General Meaningful Shadow Construction in Secret Image Sharing
IEEE Access, 2018 Secret image sharing (SIS) is an important technique for image protection. Several shadows are produced in SIS through scrambling pixel values and their correlations of a secret image.

Emerging Trends in Visual Secret Sharing
International Journal of Engineering & Technology, 2018 Visual Secret Sharing (VSS) is an increased applicability of traditional secret sharing. In VSS, the secret information is recovered by human visual system or lightweight computational device. There are two models available in VSS, one is Visual Cryptography (VC) which is introduced by Naor's in 1994 and other is a Random Grid (RG) based VSS which is ...

A reversible and lossless secret image sharing scheme with authentication for color images
Journal of King Saud University: Computer and Information Sciences, 2023 With the increasing concern for public privacy protection, Secret Image Sharing (SIS) has garnered significant attention among researchers. The goal of SIS is to split a secret image into multiple shadows, rendering it unrecoverable unless a specific ...

XOR-Based (n, n) Visual Cryptography Schemes for Grayscale or Color Images with Meaningful Shares
Applied Sciences, 2022 XOR-based Visual Cryptography Scheme (XOR-based VCS) is a method of secret image sharing. The principle of XOR-based VCS is to encrypt a secret image into several encrypted images, called shares.

Visual Cryptography Vs Bit Level Secret Sharing For Image Encryption [PDF]
Engineering and Technology Journal, 2010 Secret sharing is a scheme used to distribute secret among a group of users.Rather than making duplicated copies of secrets among users, the secret is dividedinto a number of pieces, called shares.

A (k, n)-Threshold Progressive Visual Secret Sharing without Expansion
Cryptography, 2018 Visual cryptography (VC) encrypts a secret image into n shares (transparency). As such, we cannot see any information from any one share, and the original image is decrypted by stacking all of the shares.

Secret Sharing and Visual Cryptography Schemes [PDF]
, 2001 A secret sharing scheme is a method for sharing a secret among a set P of n participants. The secret is encoded into n pieces called shares each of which is given to a distinct participant. Certain qualified subsets of participants can recover the secret by pooling together their information, whereas forbidden subsets of participants have no ...
