| Abstract(in English) | Biometric authentication attracts much attention because of the reuse problem of IDs and passwords. Recently, privacy-preserving biometric authentication schemes in which authentication process is exectuted on encrypted biometric information by homomorphic-encryption have been proposed. In our previous work, we have shown a spoofing attack to arbitrary user and a recovery attack for template against a cancelable biometric authentication scheme based on homomorphic encryption proposed by Hattori et al. when a binary coding is used. In addition, we have also proposed a countermeasure to our attack. Furthermore, a spoofing attack to arbitrary user and a recovery attack for template against a cancelable biometric authentication scheme based on homomorphic encryption by Yasuda et al. have been proposed. In this paper, we consider about applicability of the proposed countermeasure which verifies whether a feature vector is a binary code or not to our attack against Hattori et al. scheme to Yasuda et al. scheme. As a result, it is difficult to apply the countermeasure to Yasuda et al. scheme. Then, we consider about new countermeasure that uses Xor masking, multiplicative masking and additive masking, respectively. |
