An Expandable Essential Secret Image Sharing Structure

open access: yes, 2016
This study presents an expandable essential secret image sharing structure showing that some important shared images, named essential ones, are necessary when re- covering the secret image and the proposed structure must incorporate other secret image ...

Asymptotically ideal Chinese remainder theorem ‐based secret sharing schemes for multilevel and compartmented access structures

open access: yesIET Information Security, 2021
Multilevel and compartmented access structures are two important classes of access structures where participants are grouped into levels/compartments with different degrees of trust and privileges.

What drives animal responses to high severity fire? The role of functional traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

PYTHON IMPLEMENTATION OF VISUAL SECRET SHARING SCHEMES [PDF]

open access: yes
Visual secret sharing schemes (VSS) represent an important concept of visual cryptography. They permit the sharing of a secret image between multiple participants so that only authorized groups can recover the secret.

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

open access: yesBiological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Fueling Tomorrow: Scenario Planning for the Future of Gas Stations

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Transport electrification is reshaping the service infrastructures that mediate everyday mobility, yet most electrification scenario studies remain macrolevel and offer limited insight into how incumbent forecourt (gas‐station) networks can adapt under deep uncertainty.

Weighted Threshold Secret Image Sharing [PDF]

open access: yes, 2009
Given a secret image I, a threshold r, and a set of n ( ≥ r) participants P = {1, 2, ... , n} with a set of weights W = {w 1, w 2, ... , w n } where w i is the weight (which indicates the degree/rank of importance) of participant i and we assume that w 1 ≤ w 2 ≤ ... w n . The idea of weighted threshold secret image sharing encodes I into n shadows S 1,
