A secure fingerprint matching technique

Abstract

In this paper, we propose a novel robust secure fingerprint matching technique, which is secure against side channel attacks. An algorithm based on the local structure of the minutiae is presented to match the fingerprints. The main contribution is the careful division of the fingerprint recognition system into two parts: a secure part and a non-secure part. Only the relative small secure part, which contains sensitive biometric template information, requires realization in specialized DPA-proof logic. The rest of the system is running on LEON, which is a regular embedded platform.
