The technology to convert wifi signals into the placement and identity of people is getting much better. Not by using their devices, just the waves bouncing of their bodies. (There's nothing new to the pipeline as far as I can tell, we're just starting to get into the accuracy ranges that make it easy/useful.)

In a study, the researchers describe using beamforming feedback information (BFI) and machine learning models to identify people walking within a network’s range. The team found that this BFI-based technique was able to infer a person’s identity with 99.5% accuracy.

Yipes!

Fortunately, the solution is simple. Your tinfoil hat needs to extend into a cylinder around your entire body, , like an RF condom.

You still be identifiable as the walking cylinder. What we need is a ministry of silly walks.

Wired only network with Faraday caging everywhere. I think they even make signal blocking paint!

You know, I think I just came up with my first $1,000,000 product; drywall with embedded copper mesh.

[–] DudeImMacGyver@kbin.earth 7 points 15 hours ago (1 children)

Sounds pricey.
