基于内容过滤的网络信息审计系统的开发实现

The Development Of Network Info Audit System Based On Content Filtering

内容过滤是当前互联网信息安全的研究热点,也是所面临的挑战之一。本文提出了一种基于内容过滤的网络信息审计系统模型,在信息过滤中相关技术问题如文本过滤和图像过滤的解决方法,并结合linux平台下的开源软件,作出了具体实现。实际应用表明,在不考虑实时性能的前提下,该系统能够有效地对网络信息进行审计和过滤,识别非法信息,提高网络运行的可靠性和安全性。

Content filtering is one of the most hottest research subjects for information security and the challenges too. This article described a framework of network information audit system based on content filtering, it solved the related problems such as text filtering and image filtering. It was realized in the linux OS environment combined with the other open - souce software. The practical application indicated that the system could audit and filter the network information effectively under the condition if not considering the real - time performance, recognized the illegal information and improve network credibility and security.
