Reversible Data Embedding Using the Sliding Window

Recently, many researchers have proposed reversible data embedding schemes in which payload can be added and extracted to digital multimedia. In this paper, we propose a reversible data embedding scheme with high payload capacity, low distortion, and improved image security. The experimental results show that our proposed scheme can embed one bit per pixel in the best case. The proposed scheme has greater payload capacity than Tian's and Celik et al.'s schemes. In addition, the visual quality and security of the stego image outperforms Thodi et al.'s scheme for a grayscale image.
