| With the rapid development of the Internet and computer technology, the streaming media technology in P2P networks receives an immense popularity. Meanwhile, the widespread use of Internet provides the streaming media business with a strong market force, which makes the business more and more popular. Up to the present, streaming media technology has been widely used in a wide variety of fields, including multimedia news releases, online live, online advertising, E-commerce, video on demand, remote education, telemedicine, Internet radio, real-time video conferencing and other aspects of Internet services, which brings a great convenience to everyday life.However, the development of streaming media technology is also confronted with the problem of digital copyright protection. The digital essence of streaming media makes it easy to be copied while P2P networks adopt that decentralized management approach that makes illegal replications much easier, which do harm to the legitimate interests of both the creator and the owner of media content. Therefore, researches on P2P-based streaming media copyright protection technologies have important theoretical significance and commercial value.In this thesis, we mainly address these problems above as follows. First, various details about digital copyright protection technologies, as well as P2P technology and streaming technology, are presented, based on which we propose a P2P streaming media-based copyright protection framework. The proposed framework separates media content and broadcast license, in which the media content is stored in streaming media server and the broadcast license is stored in DRM server. Content providers utilize streaming media packer to encrypt media files. The decryption passwords are stored in DRM server, which takes charge of both the generation and issuance of broadcast licenses for users. On the other hand, SN-C nodes are incorporated into the licensing process, which avoids that network operators reduce to pipeline provider and ensures the legitimate interests of the operator. |
