A new method for Visual Secret Sharing
Hamed Firouzi, Mohammad Ehdaie, Mohammad Reza Aref · 2008
In this paper a new probabilistic view to the visual secret sharing (VSS) is presented and as a result, a new VSS scheme is proposed. The proposed scheme is a threshold scheme with perfect black pixel reconstruction. We present the scheme by introducing two sets C0and C1. We consider an unknown probability distribution on the elements of C0and C1. Perfectness provides some linear constraints on the probabilities of C0and C1elements. By solving the provided system of linear equations, the probability distributions are specified and we achieve a perfect VSS scheme.
