摘要：

This paper is aimed at the image encryption scheme applicable to JPEG2000 codec. Firstly, two chaotic maps are suggested and their statistic characteristics are also analyzed Secondly, to accomplish a controllable visual effect of encrypted image, a visual quality control model is presented, and on the basis of which, a chaotic image encryption scheme is constructed by chaotically modulating the randomly selected approximate coefficients at the coarsest level in wavelet domain. Then, the security and efficiency of the algorithm are analyzed. Finally, the experiment results illustrate that the proposed algorithms are credible, secure, efficient, and practical for JPSEC.
