Scientists in Germany have demonstrated a startling new form of surveillance: identifying people using nothing more than ordinary WiFi signals. By analyzing how radio waves bounce around a room, researchers can effectively “see” and recognize individuals — even if they are not carrying a device and even if their phone is turned off.
Would carrying around some sort of Wifi disruptor help against this? It would likely have to be a passive persistent effect, not something like an EMP (but those we can reserve for particularly annoying snoopers).
I mentioned this in a another reply, but you just need a microwave oven basically :)
Super now I just need to find one of these in portable form factor. And a good battery.
Particularly annoying snoopers sounds like some people in my nieghborhood
