| 中文摘要: |
| 针对现有的DRM(digital rights management)机制缺乏真正的责任描述和实施能力问题,提出一种应用于DRM的责任授权模型及其实施框架.该模型基于分布式时态逻辑和Active-U-Datalog语法规则,具有表达事件驱动、时间驱动和责任补偿等各类责任授权的语义能力,并具有良好的可实施性.对该模型的语法语义进行了分析和说明,描述了责任实施机制,并对该模型的实现、应用和表达力进行了说明和示例.该模型提高了DRM系统对数据使用控制的灵活性和能力. |
| 英文摘要: |
| Due to the absence of actual obligation description and implementation abilities in existing DRM (digital rights management) mechanism, this paper presents an obligation authorization model and its implementation framework that can be applied in DRM. The model is based on distributed temporal logic and Active-U-Datalog rules, which empowers the model to express event-driven, time-driven, obligation compensation and other semantics of obligation descriptions, and also give the model a favorable feasibility of implementation. The semantics and syntax of the model are analyzed and explained. And the implementation mechanism of the model is discussed. Finally, the implementation, application and expressiveness of the model are showed and illustrated. The model improves the flexibility and capability of usage control of data in DRM system. |
