发明名称 Method and apparatus for legitimate sharing of electronic content
摘要 A method of distributing electronic content including metadata for that content comprises the following: reading the metadata to identify the content; identifying a holder of the copy; determining if the metadata includes licence data and whether the holder of the copy is a licensee; and, if not, receiving payment for that copy of said content so that said holder becomes an owner or licensee of said content. New licence data is then provided for inclusion in the metadata of that copy of the content to identify the holder as a licensee of said content.
