Researchers Submit Patent Application, "Dynamic Account Identifier with Return Real Account Identifier", for Approval

July 3, 2014



By a News Reporter-Staff News Editor at Computer Weekly News -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors Aabye, Christian (Foster City, CA); Byrne, Brian (San Francisco, CA), filed on December 9, 2013, was made available online on June 19, 2014.

No assignee for this patent application has been made.

News editors obtained the following quote from the background information supplied by the inventors: "The use of tokenization is becoming increasingly popular in the context of electronic payment transactions using credit card accounts, debit card accounts, prepaid accounts, checking accounts, and the like. Tokenization refers to the process of converting financial account information, such as a primary account number (PAN) or other real account identifier into an account token, which may be used in lieu of the real account identifier to conduct an electronic payment transaction with a merchant for goods or services. For instance, a tokenization algorithm can be used to transform a real account identifier into an account token by replacing all or a portion of the real account identifier with one or more valueless stand-in numbers, letters, symbols, or other characters, or the real account identifier can be replaced altogether by a different static or dynamic value.

"Account tokens may be stored and utilized by merchants and acquirers (e.g., in customer 'cards on file' databases), by users (e.g., on a payment card or accessible via an electronic wallet client facilitated by a mobile device), issuers, processors, and other entities that participate in electronic payment transactions. Although the use of account tokens can provide advantages such as improved security and convenience, such tokens may also introduce a number of disadvantages. For instance, merchants or acquirers may need access to real account identifiers to facilitate returns, refunds, and other post-transaction activity. Similarly, since the relationship between an account token and a specific user may not be readily ascertainable, real account identifiers may be needed by merchants or acquirers to perform services such as customer loyalty programs, analytics, targeted marketing, and the like. Moreover, account token formats may be incompatible with existing clearing and settlement processes and infrastructure utilized by acquirers, issuers, payment processing networks, and the like.

"Some of the aforementioned disadvantages may be remedied by real account identifiers being provided to merchants and their acquirers as part of the electronic payment transaction flow. However, providing such sensitive information for all transactions may negate many of the advantages provided by account tokens, such as the ability to protect the customer's privacy from hackers, fraudsters, and unscrupulous merchants.

"Embodiments of the present invention address these problems and other problems individually and collectively."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "Embodiments of the invention are directed to systems, apparatus, and methods for receiving an account token for a transaction, and returning an associated real account identifier if the transaction is approved.

"One embodiment of the invention is directed to a method. The method comprises receiving, by a server computer, an authorization request message for a transaction, the authorization request message including an account token associated with a real account identifier. The server computer determines the real account identifier associated with the account token. If the transaction is approved, an authorization response message including the real account identifier is transmitted.

"Another embodiment of the invention is directed to a server computer comprising a processor and a computer-readable medium coupled to the processor. The computer-readable medium includes code executable by a processor for performing a method. The method comprises receiving an authorization request message for a transaction, the authorization request message including an account token associated with a real account identifier. The real account identifier associated with the account token is determined. If the transaction is approved, an authorization response message including the real account identifier is transmitted.

"Another embodiment of the invention is directed to a method comprising receiving, by a merchant computer, an account token from a payment device, the account token being associated with a real account identifier. The merchant computer transmits an authorization request message for a transaction to a server computer, the authorization request message including the account token. The server computer determines the real account identifier associated with the account token and, if the transaction is approved, transmits an authorization response message including the real account identifier.

"Another embodiment of the invention is directed to a system comprising a payment device, a merchant computer, and a server computer. The payment device is configured to store an account token associated with a real account identifier. The merchant computer is configured to receive the account token from the payment device, and transmit an authorization request message for a transaction including the account token. The server computer is configured to receive the authorization request message including the account token from the merchant computer, determine the real account identifier associated with the account token, and transmit an authorization response message including the real account identifier if the transaction is approved.

"These and other embodiments of the invention are described in detail below.
