Abstract

This paper proposes an adaptive registration pattern based fingerprint matching method dealing with the non-linear deformations in fingerprint The “registration pattern” between two fingerprints is the optimal registration of every part of one fingerprint with respect to the other fingerprint Registration patterns generated from imposter's matching attempts are different from those patterns from genuine matching attempts, although they share some similarities in the aspect of minutiae In this paper, we combine minutiae, associate ridges and orientation fields to determine the registration pattern between two fingerprints and match them The proposed matching scheme has two stages An offline, training stage, derives a genuine registration pattern base from a set of genuine matching attempts Then, an online matching stage registers the two fingerprints and determines the registration pattern A further fine matching is conducted In addition, the block orientation field is used as the global feature of a fingerprint to improve the performance of this method And 2nd and 3rd relational structures between minutiae are applied to promote the fingerprint matching method Experimental results evaluated by FVC2004 demonstrate that the proposed algorithm is an accurate one.
