Abstract

Payment card information of a consumer is protected during online payment card based transactions by equipping a user device of the consumer with a control that, when activated by the consumer during an online shopping session, causes the user device automatically to request and receive, from a third-party payment processing service (PPS), temporary proxy payment card information, and to populate that information into an online transaction web interface of the merchant. The temporary proxy payment card information is associated in the third-party PPS with a real payment card account of the consumer. When the PPS receives a transaction authorization request from a merchant via a payment card network, the PPS uses the consumer's real payment card information to authorize the transaction. The consumer's real payment card information is never exposed to the merchant.

Description

RELATED APPLICATIONS

This application claims priority to and is a continuation of U.S. patent application Ser. No. 14/453,551, filed on Aug. 6, 2014, the entire contents of which are incorporated herein by reference.

FIELD OF THE INVENTION

At least one embodiment of the present invention pertains to electronic commerce, and more particularly, to a technique for enhancing security of sensitive data during online transactions involving payment card accounts.

BACKGROUND

When purchasing goods or services online (e.g., via the Internet), a consumer may be given the option to pay by credit card or other type of payment card (e.g., debit card or gift card). To do so, after adding one or more items to his or her electronic shopping cart and requesting checkout, the consumer typically enters his or her payment card information into a web page generated by a shopping cart application of the merchant. Once the payment card information is entered, the consumer provides a confirmation input that indicates his or her commitment to the transaction and that causes his or her user device to submit payment information to the website of the merchant. The merchant's computer system then requests authorization of the card transaction through a financial system.
One problem with this payment paradigm is that it exposes sensitive information of the consumer, namely, the consumer's payment card information, to various third parties, where it may be vulnerable to misappropriation. For example, the payment card information may be inadvertently provided by the consumer to a wrongdoer posing as a legitimate online merchant. Additionally, merchants sometimes store the consumer's card information. Different merchants implement vastly differing degrees of data security, such that the consumer's card information may be vulnerable to unauthorized acquisition by hackers once it is in the possession of a merchant.

