In this paper, we propose an efficient biometric-based remote user authentication scheme using smart cards, in which the computation cost is relatively low compared with other related schemes. The security of the proposed scheme is based on the one-way hash function, biometrics verification and smart card. Moreover, the proposed scheme enables the user to change their passwords freely and provides mutual authentication between the users and the remote server. In addition, many remote authentication schemes use timestamps to resist replay attacks. Therefore, synchronized clock is required between the user and the remote server. In our scheme, it does not require synchronized clocks between two entities because we use random numbers in place of timestamps.
