A Novel Pixel Merging-Based Lossless Recovery Algorithm for Basic Matrix VSS
Lossless recovery in visual secret share (VSS) is very meaningful. In this paper, a novel lossless recovery algorithm for the basic matrix VSS is proposed. The secret image is reconstructed losslessly by using simple exclusive XOR operation and merging pixel.

Tamper Detection and Recovery for Medical Images Using Near-lossless Information Hiding Technique [PDF]
Digital medical images are very easy to be modified for illegal purposes. For example, microcalcification in mammography is an important diagnostic clue, and it can be wiped off intentionally for insurance purposes or added intentionally into a normal mammography.

Weighted Polynomial-Based Secret Image Sharing Scheme with Lossless Recovery [PDF]
In some particular scenes, the shadows need to be given different weights to represent the participants’ status or importance. And during the reconstruction, participants with different weights obtain various quality reconstructed images. However, the existing schemes based on visual secret sharing (VSS) and the Chinese remainder theorem (CRT) have ...

A ( k , n ) threshold secret image sharing (SIS) method is proposed to divide a secret image into n shadows. The beauty of this scheme is that one can only reconstruct a secret image with k or more than k shadows, but one cannot obtain any ...

A Secret Image Sharing Based on Logistic-Chebyshev Chaotic Map and Chinese Remainder Theorem [PDF]
Visual secret sharing (VSS) was introduced in order to solve information security issues. It is a modern cryptographic technique. It involves breaking up a secret image into $n$ secured components known as shares.
