Abstract
Several methods of concealing an image in a different hardcopy image are presented. The hidden image is secured since only a spatial digital, or optical, correlator equipped with an undecipherable key function can reveal the concealed image from the visible picture. The techniques and their robustness to noise and distortions are demonstrated.
