Subliminal Channels in Visual Cryptography
Cryptography, 2022 This paper describes three methods of creating a subliminal channel in visual cryptography that are defined for a (2,2) sharing scheme. They work by hiding additional covert information besides the original encrypted image.

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.

An optimization of color halftone visual cryptography scheme based on Bat algorithm
Journal of Intelligent Systems, 2021 Visual cryptography is a cryptographic technique that allows visual information to be encrypted so that the human optical system can perform the decryption without any cryptographic computation. The halftone visual cryptography scheme (HVCS) is a type of
