Abstract :
A digital image watermarking system that takes advantage of the discrete Fourier transform properties to embed a spread spectrum watermark in an image is presented in this paper. Watermark robustness to translation, rotation and scaling attacks is achieved with the proposed system. A description of the method is included and results are presented
