A Robust Watermarking Method for Hyperspectral Images Based on Hybrid Attention Mechanism

International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.
Because of the copyright issues of hyperspectral images continue to rise, in this paper, we propose to use a neural network–based watermarking model to protect the copyright. By applying normalization‐based attention module (NAM) to deep dispersed watermarking with synchronization and fusion (DWSF), a NDWSF model is proposed for robust hyperspectral ...

Reversible watermarking scheme with image-independent embedding capacity [PDF]

Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems,

Feature-based watermarking scheme for MPEG-I/II video authentication

, 2022
S.325-335This paper presents a new content-fragile watermarking algorithm for the detection and localization of malicious manipulations of MPEG-I/II videos. While being fragile to malicious manipulations, the watermarking scheme is robust against content-

Multi-Purpose Watermarking with QR Code Applications

, 2020
: Watermarking plays an important role in the applications of copyright protection and data authentication. In this paper, we apply the commonly used discrete cosine transform (DCT), and embed two watermarks into color images.

Tamper detection, localization and self-recovery using slant transform with DNA encoding for medical images

Results in Engineering
This work proposes an improved self-embedding semi-fragile watermarking scheme for a smart healthcare system using telemedicine. The watermark is produced by encoding the Slant Transform (ST) coefficients of each block of the host image.

Security of fragile watermarking scheme for image authentication

, 2012
[[abstract]]Recently, Lu et al. proposed a fragile watermarking scheme to prevent the quantization attack. However, the present study shows that the modified scheme's objective as a fragile watermark is unfortunately lost, because it is possible for any ...

DIPS: Data Integrity Protection of Signals

Algorithms
The integrity protection of digital signals is an important task in modern applications. We propose DIPS (Data Integrity Protection of Signals), a fragile watermarking algorithm aiming to protect the integrity of sampled signals like images composed of ...
