In this report, we study how Tencent, one of China’s largest Internet companies, implements image filtering on WeChat. However, some high profile Internet platforms are known to frequently receive government directives. Previous work has found little consistency in what content different Chinese Internet platforms censor. These requirements form a system of intermediary liability or “ self-discipline” in which Internet platform companies are held liable for content on their services. Internet platform companies operating in China are required by law to control content on their platforms or face penalties, under the expectation that companies will invest in the technology and personnel required to ensure compliance. WeChat’s image censorship is reactive to news events we found censored images covering a wide range of events, including the arrest of Huawei’s CFO, the Sino-US Trade War, and the 2018 US Midterm Elections.WeChat targets predominantly political content including images pertaining to government and social resistance.We compare levels of filtering across WeChat’s Moments, group chat, and 1-to-1 chat features and find that each has different images censored we find that Moments and group chat are generally more heavily filtered than 1-to-1.WeChat facilitates realtime filtering by maintaining a hash index populated by MD5 hashes of images sent by users of the chat platform.

WeChat implements realtime, automatic censorship of chat images based on text contained in images and on an image’s visual similarity to those on a blacklist.
