This is beyond awesome. Steganography is the artÂ of hidingÂ something in something else. It is most often used to refer to hiding information in digital images in such a way that the image is not altered to the human eye. This is useful because viewersÂ don’t know there is an encrypted message in the image as they would if theyÂ looked at encryptedÂ text.
Some crazy kids have worked out (theoretically) how to useÂ flavour additives to do food steganographyÂ (PDF).Â Just imagine if it was easy to get people to eat their greens, make the cat take a pill, etc.
