Study of Cancelable Biometrics in Security Improvement of Biometric Authentication System

Abstract

Part 8: ICBAKE 2015 WorkshopInternational audienceRecently, 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

Privacy-Preserving Sensor-Based Continuous Authentication and User Profiling: A Review

“…This improves the security level by enabling the use of several disrupted templates, all of them associated with the same biometric information, but may reduce the performance of the authentication system [ 87 ]. Cancelable biometrics are usually divided into two categories [ 84 , 88 ]: Salting : An invertible transformation is used to alter the features, hence being possible to recuperate the original information; Non-invertible : The distortions are produced with an irreversible function, which imply better diversity and revocability than salting methods. Biometric Cryptosystems : In these systems, the biometric information is encrypted or a cryptographic key is associated or directly generated from biometric features [ 84 , 89 , 90 ]: Key binding : The biometric features and an owner-chosen key are combined in the enrollment phase to generate a secure template or helper data via a trusted bit-replacement algorithm.…”

A Study of Cancelable Biometrics in the Security Improvement of Biometric Authentication System using Fault Tree Analysis

“…We assumed that basic events such as liveness detection, encryption, and cancelable biometrics, were used and provided the probability of occurrence of each event. Based on those probabilities, we calculated the probability of occurrence of the threat [18,19]. Table 4 shows the probability of occurrence of the basic events used in this analysis.…”
