Hamburg Data Protection Authority is starting preliminary procedures to bring legal action against Facebook over the facial recognition feature used for photo tagging on the social network. The authority decided that further negotiation with Facebook is futile after the social networking giant didn’t agree to obtain consent from users retroactively. Facebook is also having privacy-related legal issues in the U.S. where it is reportedly close to settling accusations of deceptive trade practices brought by the Federal Trade Commission. The company believes that legal action is unnecessary because its tag suggestion feature is compliant with E.U. data protection laws.”]
