With the rapid growth of internet the various digital methods has been proposed to protect the multimedia information from the non-authorized accesses use and change. A novel method is proposed which deals with secure extraction of data by utilizing transform based image watermarking techniques. The conventional transforms are applied in an optimized mode in these schemes in different spatial regions of the image to embed a watermark. The scheme is subjected to Signal processing attacks and Geometric attack to test against the robustness of the image. The watermarking of image is made secure by testing against unauthorized detection techniques employed by attackers. This is realized by a correlation based detector applied to the scheme. Experimental results show that the watermarked image is robust and secure against Signal Processing attacks, Geometric attacks and unauthorized Detection attacks.
