Cylindrical Curve for Contactless Fingerprint Template Securisation

Abstract

A large quantity of biometric models has rapidly proliferated in biometric applications. Due to the fact that biometric systems expose users to enormous risks that endanger , the authors improved an existing technics technique and adapted it to the contactless system. The proposed model, in this article, propose a very secure fingerprint model protection technique in which a cylindrical curve is generated as a user secure model for a contactless fingerprint. During the construction of our model, the authors use three invariants intra-personals characteristics, namely the set of distances between the detailed points and the center of mass, the orientation information of the detailed points and the number of endings between the minutiae points and the singular point. The results of the experimental analysis performed on the FVC databases(2000, 2002 and 2004) and the authors’ own database show a highly encouraging performance and present the viability of the proposed technique.
