Abstract:
A method of host-directed illumination for verifying the validity of biometric data of a user is provided that includes capturing biometric data from a user with an authentication device during authentication and directing illumination of the biometric data from a host authentication system during the capturing operation. Moreover, the method includes comparing illumination characteristics of the captured biometric data against illumination characteristics expected to result from the directing operation, and determining that the user is a live user when the illumination characteristics of the captured biometric data match the illumination characteristics expected to result from the directing operation.

Claim (Index 1):
A method for detecting user liveness comprising:\n capturing, by a computing device, a sequence of discrete images of the face of a user while an illumination device included in the computing device turns on and off to apply illumination to the face of the user; transmitting over a network, by the computing device, the sequence of discrete images to an authentication computer system; recognizing, by the authentication computer system, reflections in a plurality of the images, the reflections resulting from the illumination applied during said capturing step; and determining, by the authentication computer system, the user is live when the reflections recognized in each image included in the plurality of images correspond to the illumination applied during said capturing step.
