A Northern California judge has ruled that federal authorities can’t force you to unlock your smartphone using your fingerprints or other biometric features such as facial recognition. The ruling came in the case of two unspecified suspects allegedly using Facebook Messenger to threaten a man with the release of an “embarrassing video” to the public if he did not hand over money. The federal authorities requested a search warrant for an Oakland residence, seeking to seize multiple devices connected to the suspects and then compel anybody on the premises to unlock the devices using fingerprint, facial or iris recognition.
