SMARTMed: semi-fragile dual watermarking with deep tamper detection and adversarial DNN fingerprinting for secure medical image transmission [PDF]

Scientific Reports
Cloud-based electronic health records (EHRs) are vulnerable to modification during transmission and use, compromising security and privacy. To reduce this risk, we implemented a semi-fragile watermarking method using Slant Transform and chaotic sequences.

Synthesis of Programmable Bioelectronic Yeast for Biohybrid Futures [PDF]

Engineering Biology, Volume 10, Issue 1, January/December 2026.
This article examines how locus standardisation, genome refactoring, controlled genomic plasticity and orthogonal regulatory systems collectively establish yeast as a programmable platform. Yeast is then viewed as an analogue of electronic systems in which genetic circuits, memory and population‐level computation are compared to logic gates, storage ...

Locked down: Ontological security and the experience of COVID‐19 while living in poor‐quality housing

Journal of Community Psychology, Volume 51, Issue 6, Page 2509-2529, August 2023., 2023
Abstract The aim of the paper is to illustrate how the housing system in the United Kingdom (UK) has contributed to creating vulnerabilities during the COVID‐19 pandemic. Drawing on the concept of ontological security we look at how living with housing insecurity whilst enduring poor housing conditions has impacted the lives of those living in ...

A novel secure data outsourcing scheme based on data hiding and secret sharing for relational databases

IET Communications, Volume 17, Issue 7, Page 775-789, April 2023., 2023
Abstract Data encryption‐based and secret sharing‐based data outsourcing schemes protect the confidentiality of sensitive attributes but not their secrecy. Ciphertexts/shares generated by a data encryption/secret sharing scheme can attract the attention of interceptors. Thus, it is desired to hide the existence of highly‐sensitive attributes (as secret

Maximize the Security for Image Processing Using an Improved Watermarking Approach

Mathematical Problems in Engineering, Volume 2023, Issue 1, 2023., 2023
Creating a dependable and effective digital image watermarking (WM) method necessitates balancing imperceptibility, resilience, capacity, and security. Several studies have combined spatial and transform domains to meet these needs. We investigated the current state of hybrid digital image WM.
