This paper proposes an algorithm for secrete information hiding in remote sensing image based on different authorities and it is based on remote sensing image fusion and can achieve hiding to different degrees of the secrete information according to different authorities of users.Firstly,it segments and extracts the secrete information in the fused remote sensing image and according to different authorities produces the disguised images in which the secrete information to different degrees is presented.Then it exploits singular value division(SVD) algorithm to embed the secrete sub-image imperceptibly into the disguised image to produce the disguised one in which secrete sub-image is hided.And experimental results show that this algorithm is not only quite transparent and has a good effect for large amount of secrete information hiding,but also has a strong robustness against such familiar image processes as JPEG lossy compression,noise adding,scaling,filtering,rotation and cropping.
