A lossless image secret sharing using a simple Boolean operation is proposed. The concept of visual cryptography in the secret sharing scheme is used to redesign a lossless secret sharing scheme. To ensure that the reconstructed image is the true secret image, an authentication mechanism is imported into the proposed scheme to verify whether the shadows are authentic before reconstructing the secret image. The proposed scheme delivers much more effective performance than Chen and Wu’s scheme.
