Abstract: In a data management method, a plurality of servers store, in a distributed ledger, at least one instance of transaction data each including record information; the record information includes a record of at least one data set; and each data set includes at least one instance of data, among a plurality of instances of data generated by a plurality of devices, satisfying a condition corresponding to the data set. The data management method includes a first terminal owned by a first user of a target data set, or a second terminal owned by a second user of the target data set, performing the following: obtaining the record of at least one similar data set similar to the target data set from the record information; and determining a value of the target data set based on the record obtained.

Abstract: A control method includes obtaining, from a terminal, reservation information including use start date and time of an electric-powered vehicle that a first user hopes to use; obtaining an amount of remaining battery of the electric-powered vehicle; determining, based on the amount of remaining battery, whether an amount of remaining battery of the electric-powered vehicle is no less than a predetermined value at the use start date and time; and transmitting, to the terminal, notification information indicating a result of the determining. For example, the determination includes calculating, based on a predetermined charging characteristic unique to a battery of the electric-powered vehicle, an amount of remaining battery to be held by the electric-powered vehicle at the use start date and time upon the electric-powered vehicle being charged at a charging station; and determining whether the amount of remaining battery of the electric-powered vehicle is no less than the predetermined value.

Abstract: A control method is executed by one server out of a plurality of servers, each managing one of a plurality of distributed ledgers. The control method includes receiving first transaction data from a measured-value server over a network, the measured-value server providing, for each of one or more parameters for determining a price for a variable-price service, a measured value that corresponds to the parameter, and the first transaction data including the one or more parameters, the measured value, and a location and a time where and when the measured value is obtained; and transferring the received first transaction data to other servers different from the one server out of the plurality of servers and storing a first block including the first transaction data into a first distributed ledger managed by the one server.
