SignalTrace: New Tech Links Your Devices to Your Car, Expanding Surveillance
Leonardo’s SignalTrace (ELSAG SignalTrace) is a new device that reads electronic signatures from devices like phones, smartwatches, and air tags and links them with license plate data from ALPRs to map individuals’ movements and even convoys. The company claims it only flags signatures during investigations and does not decrypt content, but privacy advocates warn that opting out isn’t possible and the expanded data linkage raises legitimate concerns about misuse and chilling effects in policing.
