Secret Image Enhanced Sharing Using Visual Cryptography
Cybernetics and Information Technologies, 2017 In the conventional visual cryptographic scheme, an image is divided into several image shares, which are distributed among the members of a group, and the original image is retrieved by combining the shares of all the members.

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.

ESSVCS: An Enriched Secret Sharing Visual Cryptography [PDF]
, 2014 Visual Cryptography (VC) is a powerful technique that combines the notions of perfect ciphers and secret sharing in cryptography with that of raster graphics. A binary image can be divided into shares that are able to be stacked together so as to approximately recover the original image.

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.
