  • Publication number: 20240126575
    Abstract: The disclosed embodiments include computer-implemented systems and processes that dynamically and selectively modify portions of a displayed interface to include interface elements that, when selected by a user through a single provided input, initiate a performance of a data exchange in accordance with parameter values consistent with prior initiated data exchanges. For example, a communications device may display, on a display unit, a first interface element representative of a first data exchange and may receive expected values of parameters that characterize the second data exchange. When a determined parameter value is consistent with the expected parameter values, the communications device may modify the first interface element and present, on the display unit, the modified first interface element and a second interface element within the interface.

  • Publication number: 20240097915
    Abstract: The disclosed embodiments include computer-implemented processes that, using a distributed notarized ledger, constrain an ability of multiple parties to simultaneously, or near simultaneously, update or modify elements of reference data maintained within a centralized data store. For example, an apparatus may receive, from a first computing system, a request to modify reference data maintained at a second computing system. The apparatus may approve the first requested modification to the reference data based on a notarization criterion maintained within an element of a notarized distributed ledger, and perform operations that record notarization data characterizing the approved modification within an additional element of the notarized distributed ledger. The apparatus may also transmit the notarization data to the first computing system, and the notarization data causing an application program executed by the first computing system to modify local reference data in accordance with the notarization data.

  • Patent number: 11790354
    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.

  • Patent number: 11755783
    Abstract: The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that manage cryptographically secure exchanges of data using a permissioned distributed ledger. For example, an apparatus obtains parameter values characterizing an exchange of data and transmits the parameter values to a first computing system, which executed instructions included within a distributed ledger. The executed additional instructions cause the first computing system to access rules data recorded onto the distributed ledger and establish a consistency between the parameter values and at least a portion of the accessed rules data. The apparatus receives, from the first computing system, confirmation data indicative of the established consistency, and based on the confirmation data, transmit a request to execute the data exchange in accordance with at least the portion of the parameter values to a second computing system.

  • Patent number: 11711362
    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.

  • Patent number: 11651100
    Abstract: A system, device and method for enforcing privacy during a communication session with a voice assistant are disclosed. Periodically during the communication session with the voice assistant, sensor data is acquired. The sensor data is processed to determine a number of persons present in an environment of the voice assistant. The communication of private data by the voice assistant is enabled when one person is in the environment and that person is the authorized user. The communication of private data by the voice assistant is disabled when one person is in the environment and that person is not the authorized user. When more than one person is present in the environment of the voice assistant, the communication of private data by the voice assistant may be enabled when the environment of the voice assistant is determined to match the one or more predetermined privacy criteria for a multi-person environment.
