Abstract
A service provider (SP) receives an original license including an edit condition that shows designation of a range of a usage condition from a content provider (CP) license management server of a CP. On the basis of the received original license, a sales license generation tool of the SP generates a sales license which includes the usage condition that shows a condition for allowing the usage of the content and from which a content key has been deleted. A content key insertion processing unit of an SP license management server judges whether or not the usage condition included in the generated license information is within the range of the edit condition, and inserts the content key into the generated license information only when the usage condition is within the range of the edit condition.
