With the development of information technology and network technology, thenetwork convergence has become a trend. With the network convergence forward, theopenness, combination and complexity continuously improve, not only previous securityproblem of Internet, TV network and telecommunication network will remains, but alsothe problem will be more serious on the platform of network convergence. The storage,reproduction and communication of digital multimedia become very convenient. Peoplecan edit, modify, copy and distribute digital music and digital image without limit, buthow to protect copyright and economic benefits and with which cause the problem ofpiracy and copyright disputes becomes increasingly serious social problem. Therefore, toprotect the copyright of multimedia content has become a urgent problem to be solved. Sothe digital watermark technology is a potential effective choice.Digital watermarking technology has been widely applied to digital multimediaworks of copyright protection, etc. But to present digital image watermarking technology,the watermark is usually hidden to the host image that is gray image. However, in real lifemost images is color image, so it can say the watermarking algorithm of color image ismore practical. And color image has more information than gray image, so the copyrightprotection is particularly important for color image.To summarizes the general framework and process of content supervision of networkconvergence. On this basis, with extant digital watermark technology, the paper design digitalwatermarking scheme in the content supervision of network convergence. The scheme is aimedat copyright protection of color image. Through the pretreatment of watermark and embeddingand extraction, the system can protect the copyright of color image.Through theoretical analysis and experimental results, system solution shows that thescheme has robustness and lowly complexity, strong practicability.
