Abstract
This paper proposes a new image watermarking scheme using the set of Tchebichef moments. The watermark is constructed as an independent identically distributed (i.i.d) Gaussian random vector that is imperceptibly inserted in a spread-spectrum-like fashion into the perceptually significant spectral components of the data. The watermark is robust to distortion caused by JPEG coding, dithering and image scaling. Experimental results are provided to support these claims.
