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

Journal of Electronic Imaging, 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 images to cheat other users’ secret keys and shared images. A cheated secret key or shared image leads to

Multi-layer Secret Image Sharing

2010 Sixth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2010
Secret image sharing is a sharing method to transmit and store images with fault tolerance property. The paper proposes a recursive method to extend conventional secret image sharing more general in application which is named multi-layer secret image sharing. It enables users more controllability to secret images than conventional secret image sharing.

Multiple secret images in multiple sharing images

SPIE Proceedings, 2012
Internet based communications are evolving at a tremendous rate. Encryption of data has become an important way to protect data resources especially on the Internet, intranets and extranets. Steganography is a process of hiding data inside a sharing medium. A technique of hiding multiple images in multiple sharing images is proposed.

Secret image sharing with smaller shadow images

Pattern Recognition Letters, 2006
Secret image sharing is a technique for protecting images that involves the dispersion of the secret image into many shadow images. This endows the method with a higher tolerance against data corruption or loss than other image-protection mechanisms, such as encryption or steganography.

Exploring secret image sharing with embedding of shares

2018 2nd International Conference on Inventive Systems and Control (ICISC), 2018
Protecting the confidentiality of information has become a significant issue in information security. Secret sharing is an important technique that helps to protect the confidentiality of information. A dealer divides a secret into several shares that are distributed among a group of participants.

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.
