Survey on Biometric Data Security and Chaotic Encryption Strategy with Bernoulli Mapping

This paper discusses the information security issue on biometric data. A brief survey is given at first with the discussion on the significance of biometric application. A novel encrypting strategy combined with Bernoulli-Logistic chaotic cipher system is proposed to improve the performance on cryptographic text with consideration both of volatility and correlation. Experimental results show that the proposed approach for encryption provides an efficient and more secure performance.
