Combined Fingerprint Minutiae Template Generation for protection

Abstract

The primary purpose of using a biometric system is to provide non-reputable authentication. Authentication implies that (i) only legitimate or authorized users are able to access the physical or logical resources protected by the biometric system and (ii) impostors are prevented from accessing the protected resources. While a biometric system can be compromised in a number of ways, one of the potentially damaging attacks is the leakage of biometric template information. The leakage of this template information to unauthorized individuals constitutes a serious security and privacy threat. Therefore in this paper we propose a model of creating a combined minutiae template. By using the combined minutiae template, the complete minutiae feature of a single fingerprint will not be compromised when the database is stolen. The experimental results show that our system can achieve a very low error rate. Compared with the state-of-the-art technique, our work has the advantage in creating a better new virtual identity when the two different fingerprints are randomly chosen.
