摘要：
This invention relates to a method and an arrangement for embedding a watermark pattern in an information signal. A method of embedding a watermark pattern in an information signal comprising the steps of determining a robust signature as a set of robust features in said information signal, creating a watermark pattern as a signature dependent function of a predefined basic watermark pattern and embedding said watermark pattern in said information signal. The invention also relates to a corresponding method and arrangement for detecting a watermark pattern in an information signal.
