摘要： A management apparatus reduces the number of pieces of unique information each not generated from another piece of unique information, among unique information being bases of keys assigned to managed apparatuses.The management apparatus calculates, for nodes in layers other than tree structure leaves, subsets of apparatus identifiers subordinate to the nodes, searches for a subset wholly containing another subset in the lowermost layer other than a leaf layer from an immediately-upper layer and mutually associates these subsets, searches for another subset wholly containing the containing subset from a same or an immediately-upper layer and mutually associates these subsets, controls this processing to repeat up to the uppermost layer, controls these processings to repeat on all subsets in the lowermost layer, makes unique information correspond to subsets in the lowermost layer, and makes information derivatively obtained from the unique information correspond to subsets connected due to the associating.

摘要： A content protection system prevents illegal key acquisition, without checking uniqueness of device keys. The content protection system includes a key data generation apparatus and a user terminal. The key data generation apparatus converts first key data, which is for using content, based on a predetermined conversion rule, thereby generating second key data, encrypts the second key data using a device key held by valid terminals, and outputs the encrypted key data. The user terminal obtains the encrypted key data, decrypts the encrypted key data using a device key held by the user terminal, thereby generating second key data, converts the second key data based on a re-conversion rule corresponding to the conversion rule, thereby generating the first key data, and uses the content with use of the generated first key data.
摘要翻译：内容保护系统防止非法密钥获取，而不会检查设备密钥的唯一性。内容保护系统包括密钥数据生成装置和用户终端。密钥数据生成装置基于预定的转换规则，对使用内容的第一密钥数据进行转换，从而生成第二密钥数据，使用由有效终端保持的装置密钥对第二密钥数据进行加密，并输出加密的密钥数据。用户终端获取加密的密钥数据，使用由用户终端保存的设备密钥解密加密的密钥数据，从而生成第二密钥数据，并根据与转换规则对应的重新转换规则转换第二密钥数据，从而生成第一密钥数据，并使用所生成的第一密钥数据的内容。

摘要： A content of Copy Once cannot be copied to an external device or the like, even for the purpose of making a backup. This is inconvenient for the user. However, if copying to another device for the purpose of making a backup is permitted, the content may be copied in an unauthorized manner. The present invention provides the hard disk recorder that transmits the content to the backup device, sets an expiration time in the content stored in the hard disk recorder itself, and deletes the content stored in the hard disk recorder itself after the expiration time expires.

摘要： A theft prevention system capable of preventing theft of a target object by disabling the authorized key of the target object in the case where the authorized key has been stolen. When the authorized key is lost, a mobile telephone instructs a vehicle control device to set a warning mode. On receipt of this warning mode instruction, the vehicle control device sets warning mode, generates an electronic key, and transmits the generated electronic key to the mobile telephone, which receives and stores the electronic key. Once the warning mode is set in the vehicle, locking and unlocking are only possible using the electronic key. If the authorized key is found, the mobile telephone instructs the vehicle control device to set the normal mode. Upon receipt of this normal mode instruction, the vehicle control device sets the normal mode in the vehicle.

摘要： To provide a backup management device that deletes a content so as to be restorable in the future while protecting a copyright of the content, in a case where there exists a backup of the content. In an HD recorder, a first information storage unit stores a content, a second information storage unit stores a backup of the content, a secure storage unit stores a hash value of the content. If receiving an instruction to delete the content so as to be restorable, a control unit deletes the content from the first information storage unit. When the content is played back, an encryption processing unit applies a calculation to the content to generate detection information, and the control unit compares the hash value with the detection information to judge whether the content has been tampered.

摘要： Disclosed is a group admission system having a client and a server that belongs to a closed group within which contents are available. The client determines whether it is permissible to request to join the group to be a member device thereof based on the number of groups that the client is in and the maximum number of groups that the client is permitted to be in. If permissible, the client transmits a registration request to the server with information unique to the client. The server determines whether to permit the client to join the group by registering with the server based on the number of member devices registered with the server and the maximum number of member devices registerable with the server. If it is permitted, the server registers the unique information, and transmits group identification information to the client. The client receives and stores the group identification information.

摘要： The recorder/reproducer, when moving a first content data, writes a second content data, which is obtained by re-coding the first content data recorded in a first recording medium, into a second recording medium instead of the first content data, writes one or more first partial information extracted from the first content data into the second recording medium, and makes the first content data irreproducible, using one or more first invalidated partial information having one-to-one correspondence with the extracted one or more first partial information. When restoring the first content data, it makes the irreproducible first content data reproducible, using the one or more first partial information recorded in the second recording medium.
