Abstract

Abstract: A new firewall of image content filtering is attempted to be present in this article，it analyzes content based on web page logo，and synthetically using many kinds of arithmetic to compare with similarity of every logo，then decides to filter the web page or not.Because this type of image is small，and filter speed is fast，this method can be used to improve defect which is about image content filtering in present firewall，enhance the ability of filtering and the speed of filtering in the firewall.

Key words: Web page logo, firewall, histogram, similarity

摘要： 提出一种新的图像内容过滤防火墙，针对网页标识（Logo）进行图像内容分析，综合应用多种算法比较各个标识之间的相似度，由此来判定是否过滤网页。由于这类图像体积小，处理速度快，将其应用在防火墙中很好地改善了当前防火墙在图像内容过滤方面的不足，提高防火墙的过滤能力和过滤速度。

关键词: 网页标识, 防火墙, 直方图, 相似度
