I know a company that does this for broadcast media and one of the main uses is for big media production houses like Paramount, Universal, Warner Bros to watermark screening copies of DVDs submitted for festival juries such that if it gets leaked, they are able to trace it back to the exact person it originated from. 

The company is called Civolution http://www.civolution.com/home/

In short I know the technology is available for audio and video assets (http://www.civolution.com/technology/digital-audio-and-video-watermarking/) but I don't think digital fingerprinting or watermarking is available for text files, if that's what you mean Doc?

Is there yet a way yet to watermark shared data, or to concatenate information about who is sharing it with whom — so if the data arrives at D, it carries evidence it was shared by A with B, who then shared it with C, who then shared it with D.
