Nonlinear Secret Image Sharing Scheme
Over the past decade, most of secret image sharing schemes have been proposed by using Shamir's technique. It is based on a linear combination polynomial arithmetic. Although Shamir's technique based secret image sharing schemes are efficient and scalable for various environments, there exists a security threat such as Tompa-Woll attack. Renvall and Ding proposed a new secret sharing technique ...
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 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 کاملA Novel (2,n) Secret Image Sharing Scheme
In this paper, we propose a novel and simple (2, n) secret sharing scheme with precise reconstruction for grayscale, binary and color image. The share construction phase is based on pixel division and XOR operation. The reconstruction is based on XOR and OR operation. The proposed scheme has no pixel expansion and can reconstruct the secret image precisely. This scheme can be directly applied t...
متن کاملA New (k, n) Secret Image Sharing Scheme (SISS)
In this paper, a new (k, n) threshold Secret Image Sharing Scheme (SISS) is proposed. In the proposed scheme the secret image is first partitioned into several non-overlapping blocks of k pixels. Every k pixel is assumed as the vertices of a complete graph G. Each spanning tree of G is represented by k pixels along with Prüfer sequence and used to form k pixels of a share image. The original se...
