Recently biometric authentication systems have become open and large scale thus leading to its widespread use. However, no systematic study has been done with regards to the safety of such systems. On the other hand, cancelable biometrics, the intentional distortion of biometric characteristics to protect sensitive data in biometric authentication systems, has been widely studied. Many methods have been proposed for cancelable biometrics technology, but the security criterion in such is indefinite. In this paper, we consider cancelable biometric techniques from the perspective of the safety of the system. We also verify the effect of the security precaution of the liveness detection techniques using Fault Tree Analysis, a risk evaluation method about data protection and spoofing prevention techniques.

This paper presents what the authors call the 'divergence problem' regarding choosing between different future possibilities. As is discussed in the first half, the central issue of the problem is the difficulty of temporally locating the 'active cause' on the modal divergent diagram. In the second half of this paper, we discuss the 'second-person freedom' which is, strictly, neither compatibilist negative freedom nor incompatibilist positive freedom. The divergence problem leads us to two hypothetical views (i.e. the view of single-line determination and that of one-off chance), and these views bring humans closer to the afree side - i.e. outside of the contrast between being free and being unfree. The afree side is greatly different from the ordinary human side. This paper tries to secure the second-person freedom as a substitute for the ordinary human freedom while preventing the divergence problem from arising.
