Watermarking Integration into Portals

Abstract

Digital watermarking has become an accepted security technology to protect media such as images, audio, video, 3-D, or even text-based documents (Cox & Miller, 2002). Watermarking algorithms embed information into media data by imperceptible changes of the media. They enable copyright or integrity protection, broadcast monitoring, and various other applications. Depending on targeted application and media type, various concepts and approaches for digital watermarking exist.
