Using discretionary data fields to secure transactions comprises a payment system employing a server configured to associate a payment account of a user with a user computing device, the payment account comprising a payment account identifier that identifies the payment account, and establish a authentication challenge and an corresponding challenge response. The payment system receives a first payment authorization request originating from a merchant computing system comprising the payment account identifier, data associated with the payment account identifier, and a request to fund a transaction using the payment account, wherein the data associated with the payment account identifier comprises a challenge response provided by the user computing device located in a discretionary data field. The payment system compares the provided challenge response with the corresponding challenge response, and approves the transaction based on whether the provided challenge response and the corresponding challenge response match.
The present disclosure relates generally to digital wallet account transactions, and more particularly to using discretionary data fields to secure transactions.
Digital wallet accounts on payment processing systems enable users to utilize a user computing device to conduct transactions. A user applies the wallet account to a transaction with the merchant's point-of-sale system via near field communication, WI-Fi, Bluetooth, infrared, or in any suitable manner. The payment processing system can utilize the provided financial account to conduct the transaction with the merchant.
Digital wallet accounts and user computing devices often have certain authorization and authentication procedures to reduce fraud. For example, a user computing device may require a password to access the digital wallet application module. However, conventional systems do not allow the user computing device to provide security information to a payment processing system via the discretionary data field on a payment instrument.
Techniques herein provide a computer-implemented method to use discretionary data fields to secure transactions. A payment system employs a server configured to associate a payment account of a user with a user computing device, the payment account comprising a payment account identifier that identifies the payment account, and to establish an authentication challenge and a corresponding challenge response. The payment system receives a first payment authorization request originating from a merchant computing system, the first payment authorization request comprising the payment account identifier, data associated with the payment account identifier, and a request to fund a transaction using the payment account, wherein the data associated with the payment account identifier comprises a challenge response provided by the user computing device located in a discretionary data field. The payment system compares the provided challenge response with the corresponding challenge response, and replies to the merchant computing system with a responsive authorization state, wherein the responsive authorization state is determined based on the determination whether the provided challenge response and the corresponding challenge response match.
In certain other example aspects described herein, a system and a computer program product to use discretionary data fields to secure transactions.
These and other aspects, objects, features, and advantages of the example embodiments will become apparent to those having ordinary skill in the art upon consideration of the following detailed description of illustrated example embodiments.

FIG. 3 is a block flow diagram depicting a method for the user computing device to communicate payment account information to the merchant POS terminal in the discretionary data field of the payment account information, in accordance with certain example embodiments.
FIG. 4 is an illustration of a user computing device requesting an authentication response, in accordance with certain example embodiments.
FIG. 5 is a block diagram depicting a computing machine and a module, in accordance with certain example embodiments.
In one example embodiment, a user attempts a transaction with a merchant point of sale (“POS”) terminal. When the user selects a payment instrument, such as a credit card, to use, a digital wallet communicates with a payment processing system to obtain an authentication challenge. In certain embodiments, the authentication challenge resides in the user computing device, and the payment processing system does not need to be contacted. The digital wallet populates a discretionary data field of the payment instrument being used with a challenge response. The payment instrument information, including the discretionary data field, is transmitted to a POS terminal to conduct the transaction. The POS terminal communicates the transaction request to the payment processing system. The payment processing system accesses the challenge response from the discretionary data field. If the challenge response is acceptable, then the transaction proceeds.
In one example embodiment of a wallet account, payment processing systems enable users to utilize a payment account to conduct transactions. The user associates one or more financial accounts with the wallet account. For example, the user can associate with the user's wallet account or more debit/credit cards maintained by multiple issuers (including the payment processing system operating as an issuer), stored value cards (for example, gift cards, prepaid cards, re-loadable transaction cards, exchange cards, and other forms of non-credit based value cards), loyalty cards or other store rewards cards, value added service accounts (for example, coupons, vouchers for prepaid offers, redemption offers, and other forms of offers), peer-to-peer transaction accounts, bank accounts and/or other forms of financial accounts.
