【摘要】：在互联网发展迅速的当今时代，由于数字媒体便于复制、分发等特性，受知识产权保护的数字产品和内容被批量复制和随意传播的现象普遍存在，数字版权管理应运而生，并且受到了全球许多组织和厂商的热切关注。DRM系统在有效保护数字内容的同时，又从不同的途径侵犯了用户的隐私权。而当今用户的数据信息和隐私都密切关系着众多的经济利益，因此在保证数字内容有效管理的同时保护用户的隐私是十分必要的。在所有的DRM技术标准中，目前最成熟，参与者最多，影响力最大的标准要属开放移动联盟（OMA）制定的OMA DRM标准了，虽然OMA DRM标准定义了DRM系统的体系架构以及内容中心，版权中心等功能实体，但是在用户隐私保护方面还需要进一步的完善。本文针对DRM系统中用户隐私保护的问题展开研究，首先对DRM相关技术和OMA DRM进行简要介绍，然后对移动数字版权管理和OMA DRM中用户隐私保护技术进行了研究，针对OMA DRM中用户隐私保护提出了一种移动数字版权管理系统中的用户隐私保护方法，使得在满足DRM系统中对数字版权管理的要求的同时，保护了用户所购买的数字内容隐私。在本文提出方法中，按照OMA DRM标准定义，设计并实现一个DRM数字版权管理系统，配合通用的内容提供服务器，许可证服务器，，DRM客户端，结合不经意传输协议方法来对版权对象获取协议（ROAP）过程进行改进来实现DRM用户隐私保护。并且详细的给出了基于不经意传输改进ROAP协议与DRM数字证书注册、获取、更新和撤销过程中实现具体环境下的DRM用户隐私保护设计。本文还针对所提出的DRM用户隐私保护方法进行实验，并从安全，性能等方面做比较，进一步验证了系统可行性和实用性。本文最后对全文做出了总结并提出了今后工作研究和方向。
[Abstract]:In the era of rapid development of the Internet, the phenomenon that digital products and content protected by intellectual property rights are copied in batches and spread at will is widespread because digital media is convenient for reproduction and distribution, so digital rights management emerges as the times require. And it has attracted intense attention from many organizations and manufacturers around the world, while effectively protecting digital content. The data information and privacy of users are closely related to many economic interests, so it is necessary to ensure the effective management of digital content at the same time to protect the privacy of users. Of all the DRM technical standards, the most mature, most participant, and most influential standard is the OMA DRM standard developed by the Open Mobile Alliance (OMA), although the OMA DRM standard defines the architecture and content center of the DRM system. Copyright center and other functional entities, but in terms of user privacy protection needs to be further improved. In this paper, the problems of user privacy protection in DRM system are studied. Firstly, the related technologies of DRM and OMA DRM are briefly introduced, and then the technologies of mobile digital rights management and user privacy protection in OMA DRM are studied. This paper presents a method of user privacy protection in mobile digital rights management system in OMA DRM, which can meet the requirements of digital rights management in DRM system at the same time. In this paper, according to the definition of OMA DRM standard, a DRM digital rights management system is designed and implemented. Combining the method of casual transfer protocol to improve the process of copyright object acquisition protocol (ROAPP) to realize the privacy protection of DRM users, the improved ROAP protocol and DRM digital certificate registration based on inadvertent transmission are presented in detail. In the process of updating and revocation, the design of DRM user privacy protection under specific environment is implemented. This paper also carries out experiments on the proposed DRM user privacy protection method, and makes a comparison in terms of security, performance, etc. The feasibility and practicability of the system are further verified. Finally, the paper summarizes the full text and puts forward the future research and direction.
