In earlier methods, image encryption is done before image compression. Implementing this kind of method for designing algorithms for both encryption and compression is a complex and time-consuming process. In this project we design an efficient image encryption-then-compression system, where loss-less compression is considered. The proposed image encryption scheme operates in the prediction error domain to provide a high level of security. In this technique, we use arithmetic coding in order to compress of encrypted images efficiently. We also measure image properties such as mean square error, normalized mean square error and root mean square error values to compare the performance with previous methods.
