The Yellow Dot Matrix
How Your Printer Secretly Spies on You and How to Protect Yourself
Next time you print a document in the privacy of your home, be it a love letter, resignation, or a political manifesto. You think it's private, ink on paper in your private space, but hidden within that document is a surveillance system so subtle, you’ll never know it’s there unless someone tells you. Your color printer is embedding invisible yellow tracking codes into every document you print. And those codes can be used to trace your printouts directly back to you; confirmed and quietly deployed surveillance technology.
