| Abstract: | This paper presents a novel algorithm for digital image scrambling with the security problem of image information as background.Firstly, this paper introduces the sensibility of digital image. Secondly, this paper presents an algorithm which is based on MSB and using the chaotic sequence of logistic disturbing the bit of pixel. At last, this paper discusses the security of this algorithm.The result of our experiment shows that the algorithm has good scrambling effect and lower computing complexity. |
