  • Patent number: 11087314
    Abstract: The present disclosure involves systems, software, and computer implemented methods for a remittance system that pre-populates remittance data based on historical usage of remittance transactions. One example system includes operations to generate, using a predictive model, data indicating a predicted likelihood of a user selecting at least one data exchange transaction, wherein the data indicates the predicted likelihood of the user performing the at least one data exchange transaction. A request is received to access a remittance page. In response, the at least one data exchange transaction that was previously generated is selected from a repository of predicted likelihoods. Remittance data associated with a UI element is generated that includes the at least one data exchange transaction. The remittance data is transmitted to the device. An indication from the device is received for interacting with the UI element. The data exchange transaction is executed in response to receiving the indication.

  • Publication number: 20210240778
    Abstract: Systems and methods are provided that use a trained process to reply to a request comprising query data defining a query and context data defining contextual factors for the query from a device. The query is answered by one or more selected APIs of a plurality of APIs that invoke respective services to prepare a response. The trained process determines an execution plan responsive to the query data and the context data and is configured using training to define execution plans comprising selected APIs where a particular API is selected for the plan if it answers at least a portion of the query and the selected APIs together prepare the response optimized for the device according to the context data. The plan is provided to an execution component to execute the plan using the selected APIs and send the response to the requesting device.

  • Patent number: 11062312
    Abstract: The disclosure generally describes computer-implemented methods, software, and systems, including a method for placing a card into a usable state. A biometric input is received for a user to which a card has been issued by an entity. The card has an operational mode of an unusable state that has been previously identified by the entity for a particular PAN. The particular PAN is invalidated for use in further data exchanges using the card. The biometric input is received by an electronic controller embedded in the card. A determination is made that the biometric input matches one of one or more stored biometric profiles of users authorized to use the card. Based on the determining, a new PAN is activated for the card. The new PAN is usable in further data exchanges of the card. The operational mode of the card is modified to a usable state by the electronic controller.

  • Publication number: 20210176244
    Abstract: The disclosed exemplary embodiments include computer-implemented devices, apparatuses, and processes that, among other things, perform dynamic biometric authentication based on distributed ledger data. For example, a device may compute a first hash value based on first biometric data captured by a sensor unit, and may transmit a request to, and receive a response from, a computing system across a communications network via the communications unit. The request may cause the computing system to execute instructions maintained within the distributed ledger data, and to extract second biometric data maintained within an element of the distributed ledger data. The second biometric data may include a second hash, which the computing system may incorporate into the response. The device may authenticate an identity associated with the device when the first hash value corresponds to the second hash value incorporated within the response.

  • Publication number: 20210075791
    Abstract: The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that dynamically manage consent, permissioning, and trust between computing systems and unrelated, third-party applications operating within a computing environment. By way of example, the apparatus may receive a request for an element of data that includes an access token and first credential data associated with an application program. When the first credential data corresponds to second credential data associated with the application program, may determine that the requested data element is accessible to the application program and perform operations that validate the access token. Further, and based on the validation of the access token, that apparatus may obtain and encrypt the requested data element, and may transmit the encrypted data element to a device via the communications interface.

  • Publication number: 20210036854
    Abstract: The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that dynamically implement and manage hash-based consent and permissioning protocols. By way of example, an apparatus may obtain consent data that identifies one or more elements of data accessible to an application program executed by a device. The apparatus may generate a consent document for the application program based on at least a portion of the consent data, and may compute a consent hash value representative of the consent document. The apparatus may also generate and transmit permissioning data that includes at least the consent hash value to the device. The permissioning data may, for example, include information that instructs the executed application program to store the consent hash value within a local memory of the device and to associate the consent hash value with an access token of the executed application program.
