Enhancing Security for JPEG Image Against Mosaic Attack Using Inter-Block Shuffle Encryption
Inter-block shuffle has been proved to be able to enhance the security for JPEG image encryption. However, it does not change the numbers of non-zero coefficients in 8*8 blocks. This leads to information leakage. In this paper, the defects of inter-block shuffle are analyzed. An attack scheme is dev...
