Protecting innovative substance and licensed innovation in a computerized frame has turned out to be progressively troublesome as advances, for example, the web, broadband accessibility and versatile get to progress. It has become dynamically less demanding to duplicate, change and redistribute computerized media, bringing about incredible decreases in business benefits. Advanced watermarking is a method which has been proposed as a conceivable answer for address this issue. Computerized Watermarking is an innovation which is utilized to distinguish the maker, proprietor, merchant of a given video or picture by implanting copyright marks into the advanced substance. In this venture, a powerful watermarking method in light of Discrete Wavelet Transform (DWT) is utilized. In this method the inclusion and extraction of the watermark in the dim scale picture is observed to be powerful than other change procedures. The execution of the proposed calculation is investigated by two execution measures to be specific Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE). The proposed calculation is actualized utilizing MATLAB programming.
