A new image scrambling algorithm

Image scrambling was not only a usual image encrypt method, but also a preprocessing of data watermark and image hiding. A new image scrambling algorithm based on wavelet transformation and queue transformation is proposed in this paper. Because the scrambling algorithm was done on the wavelet transformed image, the scrambling degree was better. Firstly, the original image was transformed into wavelet domain, and then the improved queue transform was done to the image in wavelet domain. It was turned out by experiment that the scrambling effect of this algorithm is better.
