>I think NSA/Big Brother ability to store everything and analyze later is a game changer similar to using dogs to search for smells, DNA analysis of everyday life (think paper tissue, drinking cups...) or spectral/chemical analysis of residuals of gun powder, blood or explosives.

Good that you didn't mention traces of narcotics on cash, because it's not evidence of anything for decades now. All the money has it.

>While above methods are partially fine if targeted to human searchers, automatic pattern recognition will make short work of at least some of those attempts.

I kind of remember that Facebook said it will stop using face recognition on uploaded photographs. They even said in which situations they promise not to do it.

>Using several prepaids will soon evoke own patterns, owning some accounts where encrypted mails are sent will be tracked to specific users (just think customer identification already in use...) similar to sometimes or often walking away from/disabling those personal tracking devices :-((

Hidden in plain sight is the way to do it. Just embed a few hundred bytes or a piece of paper with a message into a photograph same as dozens of photos you routinely send to the same people as usual. IOW, be a heisenbug.

p.s. I first wrote "I seem to remember", but that doesn't make sense to me. To know whether I seem this or that way, I have to look at me from a different person. And then I wouldn't know, looking at anybody, how does one look like seeming to remember or like seeming to not remember - I'd never know the difference. What are the telltale signs of remembering (before the "I remember how ..." is said)?
