A new method for Visual Secret Sharing
2008 International Symposium on Telecommunications, 2008In this paper a new probabilistic view to the visual secret sharing (VSS) is presented and as a result, a new VSS scheme is proposed. The proposed scheme is a threshold scheme with perfect black pixel reconstruction. We present the scheme by introducing two sets C0 and C1.

Visual multi-secret sharing with friendliness
Journal of Shanghai Jiaotong University (Science), 2014Visual secret sharing (VSS) was used in the literature to encode and decode secret images until visual multi-secret sharing (VMSS) was proposed. Distinctly, multiple secret images can be encoded or decoded at a time in VMSS; however, only one secret image can be done in VSS.

Progressive Visual Secret Sharing with Multiple Decryptions and Unexpanded Shares
2015Differently from traditional secret sharing, progressive and perceptual secret sharing can gain clearer recovered secret image with more shares. Recently, Hou and Quan proposed a progressive visual secret sharing (PVSS) scheme that solves the pixel expansion problem of previous research.

Visual secret sharing watermarking for digital image
Informatica (Slovenia), 2002Summary: A visual secret sharing watermarking technique is proposed as a way of solving copyright protection problems for digital images. The proposed watermarking technique employs a visual secret sharing scheme and separates the watermark into two parts, a public watermark and a secret watermark.

Boolean Composition of Visual Secret Sharing Schemes
2012In this paper, we analyze the disjunction and the conjunction of two access structures for visual secret sharing schemes. The latter operation, when applied to k-out-of-n schemes, leads to schemes with multiple thresholds. We precisely determine the maximum relative contrast for schemes of this type.

Secret Sharing, Visual Cryptography, and Voting
2018Suppose you have n people, with whom you wish to share a secret. However, you do not wish to entrust any of them individually with the secret. Rather, you only want to allow them to learn what the secret is when a significant coalition of the people, at least k, say, work together to learn it.
