Distortion-Free Secret Image Sharing Mechanism Using Modulus Operator
, 2009 [[abstract]]The (t, n)-threshold has been extended to secret image sharing due to its practicability. In this article, we provide a novel version that employs the modulus operator to embed the secret share into a host image.

Ecography, EarlyView.Occurrence records are fundamental for ecological and evolutionary research, providing key information on species' geographic ranges. However, these records are often taxonomically, spatially, and temporally biased, requiring caution in their use. Here, we analysed the spatial coverage of occurrence records for over 3500 snake species worldwide to ...

Environmental Policy and Governance, EarlyView.ABSTRACT Freshwater availability is a critical climate change challenge in coastal delta regions. This challenge requires a transformative change toward circular water management. While experimentation and collaborative governance are recognized as enablers of transformative change, their interaction remains complex and insufficiently understood ...

A self-authentication mechanism for a (3,3)-threshold secret sharing scheme
, 2012 [[abstract]]Secret sharing is widely used in secret image protection since 1979. Image secret sharing schemes are used to encrypt the secret image into several meaningless share images. Later on, the secret image can be reconstructed while collecting the

Two-Layered Structure for Optimally Essential Secret Image Sharing Scheme
, 2017 This paper presents a two-layered structure for optimally sharing a secret image among s essential and n − s non-essential shared shadows using the (t, s, k, n) essential thresholds, that t essential shared shadows and totally k shared shadows are needed

Energy Science &Engineering, EarlyView.Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Secret Image Sharing Based on Discrete Cosine Transform
, 2014 The main challenges facing secure image sharing tasks are the increase of sharing volume and sharing-control flexibility. A new scheme based on DCT is developed to perform packet secret image sharing, the DCT is used to reduce the secret image size ...

Keeping their powder dry: Purity, pollution, and handgun ownership among Jewish women in Israel
Feminist Anthropology, EarlyView.Abstract This article examines the gendered practices through which Jewish women in Israel experience and negotiate personal handgun ownership in everyday life. Drawing on interviews, participant observation in gun‐related spaces, and analysis of women‐only online forums, we explore the expanding participation of Jewish women in civilian gun ownership,
