A secretive startup that promotes a massive international universal facial recognition database seeded from more than three billion images is facing pushback from tech firms as it tries to woo more law enforcement agencies.

The company, called Clearview AI, went from near-complete obscurity to national headlines following a report published by the New York Times in January. The Times described Clearview as a "groundbreaking" facial recognition service. A user imports a photo of a person, and then the app shows "public photos of that person, along with links to where those photos appeared," the NYT explains.
