A New York Times report that Ukrainian protesters received text messages informing them they had been "registered as a participant in a mass disturbance" means the Ukrainian government is tracking protesters' locations through their cellphones.

"This incident highlights how location metadata ... can easily be used by governments to identify and suppress protesters attempting to exercise their right to free expression," said Kevin Bankston of the New America Foundation's Open Technology Institute.
