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 15):
A method, comprising:\n determining whether a vein matching operation is to be operated on one or more images of a face of a user captured using a camera located on a device, the device comprising a computer processor and a memory; wherein determining whether the vein matching operation is to be operated comprises:\n generating a matching score by comparing a first feature vector for at least one feature in the face of the user in at least one captured image to at least one feature vector from a plurality of reference templates stored in the memory of the device tor an authorized user of the device; and \n determining the vein matching operation is to be operated in response to determining that the matching score is between a first unlock threshold and a second unlock threshold; \n wherein the vein matching operation comprises:\n comparing a feature vector for at least one vein in the face of the user in at least one additional captured image to at least one feature vector from a plurality of reference templates of vein features stored in the memory of the device for an authorized user of the device; \n determining whether the face of the user in the additional captured image is the authorized user for the device based on the comparison of the feature vector for the at least one vein and the at least one feature vector from the plurality of reference templates; and \n authenticating the user to use the device in response to determining the face of the user in the additional captured image is the authorized user for the device.
