In this article we propose content based retrieval techniques as means of improving the key management used for digital watermark monitoring. In particular, we show how keys for watermark monitoring can be used on a per media item basis (rather than one secret key for all works copyrighted by a single owner), while retaining a high probability of successful spotting.
