摘要： A portable data sensor tag includes a memory, a data communication circuit which receives a wireless activation signal from an external terminal, and, in an operation using electromotive force generated by the received activation signal, receives an encryption key from the external terminal and stores the received encryption key in the memory. A power source supplies power, an insulator which switches a power supply from the power source from off to on, and a sensor circuit reads the encryption key from the memory, encrypts measured data using the read encryption key, and stores the encrypted measurement data in the memory. The sensor circuit operates using the power supplied from the power source after the power supply from the power source is switched on.

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： 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： 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.
