摘要： In a server, an echo-request transmitting unit transmits echo-request data to a target device, and an echo-reply receiving unit receives echo-reply data from the target device. A time measuring unit measures, as the target time, the time required between transmission of the echo-request data and reception of the echo-reply data, and compares the target time with the reference time. In this way, the server judges whether the target device connected to its network belongs to a predetermined group.

摘要： A server and a client hold common secret information in respective secret information holding units. A server Cyclic Redundancy Check (CRC) unit in the server generates a CRC code after adding the secret information to communication data, and transmits the communication data with the CRC code attached. A client CRC unit of the client generates a CRC code after adding the secret information to communication data, and checks whether or not an error has occurred in the communication data on the communication path. Since the client holds the secret information, the client determines that an error has not occurred, and obtains the communication data. On the other hand, a router, which does not hold the secret information, is unable to obtain the communication data. This prevents the communication data from being transferred to devices outside an authorized domain.
摘要翻译：服务器和客户端在各个秘密信息保持单元中保存公用秘密信息。服务器中的服务器循环冗余校验（CRC）单元在将秘密信息添加到通信数据后生成CRC代码，并发送带有附加CRC码的通信数据。客户端CRC单元在将秘密信息添加到通信数据之后生成CRC码，并且检查通信路径中的通信数据中是否发生错误。由于客户端保存秘密信息，所以客户机确定没有发生错误，并获得通信数据。另一方面，不保存秘密信息的路由器不能获得通信数据。这样可以防止通信数据被传送到授权域之外的设备。

摘要： A content distribution system in which content transmission/reception is suppressed when there is a high risk of contents being stolen by a third party during communication. A content server acquires a communication distance indicating how far the content server is from a terminal in data communication. The content server conducts content transmission/reception when the communication distance is less than or equal to a predetermined value, and suppresses content transmission/reception when the communication distance exceeds the predetermined value.

摘要： A key delivery apparatus that prevents improper use of contents, and manages a decryption key for decrypting encrypted content and a suppliable number showing how many times the decryption key is suppliable, with respect to one or more terminal apparatuses connected to a network. The key delivery apparatus receives a supply request for the decryption key from a terminal apparatus, and if the terminal apparatus is a legitimate supply target, judges whether the terminal apparatus is a first-type that manages a content-usage period or a second-type that does not manage the content-usage period, and if the suppliable number has a remaining number, supplies to the terminal apparatus, the decryption key and a key-usage period of the decryption key when judged that the terminal apparatus is the first-type and the decryption key when judged that the terminal apparatus is the second-type.

摘要： A highly-convenient content duplication management system for allowing users to duplicate a content as long as the duplication is in compliance with a given usage right. In the system, a request destination device stores a content and a permitted number of duplications of the content. In response to a duplication request, the request destination device judges whether or not the request source device is an in-group device that belongs to the same group as the request destination device. When judging that the request source device is an in-group device, the request destination device transmits the content together with a permitted number that is equal to or smaller than the currently stored permitted number. The request destination device then updates the currently stored permitted number by subtracting the permitted number transmitted.

摘要： A content management system formed from a playback apparatus that requests and plays content, and a content management apparatus that manages duplication and deletion of content. The playback apparatus notifies group information of the playback apparatus to the content management apparatus, acquires information from the content management apparatus showing whether requests are permitted, and duplicates/deletes content. By judging whether the playback apparatus belongs to a group, and notifying whether a duplication request is permitted or rejected, based on in-group and out-group remaining numbers that show the remaining number of duplications permitted of apparatuses in-group and out-group, respectively, the content management apparatus relaxes restrictions on in-group content duplication as compared with out-group content duplication, and thus improves convenience for users in a home network, while protecting the rights of copyright holders, with respect to content duplication and usage.

摘要： A content management system which can prevent a content from being copied exceeding the limited number of copies for the content. The content management system includes a first content management device and a second content management device. The first content management device stores period information that indicates an available period during which a first external device is permitted to use a copied content which has been copied from the content, and outputs the period information to the second content management device when the content is moved. Upon receiving the period information from the first content management device, the second content management device judges whether the available period of the copied content has expired, using the received period information, and if it is judges that the available period has not expired, it inhibits the content from being copied to the second external device.
