摘要
随着信息化技术的发展和互联网的普及,各高校都在建设数字多媒体教育资源库,然而数字多媒体资源非常容易受到复制粘贴技术的侵害。为了保护留学生数字媒体教育资源版权,在分析既有数字媒体教育资源版权保护现状的基础上,采用基于XML数字权限认证的方法,提出了一种数字媒体教育资源保护框架。该框架基于授权文件和身份验证,同时结合水印技术,具有本地播放和回放的功能。模型的应用结果表明,能够有效解决数字媒体教育资源版权保护的问题,具有一定的示范和借鉴意义。
With the development of information technology and popularity of Internet,all colleges and universities are constructing their digital databases of multimedia educational resources.

In order o protect the copyright of the digital media education resources for international students, based on the status analysis of the digital media education resources copyright protection and XML digital authority authentication method,a framework of digital media education resource protection is put forward. The framework has the function of local player and playback because it is based on the authorization file and identity verification,and the watermark technology is applied in it. The model application results indicate it can effectively solve the problem of copyright protection of digital media education resources,and has a certain significance for demonstration and reference.
