    Abstract: Methods for adapting the operation of a system in response to the detection of embedded watermarks from a digital host content are provided. A digital host content is received and examined for the presence of watermarks. In response to the detection of embedded watermarks and in accordance with the value, type, density or spacing of the detected watermarks, one or more system reactions may take place. These reactions include conditionally allowing the system to resume its normal operation, prohibiting the system from resuming its normal operation, degrading the quality of the digital host content or changing the security status of the digital host content. In response to the extraction of weak watermarks that do not meet the desired system requirements, the extraction operation may be modified or extended to enable the detection of strong watermarks.

    Abstract: A system for creating non-repudiation (undeniable) watermarks, wherein a content provider uses outside distribution entities to distribute media content supplied by the content provider. Content watermarked by a distribution entity using this system is undeniably recognizable by the content provider as originating with that particular distribution entity. In other words, given N distribution entities, the content provider is able to tell which particular distribution entity watermarked the media content. The system does not allow any distribution entity to watermark media content so that would appear to have been watermarked by another distribution entity and the system does also not allow the content provider to watermark media content so that would appear to have been watermarked by a particular distribution entity. Consequently, this allows the content provider to place a high degree of trust in the identification of the distribution entity by means of the watermark.