DETAILED DESCRIPTION

In the technique introduced here, credit card or other payment card information of a consumer (also called the “cardholder” or “user” herein) is protected during online payment card based transactions, by enabling a user device of the consumer to request and receive, during an online shopping session, temporary proxy payment card information from a third-party payment processing service (PPS), and by enabling the user device to populate that temporary proxy payment card information into an online transaction web interface of the merchant automatically. In some embodiments, this is accomplished by equipping a browser in the user device with a control that, when activated by the consumer, accesses the PPS to obtain the proxy card information populates that information into the online transaction web interface of the merchant automatically. The temporary proxy payment card information is associated in the third-party PPS with a real payment card account of the consumer. When the merchant requests authorization for the transaction with the proxy payment card information, the authorization request gets routed to the PPS via the payment card network, by virtue of the proxy card number, according to the normal authorization request routing process. The PPS then uses the consumer's real payment card information to authorize and fund the transaction.
Hence, the consumer's real payment card information is never exposed to the merchant or to any unauthorized third parties who penetrate the merchant's information systems. Additionally, this technique is completely transparent to the merchant and therefore requires no modifications to the merchant's e-commerce system.
Consider the following example scenario in which the technique can be applied. The PPS is a secure business enterprise and computer system that is highly trusted by the consumer. A consumer initially enrolls with the PPS by setting up an account with the PPS, which includes providing his or her real credit card information to the PPS. Enrollment with the PPS may be done via a website of the PPS, by telephone, electronic mail, standard mail, or any other convenient communication channel. The consumer further installs a software extension or plug-in associated with the PPS into a conventional web browser (e.g., Microsoft Internet Explorer, Mozilla Firefox or Google Chrome) in a user device used by the consumer. The user device may be, for example, a conventional personal computer (PC), such as a desktop computer or laptop computer, or it may be a smartphone, tablet computer, or any other known or convenient processing device.
The consumer later visits an electronic commerce (e-commerce) website of a merchant, which may be a merchant with whom the consumer is not familiar and in whom the consumer does not have a high level of trust. The consumer adds one or more items to his or her electronic shopping cart and requests checkout. The consumer then clicks a button to activate the PPS browser extension, by which the consumer can pay securely through the PPS. When activated, the extension accesses the PPS (which is implemented at least partially on one or more remote server computers) via a network such as the Internet, to obtain a dynamically generated credit card number, along with corresponding card type information, cardholder name, expiration date and card verification value (CVV); this information collectively is the temporary proxy payment card information (or simply proxy card information). The proxy card information can include a valid Visa or Mastercard number, for example, and may be issued by the PPS. Once received from the PPS, the PPS browser extension automatically populates the proxy card information into the merchant's website's checkout page (e.g., a web form). The PPS is subsequently contacted as the card issuer during the credit card payment authorization process.
Note that while the example of a credit card is used herein to facilitate description, the proxy card information can be associated in the PPS with any other type of real payment card, such as a debit card or a gift card, for example.
The PPS can maintain validity rules that limit the validity of the proxy card information, such as by time, merchant, transaction amount, number of transactions, or any other criteria. These rules may be specified or selected by the consumer (prior to the transaction), or they may be default rules provided by the PPS. The validity rules include at least one validity criterion, which can be or include, for example, a maximum individual or collective transaction amount and/or a maximum number of transactions for which the proxy card information can be used, particular merchant or category of merchant in which the proxy card information can be used, etc. The validity criterion further can be or include an expiration date and/or time for the proxy card information, which can be different from the expiration date of the consumer's real payment card. Furthermore, the expiration date/time of the proxy card information can also be different from the proxy expiration date provided to the merchant website, i.e., it can be earlier than or later than the proxy expiration date. In other words, the proxy card expiration date provided to the merchant may be a dummy expiration date that does not reflect the actual expiration date/time of the proxy card information or the expiration date of the consumer's real payment card information.
For example, the validity rules might specify that the proxy card information can be used only once, or only once per day, or only once per day per merchant, or only for specific merchants or categories of merchants, or only for up to $2,500 per month, or combination of such restrictions. From the merchant's perspective, the consumer is using a normal payment card number (and associated information). From the consumer's perspective, they just enter minimal PPS authentication information (e.g., username and password) once, or at most once per user session. From the PPS's perspective, they receive an authorization request through the proxy card information and then use the consumer's real card information on file to authorize and fund the transaction.
If the merchant is the target of a hacking attack directed to its stored card information, all they have of the consumer is a name and card information that has no value, because the information is single-use or very limited use, and the PPS can deactivate all proxy card numbers used at that merchant without having to the deactivate the backing payment cards.
FIG. 1 illustrates an example of an environment in which the data security technique can be implemented. The environment includes at least one user device 1A or 1B (collectively user device 1) of a consumer, which can be, for example, a mobile device 1A such as a smartphone or tablet, or a PC 1B. The environment further includes an e-commerce website 2 of a merchant, a computer system 3 of the PPS (hereinafter the PPS system 3), and a financial system 4 for processing payment card transactions. The PPS system 3 includes a database 5 storing information such as identification information of users enrolled with the PPS, real payment card account information of such users, and an association of that account information with proxy card information for at least some users.
