Madison Square Garden was among the companies named as a client of Clearview AI, a controversial tech company that provides a facial recognition tool that has raised alarms about privacy, in a BuzzFeed News report Thursday. MSG, however, denies that it is a client and says that it used Clearview as a test. The New York Times reports that Clearview is able to match up photos of people with images of them on the internet, allowing users to identify people with a high level of sophistication and speed. “We demoed the product last year and didn’t even move forward with a trial,” an MSG spokesperson said in a statement. Madison Square Garden does use facial recognition at the arena, as part of what it says is a number of security procedures.