The wallet account can be represented on a digital wallet application module or other payment application on a user computing device, such as a mobile phone. For example, the user wallet account information, such as a wallet account identifier, can be stored on the user computing device for use in a payment transaction by the digital wallet application module or other application.
To conduct a transaction using a wallet account on a user computing device, the user can communicate the wallet account identifier and other transaction data to a merchant point of sale (“POS”) terminal using the user computing device via near field communication (“NFC”), barcode, BLUETOOTH, Wi-Fi communication, infrared, or other suitable communication technology. Alternatively, the wallet account can have thereto associated a physical payment card comprising a magnetic stripe or other machine-readable portion comprising the user's wallet account identifier and other payment information. In this case, the user scans or swipes the wallet account at the merchant POS terminal to communicate the wallet account identifier and other transaction data to the merchant POS terminal. Additionally or alternatively, the wallet account can be represented as any other suitable payment instrument, such as an RFID device or a smartcard. Additionally or alternatively, the payment account can be a digital wallet application module or other payment account on a user computing device for conducting online transactions, such as a mobile or desktop computer, laptop computer, or a television with one or more processors embedded therein and/or coupled thereto.
Continuing the example of a conventional transaction, the merchant system creates a payment request for the transaction using the wallet account information and forwards the payment request to an acquirer, which forwards the payment request to a card network. The card network forwards the payment request to the payment processing system, which may function as the issuer of the payment instrument for the payment request.
The payment processing system reads wallet account information from the payment request and accesses the user's account associated with the wallet account. If the payment processing system is the issuer of the particular financial account selected as the backing account for the wallet account transaction, the payment processing system will approve or decline the transaction.
If another issuer maintains the particular financial account to be used as the backing account for the transaction, the payment processing system will generate and send a new payment request for the transaction to the other issuer via the card network (or via a different card network). The payment processing system receives an authorization message from the other issuer via the card network if the transaction is approved.
The payment processing system forwards an authorization to the acquirer through the card network, which forwards the authorization to the merchant system. The authorization is based on the payment processing system's determination as the issuer to authorize the transaction or the authorization received from the other issuer.
The merchant system then approves the transaction, based on the authorization received from the payment processing system.
In certain example embodiments, the user and/or the payment processing system establish a security procedure for transactions. The security procedure may be a particular challenge and response, an interrogation of the user computing device, a location verification, or any suitable procedure. The details of example security procedures will be described herein.
In an example embodiment, the user initiates a purchase at a merchant location. The user opens the digital wallet application module executing on the user computing device. The digital wallet application module represents any application or other user interface system the user employs to conduct wallet account and other transactions via the user computing device. The user accesses the wallet account of the user via the digital wallet application module.
The user can select a payment account associated with the wallet account to be the used for the subsequent transaction. In certain embodiments, at the time that a user indicates that a transaction is imminent, such as by opening the digital wallet application module, the user computing device accesses the authentication challenge that has been configured for the account. In one example embodiment, the authentication challenge is stored in the digital wallet application module, on the secure element, in other memory, or in any suitable location on the user computing device. In an alternate example embodiment, at the time that a user indicates that a transaction is imminent, the user computing device contacts the payment processing system to request an authentication challenge. The user computing device may contact the payment processing system over the Internet via a Wi-Fi signal, a cellular communication, an email, a text, or any suitable communication technology. When contacted, the payment processing system transmits the authentication challenge to the user computing device.
In alternate example embodiments, the user computing device accesses the authentication challenge after the merchant POS terminal provides a transaction request to the user computing device. For example, the POS terminal receives an initiation of a transaction and transmits a request to the user computing device to provide payment information. At the time of the request from the POS terminal, the user computing device may access the authentication challenge or request the authentication challenge from the payment processing system.
The authentication challenge may be a challenge/response question for the user. For example, the challenge may be a question for which an answer has been previously configured with the payment processing system. One example question may be “what is your mother's maiden name?” Another question may be “In what city were you born?” Any suitable question may be used. The challenge question may be displayed on the user interface of the user computing device. The user enters the appropriate response into the user interface of the user computing device. The response must be stored on the device and or at the payment processing system if configured prior to the transaction.
