Our machines can very easily recognise you among at least 2 billion people in a matter of seconds

Yitu’s Dragonfly Eye generic portrait platform already has 1.8 billion photographs to work with: those logged in the national database and you, if you have visited China recently. Yitu will not say whether Hong Kong identity card holders have been logged in the government’s database, for which the company provides navigation software and algor­ithms, but 320 million of the photos have come from China’s borders, including ports and airports, where pictures are taken of everyone who enters and leaves the country.

According to Yitu, its platform is also in service with more than 20 provincial public security departments, and is used as part of more than 150 municipal public security systems across the country, and Dragonfly Eye has already proved its worth. On its very first day of operation on the Shanghai Metro, in January, the system identified a wanted man when he entered a station. After matching his face against the database, Dragonfly Eye sent his photo to a policeman, who made an arrest. In the following three months, 567 suspected lawbreakers were caught on the city’s underground network.

Imagine this performed by a human eye augmented by AR lenses or glasses.

If you think that humans will confine this sort of applications to a computer at your desk or inside your pocket, you are delusional.
