Government may have a system in place to trace paper copies
by Mike Adams, the Health Ranger, NaturalNews Editor
Research conducted by the Electronic Frontier Foundation (EFF), based in San Francisco, suggests that the government may have a deal with laser printer manufacturers to implement encoding systems that would allow the government to track documents to particular machines.
A secret code embedded in many colour laser jet printers allows the US government and any other organisation capable of reading the cipher to identify when the copies were made and on which particular machine, according to research conducted by the Electronic Frontier Foundation (EFF).
The San Francisco-based privacy organisation said it had detected almost invisible patterns of yellow dots on every document printed on the affected machines that could indicate when and where the print was made.
The foundation cautioned that though it had deciphered the code on Xerox machines, it had not done the same for the yellow dots found on other copiers, but that it was likely that they too represented a sophisticated document tracking system.
"So far, we've only broken the code for Xerox DocuColour printers, but we believe that other models from other manufacturers include the same personally identifiable information in their tracking dots," said EFF Staff Technologist Seth David Schoen.
The group said that currently only the US Secret Service and now itself had the ability to decrypt the imprint.
It said that although the Secret Service claims to use this information only for cornering counterfeit crimes, there is no legal framework to prevent the information being put to other uses.
"Underground democracy movements that produce political or religious pamphlets and flyers, like the Russian samizdat of the 1980s, will always need the anonymity of simple paper documents, but this technology makes it easier for governments to find dissenters," said EFF Senior Staff Attorney Lee Tien.
"Even worse, it shows how the government and private industry make backroom deals to weaken our privacy by compromising everyday equipment like printers.
"The logical next question is: what other deals have been or are being made to ensure that our technology rats on us?."