In another example, the authentication challenge may be directed to the user computing device. For example, the challenge may be a request for the identification number of the user computing device, the model number of the user computing device, or a similar request. In another example, the payment processing system may request the location of the user computing device. The location may be accessed from a global positioning system (“GPS”) technology on the user computing device, from a Wi-Fi location technology, or any suitable technology. In another example, data from the transaction history of the user computing device may be used. For example, the time or location of the last successful transaction may be requested.
The user computing device communicates payment account information to the merchant point of sale (“POS”) system, comprising the wallet account identification and challenge response. For example, the user can select a product for purchase at a merchant location and conduct the purchase transaction at a POS terminal of the merchant system.
The wallet account information that is stored in the digital wallet application module on the user computing device is used to make a payment to the merchant. The wallet account information is transmitted to the POS terminal via NFC, Bluetooth, barcode displayed via the user computing device, Wi-Fi, or other form of communication. The user can initiate the communication by performing a wireless “tap” of the user computing device with the POS terminal or any other suitable action, such as by actuating a real or virtual button on the user computing device or speaking a command into the user computing device. In an alternative example embodiment, a purchase is initiated by use of an RFID device, smartcard, barcode displayed on the user computing device, or other suitable medium that can be read by the POS terminal.
When a transaction is initiated, the digital wallet application module can access the wallet account information residing in the digital wallet application module or other secured or unsecure storage in the user computing device, including the challenge response. If a challenge response has been supplied by the user or by the user computing device, then the digital wallet application module includes the response in the transaction details being transmitted to the POS terminal. The response may be transmitted in a discretionary data field of the wallet account information. As the challenge response may be located in a discretionary data field, the challenge response is not utilized by the merchant system or the POS terminal; however, the challenge response information is still communicated to the payment processing system by the merchant system.
In an example embodiment, the challenge response is the answer provided by the user to a challenge question. In another example, the challenge response is a GPS location of the user computing device. In another example, the challenge response is an identification number of the user computing device. In another example, the challenge response is specific transaction related data that was requested from the user computing device, such as the time of the last transaction.
A payment authorization request is communicated to the payment processing system from the POS terminal. The request includes the wallet account identification and challenge response. The POS terminal communicates a payment authorization request to the payment processing system to obtain payment for the purchase transaction between the user and the merchant. The payment authorization request comprises transaction details, such as the product being purchased, the total price, the merchant system information, the wallet account information, and other suitable data.
The payment processing system receives the payment authorization request and determines if the challenge response is accepted. Along with the wallet account information, the payment processing system identifies the challenge response from the provided data. The payment processing system accesses the wallet account of the user based on the wallet account information provided in the request and determines if the challenge response is appropriate. For example, the payment processing system can determine if an answer provided by the user matches the configured expected answer. In an example, the expected answer to the question “What is your mother's maiden name?” is “Jones.” If the user answered “Jones,” and the answer was transmitted to the payment processing system, then the payment processing system determines that the challenge response is accepted.
In another example, the challenge response is the GPS location of the user computing device. The payment processing system determines the expected GPS location of the user computing device based on the location of the merchant identified in the transaction details. For example, the user computing device identifies the merchant and accesses the location of the merchant from a database of merchant locations. The payment processing system compares the location of the merchant with the location of the user computing device. If the locations match, then the payment processing system determines that the user computing device is located at the merchant and the likelihood of a fraudulent transaction is reduced.
In another example, the challenge response is a detail from a recent transaction. The user computing device determines the last transaction conducted by the user with the user computing device and extracts a particular detail, such as the time of the last transaction. The payment processing system compares the time of the last transaction of the user computing device with the time of the last transaction stored in a memory of the payment processing system. If the times match, then the payment processing system determines that the user computing device is the same user computing device previously used and the likelihood of a fraudulent transaction is reduced.
Any suitable response to a suitable challenge may be provided. For example, an identification number of the user computing device or a personal identification number.
If the wallet account on the payment processing system functions as a proxy account, then the payment processing system can initiate a second transaction with an issuer of the selected backing account to fund the merchant transaction. The payment processing system can transmit an approval or refusal of the transaction to the merchant system, based on approval or refusal of the transaction with the selected backing account.
