Secret Sharing Using Meaningful Images

Journal of Advanced Management Science, 2013
In recent years, image sharing method has attracted much attention for protecting the security of secret images. Pixel expansion, meaningless sharing, and bad recovering quality are the important issues that need to be improved. The paper proposes a new image sharing method to remove the above problems.

A new Boolean-based multiple secret image sharing scheme to share different sized secret images

Journal of Information Security and Applications, 2017
The proposed Boolean-based multiple secret image sharing technique can share many secret images among participants using low computational Boolean operations. Previous studies dealt with sharing identically sized secret images; however, secret images may be of different sizes when applied to general usage.

Fast-weighted secret image sharing

Optical Engineering, 2009
Thien and Lin [Comput. and Graphics 26 (5), 765-770 (2002)] proposed a threshold scheme to share a secret image among n shadows: any t of the n shadows can recover the secret, whereas t-1 or fewer shadows cannot. However, in real life, certain managers probably play key roles to run a company and thus need special authority to recover the secret in ...

Invertible secret image sharing with steganography

Pattern Recognition Letters, 2010
The essence of invertible image sharing approaches is that the revealed content of the secret image must be lossless and the distorted stego images must be able to be reverted to the original cover image. In order to achieve these purposes, we first transform the secret pixels into the m-ary notational system and then calculate the information data ...

Nested compartment secret image sharing scheme

2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014
In the traditional secret sharing schemes, all participants are equal in terms of privileges but in special situations participants may not be equal. In this article we consider generalized compartment access structure and linear secret sharing schemes for their realization.

Secret Image Sharing with Threshold Set

Applied Mechanics and Materials, 2012
Secret image sharing is an attractive research problem in information security filed. According to the high redundancy of the digital image, the paper proposed an entirely new secret image sharing scheme with threshold set. The new scheme makes secret image sharing more flexible, so we can apply the secret image sharing technology to more fields such ...

A Robust Secret Image Sharing Scheme

2008 First International Conference on Emerging Trends in Engineering and Technology, 2008
Secret sharing is an efficient method of transmitting the image securely. This paper discusses an efficient secret sharing scheme. It has been shown through the experimental result that the proposed scheme transmits the image secretly and then efficiently recovers the same at the receiver end.

Sharing secret images using shadow codebooks

Information Sciences, 1998
Abstract A practical specific (r, n) threshold scheme for secret digital images is proposed in this paper. By this scheme, we divide a secret digital image into n pieces and distribute them to n participants. The secret digital image can be reconstructed when and only when r or more participants cooperate for it.

Parallel Processing for Secret Image Sharing

International Symposium on Parallel and Distributed Processing with Applications, 2010
Secret image sharing is a method to transmit and store an image safely. The security of secret image sharing is based on the fact that the values are operated in the finite field and the number of pixels is high enough to ensure security. However, the time complexity to encode and decode a secret image is not acceptable in real-time application.
