Evaluation of direct attacks to fingerprint verification systems
This addresses security risks in biometric authentication for users and systems, but appears incremental as it focuses on evaluating existing methods.
The study investigated vulnerabilities of fingerprint verification systems to direct attacks, evaluating two systems on real and fake fingerprints and deriving statistically significant observations on robustness.
The vulnerabilities of fingerprint-based recognition systems to direct attacks with and without the cooperation of the user are studied. Two different systems, one minutiae-based and one ridge feature-based, are evaluated on a database of real and fake fingerprints. Based on the fingerprint images quality and on the results achieved on different operational scenarios, we obtain a number of statistically significant observations regarding the robustness of the systems.
