A federal judge on Monday ruled that a lawsuit filed over Facebook's use of facial recognition technology can proceed as a class action, raising the possibility the social network could face billions in damages.

The sueball was filed in May 2015 under Illinois' 2008 Biometric Information Privacy Act (BIPA) by three residents of state, Nimesh Patel, Adam Pezen and Carlo Licata, who were upset by the social network's collection of biometric data without adequate notice or consent.
