Abstract

The rapid development of techniques requires fast and secure transmission of images through the network. Traditional way of secure transmission is, to encrypt the compressed images. Even if this meets security prerequisites, this situation may be reversed. Therefore, an efficient image encryption then compression system (ETC) in prediction error domain is introduced. In this system, image is encrypted by calculating the prediction error of each pixel followed by encoding techniques. The encoding is done by simple arithmetic coding method. Simulation results shows that bit rate can be reduced to 12.
