A Resistant Secret Sharing Scheme

In this paper, we proposed a novel (2, 2) secret sharing scheme applied for grayscale images. This scheme can produce two noise-like shared images that help avoid a secret image being grabbed. The construction phase of shared image consists of producing two shared images of the secret image by a (7, 4) Hamming code operation. To prevent attackers from forging shared images, a logo is embedded into the shared images first by using Tianpsilas reversible data embedding scheme. Later, the embedded secret image is shuffled by Torus automorphism to enhance its security. Experimental results show that the noise-like shared images can be successfully generated by our proposed scheme.
