Digital rights management (DRM) and content distribution systems need to reference unique works of autorship to facilitate distribution, access control, and usage tracking and reporting of the works. The apparatus, method, and system disclosed herein is a DRM and content distribution system that uses the digital object identifier (DOI) as a unique identifier for the works of authorship that are the subject of transactions within the system and that travel with the instantiations of the works of authorship. A method of accessing a digital work from a computer is disclosed. The method associates at least one usage right with the digital work to create a protected digital work. The usage rights include displaying the digital work, copying the digital work, fowarding the digital work to another computer, or printing the digital work. The method selects a unique identifier such as a DOI for the digital work and stores the protected digital work and the unique identifier in a directory such as a library of digital works of autorship or a portion of a peer-to-peer network. The method issues a query from the computer to the directory to generate a result set that includes the unique identifier. The method uses the unique identifier to retrieve the protected digital work from the directory. Furthermore, a method is taught to employ multiple resolution capabilities for the super-distribution of DOI referenced content via E-mail and otherwise. |
