Facebook said it will shut down its face-recognition system and delete the faceprints of more than 1 billion people amid growing concerns about the technology and its misuse by governments, police and others.

"This change will represent one of the largest shifts in facial recognition usage in the technology's history," Jerome Pesenti, vice president of artificial intelligence for Facebook's new parent company, Meta, wrote in a blog post on Tuesday.
He said the company was trying to weigh the positive use cases for the technology "against growing societal concerns, especially as regulators have yet to provide clear rules." The company in the coming weeks will delete "more than a billion people's individual facial recognition templates," he said.
More than a third of Facebook's daily active users have opted in to have their faces recognized by the social network's system. That's about 640 million people. Facebook introduced facial recognition more than a decade ago but gradually made it easier to opt out of the feature as it faced scrutiny from courts and regulators.
In 2019 Facebook stopped automatically recognizing people in photos and suggesting people "tag" them, and instead of making that the default, asked users to choose if they wanted to use its facial recognition feature.
Facebook's decision to shut down its system "is a good example of trying to make product decisions that are good for the user and the company," said Kristen Martin, a professor of technology ethics at the University of Notre Dame. She added that the move also demonstrates the power of public and regulatory pressure, since the face recognition system has been the subject of harsh criticism for over a decade.
Company spokesperson Jason Grosse said that user templates will be "marked for deletion" if their face-recognition settings are on, and that the deletion process should be completed and verified in "coming weeks." On the second, point, Grosse said that Facebook will be "turning off" components of the system associated with the face-recognition settings.
Meta's newly wary approach to facial recognition follows decisions by other U.S. tech giants such as Amazon, Microsoft and IBM last year to end or pause their sales of facial recognition software to police, citing concerns about false identifications and amid a broader U..reckoning over policing and racial injustice.
