The Electronic Frontier Foundation has revealed which printer manufacturers have complied with the US Secret Service to encode pages with identifying information. It will also take the next step to finding out what spying printers are revealing.
Last week the EFF announced it would able to break a code hidden in tiny tracking dots that some colour laser printers secrete in every document they print. The US Secret Service admitted to having struck a deal with some laser printer manufacturers to add tracking information to the printed matter. The “spooks” claiming it’s a means of identifying counterfeiters.
However, the nature of the private information encoded in each document was not previously known.
The manufacturer with some printer models identified with spy dots include; Brother, Canon, Dell, Epson Aculaser, Konika/Minolta, Kyocera, Lanier, Ricoh, Savin, Tektronix and Xerox. A comprehensive list detailing the model number can be found at the EFF site.
Although the American Civil Liberties recently issued a report revealing what the FBI has amassed against organisations, as well as documenting non-violent groups including Greenpeace and United for Peace and Justice. The EFT is also gathering information about what printers are revealing and how. It has also filed a ‘Freedom of Information Act Request.
