| 1. A multi-source system that includes a plurality of sources, comprising:
at least one point of origin that generates, in response to digital content, watermarked digital content having a set of locations
therein at which fingerprinting information can be embedded;
at least one intermediate device disposed between said point of origin and an end viewer, wherein said device partially fingerprints
said digital content when sending information for presentation to said end viewer, whereby said partially-fingerprinted digital
content is generated at each said intermediate device and includes information sufficient to identify that intermediate device
and a recipient of that partially-fingerprinted digital content from that intermediate device.
