摘要： An application management device 54 that is capable of judging the necessity of application deletion with little load includes: a DRM application DB 520 that stores plural applications in association with their respective identification information (DRM application IDs) for identifying a correspondence between a license and an application for processing such license; and a DRM application deletion judgment unit 527 that judges, for each of the applications stored in the DRM application DB 520, whether deletion of an application is necessary or not, based on the identification information. More specifically, the application management device 54 further includes a license DB 521 for storing each license in association with the identification information, and the DRM application deletion judgment unit 527 judges that an application whose license associated with the identification information is not stored in the license DB 521, is an application to be deleted.

摘要： To reduce a frequency of recording communication management information for communication disconnection countermeasure. A digital content distribution system includes a license server (101) that issues a license, and a user terminal (103) that controls use of content based on the issued license. The license server (101) judges, according to the license to be issued, whether or not the communication management information for the communication disconnection countermeasure needs to be recorded, and notifies the user terminal of a result of the judgment. This enables the user terminal (103) to reduce the frequency of recording the communication management information.

摘要： The present invention makes it possible to use data that is held by a given terminal device in another terminal device, even after the given terminal device can no longer be accessed externally. If a terminal device 100a detects an event wherein one's own terminal will no longer be externally accessible, then the data held by one's own terminal 100a is transferred to another device 200 that can be accessed externally. Another terminal device 100b, which acquires and uses data, acquires data from the device 200, and uses such.

摘要： A broadcast station that is a transmission device assigns an ID and a license transformation period to a license to be generated, and transmits to a terminal apparatus 102, in order to provide a digital right management system which can provide a protection for the rights of a provider while preventing an unauthorized obtainment of a license to be transmitted through a digital broadcast. The terminal apparatus 102 records a license import log including the license ID and license transformation period assigned to the license. Further, the terminal apparatus 102 controls a license obtainment in the case where the same license has been obtained by the time of obtaining the license. Furthermore, the license received by the terminal apparatus 102 is kept at least until the license transformation period expires.
