Abstract
Watermarking techniques have been proved as a good method to protect intellectual copyrights in digital formats. But the simplicity for processing information supplied by digital platforms also offers many chances for eliminating marks embedded in the data due to the wide variety of techniques to modify information in digital formats. This paper analyzes a selection of the most interesting methods for image watermarking in order to test its qualities. The comparison of these watermarking techniques has shown new interesting lines of work. Some changes and extensions to these methods are proposed to increase its robustness against some usual attacks and specific watermark attacks. This works has been realized in order to provide the HYPERMEDIA project with an efficient tool for protecting IPR. The objective of this project is to establish an experimental stage on continuous multimedia material (audiovisuals) handling and delivering in a multimedia service environment, allowing the user to navigate in the hyperspace through database which belong to actors of the service chain and protecting IPR of authors or owners.
