Sharing a Secret Image in Binary Images with Verification

  title={Sharing a Secret Image in Binary Images with Verification},
  author={Zhi-Hui Wang and Chin-Chen Chang and Huynh Ngoc Tu},
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… CONTINUE READING
