A REVIEW PAPER ON A SECURE IMAGE ENCRYPTION-THEN COMPRESSION SYSTEM USING WAVELET VIA PREDICTION ERROR CLUSTERING AND RANDOM PERMUTATION

Images can be encrypted in many ways; several techniques have used different encryption methods. In this research, we apply a new modified International Data Encryption Algorithm to encrypt the full image in an efficient secure manner, after encryption the original file will be compressed and we get compressed image. This paper introduced a highly efficient image encryption-then compression (ETC) system using wavelet. The proposed image encryption scheme operated in the prediction error domain is able to provide a reasonably high level of security. More notably, the proposed compression approach applied to encrypted images is only slightly worse, unencrypted images as inputs. The proposed image encryption scheme operated in the prediction error domain is shown to be able to provide a reasonably high level of security. We also demonstrate that an arithmetic coding-based approach can be exploited to efficiently compress the encrypted images. More notably, the proposed compression approach applied to encrypted images is only slightly worse, in terms of compression efficiency, than the state-of-the-art lossless/lossy image coders, which take original, unencrypted images as inputs. In contrast, most of the existing ETC solutions induce significant penalty on the compression efficiency. For the implementation of this proposed work we use the Image Processing Toolbox under Matlab software.
