Secret Image Sharing Scheme Based on a Boolean Operation

Cybernetics and Information Technologies, 2014
Traditionally extensive researches have been done on secret image sharing which support the fault tolerance property. But their reconstruction complexity is high. Some research papers on secret image sharing are also available with smaller reconstruction

A secret image sharing scheme for light images [PDF]

EURASIP Journal on Advances in Signal Processing, 2013
In this study, a new (r, n)-threshold secret image sharing scheme with low information overhead for images is provided, which has a low distortion rate, and is more applicable for light images. A secret image is encoded into n noise-like shadow images to satisfy the condition that any r of the n shares can be used to reveal the secret image, and no ...

A Novel IDO1/NE Dual Inhibitor, IMM‐H018 Prevents the Primary and Secondary Sepsis and Ameliorates the Kidney Injury Through Inhibiting the Cytokine Storm and Microthrombosis, and Reversing Immunosuppression

Advanced Science, EarlyView.
IMM‐H018, a dual IDO1/NE inhibitor, demonstrates potent therapeutic efficacy in sepsis by simultaneously targeting excessive inflammation and immune dysfunction. It prevents both primary and secondary sepsis through anti‐inflammatory, immune‐restoring, and renoprotective mechanisms, reducing organ damage, improving immune homeostasis, preserving kidney

Visual Cryptography Vs Bit Level Secret Sharing For Image Encryption [PDF]

Engineering and Technology Journal, 2010
Secret sharing is a scheme used to distribute secret among a group of users.Rather than making duplicated copies of secrets among users, the secret is dividedinto a number of pieces, called shares.

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Hierarchical Physical‐Cyber Encryption via Metasurface‐Encoded Holographic Keys

Advanced Science, EarlyView.
ABSTRACT Physical‐layer encryption based on metasurfaces has emerged as a promising alternative to conventional algorithmic cryptography by embedding security into physical processes. However, most existing metasurface‐based encryption schemes operate within single‐stage or static frameworks, where correct physical illumination directly reveals the ...

Adaptive Secret Sharing for Color Images [PDF]

International Journal of Computational Intelligence Systems, 2011
A secret sharing model can secure a secret over multiple noise-like shadows and remain recoverable despite multiple shadow failures. Even if some of the shadows are compromised, the secret will not be revealed as long as the number of the compromised shadows is smaller than a pre-determined threshold.
