碩士 === 國立清華大學 === 資訊系統與應用研究所 === 93 === Ever since the prevalence of Peer-to-Peer (P2P) file sharing technology over the Internet, it is more convenient for users to share and transmit information directly, especially in media digital contents. However, the characteristics of digital content are easy to be obtained, duplicated, and distributed through the network. When the use of digital content allows immense opportunities for creators, the ability for anyone to make perfect copies and the ease by which those copies can be distributed also facilitate misuse, illegal copying and distribution, plagiarism, and misappropriation. These illegal behaviors potentially impact creators to hesitate to publish their digital content creation. Popular Internet software based on a peer-to-peer (P2P) architecture (such as Napster, Gnutella, KaZaA, and eDonkey) has been used to share copyrighted music, movies, software, and other materials. Thus, the protection of IPR for network creators has become an emerging issue on Peer-to-Peer network. There is a great desire for an effective and practical system that can preserve the economic value of digital content and protect the rights of the owners. In view of this, we present a right-protected digital content sharing system on Peer-to-Peer (P2P) network and utilizing Digital Rights Management (DRM) concept. The purpose is to allow creators can make profit from sharing digital content. Our proposed system can not only protect the rights of digital content from being used illegally, but also resist several attacks during transmitting process between peers and the server. It retains useful properties as those in Conrado et al.’s system, corrects its drawbacks and provides stronger security considerations including secrecy, Authentication, Integrity, and Non-repudiation. We expect the proposed system will become popular for more and more creators to share and spread their ideas.
