If I had to guess, they're probably incorporating some of Xerox's DataGlyph technology to make this work. If someone were to digitally alter the image, it'd break the code that stored within the image. Yet at the same time, the image can be printed, snail-mailed, scanned, and then digitally verified that it has not been altered.
Maybe the people on the Nebuchadnezzar in "The Matrix" use this as a training exercise for learning how to watch/read those green screens of binary information - first they start with 56k modems, then they graduate to 10 MB hubs....
