| 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. |
