China uses big data to select Uighur Muslims for detention: HRW
China is using a big data programme for policing in the Xinjiang region that arbitrarily selects Uighur Muslims for possible detention, a Human Rights Watch (HRW) report said. The data is compiled from activities on personal phones, including call logs and the duration of the calls. China's brutal repression of its Muslim minority is being turbocharged by technology, HRW added.
