Abstract:
Subepidermal imaging of a face may be used to assess subepidermal features such as blood vessels (e.g., veins) when the device is attempting to authenticate a user in a facial recognition authentication process. Assessment of the subepidermal features may be used to distinguish between users that have closely related facial features (e.g., siblings or twins) in situations where the facial recognition authentication process has less certainty in a decision about recognition of the user's face as an authorized user.

Claim (Index 1):
A method, comprising:\n obtaining one or more first images of a face of a user using a camera located on a device, the device comprising a computer processor and a memory; encoding the first image to generate at least one first feature vector, wherein the first feature vector represents one or more facial features of the user in the encoded first image; generating a first matching score by comparing the at least one first feature vector to a plurality of reference templates stored in the memory of the device; comparing the first matching score to a first unlock threshold for the device; in response to the first matching score being above the first unlock threshold, comparing the first matching score to a second unlock threshold tor the device, the second unlock threshold being above the first unlock threshold; in response to the first matching score being below the second unlock threshold, obtaining one or more second images of the face of the user using the camera: encoding at least one of the second images to generate at least one second feature vector, wherein the second feature vector represents at least one vein feature of the user in the encoded second image; generating a second matching score by comparing the at least one second feature vector to at least one vein reference template for the at least one region of the face of the user, the at least one vein reference template being stored in the memory of the device; comparing the second matching score to a third unlock threshold for the device; and authenticating the user to use the device in response to the second matching scores being above the third unlock threshold.
