Despite its importance, a few works have been proposed for fingerprint vitality detection. In this paper, we propose a novel feature for detecting the "liveness" of fingerprint images. This feature is derived from the image power spectrum, and point out the difference between "live " and "fake" images in terms of high frequency information loss.

Abstract
Despite its importance, a few works have been proposed for fingerprint vitality detection. In this paper, we propose a novel feature for detecting the "liveness" of fingerprint images. This feature is derived from the image power spectrum, and point out the difference between "live " and "fake" images in terms of high frequency information loss. Preliminary results on a large data set show the effectiveness of the proposed measure.
