Invisible Colour Image Watermarking Technique for Colour Images Using DWT and SVD

Recent popularity of social media and content sharing networks paired with fast Internet access has paved the way for mass multimedia content sharing on the Internet. As a result, volumes of sensitive data are been shared in various digital forms such that the risk of copyright infringements and misappropriations of digital content has grown at the same rate. In order to preserve copyright or authenticate digital content, digital watermarking has been considered as a viable solution for these problems. In the domain of digital watermarking, embedding a colour image as an invisible watermark to a colour cover image remain a challenge. As a solution to this problem, this paper presents such an invisible watermarking scheme based on DWT and SVD. The watermark created using the novel approach is experimentally shown to have the robustness, imperceptibility and capacity requirements.
