发明名称 System and methods for managing the distribution of electronic content
摘要 The present invention provides systems and methods for transfering electronic information from one location to another such that only one original work exists at a given time. The methods and systems of the present invention allow distribution of originals without requiring a registration authority or other entity to vouch for what constitutes an "original" piece of information, thus reducing (or eliminating entirely) the need to centrally record changes in ownership each time originals change hands.
