Fig - 1: Block diagram of CPE-MHCRDH Method  The encoding phase consists of four steps: the prediction  error detection, the image encryption, the 2 bit data hiding  by MSB substitution and compression as shown in fig 1
Fig - 2: Block diagram of EPE-MHCRDH Method  At the end of the process, the data embedded image  can decompressed and the embedded data can be extracted  without any errors and the clear image can be reconstructed  loss lessly by using MSB prediction as sh
