US Patent 11087572 Continuous authentication

Methods, devices, and systems are provided for providing continuous authentication to a user having a wearable device in an access control system. The wearable device allows the authentication of the user to be maintained until an authentication interruption signal is received. The interruption signal may be based on user biometrics, a state of the wearable device, a communication range of the wearable device with a trusted mobile device, and more. Upon receiving the interruption signal, the continuous authentication for the wearable device, and the user, may be revoked, destroyed, or disabled.
