Abstract

An encryption algorithm based on chaotic sequences ranking is presented aimed at the deficiency of the existing color image encryption method. Firstly the algorithm scrambles the position of color image and sets one-to-one relationship between the image matrix and chaotic sequence. Then the row and column of image matrix ranking were guided by the chaotic sequence ranking. On this basis, in order to improve privacy, the pixel value of the scrambled color image is shuffled. In this shuffling, the tricolor pixel values of each pixel in color image interchange guided by the chaotic sequence ranking, so realizing the color encryption. These results demonstrate that this algorithm has good encryption effect.
