    • A function managing apparatus allows a user to avoid a fault likely to occur in a user terminal before a new function is installed on the user terminal. A function managing apparatus for communicating with a user terminal is provided. Specifically, the function managing apparatus includes a receiving unit, predicting unit, and alerting unit. The receiving unit receives from the user terminal the new function ID identifying the new function to be installed on the user terminal, and the installed function IDs identifying one or more functions previously installed on the user terminal. The predicting unit specifies the new function and one or more installed functions based on the new function ID and installed function IDs received by the receiving unit, and predicts the result when the new function is installed on the user terminal. The alerting unit notifies the user terminal of the prediction result of the predicting unit.
    • 功能管理装置允许用户在用户终端上安装新功能之前避免在用户终端中可能发生的故障。 提供了一种与用户终端进行通信的功能管理装置。 具体地,功能管理装置包括接收单元,预测单元和警报单元。 接收单元从用户终端接收标识要安装在用户终端上的新功能的新功能ID,以及识别用户终端上预先安装的一个或多个功能的已安装功能ID。 预测单元基于由接收单元接收到的新功能ID和安装的功能ID来指定新功能和一个或多个安装的功能,并且当将新功能安装在用户终端上时预测结果。 报警单元向用户终端通知预测单元的预测结果。

    • A memory card 13 includes wireless network communication unit for having electronic equipment to access a storage server 11 on a network. The storage server 11 includes at least a non-authentication area 111. Data such as contents is written into a non-authentication area of the memory card 13 or the non-authentication area 111 of the storage server 11. In other words, an area of a storage area to which data can be written is expanded by the non-authentication area 111 of the storage server 11. Thus, the non-authentication area of the memory card 13 increases apparently. Encoding key used for encoding and decoding contents protected by copyrights is written to an authentication area on the memory card 13. Anyone can access content data in the non-authentication area 111 of the storage server 11, but an encoding key required for decoding the content is in the memory card 13. Thus, only a person who has the memory card 13 and valid electronic equipment can decode, reproduce and output the content using the encoding key. In this way, the storage capacity of the memory card 13 can be increased apparently while security of data protected by copyrights is guaranteed.
    • 存储卡13包括用于使电子设备访问网络上的存储服务器11的无线网络通信单元。 存储服务器11至少包括非验证区域111。 诸如内容的数据被写入存储卡13的非验证区域或存储服务器11的非验证区域111。 换句话说,可以通过存储服务器11的非认证区域111扩展可以写入数据的存储区域的区域。 因此,存储卡13的非验证区域明显增加。 用于编码和解码受版权保护的内容的编码密钥被写入存储卡13上的认证区域。 任何人都可以访问存储服务器11的非验证区域111中的内容数据,但是将内容解码所需的编码密钥存储在存储卡13中。 因此,只有具有存储卡13和有效电子设备的人才能使用编码密钥对内容进行解码,再现和输出。 以这种方式,存储卡13的存储容量可以明显地增加,同时保护受版权保护的数据的安全性。

    • A network device restricts functions thereof in a special case such as theft, and comprises: an acquisition unit for acquiring one or more identification information pieces corresponding to one or more local devices in a communicable state; a calculation unit for calculating an index value for each local device; a holding unit for holding, for each local device whose identification information piece was acquired in the past, the identification information piece of the local device and the index value thereof; a difference specifying unit for specifying a difference between (i) one or more identification information pieces currently acquired and (ii) the one or more identification information pieces acquired in the past, thereby specifying a local device as the difference; and a judgment unit for judging whether to restrict the access based on the index value of the local device specified as the difference.
    • 网络设备在特殊情况下限制其功能,例如盗窃,并且包括:获取单元,用于获取与可通信状态中的一个或多个本地设备相对应的一个或多个识别信息; 计算单元,用于计算每个本地设备的索引值; 保持单元,用于对于过去获取了识别信息的每个本地设备,保存本地设备的识别信息片及其索引值; 差分指定单元,用于指定(i)当前获取的一个或多个识别信息段与(ii)过去获取的一个或多个识别信息之间的差异,从而指定本地设备作为差异; 以及判断单元,用于基于指定为该差异的本地设备的索引值来判断是否限制访问。
