Method and system to digitally sign and deliver content in a geographically controlled manner via a network

摘要

A method and system to digitally sign a content license associated with content, and to distribute content via a network in a geographically controlled manner, commences when a content requestor requests delivery of the encrypted content. A content delivery system performs a content to determine a geographic location associated with the content requestor. The content requestor authorization process may also determine geographic access criteria associated with the content, and whether the geographic location complies with the geographic access criteria. The content delivery system will release the content for delivery to the content requestor if the content location complies with the geographic access criteria.
