Fingerprint authentication system for smart cards

Abstract

Among the several methods that enable fingerprint authentication of card holders, the one that executes the matching process on the smart card chip is the most important. The Pattern matching method, such as [1], is of no use for smart cards, because it takes too much time to adjust the position between the input image and template image. So we have developed an algorithm (FTA: Free Turning Algorithm) using minutiae that does not need the position correcting process. In this paper, we describe the basic effectiveness of this algorithm and a prototype system that implements it on a smart card. © 2002 Kluwer Academic Publishers.
