How would a person be able to avoid this?

That's one scary implication: they can't.

Unless, of course, they are aware of it and try to subvert it by consciously modifying "their body shape characteristics and motion patterns".

The only good application of this work I can come up with is to reduce the danger that comes from surprised cops in no-knock warrants. Still kinda evil though.

Useful for detecting if aged or ailing family members haven't moved in a while, and check on them.

A team from MIT has created a product for this specific purpose using a very similar technology: http://www.emeraldforhome.com/

No seriously. Maybe wear some kinda suit?

Run Ethernet throughout your home and hardwire 100% of everything. Disable all wireless radios in your house. That will stop your own gear from being used like this, but unless you turn your home into a faraday cage someone could probably blast your home with 2.4GHz externally to achieve similar results. If as you mention, perhaps you had some kind of suit that is completely absorbent to wireless spectrum, though that in itself could be used as an identifier most likely.

This is a type of passive identification I hadn't imagined before. It's pretty impressive to see 90% identification for a set of 6 users.

I can't imagine it's accurate enough to use for secure verification. I could see it's application for a shared entertainment system (ps4, netflix, etc) where identification is primarily for configuration purposes, not security.

Turn the wifi hotspot on on your phone and blind it. It probably won't work so well if the background wifi signals keep moving around.

What I meant was that the suit would change your "wifi fingerprint", not that it would be absorbent.
