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.

An Approach for Securing QR code using Cryptography and Visual Cryptography
2022 International Conference on Computational Intelligence and Sustainable Engineering Solutions (CISES), 2022Quick Response code (QR code) is a 2-D matrix barcode which stores data in four different encoding modes (numeric, alphanumeric, kanji, binary). They are widely used nowadays and can be seen almost everywhere whether it is on cosmetics products, general ...

Enhancing Security of Image Steganography Using Visual Cryptography
2021 2nd International Conference on Robotics, Electrical and Signal Processing Techniques (ICREST), 2021Steganography is the art of hiding secret data in a medium whereas visual-cryptography is a cryptographic technique where a full image is encrypted. The security of image steganography depends on the secret key set which is used for embedding the secret ...

Probabilistic Visual Cryptography Schemes
The Computer Journal, 2005Visual cryptography schemes allow the encoding of a secret image, consisting of black or white pixels, into n shares which are distributed to the participants. The shares are such that only qualified subsets of participants can 'visually' recover the secret image.

Size Invariant Visual Cryptography Schemes With Evolving Threshold Access Structures
IEEE transactions on multimediaIn this research, we consider the evolving threshold access structure, denoted as $(k, \infty)$, for size invariant visual cryptography scheme (SIVCS). The so-called $(k, \infty)$ threshold indicates the number of participants is supposed to be infinite ...

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 ...
