  • Patent number: 11604899
    Abstract: The present disclosure involves systems, software, and computer implemented methods for providing user interface (UI)-based modifications to adjust and interact with data exchange splits. An example client device can include can identify a data exchange (DE) associated with at least three entities, the DE associated with a total value. A visualization representing the DE can be presented via a UI and can include a chart comprising the total value of the DE exchange divided into value areas that are each associated with a particular entity. In response to a detection of input associated with a selection of an edge between a first and second value area, the combined value area associated with the first and second value areas can be locked. In response to detected movement input associated with the edge, the relative values of the first and second inside the combined value area can be adjusted in the visualization.

  • Publication number: 20220360446
    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.

  • Patent number: 11483157
    Abstract: The disclosed embodiments include processes that manage a cryptographically secure generation and exchange of data between network-connected systems operating within a computing environment using a permissioned distributed ledger. For example, and based on secure interaction with a distributed smart contract maintained within ledger blocks of the permissioned distributed ledger, an apparatus and a counterparty system may generate local symmetric encryption keys that facilitate a secure communication session between the apparatus and the counterparty system. Using the symmetric encryption key, the apparatus may generate a cryptographically secure representation of generated or obtained data, which may be transmitted to the counterparty system across the secure communications channel.

  • Publication number: 20220263814
    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.
