Abstract

According to the digital image in HSV space

an image encryption algorithm has been built based on3 D Feng chaotic mapping. If the original image is the RGB format

it should be converted to HSV space. And then

the truncated data sequence could be constructed in x

z three directions by Feng mapping. According to index of these three sequences

information of H

V three channels were scrambled. Experimental results show that the proposed method can obtain ideal encryption effect

and three directions relevance of encrypted image are all below 0. 01.
