摘要:
A right management server manages usage of a content on a parent terminal and a child terminal. The right management server includes content usage right database that stores right information indicating a usage rule of a content for each terminal ID or user ID, and a parental control information management unit that acquires, from the parent terminal or the parent user, parental control information that is an instruction to put a restriction on usage of a content on the child terminal or by a child user, and stores the parental control information in a parental control information database. The right management server also includes a license ticket generation unit that acquires a license ticket issuance request from the child terminal or the child user, generates a license ticket that is information for permitting usage of the content on the child terminal or by the child user, under a usage rule with a restriction indicated by the parental control information which is held in the parental control information management unit, and sends the license ticket to the child terminal or the child user.

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:
The present invention provides a mutual rating system in which objects, such as users, content, and terminal devices, on the network can be rated and ratings for the objects can be checked without using a server. In the rating system, objects (users, content, terminal devices, etc.) associated with a network (3) are rated. The mutual rating system is connected to the network (3), and includes: a plurality of third party terminals (1(#3)) having stored therein rating information related to objects previously rated by the user; and content demanding terminal devices (1(#1)) for collecting rating information related to desired objects from all online rating information stoning terminal devices. Each content demanding terminal device (I(# I )) analyzes rating information collected from the third party terminal devices (1(#3)) to obtain a rating for a desired object.

The invention relates to power saving in portable terminals (100) with recording media (200). Conventionally, there is the problem that a battery (104) in the portable terminal (100) may become exhausted and as a result the original function of the terminal cannot be performed. To solve this problem, when the remaining battery capacity is low, the invention controls power supply (108) to the recording media (200) and clock supply (110) to a CPU (202) in the recording media (200) so as to reduce power supplied to the recording media (200)

A network connection device includes: one or more network devices; a network switching control section configured to determine a second network as a candidate network to which connection is subsequently switched from a first network to which a network device is currently connecting; a network relation state determination section configured to determine whether or not the network device is used for forming a PAN; a disconnection-caused disadvantage determination section configured to determine whether or not a disadvantage to a user will be caused by switching connection to the second network, based on the result of the determination by the network relation state determination section; and a switching acceptability determination section configured to prohibit switching connection to the second network when the result of the determination is that a disadvantage to the user will be caused.
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:
A content playback apparatus reduces load concentration on a specific server apparatus that manages content keys of encrypted content, while protecting copyrights of the content. The content apparatus makes playback of content recorded in a recording medium sold possible after the specific server breaks down. A key acquisition control unit (204) reads a playback control information table (211) from a recording medium (102) via a reading unit (201). The key acquisition unit (204) acquires a rights key via a key acquisition intermediation unit (223) from an apparatus specified by an acquisition-destination type and a request-destination type that are stored in the playback control information table (211) and that corresponding to the content to be played. The key acquisition unit (204) generates a content key using the acquired rights key and, when required, a medium key recorded in a medium. A decryption unit (203) decrypts encrypted content using the content key.
