A Designing and Implementary Project on the Courseware DRM System

数字版权保护技术DRM是在网络迅速发展,数字化内容在互联网上发行具有巨大的潜在市场的前提下出现的一种新的对数字信息内容进行保护的技术。它不仅加密保护内容本身,还对内容创作者、所有者的权益进行保护,同时对使用权限进行控制。主要研究在远程教学领域中对多媒体教学课件的版权保护,在对DRM理论进行研究的基础上,提出了课件DRM结构模型和功能流程,对进一步实施系统设计有重要意义。

The article primarily studies the multimedia courseware DRM in the distance education area. it＇firstly introduces the DRM theory, then presents a DRM structure model and functional flow chart, which is very significative for the ulterior development.
