%X In order to improve the capacity and robustness of the image information hiding, the spatial information hi ding algorithm based on most significant bit (MSI3) and human visual system (HVS) was proposed. Firstly the secret information and the most significant bit plane were matched and replaced to reduce the capacity of the embedded infor- mation, and new secret information was formed. Then according to the different degrees of redundancy of the human visual for texture areas and smooth areas, high gray areas and low gray areas of images, the information was embedded. hhe experimental results show that the algorithm has better robustness and the embedding capacity is greater than the LSI3 algorithm,and that the PSNR value of stego images is greater than 38dI3 to maintain good visual effect.
