摘要: 鉴于当前权利描述语言不能有效地实现数字内容的分段权利描述和动态分段授权,提出一种基于分段控制模型。在描述了分段数字内容加密封装后,对ODRL模型进行扩展,实现了数字内容的分段权利描述和动态分段授权,利用扩展后的ODRL模型深入探讨和分析了分段控制下的DRM二次分发。通过相关分析表明,扩展后的模型安全可靠,易于实现。

Abstract: Currently, Digital Rights Management(DRM) can not effectively implement segment rights expression and dynamic segment authority, this paper demonstrates a model based sectional control. After describing the encryption and packaging of sectional digital content, this model carries out segment rights expression and dynamic segment authority through the extended ODRL model. Finally this paper deeply explores and analyzes the process of DRM secondary distribution based sectional control with the extended ODRL model. The correlation analysis shows that the extended ODRL model is secure, and easy implementation.
