A smart surveillance system that can identify criminals among a database of 2 billion faces within seconds has been revealed in China.
The system connects to millions of CCTV cameras and uses artificial intelligence to pick out targets.
Known as ‘Dragonfly Eye’, it has already been used in Shanghai to track down hundreds of wanted criminals, reports suggest.
The company behind the technology, Shanghai-based Yitu Technology, said Dragonfly Eye scans images from the country’s national database.
The photos include images of visitors to the city and those taken at its many ports and airports.
‘Our machines can very easily recognise you among at least 2 billion people in a matter of seconds,’ Yitu chief executive and co-founder, Zhu Long, told the South China Morning Post.
