Abstract

With the onset of the World Wide Web, authors of digital media (i.e. an image, song, video) can easily distribute their works by making them available on Web pages or other public forums. Anyone having access to those forums can copy the author’s media. By the nature of digital media, a copy is an exact, perfect duplicate of the original. This brings to front a potential problem about how do authors claim ownership rights of such digital media when multiple persons have exact copies. Digital watermarking aims to hide secret information in digital multimedia contents. The secret information is embedded in the contents itself by actively modifying contents, but in such a way that it causes only slight and imperceptible modification. It is a technique which embeds the less amount of data, but requires the greatest robustness. The embedded information, which is known as a watermark, can provide, for example, information about the media, the author, copyright, or license information.
