MARYLAND (WBFF) — A company that supplies license-plate readers to police across central Maryland is now selling a tool that also detects Bluetooth, Wi-Fi and other wireless signals given off by personal devices in passing vehicles, and one local police department is testing it, while another says it plans to use it.
The Prince George’s County Police Department said it is piloting the technology, called SignalTrace, and the Harford County Sheriff’s Office said it plans to use it but remains in the research stage, with no deployment timeline.
An ad on SignalTrace’s website asks: “What if law enforcement could identify suspects by the electronic devices they use?” It then explains that the tech “creates a digital fingerprint for devices that routinely travel together.”
A civil liberties advocate says police shouldn’t be using it at all.
