Where everybody knows your face

I’ve seen this facial recognition software in action. It’s both creepy and impressive.

Until recently, Hoan Ton-That’s greatest hits included an obscure iPhone game and an app that let people put Donald Trump’s distinctive yellow hair on their own photos.

Then Mr. Ton-That — an Australian techie and onetime model — did something momentous: He invented a tool that could end your ability to walk down the street anonymously, and provided it to hundreds of law enforcement agencies, ranging from local cops in Florida to the F.B.I. and the Department of Homeland Security.

His tiny company, Clearview AI, devised a groundbreaking facial recognition app. You take a picture of a person, upload it and get to see public photos of that person, along with links to where those photos appeared. The system — whose backbone is a database of more than three billion images that Clearview claims to have scraped from Facebook, YouTube, Venmo and millions of other websites — goes far beyond anything ever constructed by the United States government or Silicon Valley giants.

Being publicly recognizable is not really a concern to someone like me, since I was never given a choice about going public on the Internet or not. But it is a massive problem for the average individual, even those who have been careful to avoid social media. Sooner, rather than later, nations and their lawmakers are going to have to decide whether to embrace or reject the use of identification technology. I assume that most of them are going to embrace it, although the governments that come after the complete collapse of the neo-liberal world order may not.
