Surveillance company Leonardo plans to expand automatic license plate readers so they also collect Bluetooth identifiers from phones, wearables, and other devices in passing vehicles. The feature, called SignalTrace, would let cameras designed to track cars also help identify and follow specific drivers or passengers by correlating vehicle sightings with nearby device signals. The article describes a product and deployment capability rather than a disclosed software flaw or CVE.
Why it matters: This would make a widely used police tracking tool more invasive by linking vehicles to people, not just plates. It matters for public oversight, privacy advocates, and communities affected by law-enforcement surveillance, because it could significantly widen location tracking without users doing anything wrong.
