| titleOfInvention | Resolution-independent watermark detection |
| abstract | The present invention provides a method for performing watermark detection on a signal x comprising a sequence of samples, the samples having a word length L. A method according to the invention comprises determining whether a subsequence xs of x fulfils a watermark attack suspicion criterion corresponding to a specific watermark attack, and in an affirmative applying a counter-algorithm to a part of the signal to produce a detection sequence, and applying a watermark detection algorithm to the detection sequence to determine whether a watermark is present in the signal or not. The invention is applicable for instance in relation to watermarked audio signals or video signals. |
