Digital information hiding technique has been widely used in various fields of life. When a digital image is hidden a lot of information, visual concealment will be significantly reduced, the robustness will be significantly weakened, to this end, hiding algorithm based on bit-plane and the information of HVS is proposed. The pixel position and gray scale are taken into account, First of alL according to the theory of the layered image, the secret image is stratified by bit-plane. The layers are scrambling, using improved Arnold transform algorithm, Then. use the cover image as the matching template, to match each bit plane and the cover image most significant bit plane, optimize the secret sequence. Significant reduction in the secret information reduced the space occupied by the embedding sequence. Then in accordance with the masking effect of to human visual system get the table of embedded depth, The secret information is embedded in layers. Simulation experiments show that the algorithm can meet the visual effects, further improve the embedding capacity, PSNR value of image steganography greater, and can effectively resist various attacks, also has better robustness. And can effectively resist various attacks, this algorithm has better robustness.
