摘要：
A method of embedding a watermarking in a host signal computes a first watermark depending on a particular party and computes a second watermark depending on the host signal. The method embeds the first and second watermarks in the host signal. At least one of the watermarks is embedded using a key derived from the host signal. In particular, one of the watermarks is embedded with a key derived from the host signal.
