I know people, funded, building WiFi scanners, but for the industry. They are cheap and can scan big stuff but they are quite imprecise, I wonder if you have like to stand in a specific pose on a specific spot for it to work?

Humans can be tracked with unique 'fingerprint' based on how their bodies block Wi-Fi signals
(www.theregister.com)
Cool
If it doesn’t get used for bad purposes it is very cool yes. So no it’s not cool at all. It’s fucked.
People willingly provide enough tracking of themselves already
While this could have military applications, the need to generate a profile of the person you want to track makes this less of a concern for your average “carries a phone everywhere” person
Tech companies are always foaming at the mouth to get more data. Yes they know who you are but what do you think, how do you feel, how do you move? The only way to go is to get richer data. This satisfies that addiction. You really think mark Zuckerberg won’t use this against you if he can?
Time to carry a WiFi jammer
The resulting image must just basically look like a shadow, I can't imagine that they're going to get much internal detail with Wi-Fi considering that my router's signal practically gets blocked by a piece of cardboard.
This research essentially amounts to, humans can be individually identified with nothing more than low quality x-rays. Well yeah, so what, you can also use visible light and in any situation where you're going to use Wi-Fi to detect someone, it's got to be easier to buy a cheap CCTV camera.
