The CIA is tracking all your porn printouts

"Sleuths Crack Tracking Code Discovered in Color Printers". Does this creep anyone else out? Some more pictures of the code.
It gets scarier: "But Seth Schoen, the EFF technologist who led the organization's research, said he had seen the coding on documents produced by printers that were at least 10 years old." So who knows how long this has actually been going on?
Agh damn it. I searched for printer tracking codes, EFF, and checked the links. Sorry about that.

Or even buy a printer with cash from a store in some other state, if you're planning on doing anything scandalous. Of course, now that the code is known, I would imagine it would be better to simply wash your bills, er, 'documents' with a chemical that would turn the entire thing yellow under the right light.

i thought this done for primary purpose of tracking forged paper cash to it's point of origin (newfangled color inkjets and lasers). in which case not that great a deal to get all creeped up about.
and by most accounts wasn't ever really much of a 'secret' either.
why now all the hysterics?

Doesn't matter. As long as a connection can be established between you and any output from that printer, everything else it's put that fingerprint can also be linked back to you. Even if you paid cash.
One of the concerns EFF has raised is how governments can use this to identify anonymous critics/dissidents through their printer's or copier's hidden signature.

er, yes it matters. Paying cash eliminates the paper trail linking you personally to a certain printer.

I don't think anyone is suggesting entry-level inkjets carry this "protection." That would be a bit of overkill. The exact printer in question, a Xerox Docucolor 12, is fairly massive (even without the finisher module, as pictured) and quite expensive. Even most companies rent, rather than buy, these machines. I'd be surprised if any of the other printers the EFF was looking at were less than office-grade.

deadfeather; take a look at the link I posted; the laser control component is in many printers; plenty of which are consumer-grade.
I guess I'm living in the past; I didn't think any color laser printers were consumer-grade. But still, my statement about inkjets still stands, at least for the time being.

I see what you're saying, but I just don't think it's a good point. If you're going to print stuff that identifies you personally anyway why would you give a damn about a secret code that may identify you covertly?

That's rather naive. The drivers can easily enough contain code that spits out little yellow dots onto the page as it prints. And it's not a stretch to imagine a teeny chip that monitors the line feeds and head movements, and spits out little pulses to a yellow nozzle. It'd cost a penny to implement it.

C'mon,people. The problem here is not that these printers spit out secret identification codes (although that's plenty bad).
The problem is the secret collusion between government and business to essentially spy on customers without their knowledge or consent.
Secret dots on printers, hardware DRM on computer chips, black boxes on automobiles. What's next? Will your new refrigerator bust you out to the insurance company for eating too much fat? Will your TV watch you while you watch it? Big Brother is moving in, and all I hear is "baa".

Wasn't there something weird about how the BTK killer was discovered--something to do with his printer being tracked? I never saw a good explanation but recall there was some vague reference to how the document was tracked back to his church.

Wow, that's a really simple code. Would it really have killed the government to announce that this was in place at the time they began it? If counterfeit deterrence is the point, why hide it? Erik Larson said it best in his book The Naked Consumer: history has shown again and again that once technology like this is active, it's only a matter of time before it's put to uses other than intended. Hard to imagine that possibility wasn't on the minds of the folks who tried to keep this relatively quiet.

Paying cash eliminates the paper trail linking you personally to a certain printer.
There isn't any paper trail linking a purchaser to a particular printer in any case. It may be possible to use credit card records to find store records that reveal what model of printer a person bought. But the serial number of the actual unit in question isn't generally recorded when you buy something smaller than an automobile.
This type of tracking is intended to confirm suspicions developed through other means. For example, if Joe Blow has been spending lots of dodgy looking $2 bills lately, and he's been overheard at the bar bragging about how he's printing them at home, then the tracking code is a way to positively match the $2 bills he's been spending with the printer the Secret Service finds in his basement. Joe Blow and his lawyer won't be able to credibly claim that his possession of a printer capable of printing the bills is just a coincidence.
Restricted to this sort of use, the tracking codes probably aren't too bad. But these things do tend to grow in scope. It's not hard to imagine the printer drivers being changed to require online registration, for example, or "phoning home" automatically behind the user's back. Then you've got a paper trail.

According to a report on NPR a few days ago, the tecnology is shifting from dot-patterns (which are easier to detect and interpret) to more subtle methods of encoding serial number, date, etc. in variations in the output.
Someone quoted in that piece also said that similar tech has been in digital cameras for years, to uniquely identify the camera in the pics. I guess they flip a pixel here and there, per some secret algorithm. It might be possible to lose it with manipulations in image software, but presumably this would also reduce photo quality.

With all due respect, this is the tired and shortsighted "if you're not doing anything wrong, you don't have anything to worry about".
Right today could easily be wrong tomorrow, especially if the larger public is complacent. Besides, from a civil rights viewpoint, most things are just not the government's fucking business. You know, "The right of the people to be secure in their persons, houses, papers, and effects...", and all those other pesky rights.
And,BTW, business should never be allowed access to any un-volunteered information.
Sorry for the rant, but while there are many theoretical "slippery slopes", this increasing collaboration of business and government is a slope that is steepening in front of our eyes.
