Abstract: This paper proposes a method of digital watermarking algorithm based on DWT domain for secrete information hiding in remote sensing image. 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 little effect for the statistical property and use value of remote sensing image.
