摘要
对等网络因其具有分布式、自组织、带宽利用率高等特点,在分布式文件分发、多媒体传输、网络流媒体服务方面有着广阔的应用前景,成为研究领域的一个热点。但是由于对等网络分布式的结构特点,必须引入版权保护机制对多媒体文件版权进行保护。文章提出了一种P2P环境下支持版权交易的DRM模型,为解决对等网络下的版权交易问题提出了一个可行的方案。
P2P network for its characteristics of distributed, self-organization, higher bandwidth utilization, has a broad application prospects in file distribution, multimedia transmission, Internet streaming media business and so on, and has become a hot spot of research field. However, because of the structural characteristics of the distributed, it is necessary to introduce copyright protection of multimedia files, with people's increasing demand in copyright trading; we propose a digital right management model (DRM) to resell the ownership of copyright for P2P networks, as a feasible solution to the problem proposed above.
