摘　　要：针对数字媒体内容版权保护的需求,提出了一种通用型DRM系统的扩散控制技术,它不依赖于媒体文件格式和媒体的内容。对媒体文件进行加密捆绑封包,只有授权用户才能对其解包以及解密,同时进程监控程序防止用户非法扩散媒体文件内容,进程隐藏方法则对监控程序进行保护,防止用户强制将其关闭。扩散控制技术利用保护文件和被保护媒体的结合与管控,防止了版权内容被非法扩散。In view of the demand of copyright protection of digital media, a technology of diffusion control for general DRM system is proposed. It does not depend on the format and content of media files. Media files are encrypted and packed, which can be only opened by authorized users. Meanwhile, the process monitoring program stops illegal operations of diffusing media file content, and process hiding method prevents the monitoring program from being shut down by users. Diffusion control for general DRM system concerns combining of the protected media files and the protecting files, and it prevents digital media content from being illegally diffused.
