Abstract:
An information presenting device (100) presents image information; an operative device (200) accepts a predetermined input operation during the presentation of the image information; a guide information managing device (300) stores date and time information indicating a date and a time at which the input operation is accepted, image specifying information specifying image information presented when the input operation is accepted, and guide destination information indicating a guide destination to which the user is guided is stored in a database in association with one another, the guide destination information being specified by the date and time information, and the image specifying information; and a guide device (400) presents the guide destination information in response to a request from the user.
Abstract:
An information processing device performs: acquiring a user ID, desired time information associated with the user ID and indicating a desired time or a desired timeframe for receiving a commodity, and ordered commodity information associated with the user ID; determining, on the basis of the desired time information and the ordered commodity information, whether an ordered commodity indicated by the ordered commodity information is receivable at the desired time or in the desired timeframe; deciding a receipt time or a receipt timeframe for the ordered commodity when the ordered commodity is determined to be receivable at the desired time or in the desired timeframe; and outputting receipt time information indicating the receipt time or the receipt timeframe.
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.
Abstract:
In a data management method, a plurality of servers store, in a distributed ledger, at least one instance of transaction data each including record information; the record information includes a record of at least one data set; and each data set includes at least one instance of data, among a plurality of instances of data generated by a plurality of devices, satisfying a condition corresponding to the data set. The data management method includes a first terminal owned by a first user of a target data set, or a second terminal owned by a second user of the target data set, performing the following: obtaining the record of at least one similar data set similar to the target data set from the record information; and determining a value of the target data set based on the record obtained.
Abstract:
A control method according to the present disclosure is a method for controlling an information spot placed on at least one of a traffic light and roadside equipment and includes: obtaining, from a first mobile body via short-range wireless communication, first information obtained from a first path along which the first mobile body has traveled to reach the location of the information spot and indicating a situation on the first path; obtaining information related to the destination of a second mobile body, which is different from the first mobile body, from the second mobile body via the short-range wireless communication; and transmitting the first information to the second mobile body when it is determined that the second mobile body is to travel along at least a part of the first path to reach the destination.
Abstract:
A control method includes: obtaining first transaction data that includes first information on a first contract made between a first user and a second user; storing the first transaction data obtained into the distributed ledger; obtaining second transaction data that includes second information on a second contract made between the first user and a third user; storing the second transaction data obtained into the distributed ledger; obtaining third transaction data using the first information and the second information, when one of the first transaction data and the second transaction data is associated with a remaining one of the first transaction data and the second transaction data, the third transaction data including third information on a third contract made between the second user and the third user; and storing the third transaction data obtained 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 includes obtaining, from a terminal, reservation information including use start date and time of an electric-powered vehicle that a first user hopes to use; obtaining an amount of remaining battery of the electric-powered vehicle; determining, based on the amount of remaining battery, whether an amount of remaining battery of the electric-powered vehicle is no less than a predetermined value at the use start date and time; and transmitting, to the terminal, notification information indicating a result of the determining. For example, the determination includes calculating, based on a predetermined charging characteristic unique to a battery of the electric-powered vehicle, an amount of remaining battery to be held by the electric-powered vehicle at the use start date and time upon the electric-powered vehicle being charged at a charging station; and determining whether the amount of remaining battery of the electric-powered vehicle is no less than the predetermined value.
Abstract:
A control method is executed by one server out of a plurality of servers, each managing one of a plurality of distributed ledgers. The control method includes receiving first transaction data from a measured-value server over a network, the measured-value server providing, for each of one or more parameters for determining a price for a variable-price service, a measured value that corresponds to the parameter, and the first transaction data including the one or more parameters, the measured value, and a location and a time where and when the measured value is obtained; and transferring the received first transaction data to other servers different from the one server out of the plurality of servers and storing a first block including the first transaction data into a first distributed ledger managed by the one server.
Abstract:
A server apparatus receives a device ID indicating one electrical home appliance among one or more electrical home appliances and a gateway ID indicating that the one electrical home appliance belongs to a same owner, a same group, or a same home as the one or more electrical home appliances, determines whether or not the one electrical home appliance is a newly connected electrical home appliance, using a management database that manages device IDs indicating the one or more electrical home appliances and the gateway ID, and when it is determined made that the one electrical home appliance is a newly connected electrical home appliance, provides an information device, which is associated with the gateway ID and which differs from the one electrical home appliance, with notification information for confirming whether or not it is to be permitted to collect the log information from the one electrical home appliance.
