Abstract Traditional Visual Cryptography (VC) facilitates a technique to protect only one
secret image using single set of shares. Recent researches enhance the capabilities of …

In (2, 2)-visual secret sharing (VSS) schemes, a common type of (k, n)-threshold VSS
schemes, secret information can be decoded directly through only two shares by using a …

In today's world handling and security of information from attacks becomes very important
aspect for the individuals. Researchers are innovating new techniques to secure the …

Secret-sharing techniques have become increasingly sophisticated over the years and now
focus on generating random shares. These shares do not provide an attacker with any …

Multi-level secret image sharing is a scheme combining hierarchical shadows with
progressive reconstruction. But in previous schemes, the generated shadows are divided …

Conventional visual secret sharing (VSS) scheme encodes a secret image into noise-like
images, called as meaningless shares. Sharing capacity of VSS schemes is increased by …

As a classical secret sharing technique,(k, n) threshold secret image sharing mainly contains
the shadow generation phase and the image reconstruction phase. The sensitive secret …

Aim: In visual cryptography, a secret image is encrypted into two meaningless random
images called shares. These two shares can be stacked to recover the secret image without …

Cyber-attack is a category of attack that uses malicious code for intentionally altering the
computer data, exploiting computer systems and networks, which might result in disruptive …

In the present era, the data has become the most important asset for an individual,
community and organization. Data handling and protection from attacks has become a key …
