An anonymization indicator computation system of the embodiment includes a data storing device, an anonymization device, an anonymization degree computation device, and an addition degree computation device. The data storing device stores original data including a value for each item for each person. The anonymization device generates anonymized data from the original data by anonymizing values of part of items in the original data. The anonymization degree computation device computes the anonymization degree indicating a degree of anonymizing data based on the anonymized data. The addition degree computation device computes the data addition degree indicative of a probability of generating the anonymized data from the original data.

A distributed database system accesses data by using management information managed by another data store, and accelerates a timing to update a data record having high access frequency. Thereby the latest data can be easily acquired. A distributed database system according to one embodiment comprises a distributed database including a plurality of nodes that stores data, and a data management device that manages the data stored in the plurality of nodes. Each of the nodes comprises a data storage unit that stores the data related to a time stamp representing a time when the data is stored and a key identifying the data, a data update unit that updates the data, a data sending unit acquires the data stored in the data storage unit, and a data update promotion unit that requests the data update unit to update the acquired data when the acquired data is not latest data.
