数字版权保护中DCI编码方案及数字证书研究

数字版权标志符为数字内容在互联网上提供唯一的版权身份标志,为确保在网络环境中能够精准定位和检索数字作品、确认版权主体提供了技术基础。建立数字版权标志符体系是我国数字版权管理发展的迫切要求。通过研究DCI（数字版权标志符）的概念、设计原则,分析了国外相关研究的现状,提出了适合我国版权保护的DCI编码方案,并给出了应用于移动互联网的加密机制、数字证书及DCI嵌入方案。研究结果表明,采用上述方法,兼容性好,易于与国际上的DOI（digital object identifier）接轨,加密机制及数字证书的设计适合在移动互联网上应用。

Research of DCI Coding Scheme and Digital Certificates in Digital Copyright Protection

Digital copyright identifier provides a unique identity for digital content on the Internet and the technology foundation,ensures accurate location and retrieval of digital works,confirmming the copyright entity in network environment.The top priority is that DCI（digital copyright identifier） system must be established as soon as possible.On the concept and design principles of DCI,it analyses of relevant foreign research status,proposes coding scheme for copyright protection of our country＇s DCI,and gives encryption mechanisms in the mobile Internet application,digital certifi-cates,and DCI embedded program.Using the above method,it shows good compatibility,easy integration with the Interna-tional DOI（digital object identifier）,encryption and digital certificates are designed for applications on the mobile Internet.
