Security cameras and facial recognition technology are on the rise in China. In 2018, People's Daily, the media mouthpiece of China's ruling Communist Party, claimed on English-language Twitter that the country's facial recognition system was capable of scanning the faces of China's 1.4 billion citizens in just one second. German journalist Kai Strittmatter speaks fluent Mandarin and has studied China for more than 30 years. He says it's not clear whether or not the Chinese government is capable of using facial recognition software in the way it claims. But he adds, on a certain level, the veracity of the claim isn't important.
