ABSTRACT:
A system for proving ownership of digital media works. Proof of ownership of such type of work is provided by a protocol for registering a work with a registration center thus providing the rightful owner or copyright holder of the work with an ownership certificate. There is also provided a protocol for proving to another party who is a prospective buyer or licensee, that an ownership claim is correct and valid by providing the ownership certificate when required. Another protocol is utilized for showing to a third party, a prospective buyer or licensee, that a second party has correctly obtained the corresponding work from the rightful copyright owner.
