Yellow Dots of Mystery. Is Your Printer Spying on You?
FW: June 20, 2014
Imagine that every time you print a document, it automatically includes a secret code that could be used to identify the printer.. and, potentially, the person who used it. Sounds like something from a spy movie, right?
Unfortunately, the scenario is'nt fictional. Most color laser priners and color copiers are designed to print invisible tracking codes across every singe printed page of their output. These codes reveal which machine produced a document and, in some cases, when the document was printed or copied.
