Enhanced Multi Secret Image Sharing Scheme for Gray and RGB Images

In this paper we proposed a Multi Secret Image Sharing scheme, multi secret image sharing means making multiple shares with multiple secrets such that each share contains the information of all secrets. The proposed algorithm improves the randomness of shares and takes less computation time than the existing one proposed by Chien-Chang Chen and Wei-Jie Wu. Our proposed algorithm uses bit reverse function along with XOR operation to generate shares and to reconstruct the secrets. Experimental results show that this algorithm takes less computation time so that it can be also performed on color images.
