    摘要: Disclosed are methods and systems for enabling an assertion to be provided to a relying entity that is associated with a discount or digital coupon for an item in a transaction. The assertion may indicate an interaction by a user device with a digital indicator associated with the item and/or a resource provider offering the item. The assertion may be associated with a user and redeemed at a later time to apply a discount for an item involved in a transaction. The assertion may indicate an interaction with a digital indicator at one location for an item and redeemed at another location, including an online transaction, for the same item.

    摘要: A method includes receiving, by a universal authentication application from a resource provider computer, a user credential verification request message comprising a user identifier, server computer data, and interaction data for an interaction. The universal authentication application transmits the user credential verification request message to a browser that invokes the authenticator to verify biometric information of a user. The universal authentication application receives a user credential verification response message from the authenticator. The user credential verification response message includes signed interaction data. The universal authentication application sends the user credential verification response message to the resource provider computer. The resource provider computer provides at least the signed interaction data to a plurality of server computers to retrieve a plurality of portable device credentials respectively associated with the plurality of server computers.

    摘要: A method conducted using a mobile device is disclosed. The method includes maintaining a plurality of software modules, wherein each software module of the plurality of software modules is built and executed independently of other software modules. The mobile device receives first interaction initiation data corresponding to a first transaction. In response to receiving the first interaction initiation data, a first subset of the plurality of software modules is selected via an application interface to execute the first transaction. The mobile device receives second interaction initiation data corresponding to a second transaction. In response to receiving the second interaction initiation data, a second subset of the plurality of software modules to execute the second transaction is selected via the application interface. The first subset of the plurality of software modules is different than the second subset of the plurality of software modules.

    摘要: Improvements to post-quantum lattice-based digital signature schemes are disclosed. By sampling cryptographic material, including cryptographic key matrices and masking vectors from a uniform distribution, embodiments eliminate the need for a security check during generation of a digital signature vector. As a result, digital signatures can be generated faster and at a lower failure rate. A generating device can generate a verification matrix A and a secret matrix S from a uniform distribution, and an error matrix E from a special distribution (such as a Gaussian). The generating device can combine the three matrices to generate a public matrix Y. The first and the fourth matrices (A, Y) can be used as a public key used to verify digital signatures. The second and the third matrices (S, E) can be used as a private key used to generate digital signatures.

    摘要: Systems, methods, and computer program products may receive, from a merchant system, an authorization request associated with a transaction; communicate the authorization request to an issuer system and initiate a response timer associated with the transaction; in response to the response timer satisfying a predetermined response time amount without receiving, from the issuer system, an authorization response associated with the authorization request, determine an extended response time; and in response to receiving the authorization response from the issuer system before the response timer satisfies a sum of the extended response time amount and the predetermined response time amount, communicate, to the merchant system, the authorization response.

    摘要: Provided herein are systems and methods for rapid activation of electronic payment devices with a mobile device. The method includes generating, with at least one processor, activation data corresponding to a non-activated electronic payment device issued to a user, storing, on an activation element associated with the electronic payment device, a unique identifier corresponding to the electronic payment device, receiving, with at least one processor, an activation request from a mobile device in response to the user scanning the activation element with the mobile device, the activation request comprising identification data associated with the user and the unique identifier, determining, with at least one processor, that the activation data matches the identification data, and, in response to determining that the activation data matches the identification data, activating the electronic payment device.
