Abstract :
In this paper we propose a novel method for watermarking. It uses the spatial and the discrete cosine transform (DCT) Domains. The proposed method deals with colored images in the biological color model, the Hue, Saturation, and Intensity (HSI). The method robustness is tested against several attacks. Watermark security is increased by using the Hadamard transform matrix. The watermarks used are meaningful, and of varying sizes.
