一种新的垃圾邮件过滤技术的研究与实现

ON A NEW E-MAIL SPAM FILTERING TECHNOLOGY AND ITS IMPLEMENTATION

通过对垃圾邮件的现状、特征、以及现有的垃圾邮件过滤技术的分析研究,提出一种基于过滤规则和IP信誉的垃圾邮件过滤技术。方法改进了传统的黑白名单技术,加入了评分机制,对IP进行评分,把IP信誉细分为四个等级,分别为优、良、中、差,并结合基于过滤规则的垃圾邮件过滤技术,互补不足,以达到更好的垃圾邮件过滤效果。同时,设计加入了用户反馈,以弥补因误判而造成的损失。实验表明,设计适于用户终端使用,有较高的可行性。

Based on analytical study on the actualities and characteristics of junk mail and on existing e-mail spam filtering technologies, a new spam filtering technology based on filtering rules and IP reputation is proposed. To improve traditional DNS blacklists technology, this method adds marking mechanism into it to mark the IP. IP reputation is subdivided into four grades, namely excellent, good, medium and bad. To complement the shortcomings each other and achieve better filtering results, the marking method is combined with the junk mail filtering technology based on filtering rules. Meanwhile, the user feedback is introduced to the design to make up the losses caused from misjudgement. Experimental results show that the design is quite suitable for user terminals and has high feasibility.
