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.

The reason the FCC is only allowing the sale of state approved routers in the US?

    I’m wondering if some types of crystal can absorb or distort the signals enough to make you harder to identify. I mean I guess you’d be “that guy with the crystals in his pocket” and would be easy to correlate to CCTV flock, but if everyone does it it could create a layer of obscuration.

    Especially things with piezoelectric and/or electromagnetic effects. I’m thinking mainly along the lines of quartz, tourmaline, pyrite, tiger’s eye (hematite/jasper), shungite, etc.

    It would be worth experimenting with if anyone tries that open source software another commenter linked…
