Abstract: Aspects of the present disclosure describe systems, methods, and structures for anti-spoofing 3D face reconstruction using infrared structured light that advantageously reconstructs 3D face structures for facial recognition and detect face surface material(s) such that human skin may be effectively distinguished from artifacts thereby providing additional security for facial recognition including immunity from 2D/3D print attacks including face masks and special make-ups.
