<P>PROBLEM TO BE SOLVED: To provide an electronic content distribution and exchange system which provides a reliable electronic content download with tracking capability and ensures secure content distribution. <P>SOLUTION: The electronic content distribution and exchange system provides authenticated, reliable content downloads and tracking capabilities. A user registers for the purchase of content through an interface on a client system or via a Web site. The purchase is for a license to the content, not for the content itself. The system provides an exchange capability similar to stock trading whereby owners offer licenses to various digital content for sale. A seller puts his license for particular content up for sale on a central server to which a buyer tenders a bid. When a price is agreed to, the central server transfers license ownership to a new owner. <P>COPYRIGHT: (C)2010,JPO&INPIT |
