  • Beacon spoofing prevention
    Patent number: 10171496
    Abstract: In one embodiment, a beacon signal is received from a beacon device. Either a mobile device or a server identifies a beacon authentication value from the beacon signal. Either the mobile device or the server calculates a local verification value from a security algorithm. A comparison of the authentication value to the local verification value is performed, and a location service is provided based on the comparison.

  • Group membership block chain
    Patent number: 10021080
    Abstract: A system and method for achieving authorization in confidential group communications in terms of an ordered list of data blocks representing a tamper-resistant chronological account of group membership updates. This method permits ad-hoc and decentralized group definition, dynamic and decentralized membership updates, open sharing, tamper resistance, and tracking of membership history. There are many applications of these techniques. One such application is enabling end-to-end encryption of instant messaging, content sharing, and streamed media.
