On 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 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...
متن کاملVisual Secret Sharing Scheme using Grayscale Images
Pixel expansion and the quality of the reconstructed secret image has been a major issue of visual secret sharing (VSS) schemes. A number of probabilistic VSS schemes with minimum pixel expansion have been proposed for black and white (binary) secret images. This paper presents a probabilistic (2, 3)-VSS scheme for gray scale images. Its pixel expansion is larger in size but the quality of the ...
متن کاملSecurity Analysis of a Hash-Based Secret Sharing Scheme
Secret sharing schemes perform an important role in protecting se-cret by sharing it among multiple participants. In 1979, (t; n) threshold secret sharing schemes were proposed by Shamir and Blakley independently. In a (t; n) threshold secret sharing scheme a secret can be shared among n partic-ipants such that t or more participants can reconstruct the secret, but it can not be reconstructed b...
متن کاملDynamic Multi-Secret Sharing Scheme
Secret sharing schemes are very important techniques for the key management. To provide more efficient and flexible alternatives for the applications of secret sharing, this paper presents a dynamic multi-secret sharing scheme. A significant characteristic of the proposed scheme is that each participant has to keep only one master secret share which can be used to reconstruct different group se...
