摘要
通过分析传统DRM系统与用户多样化需求之间的矛盾,提出了D2RM和数字作品转借的概念,建立了转借传播模型,讨论了实现过程中的重要问题和解决方法。在D2RM的基础上设计了一个实例,通过推理,验证了方案的可行性和安全性,证明基于D2RM的数字作品转借方案是值得大力推广的。
The conflict between traditional DRM system and diversified demand of users is analyzed, the notion of D^2RM and digital works subtenancy are proposed, the model ofsubtenancy spread is established, and some important problems in practice and the corresponding resolutions are discussed. Finally, a example based on D^2RM is designed, the feasibility and security of the scheme is verified through ratiocination. It is proved that the scheme of digital works subtenancy is deserved to be entented.
