In this paper a robust digital image watermarking method based on Discrete Fourier Transform is presented. For improving its robustness features in the algorithm the Error Correction Code is used. In order to improve the robustness with refer to geometrical attacks, an approach using a synchronization signal embedding is applied. For improving the algorithm efficiency the Radon Transform is applied. The method presented is tested by using standard example images and benchmarking software packages.
