I fail to see how this is a fantastic breakthrough in technology, but to each his own. Fujitsu has been working on technology where secret messages can be stored in print and read by a camera phone. It works by skewing a yellow hue in the picture and using a camera phone with a Java application to decipher the information. Up to 12-bytes can be encoded and embedded in a picture and sources say that the first applications of the technology will be for promotions and contests.
