Abstract :
This paper presents a new robust watermarking algorithm which could against Geometric Attack. This algorithm first inserts the watermark into the original image, and then construct a watermarking image feature description table (IFDT) by doing a serial of image operation, which including Harris corner detection, Delaunay trigonometry network generation and Hu invariant moments computation. With the help of IFDT, we can do geometric correction upon a geometric attacked image. Finally, the watermark can be extracted from the corrected image. Experimental results show that the proposed scheme is robust and secure against a wide range of geometric attacks.
