Meta will use facial recognition technology to help people check whether they are being used in scams.
The new technology is an attempt to beat “celebrity bait” adverts that falsely use people’s likeness to push scam ads and other misleading and malicious content.
The tool will compare people’s pictures with those on their Facebook and Instagram, and use those to give the real owners control of their accounts.
The feature is being tested globally, it said. But for now it will not come to the UK or EU, and Meta said that it was talking to regulators about how to do so.
Under the new system, when Meta’s existing technologies spot a post it believes to be a scam and it contains an image of a public figure “at risk for celeb-bait”, it will use facial recognition to compare faces in the ad against the public figure’s own Facebook and Instagram profile pictures.
“If we confirm a match and that the ad is a scam, we’ll block it,” the company said.
“We immediately delete any facial data generated from ads for this one-time comparison regardless of whether our system finds a match, and we don’t use it for any other purpose.”
Meta said early testing of this scheme with a “small group of celebrities and public figures” had shown “promising results” when it came to “increasing the speed and efficacy” of spotting and removing scam ads of this kind.
It added that over the coming weeks, it would start alerting a larger group of figures who have been used in scam ads to let them know that they would be enrolled into the new scheme – and would allow them to opt out if they so wished.
Elsewhere, Meta said it was also now testing using facial recognition and video selfies as a means for people to verify their identity and regain access to an account that had been compromised.
The video would then be compared to the profile picture on the account the user was trying to access.
Monika Bickert, Meta’s vice president of content policy, said: “Scammers are relentless and continuously evolve their tactics to try to evade detection.
“We’re just as determined to stay ahead of them and will keep building and testing new technical defences to strengthen our detection and enforcement capabilities.
“We have vetted these measures through our robust privacy and risk review process and built important safeguards, like sending notifications to educate people on how they work, giving people controls and ensuring we delete people’s facial data as soon as it’s no longer needed.
“We want to help protect people and their accounts and while the adversarial nature of this space means we won’t always get it right, we believe that facial recognition technology can help us be faster, more accurate and more effective.
“We’ll continue to discuss our ongoing investments in this area with regulators, policymakers and other experts.”
