China’s ambition to collect a staggering amount of personal data from everyday citizens is more expansive than previously known, a Times investigation has found. Phone-tracking devices are now everywhere. The police are creating some of the largest DNA databases in the world. And the authorities are building upon facial recognition technology to collect voice prints from the general public.
◦ In a number of the bidding documents, the police said that they wanted to place cameras where people go to fulfill their common needs — like eating, traveling, shopping and entertainment. The police also wanted to install facial recognition cameras inside private spaces, like residential buildings, karaoke lounges and hotels.
◦ Devices known as WiFi sniffers and IMSI catchers can glean information from phones in their vicinity, which allow the police to track a target’s movements. It’s a powerful tool to connect one’s digital footprint, real-life identity and physical whereabouts.
◦ In one case, the bidding documents revealed that the police from a county in Guangdong bought phone trackers with the hope of detecting a Uyghur-to-Chinese dictionary app on phones. This information would indicate that the phone most likely belonged to someone who is a part of the heavily surveilled and oppressed Uyghur ethnic minority.
◦ In the southeast city of Zhongshan, the police wrote in a bidding document that they wanted devices that could record audio from at least a 300-foot radius around cameras. Software would then analyze the voice prints and add them to a database. Police boasted that when combined with facial analysis, they could help pinpoint suspects faster.
◦ The Chinese police are also widely collecting DNA samples from men. Because the Y chromosome is passed down with few mutations, when the police have the y-DNA profile of one man, they also have that of a few generations along the paternal lines in his family…The Times showed that at least 25 out of 31 provinces and regions had built such databases.
◦ The government wants to connect all of these data points to build comprehensive profiles for citizens — which are accessible throughout the government…software [can take] various pieces of data collected about a person and displays their movements, clothing, vehicles, mobile device information and social connections.
