    • In a data utilizing system, a statistic table exhibiting a characteristic distribution is automatically extracted from given statistic tables of data. After confirmation of distribution of the data on the extracted statistic table, data required is retrieved from the statistic table. The data utilizing system for extracting from data constituted by a set of records each composed of at least two item values each containing at least one numeric item value, a part of the records constituting a part of the data, includes: as statistic table list generating unit for generating from the data statistic tables of component data for which at least one item value is definitely specified, and for determining arithmetically characteristic quantities for the statistic tables, respectively, on the basis of differences between the statistic tables and relevant expected value distribution tables, to thereby generate a list of the statistic tables on the basis of the characteristic quantities; and a record list generating unit for generating from the data a list of records contained in all or at least one specified cell of a specified given one of the statistic tables.
    • 在数据利用系统中,从给定的数据统计表中自动提取展示特征分布的统计表。 在提取的统计表上确认数据分发后,从统计表中检索所需的数据。 数据利用系统,用于从由至少两个项目值构成的数据组成的数据中提取数据,所述至少两个项目值包含至少一个数值项,所述记录构成数据的一部分的部分包括:作为统计表表生成 单元,用于根据明确指定至少一个项目值的组件数据的数据统计表生成,并且用于基于统计表和相关期望值分布表之间的差异来分别确定统计表的算术特征量 从而基于特征量生成统计表的列表; 以及记录列表生成单元,用于从所述数据生成包含在指定给定统计表中的所有或至少一个指定单元格中的记录列表。

    • In the conventional technique for mainly performing access control, an entity (an individual) which provides information cannot grasp a state of use of personal information. In the conventional technique for encrypting stored data, a decryption key is always required when personal data is used and the personal data is not protected once decrypted. The invention constitute a system such that a purchase history is collected according to an anonymous ID and a response from a member card or an agent server is required for operation for associating the anonymous ID with a personal ID. Personal data itself is not encrypted but stored in a plain text with the personal ID and the anonymous ID as keys such that the anonymous ID is regenerated every time the anonymous ID is associated with the personal ID on a server side. At this point, the anonymous ID serving as a collection key for the purchase history, which is accumulated concurrently, is also regenerated.
    • 在主要执行访问控制的传统技术中,提供信息的实体(个人)不能掌握个人信息的使用状态。 在用于加密存储的数据的常规技术中,当使用个人数据并且一旦解密就不保护个人数据时,总是需要解密密钥。 本发明构成了一种系统,使得根据匿名ID收集购买历史,并且需要来自会员卡或代理服务器的响应用于将匿名ID与个人ID相关联的操作。 个人数据本身不被加密,而是以个人ID和匿名ID作为密钥存储在纯文本中,以便每当匿名ID与服务器端的个人ID相关联时,重新生成匿名ID。 此时,还重新生成作为同时累积的购买历史的收集密钥的匿名ID。
