Color Laser Printers Tracking Everything You Print
It's not new, but it's getting noticed: Jordan writes "Yahoo! News is reporting that several printer manufacturers are now and have been for some time embedding (nearly) invisible serial numbers in every document you print with their color laser printers, allowing law enforcement to track any such document back to the printer which printed it. The technology, ostensibly created to track down money counterfeiters, was created by Xerox about 20 years ago. A Xerox researcher says that the number-embedding chip lies 'way in the machine, right near the laser' and that 'standard mischief won't get you around it.'"
Please refer to:
TALLEY v. CALIFORNIA, 362 U.S. 60 (1960)
McIntyre v. Ohio Elections Comm'n (93-986), 514 U.S. 334 (1995)
Very relevant is the quote from McIntyre:
While one can reasonably question anonymity as a "universal" right applicable in all times under all conditions, these times should be the exception rather than the rule with the burden falling on those who say that the restriction should apply rather than on those who say not.
If the g'vt kept the data on you that google does you'd better believe you'd be calling it "doing evil"
