Lossless Information Hiding Scheme Based on Neighboring Correlation

A lossless information hiding scheme based on neighboring correlation is proposed in this paper. The scheme hides secret information into gray-level images according to the correlation between neighboring pixels. The performance of the proposed scheme has been evaluated in terms of payload capacity, image distortion, as well as embedding rate, and the experimental results show that the proposed lossless information scheme is capable of providing a great payload capacity without causing noticeable distortion, and the embedding rate is quite high. In addition, the proposed scheme can completely restore the host image after secret data extraction.
