China's government is using facial-recognition technology to help promote good behavior and catch lawbreakers, reports the WSJ. From the article: Facial-recognition technology, once a specter of dystopian science fiction, is becoming a feature of daily life in China, where authorities are using it on streets, in subway stations, at airports and at border crossings in a vast experiment in social engineering (alternative source). Their goal: to influence behavior and identify lawbreakers. Ms. Gan, 31 years old, had been caught on camera crossing illegally here once before, allowing the system to match her two images. Text displayed on the crosswalk screens identified her as a repeat offender. "I won't ever run a red light again," she said. China is rushing to deploy new technologies to monitor its people in ways that would spook many in the U.S. and the West. Unfettered by privacy concerns or public debate, Beijing's authoritarian leaders are installing iris scanners at security checkpoints in troubled regions and using sophisticated software to monitor ramblings on social media. By 2020, the government hopes to implement a national "social credit" system that would assign every citizen a rating based on how they behave at work, in public venues and in their financial dealings.
