Such information may be specified as part of the token generation activity (shown inFIG. 2). In some embodiments, amessage field1228 in theGUI407 may be used to inform the requesting party when the last authentication occurred, either with respect to the particular token being authenticated, or perhaps with respect to the vendor requesting authentication.
• In some example embodiments, a machine implemented method is used to generate tokens through TRBE. In this scenario both depository financial institutions and merchants exchange a secret hash function, or encryption algorithm. For example, this could be a bilateral algorithm shared between one bank and one merchant, a multi-lateral algorithm shared between one bank and multiple merchants, or a network based algorithm that is applicable to all participating banks and all participating merchants. When the account holder enrolls, banks pass along —instead of the token—a seed value that is unique by account holder. When the account holder indicates he/she wants to purchase something from a participating merchant, the merchant retrieves the seed value associated with the account holder and it feeds it to the algorithm creating a token which is then sent to the depository financial institution for authorization. This algorithm could also be time based, wherein the seed is a numeric value generated by a clock.

• FIG. 24 is a flow diagram illustrating anexample method2400 according to various embodiments of the system and method. For example, a computer-implementedmethod2400 may begin atblock2413 with registering one time, at an authenticating entity, information comprising an identity uniquely associated with an account holder having a financial account held by the financial entity.
• Registering atblock2413 may include obtaining, verifying, and recording the information according to customer identification program (CIP) requirements, Know Your Customer (KYC) requirements, Know Your Business (KYB) requirements, and watch-list scanning requirements. Such requirements are well-known to those of ordinary skill in the art. The information may comprise one or more of the name of the account holder, the birth date of the account holder, the physical address associated with the account holder, and/or an identification number associated with the account holder (e.g., social security number, hash-coded identification number). Registering may also comprise obtaining, verifying, and recording a prior verification associated with the customer by the financial entity against Customer Identification Program (CIP) requirements, Know Your Customer (KYC) requirements, Know Your Business (KYB) requirements and watch-list scanning requirements, for example.
• Themethod2400 may continue on to block2421 with receiving a request at the authenticating entity from a requesting party that has been presented with a token to authenticate a customer purporting to be a particular account holder, The requesting party may comprise a vendor, another financial entity, a brokerage, a lender, a car lot, an online auction provider, etc. Receiving the request may include receiving a message from the requesting party at the authenticating entity via a global computer network (e.g., the Internet).
• At this point, an attempt is made to match the token presented to the identity of the account holder. Thus, themethod2400 may include at block2425 authenticating, by the authenticating entity, such as a bank or other financial entity, the customer as the account holder by matching a token presented by the customer to the identity uniquely associated with the account holder. If no match is determined at block2425, themethod2400 may include requesting, if the authenticating is not successful, additional information from the customer atblock2429. One or more additional attempts, perhaps limited in number by the authenticating entity, may be made to authenticate the identity of the account holder by matching the token with the identity at2425.
• If authentication succeeds at block2425, themethod2400 may include notifying the requesting party that the customer has been authenticated as the account holder by sending a message (e.g., an email message) to the requesting party, perhaps via a global computer network., atblock2433. For example, themethod2400 may include sending a message to a mobile device associated with the customer that the authenticating has been successful. This mobile device may also be used to present the token for authentication, perhaps by transmitting it electronically, or by displaying a bar code image on its display screen (e.g., a PDA or cellular phone display).
• Themethod2400 may go to include, atblock2435, storing the information in an authentication database. For security reasons, the authentication database may be linked to, but physically separate from, a database of accounts including a financial account associated with the account holder whose identity is being authenticated.
• At this point, themethod2400 may include providing to the requesting party a portion of a profile associated with the account holder, which the account holder previously authorized the financial entity to share (e.g., name, physical address, social security number, email address, telephone number, etc.).
• in some embodiments, themethod2400 includes generating one or more tokens by a financial entity (or any other authentication entity) upon request by the account holder atblock2441. Generating tokens atblock2441 may include generating tokens having: one or more of an expiration time period after which presentation of the token by the customer is ineffective; a selected number of requesting parties to which the token may be presented; a selected number of times the token may be presented; and named requesting parties to whom the token may be presented. Other limitations may be imposed.
• Themethod2400 may go on to block2445 with transmitting the token to the account holder. Transmitting may comprise sending an email message, perhaps including the token, to the account holder.
• In some embodiments, themethod2400 may include receiving funds from a customer, such as, an amount associated with a transaction, or some other amount, atblock2449. Thus, for example, themethod2400 may include establishing a new account at a bank associated with an authenticated account holder to hold the funds without receiving any further information from the customer atblock2451. That is, a new account may be opened at a financial entity that is not the authenticating entity, solely on the basis of authenticating the identity of an account holder using a token. Another example includes receiving an amount associated with a transaction associated with a vendor atblock2449, and substantially simultaneously extending credit atblock2455 to the customer by the authenticating entity (e.g., a financial entity), on behalf of the vendor, based on authenticating the identity of a particular account holder, using the token.
• FIG. 25 is a flow diagram illustrating anadditional example method2500 according to various embodiments of the system and method. In some embodiments, a computer-implementedmethod2500 may begin atblock2513 with receiving a token presented by a customer, which may in turn comprise receiving a password entry at a terminal, for example. At substantially the same time the token is received, permission to share selected information from the profile associated with the customer may also be received. Such permission may be entered by the customer into the same terminal as that used to receive the token. Thus, receiving atblock2513 may include receiving the token in conjunction with permission to receive additional information associated with the account holder. In this way, the customer has the option, in some embodiments, of permitting additional information to be shared with the vendor, even after a token is generated. Such additional information might include one or more of the name of an authenticated account holder, the birth date of the account holder, the physical address associated with the account holder, and an identification number associated with the account holder (e.g., driver's license or other license number associated with the account holder).
