Literature Review on a Natural Image Based VSS Scheme for Sharing Secret Image

Priya K. Rahangdale, A. N. Jaiswal

Abstract: Conventional visual secret sharing scheme hide secret images in shares they are either printed or in digital form. Meaningful images or noise like pixels are appear due to hiding secret image in shares, but during the transmission of share it will increase interception risk. Hence visual secret sharing scheme suffer from transmission risk problem. To solve this problem author proposed a natural image based visual secret sharing scheme. In that secret images are transferred through various media to secure the secret and participant also. The proposed natural image based visual secret sharing scheme can transmit one digital image or printed image and noise like share over n-1 natural shares. The natural images may be in printed or in digital form. Natural image is a combination of printed and digital image. Natural image and printed image generate one noise like share. The unaltered natural shares are different, thus reducing the transmission risk problem.
