Abstract
A device 201 of a licensee γ generates an issue request for a permission to use content data by using a media identifier in a portable recording medium 101 of a licensee β, and forwards the resulting issue request to a rights management unit 71. The rights management unit 71 is managing rights information of the content data provided to the licensee β, and based on the rights information together with the issue request, generates permission information to allow the portable recording medium 101 to use the content data. Based on the permission information, the rights management unit 71 then generates license information with which the use of the content data in the device connected to the portable recording medium 101 is controlled, and transmits the license information to the device 201. The device 201 then processes the license information to control the use of the content data. In such a manner, provided is a license information management system with which the licensee β can use the content data with his or her own rights information on the device belonging to the licensee γ.
