摘要： Processing load on an executing device for conducting playback is high during the playback of contents since the executing device performs verification of the contents validity in parallel with the contents playback, and therefore the executing device has to be equipped with a highly efficient processor. The present invention reduces the processing load involved in the verification by using, for the verification, only a predetermined number of encrypted units selected randomly from multiple encrypted units constituting encrypted contents recorded on the DVD. In addition, the present invention is capable of improving the accuracy of detecting unauthorized contents to some extent by randomly selecting a predetermined number of encrypted units every time the verification is performed.
摘要翻译：由于执行装置与内容重放并行地执行内容有效性的验证，所以在内容的重放期间，用于进行再现的执行装置上的处理负载很高，因此执行装置必须配备高效率的处理器。本发明通过仅使用构成在DVD上记录的加密内容的多个加密单元随机选择的预定数量的加密单元来验证验证。此外，本发明能够通过每次执行验证时随机选择预定数量的加密单元，来在一定程度上提高检测未授权内容的准确性。

摘要： A data encryption apparatus reduces a hardware gate scale over that of conventional technology which uses substitution tables, and realizes high scrambling performance. The data encryption apparatus includes a data converting unit that splits 256-bit input data into 32-bit data blocks A1, B1, A2, and B2. A first combining unit (43) performs an exclusive OR operation on A1 and B1, and on A2 and B2. A first scramble unit (44) branches A1, A2, and the results of the exclusive OR operations (C1 and C2) into three data blocks each, and for each set of three data blocks, shift-rotates two of the data blocks and combines the shifted data blocks with the remaining data block. A second combining unit (45) performs an exclusive OR operation on D1 and E2, and on D2 and E1, which are the results of the processing performed by the first scramble unit (44). A block concatenating unit (46) concatenates the results of the operations performed by the second combining unit (45). A second scramble unit (47) branches the concatenated data into three data blocks, shift-rotates two of the data blocks and combines the two shifted data blocks with the remaining data block.

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： 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.

摘要： An anonymous information system is capable of maintaining anonymity of data while improving safety with regard to loss of anonymity caused by hacking of secret information, or the like. Conversion processing for converting from individual specifying information to anonymous individual information is split between an information providing device and an anonymity server device. Further, the manner in which the conversion processing is split is varied for each information providing device. A parameter generating device calculates Xinv to satisfy Xi×Xinv=1 mod q, a first characteristic parameter KAi=G^Xinv mod q, and a second characteristic parameter KBi=Xi. The information providing device generates a semi-anonymous individual identifier C=(KAi)^D mod P. The anonymity server device calculates an anonymous individual identifier E=(C)^KBi mod P.

摘要： To provide a highly user-friendly content moving device which prevents unauthorized copying of content and, when content that has been irreversibly converted and moved to a recording medium is moved back to a move source, can use the content in its form before irreversible conversion. A partial information extraction unit 110 extracts, from content stored on a content storage unit 104, partial data necessary for playback of the content, and a write/read unit 116 writes the partial data to a partial information storage unit 304 and overwrites a portion of the content corresponding to the partial data with different data, while a conversion unit 107 transcodes the content and writes the transcoded content and the partial data to the recording medium.
