China's Algorithms of Repression Reverse Engineering a Xinjiang Police Mass Surveillance App

"This report presents new evidence about the surveillance state in Xinjiang, where the government has subjected 13 million Turkic Muslims to heightened repression as part of its 'Strike Hard Campaign against Violent Terrorism.' 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."--Publisher website.
