A secure Boolean-based multi-secret image sharing scheme

Journal of Systems and Software, 2014
Abstract An (n, n) multi-secret image sharing scheme shares n secret images among n shared images. In this type of schemes, n shared images can be used to recover all n secret images, but the loss of any shared image prevents the recovery of any secret image.

A Threshold Multi-secret Sharing Scheme

2008 IEEE International Conference on Networking, Sensing and Control, 2008
This paper proposes a threshold multi-secret sharing scheme. In such a scheme, many secrets are shared in such a way that all secrets can be reconstructed independently without refreshing the shares. Every share is of the same size as that of any single shared secret in the proposed scheme.

Linear multi-secret sharing schemes

Science in China Series F, 2005
In this paper the linear multi-secret sharing schemes are studied by using monotone span programs. A relation between computing monotone Boolean functions by using monotone span programs and realizing multi-access structures by using linear multi-secret sharing schemes is shown.

Sharing visual multi-secrets using circle shares

Computer Standards & Interfaces, 2005
Traditional visual cryptography technique has provided sufficient security to fulfill the purpose of protecting confidential messages. In current technology, the same set of shares can be embedded with many sets of secret messages after one of the shares is rotated at different degrees.

Multi-secret sharing threshold access structure

2015 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2015
This paper proposes threshold access structure for multi-secret sharing. It uses a two-level encoding for share generation from multiple secret images. In the first level of encoding secure Boolean based operations are used. The second level of encoding uses Chinese remainder theorem and Lagrange Interpolation. It is mainly useful for secure encryption

Sharing Multi-Secret Based on Circle Properties

2008 International Conference on Computational Intelligence and Security, 2008
A (t, n) threshold multi-secret sharing scheme based on the properties of a circle in multi-dimensional space is proposed in this paper. Only t or more shadows can reconstruct the secrets; while any less than t shadows cannot obtain any information of the secrets.

Efficient collusion resistant multi-secret image sharing

Multimedia Tools and Applications, 2020
Multi-secret image sharing techniques (MSS) extend the secret image sharing schemes. The paper reports a novel MSS scheme designed to be collusion resistant. It starts with a brief introduction of the concept thereafter discussing the related works in the domain. Security is an implicit requirement for MSS techniques.

Multi secret sharing with unexpanded meaningful shares

Multimedia Tools and Applications, 2017
Traditional Visual Cryptography (VC) facilitates a technique to protect only one secret image using single set of shares. Recent researches enhance the capabilities of traditional VC by providing the feature of Multi Secret Sharing (MSS), where more than one secret image can be protected at a time.
