摘要： A point calculating device capable of guiding a user to a specific transportation means out of transportation means. The point calculating device collects from vehicle devices the degree of congestion of each vehicle and collects from collecting devices the degree of congestion of each train. Based on the degree of congestion of each vehicle and the degree of congestion of each train that are collected, the point calculating device calculates a train point and a vehicle point such that the lower the degree of congestion the higher the points. Further, the point calculating device receives utilization information from a portable terminal, where the utilization information is composed of a vehicle code identifying a vehicle that a user used and the date and time of the utilization. When the received utilization information is correct, the point calculating device transmits to the portable terminal a train point and a vehicle point that relate to the train and vehicle that the user used.

摘要： A recording/reproduction device (10) receives a content broadcast from a content supply device (11). The recording/reproduction device (10) encrypts the received content by using a device key and generates a first encrypted content. The recording/reproduction device (10) decrypts the first encrypted content generated, and generates a content. The recording/reproduction device (10) subjects the generated content to an image conversion so as to generate a converted content and encrypts the generated converted content by using a medium key so as to generate a second encrypted content. The recording/reproduction device (10) writes the second encrypted content, the medium key, and the device key into a portable medium (14). When the portable medium (14) is inserted into a mobile information terminal (15), the mobile information terminal (15) decrypts the second encrypted content by the medium key and reproduces it.

摘要： A recorder/reproducer (101) writes second content data produced by re-encoding first content data recorded on a first recording medium onto a second recording medium in place of the first content data when it is transferred, writes one or more first partial information extracted from the first content data onto the second recording medium, and alters the first content data into non-reproducible state using one or more first invalidated partial information corresponding one by one with the extracted one or more first partial information. The recorder/reproducer alters the first content data under non-reproducible state into reproducible state using one or more first partial information recorded on the second recording medium when recovering the first content data.

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： There is provided a value information management system capable of printing electronic data indicating value information such as an electronic receipt and preventing use of printed or unprinted electronic data for unfair billing. A secure memory card (13) securely contains an electronic receipt concerning payment. A printer (14) prints the electronic receipt and erases the electronic receipt stored in the secure memory card (13) after the printing and transmits a receipt ID identifying the printed electronic receipt to a receipt management server (17). The receipt management server (17) manages the electronic receipt identified by the received receipt ID as printed one.

摘要： There is provided a terminal device capable of using a content before conversion even if the content converted is moved to another device and the content is again moved from the device of the destination to the device of the source. The terminal device stores the content in advance, subjects the content to irreversible conversion for lowering quality so as to generate a converted content, and writes the generated converted content into the recording medium. The terminal device uses an encryption key to encrypt block 1 of the content so as to generate an encrypted block, replace the block 1 with the encrypted block, and writes the encryption key into the recording medium.
