Abstract:
The present disclosure provides a management method for software versions to improve transaction safety of software. In the management method, among management apparatuses, a first token management apparatus obtains request information indicating a requested version requested by a user, and first transaction data indicating that the user provides predetermined number of tokens to a software developer who has developed the requested version is stored in distributed ledgers through execution of a consensus algorithm by the management apparatuses.
Abstract:
A vehicle in a driving management system including one or more authentication servers and one or more vehicles capable of switching between a manual driving mode and an automatic driving mode is provided. The vehicle includes a communication unit that communicate with at least one authentication server of the one or more authentication servers, and a detecting unit that detects switching between the manual driving mode where manual driving is performed, and an automatic driving mode where automatic driving is performed, based on a message issued by at least one of the plurality of electronic control processors. The vehicle also includes a generating unit that generates transaction data including information indicating the detected switching, and an identifier indicating the vehicle, and transmits, to the at least one authentication server, the transaction data.
Abstract:
A control method includes: receiving first transaction data related to a sign-up for service and storing the first transaction data received into the distributed ledger included in each of the plurality of servers, the service offering, if a goal condition predetermined for the service is satisfied, a token to a participant that is a user who signs up for the service; storing, into the distributed ledger, second transaction data indicating that the user is offered the token predetermined for the service, if it is determined that the goal condition is satisfied; and storing, into the distributed ledger, third transaction data indicating that the user is offered a deposit that is a temporary token predetermined for the service, at a predetermined timing included in a period from the storing of the first transaction data into the distributed ledger until when determination of whether the goal condition is satisfied is performed.
Abstract:
The present disclosure provides a control method that is executed by one of a plurality of servers in a content management system that includes: the plurality of servers that own distributed ledgers; and a storing device that stores content, the control method including: acquiring transaction data that indicates that a providing device has provided content and includes at least identification information of the content provided by the providing device; and storing the transaction data acquired into the distributed ledgers of the plurality of servers.
Abstract:
An information providing method includes: transmitting, in response to a user's access using a display terminal, first display data, including multiple check items to be used by the user who is choosing a service provider to be allowed to use a target device's log information to check the reliability of that service provider, to a display terminal; receiving selection information representing a set of selected check items including at least one check item selected from the check items included in the first display data using the display terminal; transmitting second display data representing a set of reference check items including, among multiple check items received from other users' terminals, check items which are either similar to, or the same as, check items included in the set of selected check items represented by the selection information, to the display terminal; afterward receiving editing information representing an edited set of check items obtained by editing the set of selected check items, from the display terminal after that; and providing the log information to a computer of the service provider who has been chosen based on the edited set of check items.
Abstract:
In order to enhance security of a parked vehicle, an image transmitting device to be mounted on a vehicle includes: a checking unit that checks, at a parking place of the vehicle, communicability with an external device outside of the vehicle, that is, whether an image can be transmitted from the parking place to the external device; a providing unit that provides notification information based on a result of the checking by the checking unit; a capturing unit that captures an image while the vehicle is parked; and a transmitting unit that transmits the image captured by the capturing unit to the external device.
Abstract:
An authentication method for at least one of a plurality of devices connected to a HAN includes checking, with a first device among the plurality of devices, validity of a second device using a CRL including attribute information regarding the second device among the plurality of devices, and revoking, with the first device, the second device if a result of the checking is negative.
Abstract:
A data providing method is carried out by a computer (460) built in a data processing system (1) which is designed to collect log information from electronic devices through a network (30) and provide services based on that log information for authenticated users. The data providing method includes: receiving an air conditioner (102a, 102b)'s log information through the network; generating display data by reference to pieces of information which are included in the air conditioner's log information and which indicate (i) a preset temperature of the air conditioner, (ii) an outdoor temperature outside a living space in which the air conditioner is installed, and (iii) an indoor temperature of the living space in which the air conditioner is installed, the display data representing a trend of change of a turnaround time that indicates how long it takes from when the air conditioner starts operating until the indoor temperature reaches the preset temperature; and providing the display data for an authenticated user's display terminal (130a, 130b).
