摘要： A CD on which only music information specified by the CD-DA is recorded, or a CD on which both music information specified by the CD-DA and music information to be recorded on a CD-ROM are recorded is mounted upon an information processing terminal (10). When the CD on which only music information specified by the CD-DA is recorded is mounted, the information processing terminal (10) acquires, from a directory server (20), an ISRC number that identifies the music information recorded on the CD, and distribution server location information that identifies a content distribution server. The information processing terminal (10) acquires content that is the music information compressed according to the MP3 and encrypted, from the content distribution server identified by the acquired distribution server location information, and the decryption key. The information processing terminal then decrypts the acquired content using the acquired decryption key and reproduces music.

摘要： In a network connecting device connectable to a network, a connection approval/disapproval determination section determines approval/disapproval of connection to a network in accordance with a connection approval/disapproval determination rule managed by a connection approval/disapproval determination rule management section. When there is a security problem in a content of the connection approval/disapproval determination rule if a connection is to be formed, the security problem is solved by having a user re-input authentication information in the content of the connection approval/disapproval determination rule.

摘要： To provide a content playback device that can use content appropriately by avoiding output of content not permitted to be used according to contract information. A playback control unit 102 extracts a content name from playback control information in a playback path information table 210, and inquires of a rights management unit 108 whether content identified by the extracted content name is playable or not. If the content is judged as being unplayable, the playback control unit 102 extracts an alternative playback number from the playback control information, and extracts a content name from playback control information whose playback number matches the alternative playback number. The playback control unit 102 then instructs a decryption unit 103 and a playback unit 107 to decrypt and play back encrypted content identified by the extracted content name.

摘要： [Object] To realize a content receiving apparatus and the like which can avoid a situation where content cannot be reproduced even when content receiving routes are switched from a broadcast wave to a communication network at an arbitrary timing. [Means to achieve the object] A receiving route switch control unit (112) determinates which receiving route is selected from the broadcast wave (20) and the communication network (30) to obtain content, and switches receiving routes based on this determination. A DRM module (140) manages the copyright of the obtained content based on a digital rights management (DRM) method defined by a provider A when content is received via the broadcast wave (20). Likewise, a DRM module (150) manages the content of copyright based on a DRM method B defined by a provider B, and a DRM module (160) manages content copyrights based on a DRM method C defined by a provider C, respectively.

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.
