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. © 2014 IEEE.

In this paper, we share our recent work related to Radio Frequency Identification (RFID) sensor network with readers. The work mainly focus on the protocol for network system to perform the task of autonomous decentralized data distribution with consideration of economic and low-power RFID-sensor module scheme. We analyzed data pitfall in distributed RFID-sensor network, revealing the reason lies in the phenomenon. A distributed solution to tackle the problem has been designed in a simple way. The test results show that the system with proposed approach provides an efficient and more balanced in data distribution which proves the protocol is feasible for the application scenario.

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.
