一种基于NDIS中间层的图像过滤软件研究

A Software Research for Sensitive Image Filtering Based on NDIS Middle-tier

为使开发者在操作系统内核模式下处理网络数据,Windows网络驱动程序接口规范(NDIS)提供了标准的开发接口。以NDIS中间层驱动程序为基础,能有效实现个人防火墙等应用。而网络不良图像过滤软件的架构是互联网信息监控中的一个关键问题。本文针对以BHO技术实现的图像过滤器插件存在的对非IE内核的浏览器无效等缺陷,设计并实现了一种基于NDIS中间层技术的图像过滤软件。实验表明,该图像过滤软件具有良好的兼容性,并对其它网络信息过滤软件的开发具有一定的借鉴作用。

Windows NDIS defines a standard interface for developers trying to process network data in kernel mode.Some applications,such as personal fire wall etc.,can be realized with NDIS intermediate driver.The architecture for network bad image filtering software is a key in the field of Internet information controlling.To solve the low compatibility of the BHO-based image filter plug-in,the paper designs and implements a development framework for image filtering firewall based on NDIS middle-tier.The experiments show that the image filtering firewall framework has a good universality and compatibility,and the framework can give a reference in developing other network information filtering software.
