In recent days transmitting digital media having large size data through the internet became simple task but providing security and security became big issue these days. Using pseudorandom permutation, image encryption is obtained. Confidentiality and access control is done by encryption. Image encryption has to be conducted prior to image compression. In this paper, how to design a pair of image encryption and compression algorithms such that compressing encrypted images can still be efficiently performed. This paper introduced a highly efficient image Encryption-Then Compression (ETC) system.
