Abstract

This paper presents a visual cryptography scheme with meaningful shares for general access structure,called extended visual cryptography scheme(EVCS),by means of matrices concatenation,and the pixel expansion is obtained.A color extended visual cryptography scheme for general access structure is constructed,and the optimal pixel expansion for color (k,n)-EVCS is obtained as well.
