Mac Developer: How a few yellow dots burned the Intercept’s NSA leaker | Ars Technica

How a few yellow dots burned the Intercept’s NSA leaker | Ars Technica: "The watermarks, shown in the image above—an enhancement of the scanned document The Intercept published yesterday—were from a Xerox Docucolor printer. Many printers use this or similar schemes, printing faint yellow dots in a grid pattern on printed documents as a form of steganography, encoding metadata about the document into its hard-copy output. "

A cautionary tale.
