Abstract: A charger control apparatus includes a total current acquisition unit and a setting unit to control a plurality of chargers connected in parallel with each other and supplied with a current from a common wiring line. An upper limit value of a current flowing through the wiring line is described as a first upper limit value. The total current acquisition unit acquires a total value of a current flowing through the plurality of chargers. The setting unit sets, for each of the plurality of chargers, a second upper limit value being an upper limit value of a current flowing through the charger by using the first upper limit value. When a difference between the total value and the first upper limit value satisfies a reference, the setting unit updates the second upper limit value for each of the plurality of chargers by distributing the difference according to a first rule.

Abstract: A block generation unit 13 generates, in a predetermined case, a block including an ID of a user in a blockchain. The block generation unit 13 generates a new block including information indicating a service provider and service contents, when face data of the user and the service contents are received from a terminal of the service provider and face authentication is successful based on the face data and face authentication data, or when the ID of the user and the service contents are received from the terminal of the service provider, and adds the new block to the blockchain.
