I'm confused about why people consistently think that this was a total secret, no matter how many waves of press coverage it gets. https://en.wikipedia.org/wiki/Printer_steganography There were press articles about it by 2004 (and I think some earlier), we had written the tool that Rob Graham used to decode these scans by 2005, and I gave a number of TV interviews about it during 2005. A small number of manufacturers (maybe worried about European data protection laws) also alluded to the existence of the technology in their user manuals. Some of the people from industry who contacted me also said that this was common knowledge to people in the printing industry since at least the turn of the millennium. |

Generally, anything that less than half of the population knows abut is a secret (e.g., menstruation is still called a "secret" in some circles...), so you shouldn't be confused, just disappointed at how gullible / uninformed the average person is.
