Analysis of Scrambling Performance of Encrypted Image
Xu Jiang · 2006
With the rapidly development of network and multimedia technology,more and more image data transfer on Internet.In order to protect the privacy and to make the image data transfer more safely,a lot of schemes of image en- cryption are presented.To evaluate and analyze the scrambling perfermance and security of these schemes,some param- eters such as the percentage of unchanged point,the information entropy,the average of pixel values change and the self- correlation of image are given.The simulation results of the experiment indicate that these parameters can be effectively ued to evaluate scrambling performance and the security of encrypted image.
