| 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.

| Abstract: | The conflict between traditional DRM system and diversified demand of users is analyzed,the notion of D2RM and digital works subtenancy are proposed,the model of subtenancy spread is established,and some important problems in practice and the corre-sponding resolutions are discussed.Finally,a example based on D2RM 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. |
