Novel Complex Conjugate-Phase Transform Technique for Cancelable and Irrevocable Biometric Template Generation for Fingerprints
This paper introduces a novel method for cancellable and irrevocable biometric template generation. The proposed method named as complex conjugate phase transform takes the main components like bit shifted-phase, twin complex conjugate transpose and chaff point generation along with it. The strength of the proposed method is tested in different aspects such as cancelability, irrevocability and security. The performance of the same is also calculated in terms of time and space complexity; ROC analysis is also carried out. The proposed method achieves higher matching scores; and the experimental results show that the proposed complex conjugate phase transform is better in all the aspects of performance.
Keywords: Cancelability, Hermitian transpose, Irrevocability, Phase, Shifting.
