PROVIDENCE, R.I. — 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.

Facebook’s about-face follows a busy few weeks. On Thursday it announced its new name Meta for Facebook the company, but not the social network. The change, it said, will help it focus on building technology for what it envisions as the next iteration of the internet — the “metaverse.”

The company is also facing perhaps its biggest public relations crisis to date after leaked documents from whistleblower Frances Haugen showed that it has known about the harms its products cause and often did little or nothing to mitigate them.

Facebook didn’t immediately respond to questions about how people could verify that their image data was deleted, or what it would be doing with the underlying technology.

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.

Facebook in 2019 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.

Meta Platforms Inc., Facebook’s parent company, appears to be looking at new forms of identifying people. Pesenti said Tuesday’s announcement involves a “company-wide move away from this kind of broad identification, and toward narrower forms of personal authentication.”

“Facial recognition can be particularly valuable when the technology operates privately on a person’s own devices,” he wrote. “This method of on-device facial recognition, requiring no communication of face data with an external server, is most commonly deployed today in the systems used to unlock smartphones.”

Apple uses this kind of technology to power its Face ID system for unlocking iPhones.

Researchers and privacy activists have spent years raising questions about the tech industry’s use of face-scanning software, citing studies that found it worked unevenly across boundaries of race, gender or age. One concern has been that the technology can incorrectly identify people with darker skin.

Facebook found itself on the other end of the debate last year when it demanded that facial recognition startup ClearviewAI, which works with police, stop harvesting Facebook and Instagram user images to identify the people in them.

Concerns also have grown because of increasing awareness of the Chinese government’s extensive video surveillance system, especially as it’s been employed in a region home to one of China’s largely Muslim ethnic minority populations.

Facebook’s huge repository of images shared by users helped make it a powerhouse for improvements in computer vision, a branch of artificial intelligence.
