A Novel Color Multi-Secret Visual Cryptography Scheme

Proceedings of the 2020 3rd International Conference on Artificial Intelligence and Pattern Recognition, 2020
In this paper a color multi-secret visual cryptography scheme specifically for (3, 4, 5) access structure is proposed with random colors and XOR operation being leveraged to generate the sharing images. The recovery images with size invariant are obtained by the XOR operation of specific combination of shares.

Verifiable Rational Multi-secret Sharing Scheme

2011
In this paper we mainly focus on the cheating problem and the incapability problem existed in rational secret sharing schemes. Based on current schemes and the related knowledge of bit commitment agreement, we proposed a verifiable rational multi-secret sharing scheme in which players can verify the identity of the dealer.

Biometric Traits in Multi-secret Digital Steganography

2017
This paper discusses the usage of biometrics in multi-secret steganography as one of three levels of information protection. Each secret is related to an individual key, which is fully or partially derived from personal trait. The chosen container is fuzzy vault cryptosystem that works well with biometric features and allows to reveal secrets ...

High-Capacity Multi-secret Sharing by Random Grid

2010 International Conference on Broadband, Wireless Computing, Communication and Applications, 2010
It’s well-known that visual secret sharing aims at encrypting a secret image into numerous meaningless sharing images by either designing a well-designed codebook or generating random bit sequence, and reconstructing the secret by superimposing them without any computation involved.

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.

A Modified Multi-Secret Sharing Visual Cryptography Scheme

2008 International Conference on Computational Intelligence and Security, 2008
A modified threshold visual cryptography scheme (k, l, n)-VCS is proposed, which is used to analyze the relationship between the pixel expansion and the range of the participants? number. Based on (k, l, n)-VCS, a more precise definition of multi-secret sharing visual cryptography scheme is given, and a new method is presented.

Fuzzy Vault Schemes in Multi-secret Digital Steganography

2015 10th International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA), 2015
This paper presents a new idea of hiding many secrets using fuzzy vault schemes. In this approach with each secret is linked corresponding key in the form of unordered set. The requirement that these sets have to satisfy is disjunctiveness. For an unauthorized user multi-secret form of fuzzy vault is identical as standard one.

Visual multi secret sharing by cylindrical random grid

Journal of Information Security and Applications, 2014
Visual secret sharing (VSS) is the process of encoding a secret image into several share images in which the original secret image can be reconstructed and recognized by stacking all of the share images together. VSS has two categories: visual cryptography (VC) and Random Grid (RG). The VC is affected by various drawbacks such as: enlarging the size of

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.

A general multi-secret visual cryptography scheme

Optics Communications, 2010
Abstract In a ( k , n ) visual cryptography scheme (VCS), a secret image is encoded into n shadow images that are distributed to n participants. Any k participants can reveal the secret image by stacking their shadow images, and less than k participants have no information about the secret image.
