Facebook must face a class action lawsuit over its use of facial recognition technology, a California judge has ruled.
The lawsuit alleges that Facebook gathered biometric information without users' explicit consent.
It involves the "tag suggestions" technology, which spots users' friends in uploaded photos; the lawsuit says this breaches Illinois state law.
Facebook said the case had no merit and it would fight it vigorously.
