Can Cancelable Biometrics Contribute to the Security Improvement of Biometric Authentication Systems?

Abstract

Cancelable biometrics techniques are considered from the viewpoint of data protection in authentication systems. Though various methods are proposed for this technology, the security criterion is indefinite. Moreover, there is still no work on the systematic study of the safety of biometric authentication systems. In this paper, cancelable biometric techniques are considered from the perspective of the safety of the system. Furthermore, the effect on the security precaution of the liveness detection techniques is verified by using Fault Tree Analysis, a risk evaluation method about data protection and spoofing prevention techniques.
