ABSTRACT:
A method for controlling distribution of digital content includes fragmenting a digital content file into fragments and tagging at least some of the fragments with corresponding tags to provide tagged fragments for distribution. The tags may be generated using a pseudo-random number (PRN) bit sequence. A digital rights license is generated for the digital content file based on the tags and/or fragments. The digital rights license is configured to allow reassembly of the tagged fragments to provide the digital content file. Later, the fragments may be re-tagged with corresponding second tags to provide second tagged fragments for distribution that are different from the first tagged fragments. Related systems and computer program products are also discussed.
