A perfect contrast visual cryptography scheme is proposed for the features of the large pixel-expansion and low contrast in VC .The scheme is based on both the perfect black visual cryptography scheme(PBVCS) ,keeping the consis-tency between the reconstructed image and the original image without pixel expansion .And this algorithm is simple and feasi-ble ,easy to operate .
