Distributing information, including the steps of watermarking the digital
content, distributing the digital content using a multi-source system,
and partially fingerprinting digital content at each stage of moving
information from a point of origin to the viewer. "Adaptation" of the
digital content to the recipient includes maintaining the digital content
in encrypted form at each such intermediate device, including decrypting
the digital content with a key unique to both the device and the specific
movie, selecting a portion of the watermark locations into which to embed
information, embedding fingerprinting information into those locations
sufficient to identify the recipient, and encrypting the fingerprinted
digital content with a new such key.