Though not shown in FIG. 1, the financial system 4 can include the merchant's acquiring bank and at least one payment card payment network, such as Visa or MasterCard, and computer systems associated with such entities. Each of the aforementioned computer systems can include one or more distinct physical computers and/or other processing devices which, in the case of multiple devices, can be connected to each other through one or more wired and/or wireless networks. All of the aforementioned devices are coupled to each other through an internetwork 6, which can be or include the Internet and one or more wireless networks (e.g., a WiFi network and/or a cellular telecommunications network).
Referring now to FIG. 2, the user device 1 and the PPS system 3 are shown in greater detail, according to at least one embodiment. As illustrated, the user device 1 includes a browser 21, which in the illustrated embodiment includes a user-installable extension (plug-in) 22 associated with the PPS. In the case of a mobile user device, the PPS client-side functionality may be implemented, for example, by a bookmarklet (i.e., a browser bookmark containing executable script such as JavaScript).
The PPS system 3 includes, for each consumer enrolled with the PPS, information 23 identifying the consumer and/or the consumer's user device (hereinafter “user/device information”), real payment card account information 24 of the consumer, and proxy payment card information 25 associated with the consumer. Additionally, the PPS system 3 includes a card information proxying unit 26 and a payment authorization unit 27. The card information proxying unit 26 is responsible for maintaining the association between the consumer's user/device information 23, real card account information 24 and proxy card account information 25, and for looking up and providing proxy card account information 25 to the user device 1 when required. The payment authorization unit 27 is responsible for determining whether to authorize requested payment card transactions, including applying stored validity rules 28 associated with the proxy card information 25.
In some embodiments, the PPS system 3 may associate a particular consumer with two or more different sets of proxy payment card accounts, all of which may be associated in the PPS system 3 with the same real payment card of the consumer or with two or more different real payment cards of the consumer. In such an embodiment, the particular proxy payment card information to be used for a given transaction can be selected using any of various techniques, such as by user selection on a per-transaction basis, based on selection rules or policies previously specified by the user, or based on default rules or policies. The real payment card or cards associated with a particular consumer in the PPS system 3 (and hence, with a particular set of proxy payment card information) can include one or more credit cards, debit cards, gift cards, or a combination thereof.
In operation, when the consumer activates a known browser control associated with the PPS plug-in 22, the PPS plug-in 22 sends information of the consumer to the PPS. In certain embodiments, the PPS plug-in first prompts the consumer to enter his or her identifying information to be used by the PPS to authenticate the consumer, such as a username and password. This information can be input one time and then stored locally in the user device for future use, or it may be input by the consumer for each online transaction or each user session. The user/device information may be sent to the PPS system 3 via any known or convenient network or internetwork, such as the Internet. When the user/device information is received by the PPS system 3, the card information proxying unit 26 uses the user/device information to look up the proxy card account information 25, which it then returns to the PPS plug-in 22. The PPS plug-in 22 then populates the received proxy card account information into the payment information user interface provided by the merchant's website 2, which may be a web form. The receipt of proxy card information and population of that information into the merchant's user interface normally happens within a few seconds (at most), of the consumer activating the PPS browser control. In an alternative embodiment, the proxy card information may simply be displayed to the user, who then manually copies that information into the merchant's payment information user interface.
When the user commits to the transaction by providing an appropriate confirmation input, the merchant e-commerce website 2 sends a transaction authorization request to its acquiring bank, which routes the request to the applicable card network (e.g., Visa or MasterCard) based on the proxy payment card number, which then routes the request to the PPS system 3. The payment authorization unit 27 in the PPS system 3 then uses the proxy payment card number in the request to look up the applicable validity rules or rules 28 associated with the proxy payment card information and determine whether the transaction request complies with them. If the request does not comply with any applicable validity rule(s) 28, the authorization request is denied. If the request does comply, then the payment authorization unit 27 looks up the real payment card information 24 of the consumer and uses that information to authorize the transaction, assuming the consumer's real payment card has not expired and has sufficient credit or funds remaining to cover the transaction amount.
In some embodiments, instead of implementing this technique with a browser extension on the client side, the PPS client-side functionality may be provided by a separate software application or dedicated PPS hardware device that operates in the consumer's user device 1. In that scenario, the PPS can publish an application programming interface (API) for other software vendors, to allow browsers and/or e-commerce software to invoke the PPS functionality. In that case, the user can easily switch back and forth between a browser or e-commerce application and the PPS client-side application/functionality, to request and receive proxy payment card information.
FIG. 3 illustrates an example of the message flow between various elements associated with this technique, according to some embodiments. When the consumer is requested by a merchant's e-commerce website to enter payment information for a transaction, the consumer enters an appropriate user input 31 associated with PPS functionality, to the user device 1. FIG. 4A shows an example of a merchant's initially empty payment information webpage 44 (e.g., an HTML form or the like). The above-mentioned user input 31 can be in the form of the consumer clicking on a “PPS” button 45 or other similar control, displayed (e.g., by the PPS plug-in) on the webpage 44.
In response to user input 31, the user device 1 sends a proxy card information request 32 to the PPS system 3. The request may be sent using any known or convenient protocol(s), including, for example, Hypertext Transport Protocol Secure (HTTPS).
Note that in this description, any references to sending or transmitting a message, signal, etc. to another device (recipient device) means that the message is sent with the intention that it its information content ultimately be delivered to the recipient device; however, such references do not mean that the message must be sent directly to the recipient device. That is, unless stated otherwise, there can be one or more intermediary entities that receive and forward the message, signal, etc., either as is or in modified form, prior to its delivery to the recipient device. This clarification also applies to any references herein to receiving a message, signal, etc. from another device; i.e., direct point-to-point communication is not required unless so stated.
