摘要：

In this paper, a method for digital image watermarking is described that is resistant to geometric transformations. A private key, which allows a very large number of watermarks, determines the watermark, which is embedded on a ring in the DFT domain. The watermark possesses circular symmetry. Correlation is used for watermark detection. The original image is not required in detection. The proposed method is resistant to JPEG compression, filtering, noise addition, scaling, translation, cropping, rotation, printing and rescanning. Experimental results prove the robustness of this method against the aforementioned attacks.
