| 1. A system for distributing uniquely identifiable copies of a media asset comprising:
a distribution server;
a communications device coupled to said distribution server and an open network;
a data storage medium linked to said distribution server, said data storage medium comprising data representing a plurality
of unique master copies of a common presentation content having commonly partitioned segments with identifiers;
wherein said distribution server comprises programmed instructions to receive a request from said open network and send a
response to said open network through said communications device using a transmission protocol of said open network;
wherein said response comprises a distribution copy of said media asset formed by combined segments copied from different
master copies such that (a) the distribution copy contains said common presentation content, and (b) said combined segments
of the distribution copy can be uniquely distinguished from combined segments of other distribution copies by sequences of
said identifiers when a number of said other distribution copies exceeds the plurality of unique master copies.
