Druck als Sypware
Die Electronic Frontier Foundation greift einen Artikel der PCWorld auf in dem berichtet wird, dass einige Druckerhersteller die Seriennummer und den Herstellercode in jeden Farbausdruck codieren.
Peter Crean, a senior research fellow at Xerox, says his company’s laser printers, copiers and multifunction workstations, such as its WorkCentre Pro series, put the “serial number of each machine coded in little yellow dots” in every printout. The millimeter-sized dots appear about every inch on a page, nestled within the printed words and margins.
Dieses Vorgehen soll Fälschungen erschweren, bzw es den Behörden ermöglichen die Fälscher zu identifizieren - die Konsequenzen für die Provatsphäre wurden dabei ausgeblendet.
Auf der Seite Investigating Machine Identification Code Technology in Color Laser Printers gibt die EFF weitergehende Informationen zu diesem Thema.