The payment processing system approves the transaction based on transaction details and challenge response. If the challenge response is accepted and the transaction is approved, then the payment processing system transmits the approval to the POS terminal. The merchant system receives the approval, provides the purchased product or service to the user, and logs the transaction. The transaction funds are remitted to the merchant system.
Turning now to the drawings, in which like numerals represent like (but not necessarily identical) elements throughout the figures, example embodiments are described in detail.

FIG. 2 is a block flow diagram depicting a method 200 for using discretionary data fields to secure transactions, in accordance with certain example embodiments.
With reference to FIGS. 1 and 2, in block 205, user 101 establishes a wallet account with the user computing device 110 and the payment processing system 140. In an example embodiment, the user 101 requests a wallet account using a web server 141, and the wallet account is associate with the user 101. The user 101 may be issued an account number to be used for transactions via the Internet before or after a physical card is received. In an alternative example embodiment, the payment processing system 140 mails an inactivated wallet account card to the user 101. The wallet account is then activated by the user 101 before use. In an example embodiment, a physical wallet account card is not issued. The wallet account information can be stored in the user computing device 110 and is used to make a payment via a NFC, Bluetooth, barcode, Wi-Fi, or other form of wireless tap of the user computing device 110 with the point of sale (“POS”) terminal 134. In an alternative example embodiment, the purchase is initiated when the user 101 enters an account identification number at the POS terminal 134 or in the user computing device 110. The account identification number may be the wallet account number or a different number that links the payment transaction to the wallet account. In yet another alternative example embodiment, a purchase is initiated by use of a permanent/temporary virtual/physical token QR code, bar code, or other suitable machine-readable medium that is read by the POS terminal 134. In these cases, the POS terminal 134 may comprise a scanner, camera, or other reading device that captures the wallet account information, such as a bar code or QR reader or other suitable reading device. The wallet account information may be printed in paper or other form.
In block 210, the user 101 and/or the payment processing system 140 establish a security procedure for transactions. The security procedure may be a particular challenge and response, an interrogation of the user computing device, a location verification, or any suitable procedure. The details of example security procedures are described herein.
In block 215, the user 101 initiates a purchase at a merchant system 130 location, a website, or at any virtual location. The user 101 opens the digital wallet application module 111 executing on the user computing device. The digital wallet application module 111 represents any application or other user interface system the user 101 employs to conduct wallet account transactions and other transactions via the user computing device 110. The user 101 accesses the wallet account of the user 101 via the digital wallet application module 111 of the user computing device 110. The user 101 may select a payment account associated with the wallet account to be the used for the subsequent transaction.
In block 220, at the time that the user 101 indicates that a transaction is imminent, the user computing device 110 accesses the authentication challenge that has been configured for the account. In one example embodiment, the authentication challenge is stored in the digital wallet application module 111, on the secure element or other secure memory, or in any suitable location on the user computing device 110. In certain embodiments, the challenge request may be updated by the payment processing system 140 when the user computing device 110 and the payment processing system 140 are in communication. In an alternate example embodiment, at the time that a user 101 indicates that a transaction is imminent, the user computing device 110 contacts the payment processing system 140 to request an authentication challenge. The user computing device 110 may contact the payment processing system 140 over the Internet via a Wi-Fi signal, a cellular communication, an email, a text, or any suitable communication technology. When contacted, the payment processing system 140 transmits the authentication challenge request to the user computing device 110.
In alternate embodiments, the user computing device 110 accesses the authentication challenge after the merchant POS terminal 134 provides a transaction request to the user computing device 110. For example, the POS terminal 134 receives an initiation of a transaction from the user 101 or a merchant system operator, and transmits a request to the user computing device 110 to provide payment information. At the time of the request from the POS terminal 134, the user computing device 110 may access the authentication challenge.
The authentication challenge may be a challenge/response question for the user 101. For example, the challenge may be a question for which an answer has been previously configured with the payment processing system 140. One example question may be “What is your mother's maiden name?” Another question may be “In what city were you born?” Any suitable question may be used. The challenge question may be displayed on the user interface of the user computing device 110. The user enters the appropriate response into the user interface of the user computing device.