• Themethod2500 may go on to include transmitting a request to an authenticating entity, such as a financial entity, to authenticate the customer purporting to be a particular account holder atblock2517. At this point, an attempt is made to match the token to the identity registered for the account holder at the authenticating entity.
• If a match between the token and the identity is not obtained atblock2525, then themethod2500 may terminate atblock2527. Of course, repeated attempts to authenticate may also occur, as shown inFIG. 24.

• FIG. 29 is a block diagram illustrating an example client-server architecture to facilitate authentication according to various embodiments of the system and method. Theauthentication system2900 comprises a client-server architecture used for registration, token generation and/or authentication. A financial platform, in the example form of a network-basedfinancial system2902, provides server-side functionality, via a network2980 (e.g., the Internet) to one or more clients.FIG. 29 illustrates, for example, a web client2906 (e.g., a browser, such as the Internet Explorer browser developed by Microsoft Corporation of Redmond, Wash.), and aprogrammatic client2908 executing onrespective client machines2910 and2912. In an example embodiment, either or both ofweb client2906 andprogrammatic client2908 may include a mobile device.
• Turning specifically to the network-basedfinancial system2902, an Application Program interface (API)server2914 and aweb server2916 are coupled to, and provide programmatic and web interfaces respectively to, one ormore application servers2918. Theapplication servers2918 host one or morefinancial applications2920 and authentication applications2922 (e.g., similar to or identical to theauthentication module1938 ofFIG. 19). Theapplication servers2918 are, in turn, shown to be coupled to one ormore database servers2924 that facilitate access to one ormore databases2926, such as registries that include links between account holders, their identity information, and/or financial entity accounts.
• Thefinancial applications2920 provide a number of financial functions and services to users that access the network-basedfinancial system2902. Theauthentication applications2922 facilitate authenticating tokens presented by registered account holders.
• Further, while theauthentication system2900 shown inFIG. 29 employs a client-server architecture, the present application is of course not limited to such an architecture, and could equally well find application in a distributed, or peer-to-peer, architecture system. The various financial andauthentication applications2920 and2922 may also be implemented as standalone software programs, which do not necessarily have networking capabilities.
• Theweb client2906, it will be appreciated, may access the various financial andauthentication applications2920 and2922 via the web interface supported by theweb server2916, Similarly, theprogrammatic client2908 accesses the various services and functions provided by the financial andauthentication applications2920 and2922 via the programmatic interface provided by theAPI server2914. Theprogrammatic client2908 may, for example, comprise an authentication request module (e.g., similar to or identical to theauthentication request module1928 ofFIG. 19) to enable a user to request authentication and to perform batch-mode communications between theprogrammatic client2908 and the network-basedfinancial system2902. Client applications2932 andsupport applications2934 may perform similar or identical functions.
• Thus, theauthentication system2900 may provide a number of registration, token generation, and authentication mechanisms whereby a user may receive tokens for authentication by any number of entities. Thefinancial applications2920 may include one or more account management applications which support and provide services related to various user accounts in a financial entity (e.g. a bank). The various account management applications may also provide a number of features such as supervising account transfers, holding account balances, and keeping tracking of and reporting transactions to relevant applications.
• Thefinancial applications2920 may also include dispute resolution applications to provide mechanisms whereby disputes arising between transacting parties may be resolved. For example, the dispute resolution applications may provide guided procedures whereby the parties are guided through a number of steps in an attempt to settle a dispute. In the event that the dispute cannot be settled via the guided procedures, the dispute may be escalated to a customer service agent for thefinancial system2902, third party mediator, or arbitrator.
• Some embodiments may include the various databases (e.g.,2620, and2731) being relational databases, or, in some cases, On Line Analytic Processing (OLAP)-based databases. In the case of relational databases, various tables of data are created and data is inserted into and/or selected from these tables using a Structured Query Language (SQL) or some other database-query language known in the art. In the case of OLAP databases, one or more multi-dimensional cubes or hyper cubes, including multidimensional data from which data is selected from or inserted into using a Multidimensional Expression (MDX) language, may be implemented. In the case of a database using tables and SQL, a database application such as, for example, MYSQLT™, MICROSOFT SQL SERVER™, ORACLE 8I™, 10G™, or some other suitable database application may be used to manage the data. In this, the case of a database using cubes and MDX, a database using Multidimensional On Line Analytic Processing (MOLAP), Relational On Line Analytic Processing (ROLAP)), Hybrid Online Analytic Processing (HOLAP), or some other suitable database application may be used to manage the data. The tables or cubes made up of tables, in the case of, for example, ROLAP, are organized into an RDS or Object Relational Data Schema (ORDS), as is known in the art. These schemas may be normalized using certain normalization algorithms so as to avoid abnormalities such as non-additive joins and other problems. Additionally, these normalization algorithms may include Boyce-Codd Normal Form or some other normalization or optimization algorithm known in the art.
• FIG. 30 is anexample RDS3000. Shown is a table3001 that includes token IDs. These token IDs may be stored as an integer, string, or some other suitable data type. A table3002 is illustrated that includes account holder data. This account holder data may be stored as a string, eXtensible Markup (XML) data type, or some other suitable data type. A table3003 is shown that includes merchant IDs. These merchant IDs may be stored as an integer, string or XML data type. In some example embodiments, the token IDs of table3001 may be mapped, joined, or otherwise reference the merchant IDs of table3003. A table3004 is shown that includes encryption algorithms. These encryption algorithms may include hashing algorithms, DES, AES, or other suitable algorithms stored as Binary Large Objects (BLOBs). A table3005 is shown that includes unique IDs values stored as integers. These unique IDs may be used to uniquely identify each of the entries in the tables3001 through3004.
