A cancellable and fuzzy fingerprint scheme for mobile computing security

Fingerprint recognition provides an effective user authentication solution for mobile computing systems. However, as a fingerprint template protection scheme, fingerprint fuzzy vault is subject to cross-matching attacks, since the same finger might be registered for various applications. In this paper, we propose a fingerprint-based biometric security scheme named the cancellable and fuzzy fingerprint scheme, which combines a cancellable non-linear transformation with the client/server version of fuzzy vault, to address the cross-matching attack in a mobile computing system. Experimental results demonstrate that our scheme can provide reliable and secure protection to the mobile computing system while achieving an acceptable matching performance.
