Asymptotically ideal Chinese remainder theorem ‐based secret sharing schemes for multilevel and compartmented access structures

IET Information Security, 2021
Multilevel and compartmented access structures are two important classes of access structures where participants are grouped into levels/compartments with different degrees of trust and privileges.

Identifiable Tampering Multi-Carrier Image Information Hiding Algorithm Based on Compressed Sensing

IEEE Access, 2020
Aiming at the security problem of secret information preprocessing and the difficulty of improving the capacity and robustness of the single-carrier image information hiding algorithm, an identifiable tampering multi-carrier image information hiding ...

Steganographic Secret Sharing With GAN-Based Face Synthesis and Morphing for Trustworthy Authentication in IoT

IEEE Access, 2021
Trust and security are fundamental to the successful adoption of the Internet of Things (IoT). This paper proposes a secure message authentication scheme based on steganographic secret sharing for building trust in IoT systems. In our scheme, the message

Exploiting compressed sensing and polynomial-based progressive secret image sharing for visually secure image selection encryption with authentication

Journal of King Saud University: Computer and Information Sciences, 2022
Image encryption is an effective method to protect private images by converting them into meaningless ones, but many current image encryption algorithms still have security and efficiency problems.

DNA Based Multi-secret Image Sharing

Procedia Computer Science, 2015
AbstractMultiple secret sharing algorithm using the YCH scheme, combined with DNA encoding is proposed, focusing at better security. Firstly, DNA encoding for multiple images is carried out; then the addition of these encoded components by DNA is performed.

Tamper-proof secret image-sharing scheme for identifying cheated secret keys and shared images [PDF]

, 2013
A (t,n) secret image-sharing scheme shares a secret image to n participants, and the t users recover the image. During the recovery procedure of a conventional secret image-sharing scheme, cheaters may use counterfeit secret keys or modified shared ...

Size-Invariant Visual Cryptography With Improved Perceptual Quality for Grayscale Image

IEEE Access, 2020
The reconstructed image of the size-invariant visual cryptography (VC) is inevitably accompanied by the loss of secret image information and the degradation of perceptual quality.

Ideal Secret Sharing Schemes with Share Selectability [PDF]

, 2011
In this paper, we investigate a new concept, called share selectable secret sharing, where no unauthorized set can obtain information of the secret (in the information-theoretic sense) even if shares are selectable as arbitrary values which are ...

An Extended Multi-secret Images Sharing Scheme Based on Boolean Operation [PDF]

, 2013
An extended multi-secret images scheme based on Boolean operation is proposed, which is used to encrypt secret images with different dimensions to generate share images with the same dimension. The proposed scheme can deal with grayscale, color, and the mixed condition of grayscale and color images.

A Privilege-based Visual Secret Sharing Model [PDF]

, 2016
In traditional visual secret sharing (VSS) schemes, every transparency has the same capability for recovery of the secret image. This means that managers are unable to assign an appropriate privilege to participants according to their importance. One way
