Biometric authentication has attracted attention because it has different characteristics from passwords. Biometric inputs are analog data and have a fixed fluctuation. Digitization is one possible measure to cope with the problems. Widening the quantization in step-size fashion to discriminate a personal distance is another possible measure. This paper proposes a biometric authentication system integrating these two measures. As biometric data are private, they are encrypted and saved on a server. Even if the server is attacked and the data are leaked, the private information concerning the biometric data is kept secret.
