Facebook said on Wednesday that it had agreed to pay $550 million to settle a class-action lawsuit over its use of facial recognition technology in Illinois, giving privacy groups a major victory that again raised questions about the social network’s data-mining practices.
The case stemmed from Facebook’s photo-labeling service, Tag Suggestions, which uses face-matching software to suggest the names of people in users’ photos. The suit said the Silicon Valley company violated an Illinois biometric privacy law by harvesting facial data for Tag Suggestions from the photos of millions of users in the state without their permission and without telling them how long the data would be kept.
