Abstract :
Digital watermarking attempts to copyright the digital data that is freely available on the World Wide Web to protect the owner´s rights. As opposed to traditional, printed watermarks, digital watermarks are transparent signatures. They are integrated within digital files as noise, or random information that already exists in the file.
