In this paper, we present a new approach for sharing images between l players by exploiting
the additive and multiplicative homomorphic properties of two well-known public key …

(k, n)-threshold secret image sharing (SIS) protects an image by dividing it into n shadow
images. The secret image will be recovered as we gather k or more shadow images. In …

For visual secret sharing (VSS), general access structure (GAS), which can freely define the
qualified set and the forbidden set, provides dealers the ability to share secret information …

Visual Cryptography (VC) is a powerful technique that combines the notions of perfect
ciphers and secret sharing in cryptography with that of raster graphics. A binary image can …

This paper proposes a visual secret sharing (VSS) scheme with efficient pixel expansion
which prevents malicious share holders from deceiving an honest share holder. A VSS …

A visual secret sharing (VSS) scheme with minimum pixel expansion is proposed to prevent
malicious participants from deceiving an honest participant. A VSS scheme encrypts a secret …

Visual Cryptography (VC) is a powerful technique that combines the notions of perfect
ciphers and secret sharing in cryptography with that of raster graphics. A binary image can …

(k, n)-visual secret sharing scheme ((k, n)-VSSS) is a method to divide a secret image into n
images called shares that enable us to restore the original image by only stacking at least k …

In this chapter, Visually encrypted images are introduced. For visually encrypted images, the
format of input files is image and the format of output files is also image. It is difficult to …

The visual cryptography scheme (VCS) is a scheme which encodes a secret image into
several shares, and only qualified sets of shares can recover the secret image visually, other …
