This publication describes methods, techniques, and apparatuses, implemented on a computing device, directed at detecting spoof fingerprints. In aspects, the addition of a quarter-wave polarizer above an optical fingerprint sensor, along with the utilization of a machine-learned algorithm, can enable a computing device to distinguish a spoof fingerprint from an authentic fingerprint.
