Abstract
Privacy of information is an important issue in modern era of information technology to manage handling of sensitive information over networks efficiently. It is seen that individual use of inversion and circular shifting while encryption of images does not provide adequate security and weaknesses remain can be exploited by interceptors. In this paper, we propose an improved encryption scheme which utilizes both inversion and shifting in specific manner. We use pseudo random number sequences to perform inversion and circular shifting in a random manner for transforming image pixels. Simulation results show that encrypted images obtained are quite unintelligible and pixels distributed uniformly. Also, proposed encryption method is error propagating, follows avalanche criteria, has large key space and provides higher information security.
