    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: 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 100 instructs a vehicle control device 300a to set a warning mode. On receipt of this warning mode instruction, the vehicle control device 300a sets warning mode, generates an electronic key, and transmits the generated electronic key to the mobile telephone 100, 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 100 instructs the vehicle control device 300a to set the normal mode. Upon receipt of this normal mode instruction, the vehicle control device 300a sets the normal mode in the vehicle. Once the normal mode is set in the vehicle, locking and unlocking are only possible using the authorized key.

    摘要: A recording/playback apparatus is capable of using pre-image-converted content in a case of transferring an image-converted content to another device, then back from transfer-destination device to the recording/playback apparatus. The recording/playback apparatus includes a storage unit that stores a first encrypted content generated by encrypting the content, a second encrypted content generated by performing an irreversible compression to convert the content, thereby obtaining a converted content, and by encrypting the converted content, and a content key for decryption of the first and second encrypted contents, a key transfer unit that writes the content key to the external recording medium, and erases the content key stored in the storage unit, and a content transfer unit that, after the content key has been erased, writes the second encrypted content to the external recording medium, and erases the second encrypted content from the storage unit.

    摘要: The recorder/reproducer (101), 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.
