Abstract:
Templates used for a facial recognition process for authentication of a user to use a device may be updated by the device as features of the user change over time. Features of the user may gradually change over time due to changes such as facial hair changes, haircuts, gaining/losing weight, and/or aging. Updating the templates used for the facial recognition process may allow the user to continue being authenticated as features of the user change without the need for additional enrollments of the user.

Claim (Index 17):
A device, comprising:\n 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 a first image of the face of the 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 first image; \n compare the first feature vector to one or more reference templates stored in a first space in the memory of the device to obtain a first matching score; \n authorize the user to perform at least one operation on the device that requires authentication in response to the first matching score being above an unlock threshold for the device, \n store the first feature vector as a temporary template in a second space in the memory of the device in response to the first matching score being above a first threshold, wherein the first threshold is above the unlock threshold; \n obtain a second image of the face of the user using the camera; \n encode the second image to generate at least one second feature vector, wherein the second feature vector represents one or more facial features of the user in the second image; \n compare the second feature vector to the temporary template stored in the second space to obtain a second matching score; \n assess a confidence score for the temporary template by assessing if the second matching score is above a second threshold; and \n add the temporary template to the reference templates if the assessed confidence score is above a selected confidence score.
