A New Method of Realizing Fingerprint Authentication on Smartcard

A new method of realizing fingerprint authentication on Smartcard has been presented. Based on SOC, this method puts the pre-processing algorithm, which is the most time-wasting process, out of card. It not only decreases the complexity of realizing fingerprint authentication on Smartcard, but also ensures the security of fingerprint information due to the original fingerprint image has been transformed with cryptography algorithm of this paper. The experimental results demonstrate that this method can shorten the time of fingerprint verification effectively.
