Fujitsu is developing a technology that would allow for hidden messages to be printed within images printed on paper. The information could then only be decoded by a mobile phone or digital camera.
The technology works by taking advantage of the human eye’s issues with the color yellow. The yellow hue in the image could be manipulated to hide messages or some other data. To the naked eye, the image would look completely normal. When viewed with a specially enhanced digital camera or phone, however, the digitized hiodden image would reveal itself.
Fujitsu beleives this new technology will work well in publishing, particularly with marketing ventures. Companies could easily use the technique to hide coupons for store discounts or access codes for special online features - like free MP3 downloads.

This might help the industry evolve and create a standard.
