An asymmetric fingerprint matching algorithm for Java Card™

Abstract

A novel fingerprint matching algorithm is proposed in this paper. The algorithm is based on the minutiae local structures, that are invariant with respect to global transformations like translation and rotation. The match algorithm has been implemented inside a smartcard over the Java Card™ platform, meeting the individual's need for information privacy and the overall authentication procedure security. The main characteristic of the algorithm is to have an asymmetric behaviour, in respect to the execution time, between correct positive and negative matches. The performances in terms of authentication reliability and speed have been tested on some databases from the Fingerprint Verification Competition 2002 (FVC2002). Moreover, our procedure has shown better reliability results when compared with related Java Card™ algorithms. © Springer-Verlag Berlin Heidelberg 2005.
