ABSTRACT:
A method of hiding a first image in a second image to produce a combined image includes the steps of: a) modifying the first image according to the content of the second image, so that when the modified first image is added to the second image to produce the combined image, no visible differences will exist between the second image and the combined image; and b) adding the modified first image to the second image to produce the combined image.
