客户端垃圾邮件过滤系统的设计

摘要

Spam not only consumes large resources of network, but also brings great inconvenience to users. Therefore, research of spare filtering technology is a key problem of the Internet security field. Analyzing the traditional method of filtering, a fingerprint based idea is introduced into email filtering system. A client spam filtering system model is built, by integrating the white and black lists technology, timing filtering, quantitative filtering based on fingerprint and Bayesian filtering technology as well. The system can improve the accuracy of spam filtering and be suitable to user＇s personalized needs.%垃圾邮件不仅浪费大量的网络资源，并且给用户带来很大的不便，如何有效地防范垃圾邮件，已成为网络信息安全领域的主要课题之一。本文通过对传统垃圾邮件过滤技术的分析，提出了一种基于指纹的定量过滤方法。对白名单和黑名单过滤、定时过滤、基于指纹的定量过滤和贝叶斯过滤技术进行了整合，建立了一种客户端垃圾邮件过滤系统的模型，该系统具有较高的过滤准确性，并且能适应用户的个性化需求。
