Universities, Governmental administrations, photography agencies and many other companies or individuals need framework to manage their multimedia documents and the copyright or authenticity attached to their images. We purpose a web-based interface able to realize many operations: storage, image navigation, copyright insertion, authenticity verification. When a photography owner wants to store and to publish the document on the Internet, he will use the interface to add his images and set the internet sharing rules. The user can choose for example watermarking method or resolution viewing. He set the parameters visually in way to consider the best ratio between quality and protection. We propose too an authenticity module which will allow online verification of documents. Any user on internet, knowing the key encoding, will be able to verify if an watermarked image have been altered or not. Finally, we will give some practical examples of our system. In this study, we merge the last technology in image protection and navigation to offer a complete scheme able to manage the images published. It allows to use only one system to supply the security and the publication of their images.