In response to the proxy card information request 32, the PPS system 3 generates or looks up the proxy payment card information for that user, and returns it to the user device in a proxy card information response 33. The PPS functionality in the user device 1 then automatically populates this information into the payment card information fields 46 (e.g., card type, card number, security code (CVV), expiration date and name on card) in the merchant's payment information webpage 44. Alternatively, the consumer can manually copy that information into the merchant's payment information webpage 44. An example of the result of this operation is shown in FIG. 4B, which shows the webpage 44 of FIG. 4A after the card information fields 46 have been populated.
In certain embodiments, to provide additional fraud protection, the PPS system 3 can use a different proxy payment card number for each merchant or category of merchants. Additionally, or as an alternative, the PPS system 3 can generate different combinations of proxy CWs and/or proxy expirations dates with the same proxy payment card number, and can use a different combination of such information for each merchant or category of merchant. The use of such combinations provides a greater number of unique permutations of proxy payment card information, thereby reducing the overall exposure to wrongdoers.
When the consumer is ready to commit to the transaction, he or she enters an appropriate user input 34 to the user device 1, for example, by clicking on a “Pay Now” button 47. This causes the user device 1 to send a conventional transaction confirmation message 35 (e.g., using HTTPS or other similar protocol) containing the proxy card information to the merchant's e-commerce website 2. The merchant's e-commerce website 2 then sends a transaction authorization request 36 to the financial system 4. The financial system 4 routes the request in the form of message 37 to the PPS system 3. The PPS system 3 determines whether to authorize the transaction in the manner described above, and sends an authorization response 38 (e.g. authorized or declined) to the financial system 4, which forwards the response in the form of message 39 to the merchant's e-commerce website 2. The merchant's e-commerce website 2 then sends an appropriate message 40 confirming or denying the transaction to the user device 1, which displays 41 the message to the consumer.
FIG. 5 illustrates an example of a process performed by the consumer's user device 1, according to some embodiments. Initially, in response to a user input, a browser in the user device accesses the website of an online merchant at step 501. At step 502 the browser displays a window including a shopping cart page of the merchant, where the window includes a control for the PPS (e.g., “PPS” button 45). When the consumer activates the PPS control at step 503 (after having added one or more items to his or her shopping cart and requested checkout), the PPS functionality in the user device 1 then at step 504 prompts the consumer for and receives PPS authentication information (e.g., username and password), if such information was not previously input by the consumer and stored locally in the user device. Next, at step 505 the user device 1 sends a message including the consumer's authentication information to the PPS system 3. Assuming the user is properly authenticated by the PPS system 3, the user device 1 receives a message containing the proxy card information from the PPS system 3 at step 506. The user device 1 then at step 507 appropriately populates the payment card information fields of the merchant's payment information page with the proxy card information.
FIGS. 6A and 6B illustrate examples of processes performed by the PPS system 3, in association with the example of FIG. 5, according to some embodiments. More specifically, FIG. 6A shows an example of the process for providing proxy card information to the user device 1. Initially, at step 601 the PPS system 3 receives a message including the consumer's authentication information from the user device 1. The PPS system 3 responds by looking up the consumers account information based on the authentication information at step 602. Based on the account information, the PPS system 3 at step 603 retrieves the proxy card information associated with consumer's account if that information was previously generated and stored in the PPS system 3, or generates the proxy card information if it was not previously generated and stored. The PPS system 3 then sends a message containing the proxy card information to the user device at step 604.
FIG. 6B shows an example of the process by which the PPS system 3 processes a subsequent transaction authorization request. At step 611 the PPS system 3 receives a transaction authorization request containing proxy card information, from the financial system 4, based on a corresponding authorization request originated by the merchant's e-commerce website 2. At step 612 the PPS system 3 responds to the authorization request by determining whether the request complies with the validity rule or rules, stored in the PPS system 3, associated with the proxy card information in the request. As described above, the rules include one or more of validity criteria for the proxy card information, such as a time limit, merchant identity or category restriction, transaction amount limit, etc., or a combination thereof. If the request does not comply with all applicable validity rules (step 613), then the PPS system 3 at step 618 sends a message for delivery to the merchant's e-commerce website 2, indicating that the transaction is denied. If, on the other hand, the request complies with all applicable validity rules (step 613), the PPS system 3 at step 614 looks up the real payment card account associated with the proxy card information, and then determines at step 615 whether the transaction can be authorized based on the real payment card account information (e.g., whether the real payment card is not expired and has sufficient credit or funds available to cover the transaction amount). If the PPS system 3 determines that the transaction can be authorized based on the real payment card account information (step 616), the PPS system 3 sends a message at step 617 for delivery to the merchant's e-commerce website, indicating that the transaction is authorized; otherwise, the process branches to step 618, where the PPS system 3 sends a message for delivery to the merchant's e-commerce website 2, indicating that the transaction is denied.
FIG. 7 illustrates at a high-level an example of the hardware architecture of a processing system that can be used to implement any of the computing devices referred to above, such as the user device 1, the merchant website 2, the PPS system 3, or the financial system 4. Note that any of these devices each can include multiple instances of an architecture such as shown in FIG. 7 (i.e., multiple computers), particularly the server-based systems such as the merchant website 2, PPS system 3, and financial system 4, and such multiple instances can be coupled to each other via a network or multiple networks.
