摘　　要：现有过滤系统中绝大多数方案都采用了传统的过滤技术,这些过滤技术无法制止不良多媒体信息在网络上传播。基于此,提出了一种基于内容的分布式多媒体流过滤系统的模型,该系统采用内容识别与包过滤相结合的方式,让内容识别过程与包过滤规则匹配并行进行,实现过滤系统的实时性;同时该系统设计的补偿Agent在屏蔽非法信息的同时,保证了多媒体文件的完整性。The traditional filtration technologies are is widely used in the vast majority of progames in the existing filtration system. Whereas the traditional technologies can not stop the spread of non - performing multimedia information in the internet. This paper proposes a model of a distributed content - based filtering system of multimedia stream. The system realizes the realtime of filtering system where the content identifieaiton process and packet filtration can be done at the same time. The Agent compensation in the sytem shields the illegal information and ensures the integrity of multimedia files.
