Analysis of Fingerprint Pores for Vitality Detection

Spoofing is an open-issue for fingerprint recognition systems. It consists in submitting an artificial fingerprint replica from a genuine user. Current sensors provide an image which is then processed as a “true” fingerprint. Recently, the so-called 3rd-level features, namely, pores, which are visible in high-definition fingerprint images, have been used for matching. In this paper, we propose to analyse pores location for characterizing the “liveness” of fingerprints. Experimental results on a large dataset of spoofed and live fingerprints show the benefits of the proposed approach.
