One of the surveillance industry’s recent — and much publicised — success stories took place at a pop concert in eastern China. While Jacky Cheung, a Hong Kong pop star (rebranded a “fugitive trapper” by the Chinese media) crooned, cameras were automatically sweeping the audience. Facial-recognition technology picked out four men accused of crimes — including a ticket scalper and a greengrocer accused of a Rmb110,000 potato scam in 2015. “Smiling as he approached his idol, he did not realise he had already been spotted,” Jiaxing police gloated in a social-media post.
Some of China’s leading facial-recognition players, for example, are now moving into gait recognition. Hanwang Technology was an early entrant in the field: it was forced to rethink its fingerprint-recognition technology when the Sars epidemic of 2005 left people in China terrified of physical contact. “We can see the human figure and his gait, so if his cap is pulled down [we] can still recognise him,” explains Liu Changping, president of the Beijing-based company. The Chinese authorities already have a decent video database to build on, he adds: “If [someone] was put in prison before, there’s video of him walking around.”
That is from Louis Lucas and Emily Feng from the FT, interesting throughout.
