| Abstract: | Image scrambling is a common method in information holding and safety transferring.Now many methods think they are of high safeties and can resist kinds of the attacks.Image scrambling degree is a method to evaluate the advantage and disadvantage of a image scrambling algorithm.The higher the image scrambling degree is,the more efficient the image scrambling algorithm is.Here various image scrambling algorithms are summarized into five classes.They are introduced in this paper and their advantages are illum... |
