A Lossless Secret Image Sharing Method

2008 Eighth International Conference on Intelligent Systems Design and Applications, 2008
This paper proposes a lossless (m, n) secret sharing method based on Thien and Lin's method. First, a secret image is scrambled by the toral automorphism technique to enhance the security and then the scrambled image is shared into n shadow images by the proposed method.

Image Secret Sharing in Stego-Images with Authentication

2013
Recently, a polynomial-based (t,n) image sharing and hiding schemes with authentication was proposed to hid n shares of a secret image into n ordinary cover images and form n stego-images that can be transmitted securely. But each stego-image of all existing method should be expanded to 4 times of the secret image.

An improved scheme for secret image sharing

2010 IEEE International Conference on Multimedia and Expo, 2010
Secret image sharing is a technique used to secure digital images against disclosure and tampering. In this paper, we analyze the security of the secret image sharing scheme proposed by Thien and Lin [1] and expose its weakness. Their method uses a permutation step which requires a key.

Security Analysis of Secret Image Sharing

2017
Differently from pure data encryption, secret image sharing (SIS) mainly focuses on image protection through generating a secret image into n shadow images (shares) distributed to n associated participants. The secret image can be reconstructed by collecting sufficient shadow images.

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.

Visual Cryptography and Secret Image Sharing

2017
With rapid progress in Internet and digital imaging technology, there are more and more ways to easily create, publish, and distribute images. Considered the first book to focus on the relationship between digital imaging and privacy protection, Visual Cryptography and Secret Image Sharing is a complete introduction to novel security methods and ...

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 ...

Sharing multiple secrets in digital images

Journal of Systems and Software, 2002
The share of multiple secrets among participants in secret transmission is a critical topic for a new digital image scheme. The new scheme is derived from the least significant bit substitution method and the visual cryptography method. Given some secrets and a set of cover images, the proposed scheme will convert the secrets into many bit planes and ...

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.
