Title: SYSTEMS AND METHODS FOR SPOOF DETECTION BASED ON LOCAL INTEREST POINT LOCATIONS
Abstract:
Disclosed are a system and method for performing spoof detection. The method includes: receiving, by processor from a biometric sensor, an input image of a biometric; obtaining, by the processor, keypoint locations of keypoints in the input image, wherein keypoints in the input image comprise local regions of interest in the input image; computing, by the processor, one or more anti-spoof metrics of the input image based on the keypoint locations; and, determining, by the processor, whether the input image is a replica of the biometric based on the one or more anti-spoof metrics.
