This paper proposes a new watermarking scheme that is robust to geometrical attacks and can embed large user information. By inserting a template that is used for correcting geometrical distortions we can embed user information into an image affordably. We embed the user information using a base watermark (128x128 pixel size). If the base watermark is shift then the peak position of its cross-correlation with the watermarked image is also shift. Using this fact, our algorithm can embed large information. To extract user information we have to firstly extract the template. After restoring the watermarked image to the original state using the template, we can extract the embedded user information. The performance of the presented scheme is evaluated for various geometrical attacks and compression. Results show that the fact that the scheme is robust to geometrical distortions and effective to embed and extract large user information.
