    Abstract: A verification method includes: obtaining log information items generated in a device; storing the log information items in storage, and storing, in a blockchain, converted information items obtained by converting the log information items; and conducting, at a predetermined frequency, verification as to whether at least one of a target log information item or a target converted information item has been tampered with, based on the target log information item and the target converted information item, the target log information item being included in the log information items and targeted for verification, the target converted information item being included in the converted information items and corresponding to the target log information item. A higher frequency is determined as the predetermined frequency when a time point at which the target converted information item was stored in the blockchain is closer to a current time at which the verification is conducted.

    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.
