一种改进的安全传真服务器设计方法

Improved Design Method of Safety Fax Server

传真服务器存在对垃圾传真防范能力不足的问题。为此,在现有安全传真服务器的设计基础上,提出一种改进方案。在接收传真之前增加图灵检测功能用于筛选自动传真,采用近似串匹配技术对垃圾传真进行确认,进而通过黑名单功能实现垃圾传真的过滤,并将聚类功能作为发现新垃圾传真、丰富关键词库的辅助手段。仿真实验表明,该方法在精度、对垃圾传真反应速度以及智能性等方面均优于原有设计。

Due to the problem of inefficient junk fax prevention,this paper proposes an improved prevention scheme based on the design methods of existing safety fax server.The basic principle is that screen automatic fax by adding Turing test function before receiving faxes.Through approximate string matching technology,junk faxes are detected,and then filtrated by blacklist function.Furthermore,the proposed system regards clustering function as an assistant method to discover new junk fax and rich keyword library.Experimental results show compared with the original design,this method has higher accuracy,faster detection speed,less manual intervention and stronger usability.