FIG. 4 is illustration of a user computing device requesting authentication data, in accordance with certain example embodiments. The user computing device 110 is illustrated on a user interface screen 305 of the user computing device 110. The user interface displays a credit card 102 which the user 101 has indicated will be used for a transaction. The user interface displays the challenge question 310 “In what city were you born?” The user 101 is provided a module 315 to enter the response challenge. In the example, the user may type the response with a keyboard associated with the user computing device 110.
In another example, the authentication challenge may be directed to the user computing device 110. For example, the challenge may be a request for the identification number of the user computing device 110, the model number of the user computing device 110, or a similar request. In another example, the authentication challenge may request the location of the user computing device 110. The location may be accessed from a global positioning system (“GPS”) technology on the user computing device, from a Wi-Fi location technology, or any suitable technology. In another example, data from the transaction history of the user computing device 110 may be used. For example, the time or location of the last successful transaction may be requested. The user computing device 110 accesses the challenge request and determines the appropriate response. The response may be accessed from the memory of user computing device 110 or received from the user 101 input.
Returning to FIG. 2, in block 225, the user computing device 110 communicates payment account information to the merchant POS terminal 134 in the discretionary data field of the payment account information. The details of block 225 are described in further detail with regard to method 225 in FIG. 3.
FIG. 3 is a block flow diagram depicting a method for the user computing device 110 to communicate payment account information to the merchant POS terminal 134 in the discretionary data field of the payment account information, in accordance with certain example embodiments.
In block 226, the user computing device 110 identifies the challenge response from user computing device 110 data or from user 101 input. In an example, the user computing device 110 accesses the challenge from the memory of the user computing device 110 or from the payment processing system 140. The user computing device 110 accesses the challenge response from the memory of the user computing device 110 or from an input of the user 101.
In block 227, the user computing device 110 incorporates the response into the discretionary data field of the wallet account information. The user computing device 110 identifies the discretionary data field of the payment account information that is available for discretionary data input. The user computing device 110 inserts the challenge response into the discretionary data field.
In block 228, user computing device 110 communicates the wallet account information to the POS terminal 134. The wallet account information is transferred to the POS terminal 134 via NFC, Bluetooth, barcode, Wi-Fi, or other form of communication. The user 101 can initiate the communication by performing a wireless “tap” of the user computing device 110 with the POS terminal 134 or any other suitable action, such as by actuating a real or virtual button on the user computing device 110 or speaking a command into the user computing device 110. In an alternative example embodiment, a purchase is initiated by use of an RFID device, smartcard, barcode displayed on the user computing device 110, or other suitable medium that can be read by the POS terminal 134.
When a transaction is initiated, the digital wallet application module 111 can access the wallet account information residing in the digital wallet application module 111 including the challenge response. If a challenge response has been supplied by the user 101 or by the user computing device 110, then the digital wallet application module 111 can include the response in the transaction details being transmitted to the POS terminal 134.
The response may be transmitted to the POS terminal 134 in the discretionary data field of the wallet account information. Data fields of conventional wallet account information may be made up of information related to the wallet account. For example, a data field may contain a format code, a primary account number, a user name, an expiration date, a longitudinal redundancy check, or other suitable data. A discretionary data field may be included in the conventional wallet account information. Conventional wallet accounts may include in the discretionary data field a PIN verification key a card verification code. In the example, the challenge response is incorporated into the discretionary data field. The challenge response may replace other discretionary data or be added to other discretionary data.
As the challenge response can be located in a discretionary data field, the response is not utilized by the merchant system 130 or the POS terminal 134; however, the merchant system 130 communicates the challenge response in the discretionary data field to the payment processing system 140 with the transaction details.
In an example embodiment, the challenge response is the answer provided by the user 101 to a challenge question. In another example, the challenge response is a GPS location of the user computing device 110. In another example, the challenge response is an identification number of the user computing device 110. In another example, the challenge response is specific transaction related data that was requested from the user computing device 110, such as the time of the last transaction.
