Secret image sharing

Computers & Graphics, 2002
Abstract In this paper, we propose a method such that a secret image is shared by n shadow images, and any r shadow images (r⩽n) of them can be used to restore the whole secret image. The size of each shadow image is smaller than the secret image in our method.

Scalable secret image sharing

Signal Processing: Image Communication, 2007
In this paper, we propose an innovative scheme, namely the scalable secret image sharing scheme, for sharing an image O among n participants such that the clarity of the reconstructed image (i.e., the amount of information therein) scales with proportion with the number of the participants.

Relations Between Secret Sharing and Secret Image Sharing

2019
Secret sharing (SS) for (k, n) threshold generates secret data into n shadows, where any k or more shadows can reconstruct the secret while any \(k-1\) or less shadows reconstruct nothing of the secret. SS is useful for cloud computing security, block chain security and so on.

Construction-Based Secret Image Sharing

2020
Most secret image sharing (SIS) schemes output noise-like shadows and are fragile to any noise due to their restoring methods are based on mathematical operations. A noise-like shadow increases the suspicion of an attacker and the fragileness leads to the secret pixel is wrongly restored even if a bit error occurs.

Computationally secure secret image sharing

2017 Iranian Conference on Electrical Engineering (ICEE), 2017
A secret image sharing scheme is used to protect the confidentiality of important images and also to safeguard them against single point of failure. the first proposed secret image sharing scheme used a technique to reduce the size of shares to 1/t of the secret, the benefits of small share size drawn the attention of many researchers to that technique

Multiple Secret Images Sharing Scheme

2008 IEEE Region 10 and the Third international Conference on Industrial and Information Systems, 2008
Secret sharing is an efficient method of transmitting the image securely. This paper discusses an efficient secret sharing scheme for multiple secret images. It has been shown through the experimental result that the proposed scheme transmits the images secretly and then efficiently recovers the same at the receiver end.

An Image Secret Sharing Method

2006 9th International Conference on Information Fusion, 2006
This paper presents an image secret sharing method which essentially incorporates two k-out-of-n secret sharing schemes: i) Shamir's secret sharing scheme and ii) matrix projection secret sharing scheme. The technique allows a secret image to be divided as n image shares so that: i) any k image shares (k ? n) can be used to reconstruct the secret image
