On the Vulnerability of Fingerprint Verification Systems to Fake Fingerprints Attacks

A new method to generate gummy fingers is presented. A medium-size fake fingerprint database is described and two different fingerprint verification systems are evaluated on it. Three different scenarios are considered in the experiments, namely: enrollment and test with real fingerprints, enrollment and test with fake fingerprints, and enrollment with real fingerprints and test with fake fingerprints. Results for optical and thermal sweeping sensors are given. Both systems are shown to be vulnerable to direct attacks
