PARALLEL DISTRIBUTION AND FINGERPRINTING OF DIGITAL CONTENT
First Claim
1. A method, comprising:
- receiving, at a node in a network, watermarked digital content comprising a plurality of identified locations at which fingerprinting information can be embedded, those identified locations being responsive to the digital content;
at that node, selecting a portion of those locations into which to embed fingerprinting information; and
at that node, partially fingerprinting said digital content by embedding fingerprinting information at those selected locations, whereby partially-fingerprinted digital content is generated.

Abstract
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.
