    Abstract: In a data distribution method according to the disclosure, first authentication servers and a first data server belong to a first group, and second authentication servers and a second data server belong to a second group different from the first group. A first authentication server obtains first transaction data that includes a data obtaining request indicating a request for obtaining or referring to data pertaining to an apparatus, and records a block including the first transaction data into its distributed ledger belonging to the first group. A second authentication server obtains the first transaction data, and records the block including the first transaction data into a distributed ledger belonging to the second group. The first authentication server causes the first data server to transfer the data pertaining to the apparatus held therein to the second data server or to make such data available for reference by the second data server.

    Abstract: This control method, etc., are a control method for an anomalous data sensing system including at least a plurality of authentication servers and include: sensing whether data obtained from a device is not anomalous; obtaining first transaction data including information indicating the data; verifying, by a first authentication server included in the plurality of authentication servers, the first transaction data obtained, when the data is sensed as not being anomalous; and recording a block including the first transaction data into a distributed ledger when an agreement about validity of the first transaction data is reached using a consensus algorithm.

    Abstract: A fraud detecting method for use in an in-vehicle network system including a plurality of electronic control units that communicate with each other via a network includes detecting whether a state of a vehicle satisfies a first condition or a second condition, and switching, upon detecting that the state of the vehicle satisfies the first condition or the second condition, an operation mode of a fraud-sensing electronic control unit connected to the network between a first mode in which a first type of detecting process for detecting a fraudulent message in the network is performed and a second mode in which the first type of detecting process is not performed. Moreover, in the second mode, a second type of detecting process having a different degree to which a fraudulent message is detectible than the first type of detecting process is performed.

    Abstract: A vehicle anomaly detection server includes: a communicator that communicates with a vehicle to receive a log of an in-vehicle network in the vehicle; a processor; and a memory including at least one set of instructions that, when executed by the processor causes the processor to perform operations including: selecting, when information indicating that an anomaly is occurring to a first vehicle among vehicles is obtained by the processor, an anomaly-related vehicle from among the vehicles based on the anomaly, the first vehicle being the vehicle that communicates with the communicator; transmitting, to the anomaly-related vehicle via the communicator, a first request to transmit a log of an in-vehicle network in the anomaly-related vehicle; and determining whether an anomaly is occurring to the anomaly-related vehicle, based on information indicated by the log transmitted from the anomaly-related vehicle and received by the communicator.
