    • An object of the present invention is to, in settlement by electronic money, reduce burden on an electronic money server and enhance convenience for users. The function of generating transaction numbers is transferred from the electronic money server to affiliated store servers, so that the transaction numbers are generated by the affiliated store servers. The transaction numbers are each associated with transaction information calculated in accordance with a calculation rule confidential to third parties, such that the electronic money server can detect the presence of alteration of the transaction information based on the transaction number. Furthermore, at the time of generating a transaction number, a seed, which is time-limited secret information confidential to third parties, is inputted to the calculation rule along with the transaction information and used for calculating the transaction number, whereby it is possible to further enhance the level of security.
    • 本发明的目的在于,通过电子货币进行结算,减轻了电子货币服务器的负担,增加了用户的便利性。 生成交易号码的功能从电子货币服务器传送到附属店铺服务器,以便交易号码由附属店铺服务器生成。 交易号码各自与根据对第三方机密的计算规则计算的交易信息相关联,使得电子货币服务器可以基于交易号码来检测交易信息的改变的存在。 此外,在生成交易号码时,将对第三方机密的时间有限的秘密信息的种子与交易信息一起输入到计算规则,并用于计算交易号码,由此可以 进一步提升安全水平。

    • A multi-master node model database management technology involves notifying a higher-level master node of a transaction minimum value as a minimum value of an implementation-underway transaction in a snapshot from a lower-level master node, comparing the transaction minimum value with minimum values retained by the respective master nodes and thus updating a node minimum value and a cluster minimum value. Then, the lower-level master node transmits a write set containing a shadow copy of its own database, a heap tuple map deployed on its own memory and the transaction minimum value to the higher-level master node, and the higher-level master node receiving the write set updates the database by use of the write set if the transaction minimum value is equal to or larger than the cluster minimum value, and aborts the write set if the transaction minimum value is smaller than the cluster minimum value.
    • 多主节点模型数据库管理技术涉及将较高级别的主节点通知较低层主节点的事务最小值作为快照中实施执行事务的最小值,将事务最小值与最小值进行比较 由各个主节点保留的值,从而更新节点最小值和簇最小值。 然后,下级主节点发送包含其自己的数据库的卷影副本的写入集,在其自己的存储器上部署的堆组映射映射,并将事务最小值发送到上级主节点,以及上级主节点 如果事务最小值等于或大于集群最小值,则通过使用写入集合来接收写入集更新数据库,并且如果事务最小值小于集群最小值则中止写入集合。
