Secret image sharing with smaller shadow images

  title={Secret image sharing with smaller shadow images},
  author={Ran-Zan Wang and Chin-Hui Su},
  journal={Pattern Recognition Letters},
Secret image sharing is a technique for protecting images that involves the dispersion of the secret image into many shadow images. This endows the method with a higher tolerance against data corruption or loss than other image-protection mechanisms, such as encryption or steganography. In the method proposed in this study, the difference image of the secret image is encoded using Huffman coding scheme, and the arithmetic calculations of the sharing functions are evaluated in a power-of-two… CONTINUE READING
