Abstract: To prevent the leak of secrete information hidden in remote sensing image, a sample-based method for image inpainting was used in hiding secrete information in remote sensing image. The method selected the maximum region similar to secrete information image, and covered the secrete information block, thus hiding the secrete information. The method had not only strong invisibility, but also little influence on the use of remote sensing image. With reference to digital watermarking, whether users can see secrete information or not according to their authority status was realized, which facilitated the use of remote sensing image. Experimental results show that the method is feasible, and it improves the application security of remote sensing image.
