Is your copier spying on you?
I actually first saw this on January 30th on Fox 5 News Investigates here in Washington, DC. But it's been covered earlier in PC World, on Boing Boing, the E-Media Tidbits blog and -- comprehensively -- on the Web site of the Electronic Frontier Foundation.
Basically, copy machines and printers are now putting invisible (to the naked eye) codes on pages printed or copied indicating what machine made the copy (when codes are entered on the machine), the date and time. Or, for printed documents, which computer the print command came from, date and time.
It's quite a tracing tool...
