Abstract: Provided is a fraud detection rule updating method enabling the updating of rules that serve as the basis for detecting malicious frames as necessary in an on-board network system. In an on-board network system equipped with multiple electronic control units (ECUs) that communicate via buses and fraud detecting ECUs that determine, based on fraud detection rules, whether messages transmitted on the buses conform to the rules, a fraud detection rule updating method is used in which delivery data including updated fraud detection rules is received from a server external to the on-board network system, and if a certain update condition is satisfied, the fraud detection rules in a fraud detecting ECU are updated to the updated fraud detection rules.

Abstract: A control method according to the present disclosure is performed by one of a plurality of servers each including a distributed ledger and includes: obtaining request transaction data including an analysis request identification (ID) uniquely identifying a request for analysis, and an access method for accessing relevant information usable for the analysis; and recording a block including the request transaction data into the distributed ledger. The control method further includes: obtaining analysis transaction data including an analysis result corresponding to the analysis request ID, log information associated with the analysis result, and threat intelligence information serving as a basis of the analysis result; obtaining a verification result for the analysis transaction data; generating a block including the analysis transaction data; and when the verification result indicates that the validity of the analysis transaction data has been verified, recording the block including the analysis transaction data into the distributed ledger.

Abstract: An information management method collects log information of one or more home electrical apparatuses corresponding to service providers. Display screen data is generated which indicates a status of the log information. The display screen data includes groups of information which each contain information on an apparatus, a service provider corresponding to the apparatus, and log information output from the apparatus. Provision of the log information of each group is individually selectable. The display screen data is provided via a network to a display terminal that performs access to a server device. Information is received from the display terminal, which indicates that selection on whether or not provision of the log information is performed. Provision of the log information is not performed on the selected group when a determination is made that refusal of provision of the log information on the selected group is performed.

Abstract: A control method in which each of an Internet of things (IoT) device and a user who uses the IoT device has a digital account includes: obtaining first transaction data for allowing the user who used the IoT device to transfer a first amount corresponding to a usage amount of the IoT device; specifying, from the first transaction data obtained, the digital account of the IoT device that is associated with an identifier uniquely assigned to hardware of the IoT device; and transferring the usage amount of the IoT device to the digital account of the IoT device by deducting the first amount from the digital account of the user and adding the first amount to the digital account of the IoT device based on the first transaction data obtained.

Abstract: A control method according to the present disclosure includes: receiving, from a terminal operated by a first user who is one of parties that have concluded a first contract, first transaction data that includes a first smart contract corresponding to the first contract and a first electronic signature associated with the first user; executing a consensus algorithm with a plurality of other servers; and recording a block including the first transaction data in a distributed ledger. The first smart contract includes (i) content of the first contract which is a main contract, (ii) a variable that is provisional and used for identifying a second smart contract corresponding to a second contract which is to be newly concluded as a sub contract of the first contract, and (iii) a condition for creation of the second smart contract.
