A watermarking scheme able to resist geometric attacks is presented in this paper. The watermark embedding and detection are performed in a domain which is invariant to geometric attacks such as rotation, scaling and translation. The invariant domain is derived by applying a new generalized Radon transform to the image. The ability of the proposed method to withstand geometric attacks is evaluated experimentally.
