对等网环境下基于中间件的DRM模型

在由相异的通信终端组成的对等网中实现交互式数字版权管理功能是一项具有挑战性的难题,因为整个对等网框架不受任何限制规则的约束,这就给网络监控带来了麻烦。在这种情况下,既要保护内容服务提供商的原始投资和经济利益,又要预防未经授权而实施拷贝与转发等非法行为,同时还要维护各终端用户个人隐私,为此,创建性地提出了在对等网拓扑结构中使用中间件技术来保证版权管理的正确执行,从而能在静态与便携式终端设备间交换数据文档;此外,所提出的中间件技术还能保证在分布式计算环境中为版权管理系统提供安全可信的计算平台。

Middleware -based DRM Model in P2P Frameworks

Performing DRM in collaborative,P2P networks consisting dissimilar kinds of communication terminals is a challenge,since it is arduous to watch the network running in a P2P framework that's not supervised by any regulations.In such situation,efficient revenue generation for the content service providers for distributed content,prevention of unauthorized reprography and redistribution,and sustaining anonymity of the peers are some of the foremost challenges.A middleware for DRM enforcement in P2P network topology including static and portable equipments that exchange document among themselves is brought forward.The suggested middleware provides a trusted computing platform for DRM enforcement in distributed computing environments.
