Beating the unique identifiers that printers can add to documents for security purposes is possible: you just need to add extra dots beyond those that security tools already add. The trick is knowing where to add them.
[...] researchers from the Technical University of Dresden [...] Timo Richter, Stephan Escher, Dagmar Schönfeld, and Thorsten Strufe reckon they've cracked the challenge of knowing how to anonymise printed documents, and presented their work to the Association of Computer Machinery's 6th ACM Workshop on Information Hiding and Multimedia Security in Innsbruck, Austria [the week of June 22].
In this paper, the TU Dresden researchers explain that they tested 1,286 documents printed on machines from 18 manufacturers, creating an extraction algorithm to identify well-known dot-patterns--and at the same time, discovering four previously undiscovered patterns coding at 48, 64, 69, and 98 bits.
Identifying new patterns is important, from a privacy point of view, since as the authors points out, an activist in a dictatorship could easily be unmasked by their printer (unless they happen to use a Brother, Samsung, or Tektronix printer, none of which seemed to carry tracking codes, the researchers said).
[...] The group has published [a] toolkit that automates the obfuscation workflow, here.

OMG. I get messages exactly like this about twice a week.
It's always the same. I've put a virus on your computer and caught your wanking on webcam. I'm going to share it with all your contacts unless you send me $$ in bitcoin. The last one was for $500 worth.
I've never been complimented on my choice of wanking material however. Martyb, what have you been watching...

False alarm, it was just videos censored from YouTube. :/

I haven't yet, but I would laugh my fucking ass off.
The major point being, we already know martyb is a dirty fucking pervert that gets home, drops hit pants, and whacks it furiously. Ever see bandwidth graphs from the major porn providers? Looks very similar to peak electricity usage graphs, with one part of the day being extremely active. Reminds of the Johnson & Johnson study. 99% of men and boys admitted to masturbation. The other 1% lied :)
At this point in our society, who even cares about who watches porn? Some religious fundamentalists that are quickly becoming irrelevant? What would hurt Martyb more is if he came out as an Alt-right supporter and loudly claimed support for incarcerating children in concentration camps. They're would be pitchforks and torches handed out by the Left with calls to get him fired, evicted, .etc. That's not a barb thrown at the Left either, but just an observation that people live annihilating people these days with no mercy. Where's Roseanne now? I loved that whacky bitch. She's funny and the show was watchable.
Anyhoo, nobody cares about that shit anymore, and most adults are not even embarrassed about it.
Tell them to release all the data, and not to get your name wrong for the history books :)
Technically, lunchtime is at any moment. It's just a wave function.

So many guys can thank Johnson & Johnson for studying that. Because their Johnson's baby lotion is PERFECTO. No more blindness, no more hairy palms!!
