摘要:Conventional visual cryptography methods divide a secret digital image into n pieces and distribute them to n participants. This paper proposes a novel approach to visual cryptography for binary images that includes the capabilities of watermarking and verification. The proposed method allows an n n watermark image to be embedded into an n n secret image to construct two shadows and then to be used to verify the accuracy of the reconstructed image. Checking to determine the reliability of all shadows before they are used to recover the secret image prevents a participant from incidentally or deliberately providing invalid data. Moreover, our proposed method has low computation requirements, so it is suitable for real-time applications. ? 2011.
