Millions of Facebook users in Illinois are being notified that they could be involved in a lawsuit, over the social media giant’s use of facial tagging. A court-appointed administrator on Monday began sending emails to users who live in Illinois for at least 60 consecutive days between June 7th, 2011 and mid-April of this year, explaining that they could be apart of the class-action lawsuit against the social network. That was according to the associate general counsel at Facebook Nikki Sokol. Facebook is also sending users who meet those criteria a notification through their accounts and letting them know that they can be involved in the lawsuit, with an additional item appearing in their news feed. Those notifications must be sent in by this Thursday, if you want to be involved. The lawsuit was filed in federal court in Chicago back in 2015 and later got moved to federal court in San Francisco, which alleged that Facebook violated Illinois’ Biometric Information Privacy Act. They did this by failing to obtain written consent from users before creating templates of their faces from photos and by not property notifying them about how the information would be used or how long it would be kept. The suit asks the court to award damages of $5,000 for each reckless violation of the Illinois law and $1,000 for each negligent violation. The judge who is hearing the case granted the class-action lawsuit for a status hearing in April, and said that his order of damages could be increased to some amount in the billions. Facebook denies the allegations and is currently fighting in court, after they started rolling out its facial tagging feature for photos back in 2010. The social media platform has information on its website, in regard to this feature and points that users can go to their settings and disable the feature. Back in December, it introduces a new tool that helps users better manage the use of facial recognition. The trial for the Facebook case is expected to begin in July.
