Abstract
Aiming at the safe problem of image transmission,this paper presents an image scrambling algorithm based on bit-exclusive-or and chaotic maps.The algorithm does a bit-exclusive-or operation on each pixel with its prior one first and gets the preliminary scrambed image.Then uses the chaotic maps theory mess the preliminary scrambed image again,thereby the effect of image scrambling is improved again.The experimental results show that the algorithm not only is superior to several existing methods,such as Arnold,Hilbert,MSB or gray code,but also can be easily implemented.关键词
