一种改进的多级信息安全过滤模型

本文在分析了网络主动信息服务模式中存在的安全问题以及常用的安全过滤方法的基础上,提出了一种改进的基于统计和知识特征的多级安全过滤模型,该模型可以进一步提高安全过滤的效率。

Based on the analysis of the security problems in network active information service and several commonly-used security filtering methods, this paper introduces an improved multilevel filtering model based on statistics and knowledge features. This model is expected to further improve the efficiency of security filtering.
