Abstract:
An embedder for embedding a watermark to be embedded into an input information representation comprises an information adder, which is implemented to provide the input information representation with the watermark and additional information to be added to obtain an input information representation provided with the watermark and the additional information. The additional information to be added comprises descriptive information describing the embedding of the at least one watermark into the input information representation.
