- Description
- Let G =(V,E) be a graph without isolated vertices. Let Γ(G) denote the strong access structure whose basis is the edge set E and let m∗(G) denote the optimal pixel expansion of a visual cryptography scheme for Γ(G). In this paper we obtain a characterization of all connected graphs G with m∗(G) = 3.
