本报告延续上一篇针对微信朋友圈图片过滤技术的研究，分析微信如何在聊天功能中实现实时图片过滤。微信是中国腾讯控股有限公司旗下的即时通讯应用，目前是中国最受欢迎的聊天软件之一，也是全球排名第四的最流行聊天软件。朋友圈是微信上最常用的功能之一，其中图片是用户最期望看到的内容分享形式。

In this work, we study how Tencent implements image filtering on WeChat. We found that Tencent implements realtime, automatic censorship of chat images on WeChat based on what text is in an image and based on an image’s visual similarity to those on a blacklist. Tencent facilitates this realtime filtering by maintaining a hash index of MD5 hashes of sensitive image files.
