Semi-Fragile Zernike Moment-Based Image Watermarking for Authentication
We propose a content-based semi-fragile watermarking algorithm for image authentication. In content-based watermarking scheme for authentication, one of the most challenging issues is to define a computable feature vector that can capture the major ...

Reversible and Fragile Watermarking for Medical Images [PDF]
A novel reversible digital watermarking technique for medical images to achieve high level of secrecy, tamper detection, and blind recovery of the original image is proposed. The technique selects some of the pixels from the host image using chaotic key for embedding a chaotically generated watermark. The rest of the pixels are converted to residues by

Evaluation of a Framework for Robust Image Reversible Watermarking
In the literature, robust reversible watermarking schemes (RWSs) allow the extraction of watermarks after the images have suffered attacks; however, the modified images are compromised.

A single watermark based scheme for both protection and authentication of identities
The security of a watermarking scheme is mainly categorised as either robust or fragile. The former can withstand an authorised alteration/attack, primarily used in copyright protection.

Digital watermarking scheme exploiting non-deterministic dependence for image authentication [PDF]
Watermarking schemes for authentication purposes are characterized by three factors: security, resolution of tamper localization, and embedding distortion.

Wavelet-based fragile watermarking scheme for image authentication [PDF]
We propose a fragile watermarking scheme in the wavelet transform domain that is sensitive to all kinds of manipulations and has the ability to localize the tampered regions.

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