This Anti-Tracking Tool Checks If You’re Being Followed

The Raspberry Pi-powered system, which can be carried around or sit in a car, scans for nearby devices and alerts you if the same phone is detected multiple times within the past 20 minutes. In theory, it can alert you if a car is tailing you.

Edmondson built the system using parts that cost around $200 in total and will present the research project at the Black Hat security conference in Las Vegas this week.
