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.

CMY Color Spaced-Based Visual Cryptography Scheme for Secret Sharing of Data
Wireless Communications and Mobile Computing, 2022 Visual cryptography technique allows visual information to be encrypted in such a way that the decrypted information appears as a visual image. Visual cryptography allows digital images to be separate into few shares called transparent shares.

Visual Cryptography Scheme with Essential Participants
Mathematics, 2020 Visual cryptography scheme (VCS) shares a binary secret image into multiple shadows printed on transparencies. Stacking shadows can visually decode the secret image without computational resources. Specifically, a (k, n) threshold VCS ((k, n)-VCS) shares

Verifiable Visual Cryptography [PDF]
2012 Sixth International Conference on Genetic and Evolutionary Computing, 2012 The paper presents a verifiable visual cryptography (VC) scheme for checking the validness to the shares engaged in a VC decoding instance. the idea is to stamp a continuous pattern on the shares belonging to the same secret image, and a part of the pattern can be revealed through aligning and stacking half of two shares together.

Cheating Prevention in Visual Cryptography [PDF]
IEEE Transactions on Image Processing, 2007 Visual cryptography (VC) is a method of encrypting a secret image into shares such that stacking a sufficient number of shares reveals the secret image. Shares are usually presented in transparencies. Each participant holds a transparency. Most of the previous research work on VC focuses on improving two parameters: pixel expansion and contrast.
