Abstract: A method may involve obtaining a latent fingerprint on a surface, storing the latent fingerprint, obtaining a live fingerprint on the surface, and authenticating the live fingerprint based in part on the stored latent fingerprint and in part on previously-authenticated fingerprint data. The method may involve rejecting authentication of the live fingerprint as a potential spoof, if the live fingerprint matches the latent fingerprint under a relatively strict correlation test. The method may also involve, when the live fingerprint doesn't closely match the latent fingerprint, granting authentication of the live fingerprint if the live fingerprint matches the previously-authenticated fingerprint data under a relatively loose correlation test.

Abstract: An apparatus may include a cover layer, a layer of first metamaterial proximate (or in) the cover layer, a light source system configured for providing light to the layer of first metamaterial and a receiver system. The first metamaterial may include nanoparticles configured to create ultrasonic waves when illuminated by light. The receiver system may include an ultrasonic receiver system configured to receive ultrasonic waves reflected from a target object in contact with, or proximate, a surface of the cover layer. The control system may be configured to receive ultrasonic receiver signals from the ultrasonic receiver system corresponding to the ultrasonic waves reflected from the target object and to perform an authentication process and/or an imaging process that is based, at least in part, on the ultrasonic receiver signals.
