Abstract: A service server generates a first smart contract programmed to be capable of executing provision of an incentive to a user when a goal indicated by generated challenge content generated is achieved, generates first transaction data including the first smart contract, and transmits the data to a first authentication server. The first authentication server executes a consensus algorithm and records the first transaction data in a distributed ledger to run the first smart contract. The first authentication server notifies a device used by the user of the challenge content. The first authentication server obtains, from the device, second transaction data including first challenge content selected to be registered by the user, and records the second transaction data in the distributed ledger by executing a consensus algorithm.

Abstract: A control method to be executed by a first device includes: receiving identification information identifying a second device from the second device by near-field communication; determining an evaluation value indicating appropriateness of the processing executed by the second device, with reference to a storage device that stores history information indicating processing executed by the second device; and restricting the near-field communication with the second device, based on the evaluation value determined.

Abstract: A control method according to the present disclosure is a method for controlling a first terminal carried by a first user and capable of communicating with a server via a network and includes: establishing short-range wireless communication by the first terminal with a second terminal carried by a second user; requesting the second terminal by the first terminal via the short-range wireless communication to provide item information, which is information related to at least one item included in one or more items worn by the second user, or requesting the server by the first terminal via the network to provide the item information, using identification information of at least one item that has been obtained upon the establishment of the short-range wireless communication; obtaining the item information by the first terminal; and transmitting, to the server, item positive-obtainment information indicating that the item information has been obtained.

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: A method includes: acquiring transaction data that includes value information regarding a value to be transferred from a second user to a first user; executing a first smart contract recorded in a first blockchain by recording the transaction data in the first blockchain; and executing a second smart contract recorded in a second blockchain different from the first blockchain based on the first smart contract. The second smart contract is a smart contract for transferring at least a portion of the value to be transferred from the second user to the first user, from a first account held by the first user to a third account held by a third user.
