摘要
版权保护一直是困扰创作者和发行商的重大问题,现有的技术和协议在防止盗版上都存在着一定程度的缺陷。数字版权管理(DRM)系统综合使用各种技术和协议寻求买卖双方的利益平衡,保证创作者的版权和用户端的安全。本文提出基于模块化实现DRM系统的全面解决方案。该实现方案对DRM模型进行了改进,将水印的嵌入移交给权威机构来处理,买卖双方只需对水印的存在性进行检验。最后,对整体安全性能进行了分析。该方案利用现有的技术和协议,实现了对作品的整个生命期的安全访问控制。
Copyright is disturbing the authors and issuers. DRaM system combines all kinds of techniques and protocols, so as to balance the benefits of the buyers and sellers, and to assure the authors＇ copyright and users＇ security. In this paper, the integrate implementation scheme based on the functional architecture for DRM is proposed. The DRM model is improved on relegating the work of implanting digital watermark to authoritative organization, so the buyers and sellers only need to check the presence of watermark. At last, the analysis about the security of the scheme is also given. Secure access control can be achieved in the writing＇s whole life period.
