XOR-ed visual secret sharing scheme with robust and meaningful shadows based on QR codes
Multimedia tools and applications, 2019 Quick response (QR) codes are becoming increasingly popular in various areas of life due to the advantages of the error correction capacity, the ability to be scanned quickly and the capacity to contain meaningful content.

Weighted Secret Image Sharing for a
IEEE Access, 2019 In general, in a secret image sharing (SIS) scheme with a (k, n) threshold, the participants have equal weights, and their shares have the same average light transmission. No share can reveal any information about the secret.

Visual Secret Sharing between Remote Participants
International Journal of Computer Applications, 2014 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 ...

Analysis and design of visual secret sharing scheme for gray image
网络与信息安全学报, 2020 Existing gray visual secret sharing (GVSS) convert the original image into black-white binary image for processing, which causes the pixel information loss problem. For this purpose, a kind of GVSS based on gray superposition was proposed.

Towards Shift Tolerant Visual Secret Sharing Schemes without Pixel Expansion
MATEC Web of Conferences, 2016 Naor and Shamir proposed the visual cryptography in 1995, they encrypted secret image into two meaningless random images, called shares, and it can be decrypted by human vision without any calculations.

A New Visual Multi-Secrets Sharing Scheme by Random Grids
Cryptography, 2018 In (2, 2)-visual secret sharing (VSS) schemes, a common type of (k, n)-threshold VSS schemes, secret information can be decoded directly through only two shares by using a human vision system.

Mathematical biosciences and engineering : MBE, 2019 In this paper, we propose a novel mechanism for QR code security anti-counterfeit based on the fusion of visual secret sharing (VSS) and QR code (called VSSQR scheme), which can greatly improve the security of QR code payment.

THE VISUAL SECRET SHARING SCHEME BASED ON THE RGB COLOR SYSTEM
JUTI: Jurnal Ilmiah Teknologi Informasi, 2017 The visual secret sharing (VSS) scheme is a method to maintain the confidentiality of a se-cret image by sharing it to some number participants. A (k, n) VSS divides the secret images into n parts, that are called shadows ; to recover the secret back, k ...

The (n, n) Visual Multi-Secrets Sharing Scheme with Abilities of OR and XOR Decryption
Engineering ProceedingsNaor and Shamir introduced the fundamental concept of visual cryptography (VC) in 1994. In that model, the secret image is split into two meaningless shares, allowing the secret to be revealed and recognized by the human eye just by superimposing the two
