Irreversible fingerprint template using Minutiae Relation Code with Bloom Filter

Abstract

Template protected fingerprint authentication techniques have been proposed, which enables to create an irreversible fingerprint template. In this paper, we propose a new irreversible template creation technique using Minutiae Relation Code(MRC) which can describe the minutiae information efficiently, and Bloom Filter which can realize the irreversibility feature. We evaluate the authentication accuracy and security factors such as Shannon Entropy and the number of attack possibilities using FVC2002 and FVC2004 DBs. As a result, our proposed method can achieve 1.8% EER in FVC2002 DB2 with 249 attack possibilities.
