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.
Yes, however do you remember the big fuss over 5g tower tech coming from Huawei and how that is a security issue? Well turns out the 5g towers can employ beam forming for better connection with each phone. And the interesting thing is that AESA radars work much the same - so you can imagine what a nation wide network of these towers would provide for china in terms of air traffic information
Sure, but why bother?
Practically speaking, we all carry trackers in our pockets, attached to our phone number, email and social media. We already consent to giving away all that data, which basic ping triangulation also allows for fairly granular location tracking.
The wifi tracking method is helpful because it very granular in an otherwise opaque area. It tracks based on body size, who does what around the house, who specifically watched what on TV.
very few people did consent to that.
or are you saying that if I unknowingly drink poisoned water, I did consent to that?
You clicked “accept” once on one thing ever, which they consider legal permission to sell all data to anyone buying.
In that last comment, they said air traffic information. So think military aircraft movements.
