摘要： A reservation changing system provides diverse services. A memory card 200 obtains, via a mobile telephone 400, a distance from a present location to a boarding station for a train for which a reservation has been made, and judges whether to perform a train reservation change search depending on the relationship between the obtained distance and a time remaining until a departure time of the train. When it is judged that a reservation change search is to be performed, the memory card 200 obtains an expected arrival time at the station from a timetable server apparatus 500, compares the obtained expected arrival time with the departure time, and when a time margin between the two times is insufficient, the memory card 200 instructs a reservation center apparatus 300, via the mobile telephone 400, to change the reservation, and receives and stores reservation information.
摘要翻译：预订系统提供多种服务。存储卡200经由移动电话400从已经进行了预约的列车获得从当前位置到登机站的距离，并且根据所获取的关系来判断是否进行列车预约变更搜索距离和直到火车出发时间剩余的时间。当判断为要执行预约变更搜索时，存储卡200从时刻表服务器装置500获得在该站处的期望到达时间，将获得的预期到达时间与出发时间进行比较，两次不足，存储卡200经由移动电话400指示预约中心装置300改变预约，并且接收并存储预约信息。

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 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： A recording and reproduction apparatus for preventing illegitimate use of contents. A recording medium stores an inherent number in an unrewritable area. The recording apparatus writes media key data and an encrypted content onto the recording medium. The media key data includes encrypted media keys generated by (i) for each of unrevoked reproduction apparatuses, encrypting a media key using a device key of the unrevoked reproduction apparatus respectively, and (ii) for each of revoked reproduction apparatuses, encrypting detection information using a device key of the revoked reproduction apparatus. The reproduction apparatus decrypts the encrypted media key using a device key to generate a decryption media key, judges whether the decryption media key is the detection information, and prohibits the encrypted content recorded on the recording medium from being decrypted when judged in the affirmative.

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.
