Abstract:-The visual cryptography (VC) is a secret sharing scheme where a secret image is encoded into
transparencies, and the stacking of any out of transparencies reveals the secret image. The stacking of or fewer
transparencies is unable to extract any information about the secret. We discuss the additions and deletions of users
in a dynamic user group. To reduce the overhead of generating and distributing transparencies in user changes, this
paper proposes a VC scheme with unlimited based on the probabilistic model. The proposed scheme allows to
change dynamically in order to include new transparencies without regenerating and redistributing the original
transparencies. Specifically, an extended VC scheme based on basis matrices and a probabilistic model is proposed.
An equation is derived from the fundamental definitions of the VC scheme, and then the VC scheme achieving
maximal contrast can be designed by using the derived equation.
