An overview of visual cryptography techniques
Multimedia Tools and Applications, 2021Visual cryptography is an encryption technique that decomposes secret images into multiple shares. These shares are digitally or physically overlapped to recover the original image, negating the need for complex mathematical operations or additional hardware.

Applications of visual cryptography
International Journal of Parallel, Emergent and Distributed Systems, 2011Visual cryptography is a secret sharing scheme with only few known applications. This paper first modifies visual cryptography techniques to make them suitable for applications and then proposes some applications that use the modified techniques. These applications are secured communication system that are used to broadcast one or more secrets, multi ...

Visual cryptography encodes a secret binary image (SI) into n shares of random binary patterns. If the shares are xeroxed onto transparencies, the secret image can be visually decoded by superimposing a qualified subset of transparencies, but no secret information can be obtained from the superposition of a forbidden subset.

Braille for Visual Cryptography
2014 IEEE International Symposium on Multimedia, 2014Visual Cryptography (VC) has been studied as a significant way of information security. In VC, original secret is divided into two images called shares. VC shares show no clue for secret perceptually, whereas participants are able to obtain the secret by simply superimposing the shares. Despite the obvious advantages of VC in crucial secret protection,

IEEE Signal Processing Letters, 2011
This letter presents a method for implementing visual cryptography (VC) in which an additional tag is attached to each generated share. The proposed (t, n), 2 ≤ t ≤ n tagged visual cryptography (TVC) scheme works like a traditional VC scheme does, where the original image is encoded in n shares in such a way that the secret can be revealed by ...
