Abstract:

The traditional method of the secret image sharing generates the noise-like image,which can attract the hacker's attention easily.To solve this problem,a method of creating the meaningful share image is proposed in this paper.Comparing similarity of the images,we obtain the mosaic images sharing the secret image into the target images.Then,the complete shadow images can be generated after hiding the position sequence of the image blocks into the mosaic images by the reversible information hiding technology.The shadow images obtained by the proposed scheme can avoid the attention of the attacker as well as restore the lossless secret image.
