China's Mass Surveillance Phone App

Chinese authorities are using a mobile app to carry out illegal mass surveillance and arbitrary detention of Muslims in China’s western Xinjiang region.

Between January 2018 and February 2019, Human Rights Watch was able to reverse engineer the mobile app that officials use to connect to the Integrated Joint Operations Platform (IJOP), the Xinjiang policing program that aggregates data about people and flags those deemed potentially threatening. By examining the design of the app, which at the time was publicly available, Human Rights Watch found that Xinjiang authorities are collecting a wide array of information from ordinary people.
