Abstract

This paper proposed an integrated image compression and encryption technique using similiar to color cell compression techniques with Secure Hash Algorithm 256 .The purpose of image compression is to represent images with less data in order to save storage costs or transmission time with secure. Digital images, which covers the high percentage of the multimedia data, its protection is very important. It designed a lossy compression that exploits the pixel redundancy and visual imperceptibility of human eye to fine details in the digital image. This can be achieved by image Compression process, to reduce the pixel and visual redundancy, adjacent pixels can be used to only stores RGB colour information in each pixel continuously .For encryption ,using secure hash functions the bit length of the digest they produce 256 bit message for the purpose of security for transmitting digital image.
