Multi-secrets visual secret sharing
TL;DR: This paper presents a multi-secrets VSS which is extended from traditional VSS, adopted to generate share images macroblock by macroblock in such a way that multiple secret images are turned into only two share images and decode all the secrets one by one by stacking two of share images in a way of shifting.

An EVCS for Color Images with Real Size Image Recovery and Ideal Contrast Using Bit Plane Encoding
Aarti,Pushpendra K Rajput +1 more
TL;DR: This paper proposes a new (k,n)-threshold image sharing scheme using extended visual cryptography scheme for color images based on bit plane encoding that encrypts a color image in such a way that results of encryption is in the form of shares.
Journal ArticleDOI
Meaningful Share Generation for (2, 2)-Multiple Visual Secret Sharing Scheme Without Pixel Expansion
TL;DR: This paper presents a meta-modelling system that automates the very labor-intensive and therefore time-heavy and expensive and therefore expensive process of manually cataloging and cataloging the data of a hospital patient.
Journal ArticleDOI
Multiple Information Hiding using Cubical Approach on Random Grids
TL;DR: The proposed VSS scheme exploits the geometrical configuration of the cube without distorting any of the secret information embedded on the shares, which increases the capacity of secret communication avoiding the pixel expansion problem and reduces the overhead of storage and communication significantly without compromising on security and authenticity of thesecret information.
Proceedings ArticleDOI
High-Capacity Multi-secret Sharing by Random Grid
TL;DR: This paper proposed a multi-secret sharing scheme by random grids such that the following advantages are obtained: removing the restriction of limited secret images encrypted into two cipher-grids, removing the problem of suffering pixel expansion, and without the need of designing tailor-made codebook.
