摘要： A mobile communication terminal moves and backs up a content, which was downloaded from a content server, to a personal computer. When the mobile communication terminal receives an encryption key generation request from the personal computer via a cable, the mobile communication terminal extracts information to be used for generating the encryption key and generates the encryption key by using the extracted information and own telephone number. And the generated encryption key is transmitted to the personal computer via the cable. Accordingly, the backed up and moved content can be reproduced with the personal computer.

摘要： An information terminal according to this invention includes a storage means having a first storage area which is accessible from an external terminal, and a second storage area which is inaccessible from the external terminal. Content which includes a content body and rights information indicating a use condition given to the content body is acquired. The acquired content is encrypted and the encrypted content is stored in the first storage area. In addition, state management information used to manage the variable state of the use condition given to the content body is generated on the basis of the rights information included in the acquired content, and the generated state management information is stored in the second storage area.

摘要： In a first terminal serving as rights assignment source, an encoding binding state of a key encoding key included in a rights object is converted from a bind using a binding key of the first terminal and a bind using a domain key. Then, the rights object including the thus bound converted key encoding key is transferred to a second terminal serving as rights assignment destination together with encoded contents, and further, the above domain key is transferred to the second terminal via a secure session.
摘要翻译：在作为权限分配源的第一终端中，使用第一终端的绑定密钥和使用域密钥进行绑定，从包含在绑定中的权利对象中包含的密钥编码密钥的编码绑定状态被转换。然后，将包含这样约束的转换密钥编码密钥的权利对象与编码内容一起传送到作为权限分配目的地的第二终端，并且还通过安全会话将上述域密钥传送到第二终端。

摘要： A download control program of a client terminal transmits a request to a download server, which stores Download Descriptors that include attribution information of contents, for a Download Descriptor, and receives the Download Descriptor from the download server. The download server, before transmitting the Download Descriptor to the client terminal, adds information indicating that there is a difference between a Download Descriptor contained in the request from the client terminal and the Download Descriptor stored in data memory of the download server if the download server detects the difference between them. The client terminal transmits a content download request to a contents server based on the received Download Descriptor.
摘要翻译：客户机终端的下载控制程序将下载服务器的请求发送到下载服务器，下载服务器存储下载描述符，其中下载描述符包含下载描述符的内容的归属信息，并从下载服务器接收下载描述符。下载服务器在将下载描述符发送到客户机终端之前，如果下载服务器在下载服务器的数据存储器中存储有表示存在来自客户终端的请求中包含的下载描述符和下载服务器的数据存储器中的下载描述符之间的差异的信息检测它们之间的差异。客户终端基于接收到的下载描述符向内容服务器发送内容下载请求。
