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： Provided is a new system for content use and settlement. A user requests a mobile telephone charge management server (3000) to perform proxy settlement for goods purchased using mobile telephones 1 (4100), 2 (4200) and 3 (4300). The mobile telephone charge management server (3000) makes an inquiry to a registration server (3100) as to whether or not proxy settlement is possible. When proxy settlement is not possible, the mobile telephone performs settlement using electronic money that has been deposited therein.

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。
