- Description
- Let P = {1, 2,..., n} be a set of elements called participants. In this paper we construct a visual cryptography scheme (VCS) for the strong access structure specified by the set Γ₀ of all minimal qualified sets, where Γ₀={S : S ⊆ P, 1 ∈ S} and |S| = k}. Any VCS for this strong access structure is called a (k, n)*-VCS. We also obtain bounds for the optimal pixel expansion and optimal relative contrast for a (k, n)*-VCS.
