This post is an introduction to Asia Chats a research project analyzing
information controls and privacy in mobile messaging applications used
in Asia. The project will produce a series of reports that will begin
with a focus on WeChat, LINE, and KakaoTalk. Reports will include
analysis based on our technical investigation of censorship or
surveillance functionality, assessment of privacy issues surrounding
these applications’ use and storage of user data, and comparison of the
terms of service and privacy policies of the applications.

This report by Seth Hardy (Senior Security Analyst, Citizen Lab)
describes the technical details of client-side censorship functionality

The China Chats keyword list was tested on Sina Weibo four times from Jun to Aug 2013. The data allows us to identify changes in censorship on Sina Weibo over time.

Working with the just-released China Chats keyword list, Jason Q. Ng extended The Citizen Lab/UNM’s analysis by checking whether each of the 4,256 keywords was blocked from searching on Sina Weibo. This report includes further analysis and examination of other potential censorship tactics by Weibo revealed in the data.
