Abstract


In the age of digital information, digital multimedia content protection objects, including text, images, audio, video, and other various media. Easy to copy, distribute and features such as digital media has, with the help of digital technology and the Internet random bulk copy and distribution of digital media products and content protected by intellectual property is widespread. This has bred a lot of pirated and does not regulate the use of multiple injuries caused by the behavior of our economic, social and cultural, and digital rights management system came into being. Digital rights management system through a series of technical means of digital content description, identification, trading, protection, monitoring and tracking, so that the digital content from production to distribution, from sales to the use of the entire content of the process of circulation in protection the state to protect the interests of relevant interests. Digital rights management systems based encryption technology from the early to the first generation of development to the present, has been integrated into a number of related technologies, such as digital watermarking, rights management technology, as well as identity authentication and so on. This article-depth analysis of the existing digital copyright protection technology, standards and systems, to build a digital rights management system based on the scrambling encryption and digital watermarking technology combined platform model, this model uses a the platform client \media formats of digital content uniformity of copyright protection and management. Digital content, whether online or offline, this model can ensure the safe use of digital content to prevent illegal copies of diffusion to provide copyright protection for digital content. The main research work are: 1) to understand the progress of the digital rights management research at home and abroad, in-depth study of a digital rights management system model theory and copyright protection technology, analysis of the traditional system model as well as the strengths and weaknesses of the existing system model. 2) on the basis of this theoretical study, building a digital rights management system platform model based scrambling encryption and digital watermarking. The platform uses the embedding the digital watermark in the digital content twice, bundled user hardware information and permission information, and finally on the digital data of the content scrambling encryption way to implement copyright protection for digital content. To effectively prevent the illegal use of the digital content, illegal copying of diffusion. 3) based on the build platform, design client software overall structure. The client software offline, the identity of the authenticated user permissions information for verification of digital content, playback of digital content. 4) a systematic study of the Visual C development environment, the client software. Users can log in through the client software platform site, open media files, instant browse files permissions.
