摘要: The invention provides a method of forensic digital watermarking (102) that randomly selects an orientation and/or embedding protocol for watermark signal to be embedded in the content (100). It then embeds at selected applies different each instance watermark. This thwarts averaging and over-embedding attacks enables generational tracking.
