There are several shortcomings with the traditional token based authentication using magnetic strip card with PIN/password protection such as easy to duplicate and from forgotten to stolen password etc. Fingerprint authentication is more secure and is a convenient replacement of PIN/password. With the advancement in the microprocessor technology for token such as smartcard and fingerprint authentication technology, token based fingerprint authentication becomes a viable alternative to replace the existing magnetic strip card with PIN/password protection. In this paper, an overview of the token-based fingerprint authentication will be given and a review of the recent publications and patents will be presented.