Returning to FIG. 2, in block 230, a payment authorization request is communicated to the payment processing system 130 from the POS terminal 134. The request includes the wallet account identification and challenge response. The POS terminal 134 communicates a payment authorization request to the payment processing system 140 to obtain payment for the purchase transaction between the user 101 and the merchant system 130. The payment authorization request comprises transaction details, such as the product being purchased, the total price, the merchant system information, the wallet account information, and other suitable data. The request may be transmitted via an acquirer, to the credit card network, and then to the payment processing system 140.
In block 235, the payment processing system 140 receives the payment authorization request and determines if the challenge response is accepted. Along with the wallet account information, the payment processing system 140 identifies the challenge response from the provided data. The payment processing system 140 accesses the wallet account of the user 101 and determines if the challenge response is appropriate. The payment processing system 140 reads the wallet account identification information from the payment authorization request and identifies the wallet account from the account identifier information. The payment processing system 140 identifies the challenge response that is stored in the discretionary data field. The payment processing system 140 determines if the challenge response matches an expected response. If the response matches, the payment processing system 140 approves the transaction as long as the other transaction details are appropriate (such as, the payment amount being within an amount authorized).
For example, to determine if the challenge response matches and expected response, the payment processing system 140 can determine if an answer provided by the user matches the configured expected answer. In an example, the expected answer to the question “What is your mother's maiden name?” is “Jones.” If the user answered “Jones” and the answer was transmitted to the payment processing system 140, then the payment processing system 140 determines that the challenge response is accepted.
In another example, the challenge response is the GPS location of the user computing device 110. The payment processing system 140 determines the expected GPS location of the user computing device 110 based on the location of the merchant system 130 identified in the transaction details. For example, when the payment processing system 140 identifies the challenge response in the discretionary data field of the wallet account information, the user computing device 110 identifies the merchant system 130 from the transaction information. The payment processing system 140 accesses the location of the merchant system 130 from a database of merchant system 130 locations. The payment processing system 140 compares the location of the merchant system 130 with the location of the user computing device 110. If the locations match, then the payment processing system 140 determines that the user computing device 110 is located at the merchant system 130 and the likelihood of a fraudulent transaction is reduced.
In another example, the challenge response is a detail from a recent transaction. The user computing device 110 determines the last transaction conducted by the user 101 with the user computing device 110 and extracts a particular detail, such as the time of the last transaction. The payment processing system 140 compares the time of the last transaction of the user computing device 110 with the time of the last transaction stored in a server 141 of the payment processing system 140. If the times match, then the payment processing system 140 determines that the user computing device 110 is likely to be the same user computing device 110 previously used and the likelihood of a fraudulent transaction is reduced.
Any suitable response to a suitable challenge may be provided. For example, an identification number of the user computing device 110 or a personal identification number from the user 101.
In block 240, if the wallet account on the payment processing system 140 functions as a proxy account, then the payment processing system 140 may initiate a second transaction with an issuer of the selected backing account to fund the merchant transaction. The payment processing system 140 may transmit an approval or refusal of the transaction to the merchant system 130, based on approval or refusal of the transaction with the selected backing account. If the payment processing system 140 is the issuer of the payment account, the payment processing system 140 authorizes the transactions, if all conditions are met and the challenge response is accepted.
The payment processing system 140 approves transaction based on transaction details and challenge response. If the challenge response is accepted and the transaction is approved, then the payment processing system 140 transmits the approval to the POS terminal 134. For the transaction to be approved, the payment processing system 140 determines if certain configurable conditions are met, such as determining if the account is active, if the funds available must be lower than the amount of funds requested in the authorization requested, if certain fraudulent transaction conditions are not met, or any other suitable determinations. The merchant system 130 receives the approval, provides the purchased product or service to the user 101, and logs the transaction.
The transaction funds are remitted to the merchant system 130 from the payment processing system 140. The funds may be transmitted at a later time upon settlement of the transaction.
In certain embodiments, the transaction is an online transaction. In an example, the challenge response is included in the discretionary data field of the account identifier that is provided to a merchant server 135 in the online transaction. The challenge request and the challenge response may utilize any of the techniques described herein in a manner consistent with an online transaction.
