Sleuths Crack Tracking Code Discovered in Color Printers

It sounds like a conspiracy theory, but it isn’t. The pages coming out of your color printer may contain hidden information that could be used to track you down if you ever cross the U.S. government.

Last year, an article in PC World magazine pointed out that printouts from many color laser printers contained yellow dots scattered across the page, viewable only with a special kind of flashlight. The article quoted a senior researcher at Xerox Corp. as saying the dots contain information useful to law-enforcement authorities, a secret digital “license tag” for tracking down criminals.

Simple solution. Write it by hand or use a black ink printer. Or, have some fun, make a template that will run through your printer that holds the bill. A slot in the template will allow your message to print, but all other ink sprayed by the printer winds up on your template.

So, I guess, now you need a new printer. Bought with cash while wearing a ski mask.
