San Francisco: A US court here has ruled that Facebook users from Illinois state can go ahead with a class action lawsuit against social media giant Facebook over alleged illegal collection of user data without their consent. US non-profit group, the American Civil Liberties Union (ACLU), quoted a court document as saying that the Ninth US Circuit Court of Appeals in San Francisco gave a green light to the Illinois users to sue FB over privacy breach by using the technology of facial recognition, Xinhua news agency reported on Thursday. Judge Sandra Ikuta said in the ruling that Illinois users can bring a class action lawsuit against FB, whose facial recognition software “invades an individual’s private affairs and concrete interests”. The Circuit Court rejected a FB appeal to block the class action lawsuit by the FB users who accused the US media company of storing biometric data for millions of users without their consent. (IANS)
