Abstract: A control method according to the present disclosure is executed by a first server of servers in a system including one or more IoT devices and the servers. The method includes: obtaining first transaction data including malfunction information indicating that one of the IoT devices is malfunctioning, and time information indicating a time when the IoT device has obtained the malfunction information; transferring the obtained first transaction data to second servers different from the first server; executing, together with the second servers, a first consensus algorithm for an agreement on an authenticity of the first transaction data; and recording a block containing the first transaction data in a distributed ledger of the first server, when the authenticity of the first transaction data is verified by the first consensus algorithm.

Abstract: A management system includes: a right holder information storage unit which stores right holder information about a right holder entitled to use a delivery locker device; an agreement formation unit which creates a block of a blockchain that includes a processing instruction, and stores the block into a block storage unit; a terminal device which transmits an assignment processing instruction; a process execution unit which, when obtaining the assignment processing instruction included in the block, updates the current right holder included in the right holder information; and a condition checking unit which, when determining that the condition for assignment fails to be met, creates a return processing instruction and transmits the return processing instruction to the agreement formation unit. When obtaining the return processing instruction included in the block, the process execution unit updates the right holder information.

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: In a fraud-detection method for use in an in-vehicle network system including a plurality of electronic control units (ECUs) that exchange messages on a plurality of networks, a plurality of fraud-detection ECUs each connected to a different one of the networks, and a gateway device, a fraud-detection ECU determines whether a message transmitted on a network connected to the fraud-detection ECU is malicious by using rule information stored in a memory. The gateway device receives updated rule information transmitted to a first network among the networks, selects a second network different from the first network, and transfers the updated rule information only to the second network. A fraud-detection ECU connected to the second network acquires the updated rule information and updates the rule information stored therein by using the updated rule information.

Abstract: A method for a fraud detecting controller connected to networks for communication by a plurality of controllers, includes, storing fraud detection rules, determining whether a message transmitted on the network connected to the fraud detecting controller conforms to the rules, receiving data including updated fraud detection rules and network type information indicating one network type to which the updated fraud detection rules are to be applied; and determining whether a vehicle having an on-board network is running, the on-board network including the plurality of controllers. When the vehicle is running, additionally determining whether the network type information indicates a drive network which is connected to a controller related to vehicle travel, when the network type information indicates the drive network, not updating to the updated fraud detection rules, and when the network type information does not indicate the drive network, updating to the updated fraud detection rules.

Abstract: An authentication server authenticates a voter using authentication data including a first identifier (ID) associated with the voter and authentication information regarding the voter. The authentication server further synchronizes a first blockchain. The first blockchain includes first transaction data indicating that the voter has been authenticated with one or more of other authentication servers. A voting server receives, from a terminal, voting data including a second ID associated with a vote cast by the voter and voting information indicating the vote. The voting server synchronizes a second blockchain including, as second transaction data, the voting information included in the voting data with one or more of other voting servers. The terminal transmits the authentication data to the authentication server and, after the authentication is successfully completed, transmits the voting data to the voting server.

Abstract: A fraud detection method for use in an in-vehicle network system including a plurality of electronic control units that communicate with one another via an in-vehicle network is provided. The method includes receiving at least one data frame sent to the in-vehicle network, verifying a specific identifier in the received data frame only when the received data frame is event-driven data and a state of a vehicle having the in-vehicle network system mounted therein is a predetermined state, detecting the received data frame as an authenticated data frame when the verifying is successful, and detecting the received data frame as a fraudulent data frame when the verifying fails. The predetermined state of the vehicle is the vehicle traveling.
