Fragile watermarking scheme for image authentication

Electronics Letters, 2003
A simple fragile watermarking scheme for image authentication is proposed. The insertion of a binary watermark is accomplished by replacing the least significant bit of the host image with a random binary image obtained by random permutations and suitable XOR operations among bitplanes.

Multibranch Collaboration and Segmented Training Network for Image Forgery Comprehensive Detection

IET Biometrics, Volume 2026, Issue 1, 2026.
With the rise of sophisticated image manipulation techniques, image detection forgeries have become increasingly challenging. This paper presents a novel deep learning framework, the multibranch collaboration and segmented training network (MBC‐STN), for robust image forgery detection. MBC‐STN addresses the challenges posed by diverse forgery types and

Synthesis of Programmable Bioelectronic Yeast for Biohybrid Futures

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 ...

Influence of Nano Titanium Dioxide Coating on the Dust Accumulation Behavior of Polymethyl Methacrylate

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Polymethyl methacrylate (PMMA) has the advantages of excellent transmittance, light weight, high impact strength, good weather resistance, etc. and can be used as a substitute of glass in solar energy utilization technology. Difference in the roughness of materials can lead to the difference in the adhesion of dust to their surfaces. In this paper, 194

A Quantitative Descriptor for Chalky and Discoloration Damage in Rice Grains

Journal of Food Quality, Volume 2026, Issue 1, 2026.
The quality assessment of chalky and discolored rice grains is often limited to either subjective methods or single‐value metrics that fail to capture the finer details of these damages. Despite being detectable and rich in visual features, there is a lack of a quantitative framework for characterizing these damages within a single rice grain in terms ...

Multianalytical Study of Amuletic and Talismanic Islamic‐African Paper Manuscripts in the Slovene Ethnographic Museum

ChemPlusChem, Volume 90, Issue 12, December 10, 2025.
The image illustrates a multi‐technique analysis of Islamic‐African manuscripts from the nineteenth to twentieth centuries. It highlights methods like microscopy, hyperspectral imaging, FTIR, LIF, Raman, LIBS, and furnish analysis used to study paper fibers, inks, and dyes—revealing a blend of local and trade materials and a rich fusion of Qur’anic and
