WEARABLE DEVICES AND RELATED SYSTEMS FOR AUTHENTICATING A USER WITH SURFACE ELECTROMYOGRAM (sEMG)-SIGNALS

Abstract:

Before or after a first-type authentication has been completed, disclosed devices, systems, and methods may conduct a second-type authentication to authenticate a user such that the user can log into a secure device and/or access secure content. An example system may cause a wearable device to activate a biosensor, which extends along a full internal circumference of the wearable device when worn, to detect at least a first sEMG signal on the user's skin responsive to the user performing a first gesture. The system may also generate or receive a first user signature based on the first sEMG signal and determine whether the first user signature matches stored authentication training data. In response to determining that there is a match, the system may complete the second-type authentication to authenticate the user.
