Snooping has been a common subject with the media recently, but realistically, 
as long as I'm not breaking any laws or post nude pictures of myself on the 
cloud, what do I care if someone is snooping my cell phone? What real harm can 
come of it?

And I'm not talking about skilled hackers finding out my PIN number, because 
they can do that regardless, but what about all the normal snooping going on 
with cell phone apps such as my phone knowing what route I take to work every 
day, or what stores I frequent, or what gas stations I go to. What do I care?

Snooping just poked it's little head into my life recently. There are about a 
bazillion people monitoring, or capable of monitoring,  you,  Apple, Samsung, 
NSA, local police, etc. And even though I knew it was being done I posted a 
picture to social media that was taken by someone else. The app I was using 
asked where it was taken. Even thought I had never been to the particular 
location myself and was physically about 300 miles from that location the app 
listed several places that were nearby and central to where the picture was 
actually taken. Yoicks!

Oh did I mention Microsoft? :) (Actually I don't know about Microsoft Ted - 
primarily pulling your chain this morning)

Subject: Re: [PSES] RF shielding in clothing.


I'm curious if users of these shielding pockets will discover the law of 
unintended consequences. If a cell phone is placed in the pocket, it will have 
trouble picking up the signal from any cell towers. The phone will boost its 
transmit power and my try linking to the towers more frequently. I find that my 
phone's battery is drained much faster in areas with fringe reception. Users of 
this shielded pocket may find that their battery is dead when they retrieve 
their phone.



Of course, this just bring up the question of why people don't turn off their 
phone if they are worried about snooping. Even if you use the pocket, your 
phone has to be pulled out and exposed to be used.



On a related note, this article may have been posted before but it has some 
relation to the subject at hand.

I doubt that braided shields made of such fine filaments would be mechanically 
strong enough. Semi-rigid coax does pretty well, I believe, with one solid 
shield.
