张学友成逃犯克星”,中国技术再次震惊了外媒
Chinese police are increasingly relying on artificial intelligence as they take the motto "you can run, but you can't hide" to a whole new level. In less than two months, police in three cities across the country caught three different suspected criminals at concerts of popular Hong Kong singer Jacky Cheung. Facial recognition technology identified the men as they passed through security checkpoints, according to state media. Although the three suspects were all wanted for relatively minor crimes, the string of concert arrests has generated headlines throughout China, prompting the star to address the issue. "I thank them for attending my concerts," Cheung told reporters. "But it did give everyone food for thought: If you steal, you'll get caught no matter where you go." Police in Luoyang, a central Chinese city where Cheung plans to hold a concert in July, have tweeted: "Jacky, we are ready!" State media has highlighted a growing number of areas -- including in some unlikely places -- where sophisticated facial recognition is being deployed. Traffic police in Shenzhen in late April installed dozens of high-tech devices in the southern Chinese metropolis, targeting jaywalkers and scooter-riding couriers who are known to flout traffic rules. "Wearing helmets or hats? You will still be recognized for sure!" the police warned in a social media post. "Our facial recognition devices are not affected by weather or skin tones -- and our algorithms can detect people even when they turn sideways, lower their heads, partially cover their faces, or in high-brightness, backlit or crowded conditions." Just a week after the system's soft launch, Shenzhen traffic police said they had caught violators in almost 900 cases and planned to expand its use. High-tech surveillance isn't limited to law enforcement in China, either. Last year, the Temple of Heaven park in Beijing found itself in the spotlight when it installed facial recognition in public bathroom to stop people from stealing toilet paper. A high school in Hangzhou in eastern China last week unveiled a system that would allow the recording and real-time analysis of students' facial expressions in classrooms, according to state media. If the system categorizes a student as "non-attentive," an alert will be sent to the teacher. |
