Abstract

This paper proposes a (n, n) secret image sharing scheme based on array scrambling and rearrange operation. In this scheme the size of each generated shadow image is much smaller than the secret image. Less shadow size is more convenient for storage, transmission and hiding. This scheme can be directly applied on binary and gray scale images and can easily be extended on color images. This method can reconstruct the secret image precisely. Experimental results prove the efficiency of this scheme.
