An Image Hiding Scheme Based on Du´s Disk Allocation Method

In this paper, we discuss whether there is any possibility of applying declustering to design various image hiding schemes. To test our theory, we propose a novel image hiding scheme based on Du¿s disk allocation method, which is a typical declustering scheme, to hide binary secret images and gray scale secret images in a gray scale secret image. From the experimental results, we found that our scheme performs better than the simple LSB substitution method when the secret images are binary or the size of the gray scale is smaller than or equal to the gray scale host image.
