New surveillance tech links your phone to your license plate
Phone and Bluetooth signals could turn roadside cameras into far richer tracking tools.
TL;DR
- SignalTrace system links electronic device signals (like from phones and smartwatches) to vehicle license plate data.
- It recognizes groups of devices that regularly travel together and associates them with license plate records and locations.
- The system can identify a vehicle without seeing its license plate by recognizing the 'electronic signature' of devices associated with it.
- Investigators can use these recurring signal patterns to develop leads and identify individuals, even if their names are not initially known.
- The effectiveness of such systems in identifying individuals is supported by research showing that patterns of movement and proximity can uniquely identify people.
- Legal precedents like Carpenter v. United States and Chatrie v. United States highlight privacy expectations in location data and movements.
- SignalTrace raises questions about how the law should treat systems that identify people indirectly through device patterns and associations.
