The safeguarding of digitized data against unwanted access and modification has become
an issue of utmost importance as a direct result of the rapid development of network …

In a secret image sharing (SIS) scheme, a dealer (the data owner or a trusted third-party)
encodes a secret image into some share images and distributes them among some …

The XOR operation has improved the recovery effect of the visual secret sharing schemes.
Various visual secret sharing schemes based on XOR operation are available in the …

Visual cryptography (VC) is a variant form of secret sharing. In general threshold setting, the
k-out-of-n VC allows that, in a set of n participants, any k can recover and reconstruct the …

The purpose of this paper is to develop an algorithm for sharing k secret images to n
participants in such a way that each participant gets a single share image by encoding all k …

A secret sharing scheme partitions a secret into a set of shares and distributes them among
the eligible participants, with each participant receiving one share of the secret. The sharing …

This paper proposes a simple method for establishing a visual cryptographic (VC) scheme
with the ability to prevent cheating. Given the n base-shares generated in a conventional (t …

Visual cryptography scheme (VCS) is a secret‐sharing scheme which encrypts images as
shares and can decrypt shares without digital devices. Although a participant can reveal the …

Secret sharing is a highly relevant research field, and its application to 2D images has been
thoroughly studied. However, secret sharing schemes have not kept pace with the advances …

A novel random grid and reversible watermarking based verifiable secret sharing scheme
for outsourcing image in cloud is proposed in the paper. In the proposed scheme, data …
