On the Design of Distributed Multi-User Secret Image Sharing for General Access Structures [PDF]

In this article, a secret image sharing (SIS) scheme for general access structures (GAS) is designed for distributed multi-user scenario. In the proposed distributed multi-user SIS (DM-SIS), multiple secret images are encoded into shadows which are then ...

Increasing urban flash flood risk attributable to both climate and development

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A new event impact attribution methodology that combines convection‐permitting climate model data with flood inundation modelling was used for a five‐hour flash‐flooding event in the suburbs of Leeds in 2014. The results show increased urban flood extent due to both climate change (+16%) and increased urbanisation (+29%).

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Fragmentation Across Scales, Geography, and Climate Challenges in European Urban Climate Change Adaptation and Mitigation Research: A Bibliometric and Systematic Review

Sustainable Development, EarlyView.
ABSTRACT European urban climate change research lacks integration across scales, geography, and climate challenges, despite Europe's coordinated policy frameworks. Through a hybrid bibliometric and systematic review of 1528 studies (2010–2025) using Cortext Manager and PRISMA 2020 guidelines, this study maps the conceptual patterns, knowledge gaps, and

Copyright protection for progressive image transmission with qr code and secret sharing applications [PDF]

, 2018
Progressive image transmission (PIT) can be commonly encountered in the browsers due to the bandwidth consumption of different users. With the digital nature of images, they can be easily copied and spread, and hence copyright protection of progressively

( n , n ) Multi-Secret Image Sharing Scheme with Enhanced Quality Meaningful Shares

Journal of Information Assurance and Security
Abstract Traditional visual secret sharing (VSS) schemes that encrypt secret images into noise-like images have been extended to multiple secret sharing (MSS) schemes to share multiple secret images using meaningful shares. Due to poor visual quality, such schemes are vulnerable to attacks from intruders.

How Aligned Are Citizen Preferences With the 15‐Minute Cities Paradigm? An International Survey and K‐Means Clustering Study

Sustainable Development, EarlyView.
ABSTRACT This study investigates how citizens' mobility preferences align with the principles of the 15‐Minute City (15mC), addressing three research questions: what access times and transport modes citizens consider acceptable, whether mobility preference can be clustered, and which services are perceived incompatible with the 15mC.

A Study of Secret Image Sharing Schemes [PDF]

, 2015
[[abstract]]秘密影像分享系統(Secret Image Sharing Scheme) 可以有效地解決數位資料、軍事文件及重要影像被偽造、竄改及竊取等問題。迄今, 已有許多學者建構各種秘密影像分享系統。然而, 多數皆有其缺點與限制或可改進的空間, 如: 計算過於複雜、每位參與者所持有的部分秘密(Share) 過多、只能運行於特殊的授權者集合(Access Structure)、無法同時分享多重機秘影像、無法多次使用、無法達到可驗證與偵測欺騙者的能力等問題。鑒於前述多項缺失 ...
