Visual Secret Sharing between Remote Participants
Visual cryptography and random grids are forms of visual secret sharing that encrypt a secret image into indecipherable shares. Decryption occurs by printing them onto transparencies and stacking, but this requires participants to be in the physical presence of each other, so this paper addresses the use of visual secret sharing between remote, incommunicado agents. To this end, a prototype app...
متن کاملOn Converting Secret Sharing Scheme to Visual Secret Sharing Scheme
Traditional Secret Sharing (SS) schemes reconstruct secret exactly the same as the original one but involve complex computation. Visual Secret Sharing (VSS) schemes decode the secret without computation, but each share is m times as big as the original and the quality of the reconstructed secret image is reduced. Probabilistic visual secret sharing (Prob.VSS) schemes for a binary image use only...
متن کاملMulti-Threshold Visual Secret Sharing
Visual cryptography (VC) has been developed extensively based on its practicability. These schemes can encode a black-and-white secret image into several shadow images, and, by stacking a certain number of shadow images, can retrieve the secret image through the human visual system. In this paper, we employ Hsu et al.’s ideal multi-threshold secret sharing scheme based on monotone span programs...
متن کاملCheating Human Vision in Visual Secret Sharing
Visual Secret Sharing (VSS), first introduced by Naor and Shamir, is a variant form of secret sharing; especially, secret decoding is stacking shares together without performing any complicated cryptographic computation. The recovered secret is visible by human vision system (HVS). However, Horng et al. showed cheating is possible in VSS, which is inspired from cheating in secret sharing. Since...
متن کاملVisual secret sharing scheme with autostereogram
Visual secret sharing scheme (VSSS) is a secret sharing method which decodes the secret by using the contrast ability of the human visual system. Autostereogram is a single two dimensional (2D) image which becomes a virtual three dimensional (3D) image when viewed with proper eye convergence or divergence. Combing the two technologies via human vision, this paper presents a new visual secret sh...
