Remember those alleged, NSA-leaked classified documents in the news? They were tracked back to Reality Winner—an NSA contractor—by codes put into the printed documents that identified the source.
According to The Atlantic magazine, when The Intercept news outlet asked the NSA to verify documents sent to them, the FBI was able to track the leak back to Winner from the steganography coding (encoded watermarks) left by NSA’s Xerox DocuColor printer. Those classified documents were printed on the DocuColor & then sent to the news outlet.
