US Patent 11907346 Facial feature analysis for authentication

Systems and methods may generally be used to authenticate a user. An example method may include capturing an image of a portion of a face of a user, retrieving, based on identification information, a registered model of the face from a database, and comparing the portion of the face in the captured image to a facial feature of the registered model. In response to determining that the portion of the captured image matches the facial feature of the registered model, the method may include granting access to secure content.
