A Novel Irreversible Transformation Scheme for Biometric Template Protection
Modern biometric technologies claim to provide alternative solution to traditional authentication processes. Even though there are various advantages of biometric process, it is vulnerable to attacks which can decline its security. In this paper, the authors propose a novel Irreversible Transformation Scheme (ITS) to secure biometric templates based on chaotic maps which are known to possess desirable properties of pseudo randomness, high sensitivity to initial conditions and very large key space. The simulation and analysis results shows that the proposed chaos based ITS is computationally simple compared to standard traditional cryptographic algorithms and provides better security performance.
