A Robust Zero-Watermarking Algorithm for Audio [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2008
In traditional watermarking algorithms, the insertion of watermark into the host signal inevitably introduces some perceptible quality degradation. Another problem is the inherent conflict between imperceptibility and robustness.

Image zero-watermarking algorithm based on region of interest

open access: yesTongxin xuebao, 2009
Based on ROI, a new watermarking algorithm was proposed.First, ROI was selected.Then, the wavelet transform was executed and ROI mask was constructed.Finally, the zero-watermarking was designed for the wavelet coefficients in ROI mask.The experimental ...

Homomorphic and Commutative Fragile Zero-watermarking Based on SVD [PDF]

open access: yesJisuanji kexue, 2022
Most of the existing watermarking and encryption schemes are difficult to ensure the commutativity of watermarking and encryption as well as the visual quality of the protected image.These schemes complete watermark embedding and image encryption ...

Multi-Instance Zero-Watermarking Algorithm for Vector Geographic Data

open access: goldISPRS International Journal of Geo-Information
To address the variability and complexity of attack types, this paper proposes a multi-instance zero-watermarking algorithm that goes beyond the conventional one-to-one watermarking approach.

Zero-Watermarking for Vector Maps Combining Spatial and Frequency Domain Based on Constrained Delaunay Triangulation Network and Discrete Fourier Transform

open access: yesEntropy, 2023
With its lossless properties, zero-watermarking has attracted a lot of attention in the field of copyright protection for vector maps. However, the common zero-watermarking algorithm puts too much emphasis on mining for global features, making it ...

Digital fragile watermarking scheme for authentication of JPEG images [PDF]

open access: yes, 2004
It is a common practice in transform-domain fragile watermarking schemes for authentication purposes to watermark some selected transform coefficients so as to minimise embedding distortion.
