Signal Trace software use a faraday bag need to know
The short version: A creator breaks down signal-tracing tools and Faraday bags, a reminder that personal device hygiene is one piece of the broader anti-surveillance puzzle.
Our Take
This video, from the channel Digital ID, Mass Surveillance and Digital Currency, walks through signal-tracing software and Faraday bags as ways to understand and limit what your devices are broadcasting. It's a useful entry point for anyone just starting to think about digital exposure, even if the channel's broader catalog ranges well beyond our core beat of license plate readers.
We'd just add the obvious caveat: a Faraday bag protects your phone, not your car. Flock Safety cameras and other ALPR systems don't need your device to ping—they photograph your plate, log your location, and timestamp it in a database regardless of whether your phone is wrapped in foil. Personal opsec and infrastructure-level surveillance are two different fights, and treating them as one can give people false confidence. Blocking your phone's signal does nothing about the camera on the pole reading your plate as you drive past city hall.
If you want to know what's actually watching you on the road, check our camera map to see documented ALPR locations near you, and visit our take-action page for ways to push back on this infrastructure at the local level, where these fights are actually winnable.
