Copyright risks in multimedia are increasing as a result of large numbers of computers in network. A technique used to preserve rights is watermark implementation to authenticate authorship. This information which is embedded in the original image is a “Digital Watermark”, which might be visible or invisible. For this technique to become more efficient, the Watermark should be robust so that its removal from the original image by the hackers becomes difficult. In time, various Watermarking algorithms are developed. However, each of them has its own advantages and limitations. Recent research shows that SVD (Singular Value Decomposition) algorithms are used because of their simple scheme and mathematical function. Another algorithm is DCT (Discrete Cosine Transform). Each of such algorithms has its own advantages, a combination of their advantages is the RST (Rotation, Scaling, Translation) algorithm. This paper shall attempt to compare algorithms and provide a conclusion on their performance and finally implementation in Hardware, in Xilinx Virtex II Pro
