Patent attributes
An authentication process is activated by a processor receiving an access request for user access to a user device. One or more biometric sensor module captures imaging data or other sensor data within a field of view encompassing the head of the user, or encompassing a head region including the head of the user. The processor carries out biometric recognition methods on the captured imaging data. Biometric recognition methods may include head-limb gesture recognition (including hand-to-face, and limb-near-head, gestures); head recognition; ocular recognition; facial recognition; and combinations of these methods. Upon successful match of captured sensor data with one or more user credential records stored for an authorized user of the user device, the processor authorizes the access request, providing access to the operating environment of the user device on start-up, or to one or more of a system setting, an application program, a data, and a hardware resource.
