Efficient and Lossless Polynomial-Based Secret Image Sharing for Color Images
IEEE Access, 2019 In today's era of developed network, it is particularly important to ensure the security of information. Secret image sharing is a kind of secret information protection technology with loss tolerance by sharing a secret image to a number of shadow images.

On Multiplicative Linear Secret Sharing Schemes [PDF]
, 2003 We consider both information-theoretic and cryptographic settings for Multi-Party Computation (MPC), based on the underlying linear secret sharing scheme. Our goal is to study the Monotone Span Program (MSP), that is the result of local multiplication of shares distributed by two given MSPs as well as the access structure that this resulting MSP ...

Self-verifiable Secret Sharing Scheme with Locatability for Halftone Images
, 2014 [[abstract]]Visual cryptography is an image secret sharing scheme used to encrypt the secret image into several meaningless share images. Later on, the secret image can be obtained while stacking the share images with no computations. However, the secret

Block-based progressive visual secret sharing
, 2013 Block-based progressive visual secret sharing (BPVSS) is an encryption technique that utilizes the human visual system to recover a secret image. The recovery method is based on building up different image blocks step by step.

PYTHON IMPLEMENTATION OF VISUAL SECRET SHARING SCHEMES [PDF]
Visual secret sharing schemes (VSS) represent an important concept of visual cryptography. They permit the sharing of a secret image between multiple participants so that only authorized groups can recover the secret.

A Latin square autotopism secret sharing scheme [PDF]
, 2015 We present a novel secret sharing scheme where the secret is an autotopism (a symmetry) of a Latin square. Previously proposed secret sharing schemes involving Latin squares have many drawbacks: (a) Latin squares contain n2 entries, which may be too ...
