Effects of Fragile and Semi-fragile Watermarking on Iris Recognition System

2015
Security is an important issue in biometric recognition systems. In recent years, many researchers proposed to use watermarking to improve the security of biometric systems, but some people concern whether the embedded watermarks will influence recognition results.

Fractal Based Fragile Watermark

2009 Second International Conference on Computer and Electrical Engineering, 2009
The protection of ownership and the protection of unauthorized tampering of multimedia data (audio, image, video, and document) have become a major concern for the authors of multimedia. Image authentication verifies the originality of an image by detecting malicious manipulation The protection of ownership and the protection of unauthorized tampering ...

Distortion-free fragile watermark for relational databases

International Journal of Big Data Intelligence, 2016
Unauthorised changes to databases may result in significant losses for organisations. Digital watermarking can be used for protecting the integrity of relational databases. Prior techniques introduce distortions to the watermarked attributes and thus limit their application.

Fragile watermarking schemes for image authentication: a survey

International Journal of Machine Learning and Cybernetics, 2017
This paper presents a survey of fragile watermarking schemes for image authentication proposed in the past decade. The limited embedding capacity and extent of tampering are some of the important issues among other issues that drive the research in this area.

Image authentication by means of fragile CGH watermarking

SPIE Proceedings, 2005
In this paper we propose a fragile marking system based on Computer Generated Hologram coding techniques, which is able to detect malicious tampering while tolerating some incidental distortions. A fragile watermark is a mark that is readily altered or destroyed when the host image is modified through a linear or nonlinear transformation.

Fragile Watermarking Scheme for Accepting Image Compression

2005
As images are commonly transmitted or stored in compressed form such as JPEG lossy compression, image authentication demands techniques that can distinguish incidental modifications (e.g., compression) from malicious ones. In this paper, we propose an effective technique for image authentication which can prevent malicious manipulations but allow JPEG ...
