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 10):
A device, comprising:\n a computer processor; a memory; a camera; at least one illuminator providing infrared illumination; circuitry coupled to the camera and the illuminator, wherein the circuitry is configured to:\n obtain one or more first images of a face of a user using the camera; \n encode 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; \n generate 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; \n compare the first matching score to a first unlock threshold for the device and a second unlock threshold for the device, the first unlock threshold being below the second unlock threshold; \n wherein:\n if the first matching score is above the second unlock threshold, the user is authenticated to use the device; or \n if the first matching score is below the second unlock threshold and above the first unlock threshold, the circuitry is further configured to:\n encode at least one of the first 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 first image; \n generate 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; \n compare the second matching score to a third unlock threshold; and \n authenticate the user to use the device if the second matching score is above the third unlock threshold.
