Image information hiding scheme based on interweaving permutation

The existing image information hiding schemes have the shortcomings of insufficient embedding capacity and weak robustness, which are the key factors restricting their development. In order to address this problem, this paper proposes an image information hiding scheme based on interleaving permutation. In the proposed scheme, the secret image is processed by using interleaving permutation firstly; and then the secret image after interleaving permutation are compressed by using differential pulse code modulation (DPCM). Finally, the compressed bits are embedded into the low bit-plane of the carrier image. Experimental results show that the proposed scheme significantly expands the embedding capacity in comparison with the existing image information hiding schemes.
