SAN FRANCISCO: Apple has blocked an iPhone facial recognition app built by controversial start-up Clearview AI.
Apple said the app violates the terms of its enterprise-developer program.
The app allows users to use their phone cameras to upload photos or search its database of three billion photos.
Clearview AI was developed by Australian app developer, Hoan Ton-That, who now lives in New York.
It claims to only cater to law enforcement agencies, but investigations have revealed clients also include major private-sector companies.
Its use of images scraped from Internet platforms, such as Facebook, Twitter and YouTube, has raised privacy concerns.
