Thus it becomes important to protect personal information stored in the card. Verification of the card holder s identity using a fingerprint has advantages over the present practices of Personal Identification Numbers PINs and passwords. However the computational workload of fingerprint verification is much heavier than that of the typical PIN-based solution. In this paper we consider three strategies to implement fingerprint verification in a smart card environment and how to distribute the modules of fingerprint verification between the smart card and the card reader. We first evaluate the number of instructions of each step of a typical fingerprint verification algorithm and estimate the execution time of several cryptographic algorithms to guarantee the security privacy of the fingerprint data transmitted in the smart card with the client-server environment. Based on the evaluation results we analyze each scenario with respect to the .
