'Image authentication using hierarchical semi-fragile watermarks' published in 'e-Business and Telecommunication Networks'

Abstract: In this paper, a semi-fragile watermarking technique operating in the wavelet domain is proposed. A hierarchy of the image blocks is constructed ...

The aim of this paper is to present a review on different Machine learning techniques as Fuzzy Set theory, Rough Set Theory, Rough K-means clustering, ...

In this paper, a semi-fragile watermarking technique operating in the wavelet domain is proposed. A hierarchy of the image blocks is constructed and the image ...

We proposed a method that generates a set of semi-fragile samples for a model to achieve the content authentication and tampering localization.

In this paper, we present a new localized hierarchical method of watermarking for semi-fragile watermarks used in content authentication of images.

A hierarchical semi-fragile digital watermarking algorithm was designed for image content integrality authentication, tamper localization and recovery. In ...

The proposed technique is capable of detecting and localizing malicious attacks as well as colour tampering. Experimental results are presented to demonstrate ...

Generally, the fragile watermark used for image authentication can be divided into two types including semi-fragile watermark and complete fragile watermark ( ...

Using a hierarchical structure, we propose a method that thwarts the VQ attack while sustaining the superior localization properties of blockwise independent ...
