Image security using chaos and EZW compression

This paper deals with the image security along with compression. Here we have proposed an algorithm using chaos on EZW compression technique to provide security along with image compression. We had chosen chaos for image security due to its robustness to initial condition and mixing property. Our process of providing image security starts with compressing the image using EZW. The output sequence of EZW is converted to 2-D data and on this 2-D data we apply row and column scrambling algorithm based on chaos. In this paper we also discuss about part of EZW in providing additional security to image along with its main function of compression.
