  • BLOCKCHAIN ARCHITECTURE WITH RECORD SECURITY
    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.

  • AUGMENTED AND VIRTUAL REALITY OPERATIONS SYSTEM
    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.
