%X With the growing use of face recognition in security and video control domain, there is growing concern about the security and privacy of the biometrics data. Recently, technologies for biometric security and privacy have been proposed,which typically transform the biometric data to a binary string. hhese transformations can lead to some informalion loss and downgrade the performance of a system. This paper applied fuzzy logic to confirm the reliability of each bit in a binary string and to model the intra class variations. hhe experimental results show this method reduces the overlap of impostor distribution and genuine distribution and improves the performance of biometric security technology.
