    Abstract: Provided is a management system including vehicles and authentication servers. A vehicle includes a communication circuit, multiple electronic control units connected to an in-vehicle network, a detection circuit, and a transaction data generating circuit. The detection circuit detects a replacement of one or more electronic control units. The transaction data generating circuit generates transaction data including an identifier that uniquely identifies each of the replaced electronic control units. An authentication server includes a communication circuit, and a verifying circuit that verifies validity of the transaction data obtained by the vehicle. The authentication server also includes a recording circuit that, upon verifying that the first transaction data is valid by the verifying unit, records the transaction data in a recording device.

    Abstract: An electronic voting system including a terminal, authentication servers, and voting servers is provided. Each authentication server includes an authentication processor that authenticates a voter using authentication data including a first identifier associated with the voter and authentication information regarding the voter, and a first synchronizer that synchronizes a first blockchain including first transaction data indicating that the voter has been authenticated. Each voting server includes a voting processor that receives, from the terminal, voting data including a second identifier associated with a vote cast by the voter, and voting information indicating the vote. Each voting server further includes a second synchronizer that synchronizes a second blockchain including second transaction data and dummy transaction data with at least one other voting server. The terminal transmits the authentication data to each authentication server and transmits the voting data to at least one of the voting servers.
