- Abstract
In this paper, the information security issue on biometric data is studied. We introduce the development of biometric technology with its application in security systems and discuss the significance. Focusing on distribution in space domain and uniform diffusion in frequency domain, a compounded chaotic cipher strategy with dynamic Bernoulli mapping is proposed to improve the performance on cryptographic text with consideration both of volatility and correlation. Aiming at visual original biometric data, related tests and analysis on key space, sensitivity, correlation, and uniform distribution are performed with comparison to diverse schemes including triple data encryption standard algorithm and logistic mapping cipher. Experiments results show that the proposed approach possesses good secure performances on both random scrambling in space domain and uniform distribution in frequency domain. The cryptosystem can be implemented with basic computational operators and provides an efficient and sensitive key space scheme for biometric data protection. Copyright © 2014 John Wiley & Sons, Ltd.
