Leonardo’s new SignalTrace technology upgrades license plate readers to passively track electronic signals from passenger devices like phones, AirPods, and smartwatches.
ELSAG SignalTrace, developed by Leonardo US Cyber and Security Solutions, is a surveillance tool designed to integrate with existing Automatic License Plate Reader (ALPR) systems. By attaching specialized sensors to ALPR cameras, the system passively collects Bluetooth, Wi-Fi, and RFID identifiers emitted by consumer electronics—including smartwatches, wireless headphones, and smartphones. It then correlates these electronic signatures with the vehicle's license plate and location, establishing an "electronic fingerprint." This allows law enforcement to identify and track individuals even when their license plates are obscured, altered, or missing.
Integrating passive wireless signal sniffing with existing license plate recognition transforms municipal traffic cameras into a dragnet tracking network that violates standard expectations of public anonymity.
- –Passive Bluetooth/Wi-Fi harvesting links individuals to vehicles and physical journeys without a warrant, circumventing standard privacy practices like changing license plates or cars.
- –Personal devices broadcasting identifiers (e.g., AirPods or smartwatches) are turned into tracking beacons, exposing users to continuous, non-consensual surveillance.
- –The commercial packaging of military-grade signals intelligence for domestic law enforcement agencies represents a massive, unchecked escalation in police surveillance capabilities.
