多媒体数字信息全程跟踪及信息安全保护系统研究

All-lifetime Tracing and Protecting the Multi-media Digital Information over Internet

分析了当前有关信息安全保护措施及其缺陷，提出了一种新的信息安全保护技术—多媒体数字信息全程跟踪及信息安全保护系统。它能将信息侵权行为的约束贯穿于信息产品的整个生命期(从生产者发布信息开始直至信息消亡)，而且信息超级用户能对带产权的信息产品进行全程跟踪。

In this paper, the strategies of protecting the information and their limitations are analyzed. A new method－all-lifetime tracing and protecting the multi-media digital information over internet is proposed. This method can protect the copyrights of the multi-media digital information at any time. The super-users can trace the distribution and the usage of the multi-media digital information.
