There are no legitimate uses of this technique. It only applies if you lack the consent of the target. If have that, there are many easier and better ways to monitor them.

A personal home security system could make better use of this instead of motion sensors in each room.

Earlier quoted context omitted.

Maybe SWAT can use this to validate that it's actually the right house when serving a no-knock warrant. I'm cynical enough to feel like there's no way this is good for any of their targets, though. Edit: Kolpa makes a really good point! This seems like a really good counter to SWATting, where the claim is that someone is holding hostages or something -- this could pretty effectively demonstrate that to be false if th…

> Maybe SWAT can use this to validate that it's actually the right house when serving a no-knock warrant. How would a stick figure images help a SWAT team validate that they're at the right house? This could only help them by giving them a clue about where to point their guns once they bust down the door.

For example, if they are expecting to find someone with several hostages, and they only find people lying in bed...

Look at the list of names on this paper. We better fix our immigration system for high skill individuals.

Devil's advocate: "let's fund PhDs with respectable salaries instead of green cards."

How does that solve the problem of attracting talent?

I've noticed, recently, that literally every major chain store I go into blocks my cell signal. I get full bars outside, perfect LTE, and about 5 ft past the glass doors, I'm suddenly cut off. Specifically, Meijer grocery stores and Home Depot are the worst offenders. Coincidentally they offer free in store WiFi to track me with, so I turn off my wifi radio on both smartphone and smartwatch before walking in the door…

FWIW, if they are intentionally (or unintentionally) blocking your cell signal with an electronic signal (And since you mentioned that they didn't remodel, this is the only way they could feasibly do it), they're breaking a very serious FCC law - https://www.fcc.gov/general/jammer-enforcement . I know that the FCC is kind of regarded as a joke lately, but this is a law they take pretty seriously as jammers can interf…

Yeah, I think it's more what lgats suggested, and simply that they have a naturally impermeable building in the middle. Not even the cabinets, more the metal shelving up to the ceiling and such. I also notice that my current phone does a terrible job of falling back on the much more long distance 3G, so maybe that's part of it.

I believe you can achieve the same result in your home by adding a sheet metal roof, metal cabinets, and refrigerators along every wall.

That's probably it. Perhaps I want some decorative brushed aluminum sheet metal instead of drywall...

Having discussed this with a couple of friends off of here, I should add some evidence of the tracking[0]. I agree with lgats sibling comment that this is likely just a function of the construction of the building and not outright illegal jamming.

With this paper our last shreds of privacy are being taken away, but they presented the news with nice background music, so there's that.

The skeletons appear to have very long legs, but no torsos.

I wonder if it was made intentionally that way to make them look less serious.

In a 5-4 decision in https://en.wikipedia.org/wiki/Kyllo_v._United_States , the SCOTUS determined that police can't use thermal imaging on a house without a search warrant. I wonder what the vote would have been if the justices could have seen videos like this.

So this MIT method would be OK, since it's not thermal?

Anecdotally, I've had the same experience. Been going to Home Depot for a number of years, routinely using the app to locate the aisle I want in the store. Starting less than a year ago my signal becomes almost unusably weak as soon as I walk through the doors. No construction on the store, same store as has been there for a decade, but something changed. Might be a coincidence.
