However, how to handle the relevant privacy concerns remains to be troublesome. In this paper, we propose a novel security model to formalize the privacy con- cerns in biometric-based remote authentication schemes. Our security model covers a number of practical privacy concerns such as identity privacy and transaction anonymity, which have not been formally con- sidered in the literature. In addition, we propose a general biometric-based remote authentication scheme and prove its security in our security model
