Abstract. This work proposes a novel approach to secure fingerprint scanners against the presentation of fake fingerprints. An odor sensor (electronic nose) is used to sample the odor signal and an ad-hoc algorithm allows to discriminate the finger skin odor from that of other materials such as latex, silicone or gelatin, usually employed to forge fake fingerprints. The experimental results confirm the effectiveness of the proposed approach.
The same research group developed, in parallel with the skin elasticity method, a liveness detection procedure based on the corporal odor. REF use a chemical sensor to discriminate the skin odor from that of other materials such as latex, silicone or gelatin.
