Constructions and bounds for visual cryptography

1996
A visual cryptography scheme for a set P of n participants is a method to encode a secret image SI into n images in such a way that any participant in P receives one image and only qualified subsets of participants can “visually” recover the secret image, but non-qualified sets of participants have no information, in an information theoretical sense ...
