摘要：Nowadays there is development in the multimedia and network technologies. That’s why the privacy and security becomes the major issues since the multimedia is transmitted openly over the network .so that Along with privacy and security, the space of s storage is also an important point that can’t be missed. So that, provide the privacy and security to the multimedia, encryption work as the similarly of root to reduce the storage space compression can be used. Reduction size also reducing the time taken for transmission. In many practical experiments, image encryption to be conducted prior to image compression. This has to be the problem, how to design a pair of image encryption and compression algorithms such that compressing the encrypted images can still be efficiently performed. In this research work, we design the algorithm and implement an efficient image encryption - compression system. The proposed image encryption method is operated with random permutation method which is shown to be providing reasonably high level of security. We also have implement the new kind of image compression algorithm using Haar and Daubechies Wavelet Transform can be used to efficiently compress the encrypted image. Moreover, the compression approach applied to encrypted image is proved more efficient in terms of Compression Ratio (CR), Mean Square Error (MSE), Peak Signal to Noise Ratio (PSNR). For the implementation of this proposed work we use the Image Processing Toolbox under MATLAB software.
