Using Wifi to detect concealed carry

[turkeydance]

won Best Paper at 2018 CNC IEEE conference:

In this work, we propose to utilize the finegrained channel state information (CSI) from off-the-shelf WiFi to detect suspicious objects that are suspected to be dangerous (i.e., defined as any metal and liquid object) without penetrating into the user’s privacy through physically opening the baggage. Our suspicious object detection system significantly reduces the deployment cost and is easy to set up in public venues.

"without penetrating into the user’s privacy through physically opening the baggage"

a euphemism sort of like

"your rates will never increase due to age"

"without penetrating into the user’s privacy "

So peering into my shorts isn't "penetration". Hmm. I think what the authors and inventors meant was " Without offending clueless sheeple who think we are on their side".

So now we can look forward to unreasonable search in otherwise undeclared search zones. Beautiful.

And physical search and seizure just a hares breath behind ? Authorized by what ?

If you are examining me or my possessions you are invading my right to privacy, physically or not. It is the action, not the method that determines the result.

May only detect "Smart Guns".

So Ghost Guns won't show up ?

The more I think about it the more I think the technology amounts to constitutional breach.

Can I get one if those RFID wallet protectors in X-TRA large?

I'm already good.

Been wearing foil thongs for years. If there's enough interest on the forum, I may mass produce them.

Chainmail underwear for men (warning: not for the faint of heart, but not NSFW)?

Everyone knows Sumo thong-holsters are only for stainless weapons.

I suppose the next step is to get the Chief to offer a chain mail holster to match?

Something wicked this way comes.

Our suspicious object detection system

Wtf?
This is so highly variable in it's definition that it's beyond absurd.
It doesn't surprise me that gov.co and their private sector enablers try these stunts. What's bothersome is that so many Americans will view this as legit.

detect suspicious objects that are suspected to be dangerous (i.e., defined as any metal and liquid object) without penetrating into the user’s privacy through physically opening the baggage.

It's not that exciting, it just detects signals being tweaked by going through various media and classifies the tweakage. You're not opening the bag, but you are penetrating the crap out of it ('cause that's how radio waves work) so you are searching it in effect. But I can see how running bags though a machine that doesn't notice your giant dildo is safer than having some minimum wage goon checking it out with his eyes.

Not sure it would work on people though, since people are mostly water anyway they'll likely throw off the liquid detection since we mess with radio waves that way.

Our suspicious object detection system...

Wtf?
This is so highly variable in it's definition...

By design...

Keeping things vague at the outset makes it so much easier for .gov to "make up the rules as the game's being played".

 

[SPM]

Could this be used as an off the shelf perimeter monitor? Something that you could set up to alert you that something or someone was, say, lurking on your property, and in general where they were and a general path they were traveling?

We live in a technolog-driven and ever more connected world.

Government, as old as it is, will still always use that technology as a means to power over people.

Always.

So what are the People to do?

A Free People figure out how to minimize the invasive nature of the technology and adapt it to ways it can be used to resist.

 

[georgel]

So many people talk about EMP like it's a bad thing.

I'm messing with Arduino stuff here while I'm laid up. Time for some very cheap active electronic countermeasures....

 

[Bruce333]

Technology already exists...

"... portable scanners, which project waves to do full-body screenings of passengers walking through a station without slowing them down..."

That scene from Total Recall is what I thought of when I first saw the story.

 

[Ikarus1]

until they harass someone with an insulin pump, or some other medical device.....someone who has a great attorney.

 

[Ikarus1]

btw.......most commercial wifi equipment SUCKS until you dolly up the firmware. And even then, it SUCKS. Good luck scanning people without running them single file thru an antenna array.

 

[noway2]

It sounds like it's similar to that back scatter X-ray stuff they use at airports. In this case they're just using RF, which for wifi is commonly around 5GHz, which will have a small enough wave length to get images from the returns.

There was an article a year or so ago about using wifi to map a room. This is just an extension of that.

Of course govt will try to use this to detect people with "contraband" as they no about their business. Stop and frisk done electronically.
