Abstract

Research in information hiding has grown explosively. However, many questions still exist concerning the potential of the technology and its role in establishing and upholding intellectual property rights in the digital age. This work, provides an overview of information hiding, outlining its main disciplines (covert channels, steganography [1], digital watermarking, and anonymity), and some applications current driving interest. The focus is on the current status of and prospects for digital watermarking [2], devoting special attention to a taxonomy based on insertion domain, applicability, and types of existing algorithms. In this paper, a method is presented, to apply existing watermarking embedding and recovering techniques applied on extracted video frames, to cater the digital watermarking needs of the world by concentrating on embedding the watermarks in the R-G-B planes of colour images. For intellectual property right protection of multimedia images, the colour image is watermarked three times by embedding the same watermark in each plane of multimedia image. Multimedia images are divided into R-G-B colour planes and watermarks are inserted into the individual colour planes. One or more watermarks can be inserted into one or more of the colour planes. The authentication process consists of retrieving the watermarks from all the three colour planes and a final watermark is constructed from the intersection of all the retrieved watermarks. The proposed work has been implemented in both spatial domain and transform domain. For spatial domain, threshold-based correlation watermarking scheme is used whereas, for transform domain DCT based watermarking is done.
