Abstract
A password-less method for authenticating a user includes capturing one or more images of a face of the user and comparing the one or more images with a previously collected face template. Randomly selected colored light and randomized blinking patterns are used to capture the images of the user. Such captured images are compared to previously collected face templates, thereby thwarting spoof attacks. A secret image, known only to the user and the device, is moved from one area of the display to another randomly selected area, using the movements of the user's head or face, thereby providing a Turing based challenge. Protected audio video path (PAVP) enabled devices and components are used to protect the challenge from malware attacks.
