Study of Cancelable Biometrics in Security Improvement of Biometric Authentication System

Abstract

AbstractRecently, there is a widespread use of biometric authentication systems. This is because biometric systems have become open and large scale and enrolment and authentication systems are separate. Many methods have been proposed for cancelable biometrics technology in biometric systems. However, the security criterion in such is indefinite in cancelable biometrics technology. Moreover, there is still no work on the systematic study of the safety of biometric authentication systems. In this paper, we consider the cancelable biometric techniques from the perspective of the safety of the system. In addition, we also verify the effect on the security precaution of the liveness detection techniques using Fault Tree Analysis, a risk evaluation method about data protection and spoofing prevention techniques.KeywordsCancelable biometricsBiometricAuthentication system
