  • Patent number: 12067558
    Abstract: A method for facilitating a transaction may include generating, via a token server computer, a token for use by a first entity computer, wherein the token is generated in response to a request received from the first entity computer. The method may also include transmitting, via the token server computer, the token to the first entity computer, wherein the first entity computer transmits the token to a second entity computer. The method may also include receiving, at the token server computer and from the first entity computer, data indicative of the second entity computer successfully receiving the token. The data may include a hashed value derived from at least the token, data indicative of an identity of the second entity computer, and writing, by the token server computer, the data indicative of the second entity computer successfully receiving the token to a registry.

  • Publication number: 20240143788
    Abstract: A method includes receiving, by a network processing computer, software information from a development computer. The network processing computer can determine one or more logical modules of a plurality of logical modules based on the software information. The network processing computer can provide the one or more logical modules to a testing computer. The testing computer evaluates one or more software modules corresponding to the software information using the one or more logical modules. The network processing computer receives a security evaluation report from the testing computer based on the evaluation of the one or more software modules using the one or more logical modules. The network processing computer creates a security evaluation summary based on the security evaluation report.

  • Publication number: 20240144280
    Abstract: Described herein is a system in which an electronic record is stored within a distributed environment. In this system, a validation node may receive a transaction record from an acceptance node. The validation node may verify that the acceptance node is authorized to participate in a blockchain network, identify a user associated with the transaction record, and append the transaction record to an electronic record. The transaction record may be associated with a digital signature formed by hashing multiple data elements, and then encrypting the hashed data elements using a private encryption key.

  • Publication number: 20190370549
    Abstract: A virtual reality (VR) device communicates with a projection display platform to establish a secure communication session related to an exchange of data. The session may be established using a QR code presented by the projection display platform that is received at the VR display. The VR device captures a voice or gesture related to the pending transaction and relays an appropriate instruction to the projection display platform for processing the pending transaction.
