CEO Hoan Ton-That also revealed Clearview now has 30bn images scraped from platforms such as Facebook, taken without users’ permissions.
The company has been repeatedly fined millions of dollars in Europe and Australia for breaches of privacy.
Critics argue that the police’s use of Clearview puts everyone into a “perpetual police line-up”.
“Whenever they have a photo of a suspect, they will compare it to your face,” says Matthew Guariglia from the Electronic Frontier Foundation says. “It’s far too invasive.”
The figure of a million searches comes from Clearview and has not been confirmed by police. But in a rare admission, Miami Police has confirmed to the BBC it uses this software for every type of crime.
Clearview’s system allows a law enforcement customer to upload a photo of a face and find matches in a database of billions of images it has collected.
