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： 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=GˆXinv mod q, and a second characteristic parameter KBi=Xi. The information providing device generates a semi-anonymous individual identifier C=(KAi)ˆD mod P. The anonymity server device calculates an anonymous individual identifier E=(C)ˆKBi mod P.
