Secret sharing: using meaningful image shadows based on Gray code
Multimedia Tools and Applications, 2016Steganography, such as secret sharing, is an important technique to use for protecting transmitted confidential data from the attention of any adversaries. Gray code is a commonly encountered binary labeling that was proposed by Frank Gray of Bell Laboratories in 1940 to prevent errors when using pulse-code modulation to transmit signals.

Adaptive image sharing based on the quadri-directional search strategy with meaningful shadows
Multimedia Tools and Applications, 2016Image sharing is a technique that is used to protect the security of a secret image by placing it into shadows. In this paper, we propose a new image sharing scheme based on the quadri-directional search strategy with meaningful shadows. In the proposed scheme, a modulus reference table is generated and used to share different sizes of the secret image.

Invertible secret sharing: Using meaningful shadows based on Sorted Indexed Code
Optik, 2020Abstract The need for secret sharing using meaningful shadow images is an important method to protect the transmitted data that does not attract the attention of adversary, which has become obvious in the past few years. The recovery of the cover image without any distortion and security of the embedded secret string efficiently needs to be addressed.

Quadri-directional searching algorithm for secret image sharing using meaningful shadows
Journal of Visual Communication and Image Representation, 2015A low computational complexity for secret image sharing.High quality of generated shares.No secret information is leaked from shares, thus it guarantees high security.Satisfy four criteria: security, accuracy, computational complexity, shadow size. Contrary to conventional protecting data such as cryptographic techniques which encrypt the data with a ...

Sharing Secrets and Reversibly Reconstructing the Cover Image Using Two Meaningful Shadows
2009 Fifth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2009This paper proposes a data hiding method by secret sharing. The proposed method embeds a k-bit secret digit in a secret message (i.e., a bit stream, a secret image) into a cover pixel of a grayscale cover image at a time by generating two shadow pixels. The two shadow images produced by the proposed scheme are meaningful.

The Health Shadow Price and Economically Meaningful Threshold Values
2017In this chapter we make clear the importance of an economically meaningful threshold value reflecting opportunity costs (best alternative actions) for optimising budget-constrained societal decision making across research, reimbursement and regulatory processes.
