This paper considers a situation where the copyright of distributed images/photos is violated. Since the images/photos published on social networks or any networks are usually modified and/or compressed to the match the template provided by the service providers, this paper propose a digital image watermarking based on DWT coefficients modification to be used for such images/photos. Basically, there are two parts in the image processing, in the embedding process, the blue component of original host image is decomposed by the Discrete Wavelet Transform (DWT). Then image is transmitted. At the receiver end, original components of the watermark image are extracted by using adaptive mean filter.
