Research on Image Scrambling Algorithm Based on Wavelet Transformation
Scrambling and gray-level spreading are two methods of image scrambling.whose aim is both to make the scrambled image unrecognizable.In this paper,two scrambling and spreading algorithms are proposed which are wavelet-based scrambling,spreading algorithm and local area single point spreading algorithm.These algorithms change not only the points’position but also the gray value.The experimental results show that these algorithms have good scrambling elrect and security.as well as strong anti.attack ability.
