r84x writes “A research team led by the Electronic Frontier Foundation
(EFF) recently broke the code behind tiny tracking dots that some color
laser printers secretly hide in every document. The U.S. Secret Service
admitted that the tracking information is part of a deal struck with
selected color laser printer manufacturers, ostensibly to identify
counterfeiters. However, the nature of the private information encoded
in each document was not previously known. “We've found that the dots
from at least one line of printers encode the date and time your
document was printed, as well as the serial number of the printer,”
said EFF Staff Technologist Seth David Schoen.” [Slashdot] [Privacy Digest: Privacy News (Civil Rights, Encryption, Free Speech, Cryptography)]
