1. An article of manufacture comprising a machine readable medium, having thereon stored instructions adapted to be executed by a processor, which instructions when executed result in a process comprising:

  • pre-analyzing a digital signal to identify potential watermarking locations within the digital signal, which potential watermarking locations are suitable for embedding one or more bits of a watermark message;

    pre-processing a watermark message to determine an exact length of the watermark message to be embedded within the digital signal based on the preanalyzing step; and

    embedding the exact length of the watermark message into the digital signal using the locations identified by the pre-analyzing step.
