Abstract

To improve the embedding capacity of reversible data hiding in encrypted images(RDH-EI), this paper proposed an RDH-EI scheme based on adaptive MSB(most significant bit) and difference prediction. Firstly, it divided the image into blocks, and then performed block-level encryption and scrambling to resist the analysis of the encrypted image. In the stage of embedding data, it improved the method of adaptive MSB prediction. For the block without embedded data, the difference between pixels in some blocks was very small, this scheme adopted the method of adaptive difference prediction to embed data, and used the pixel in the upper left corner of the block as the target pixel to predict other pixels so as to make more embedded space. The experimental results show that the proposed scheme has reversibility and separability, and further improves the embedding capacity based on the adaptive MSB prediction method. For 512×512 grayscale images, the increased average embedded capacity is approximately 7 445 bit.
