Visual cryptography is a special type of secret sharing. Two models of visual cryptography have been independently studied: deterministic visual cryptography, random grid visual cryptography, introduced by the researchers. In the context of the deterministic model, the researcher has introduced a third model, the probabilistic visual cryptography model. The connection between the probabilistic and the deterministic models has been explored. In this paper the authors show that there is a strict relation between the random grid model and the deterministic model.
