On the Image Watermarking Techniques Applications, Properties and fields
Abstract
Résumé: L'expansion du world wide web et le volume sans cesse croissant de l'information digital (document, images, vidéos) mise à disposition du grand public, posent aujourd'hui un problème crucial qui n'est autre que celui du copyright .
Dans ce sens nous assistons au développement de techniques représentants tout un nouveau domaine : le Watermarking .
Cet article présente un état de l'art des techniques de watermarking ainsi q'un aperçu de domaines ou ces techniques sont applicables.
Mot clés: Watermarting/ FFT/ DCT/DWT.
On the Image Watermarking Techniques Applications, Properties and fields
Abstract:With the coming and the expansion of the World Wide Web an increased amount of digital information, such as documents, images audio and video data become available to a large number of people. Since the digital network is often used to offer digital media for profit, there is a strong need for copyright protection and a considerable interest in methods for inserting in a multimedia document a visible, or preferably invisible, mark to identify the owner. In this work, we present this new field with more details. An overview of watermarking properties, and a peer evaluation of different embedding domains is done in this work. Besides copyright protection, watermarking can serve to other applications. A survey of them and their respective requirements is also done.
Key words: Watermarking/ FFT/ DCT/ DWT.
