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.
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
CCTVflock, 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…
You’d just need metal for this.
I guess lining hats with tinfoil is no longer solely for the paranoid…
