A zero‐watermarking technique based on i‐vector model for audio copyright protection

open access: yesElectronics Letters, 2023
Audio zero‐watermarking is a promising technology for audio copyright protection. It does not modify the content of the original carrier and has good imperceptibility.

Research on robust audio zero watermarking algorithm based on discrete cosine transform [PDF]

open access: yesMATEC Web of Conferences, 2020
This paper mainly uses the discrete cosine transform algorithm characteristics, combined with the “zero watermarking” embedding features, to improve the robustness of the watermark algorithm, to balance the uncoordinated relationship between robustness ...

A Coupled AquaCrop–Richards Model for Improved Crop Yield Prediction Through Physically Based Soil Water Dynamics

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Crop modelling is essential for agricultural water management but often relies on simplified water balance routines that limit representation of soil moisture dynamics. To address this limitation, we developed a coupled model that integrates the 1‐D Richards equation, solved using a finite difference method into the FAO AquaCrop.

Histogram preserving QIM-based watermarking [PDF]

open access: yes, 2012
Quantisation-based watermarking schemes are known to be strongly robust to noise and widely applied for image authentication. However, such schemes tend to create specific patterns in the histogram of the watermarked image, thus opening security gap for ...

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

open access: yesPackaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...

Identifying and Navigating Barriers to ESG Strategy Implementation: Perspectives of Corporate Senior Leaders in a MENA Context

open access: yesSustainable Development, EarlyView.
ABSTRACT Effective ESG implementation remains a critical yet persistently underachieved organisational priority, particularly in emerging markets where reporting standards, leadership capabilities, and regulatory environments remain inconsistent. This paper aims to develop an interpretive framework that senior leaders in large organisations can apply ...

Integer DCT based reversible image watermarking by adaptive coefficient modification

open access: yes, 2022
S.218-229We investigate in this paper several possible methods to improve the performance of the bit-shifting operation based reversible image watermarking algorithm in the integer DCT domain. In view of the large distortion caused by the modification of

A Fragile Zero Watermarking Scheme to Detect and Characterize Malicious Modifications in Database Relations

open access: yesThe Scientific World Journal, 2013
We put forward a fragile zero watermarking scheme to detect and characterize malicious modifications made to a database relation. Most of the existing watermarking schemes for relational databases introduce intentional errors or permanent distortions as ...

DrLS: Distortion‐Resistant Lossless Steganography via Colour Depth Interpolation

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT The lossless data steganography is to hide a certain amount of information into a container image. Previous lossless steganography methods fail to strike a balance between capacity, imperceptibility, accuracy, and robustness, commonly vulnerable to distortion on container images.

Biometric Security Through Visual Encryption for Fog Edge Computing

open access: yesIEEE Access, 2017
Fog and mobile edge computing have gained considerable attention from the research and development community. The problems related to security and privacy of biometric content are simpler to solve through edge computing resulting in improved security and
