Description

The present invention relates to a measurement information trading system.

As described in Patent Document 1, there is a system that uses measurement information sent to a server via a network by collecting the information on the server. Furthermore, it is assumed that information in which information on an information provider and measurement information of the information provider are linked is traded and used between the provider and the user. For example, providing companies and government offices with information that links the information provider's information, such as the area where the information provider lives and family structure (such as a family of four), with the information provider's family's power consumption. etc. are assumed.

By the way, in the technique described in Patent Document 1, information is centrally managed by a server, which incurs costs for the server itself, its installation location, and maintenance. Therefore, the cost of collecting information to utilize measurement information also increases.

The inventor of this case attempted to solve this problem by intensively studying this point. The problem to be solved by the present invention is to provide a system that allows information provider information and its measurement information to be traded at low cost.

In order to solve the above problems, we provide a recording means that records information in a distributed ledger in a peer-to-peer network by linking information provider information and measurement information at the information provider's building, and an information user and viewing means for viewing information recorded by the recording means.

Further, it is preferable that the information user has a configuration including a search means for extracting the input information from the information recorded in the distributed ledger by inputting information that the information user desires to view.

Further, it is preferable that the system includes a contract means for automatically granting compensation for the information to the information provider using a smart contract when the information user obtains the information extracted by the search means.

Moreover, it is preferable that the search means is configured to have a function of inputting the measurement time of the measurement information that the information user desires to view.

In addition, the contract means divides the compensation determined for the measurement information proportionally based on the number of information providers targeted in the search results by the search means, and distributes the said amount to the targeted information providers. It is preferable to have a configuration in which a consideration is given in accordance with the above.

In addition, the search means has a function for inputting the number of information providers that the information user desires to view, and the contract means determines the number of information providers that the information user desires to view as a result of the search by the search means. If the number of target persons exceeds 1, it is preferable to choose a configuration in which information providers are selected at random.

In addition, there is a request means for requesting permission from the information provider of the information that the information user wishes to view, and information that links the information provider information and its measurement information through the operation of the information provider. It is preferable to have a configuration including a permission means for permitting information users to view the information.

In addition, the information user is provided with a permission means that allows the information user to view information linking the information provider information and its measurement information through the operation of the information provider. It is preferable to have a configuration that includes a function to input information provider information and its measurement information to be recorded in the information provider.

Further, it is preferable to have a configuration including a notification means for notifying the information provider of the viewing information.

According to the present invention, it is possible to provide a system that allows information provider information and its measurement information to be traded at low cost.

A mode for carrying out the invention will be shown below. As can be understood from what is shown in FIG. 1, the measurement information trading system 10 of the present embodiment links information provider information and measurement information in the information provider's building, and performs peer-to-peer exchange. It includes a recording means for recording information in the distributed ledger 1 in a network of peers, and a viewing means for an information user to view the information recorded by the recording means. Therefore, there is no need for a server to record information, and information in which information provider information and its measurement information are linked can be provided to information users at low cost.

For recording in the recording means, the information provider may link provider information and measurement information and record it in the distributed ledger 1, or the provider information and measurement information may be recorded in the distributed ledger 1 at the same time. It may also be possible to link it with this.

Here, Peer to Peer will be explained. Peer-to-peer is one of the architectures for communicating between a large number of systems, and is a basic communication system in which peers (friends, etc.) communicate with each other. In this embodiment, they are connected via a peer-to-peer network.

In this embodiment, information to be shared in a peer-to-peer network is recorded in a distributed ledger 1. When predetermined information is written to the distributed ledger 1 of one system, the same distributed information is written to the distributed ledgers 1 held by all other systems through the peer-to-peer network.

For example, a blockchain method can be used as a technology for such a distributed ledger 1 in order to prevent information from being tampered with. In the blockchain method, "blocks" containing "records of transactions" are sequentially added to a "chain." Each block that makes up a blockchain consists of a ``header'' that contains information about the block and the previous block, and ``transactions'' that record a list of transactions that took place within a certain period of time. In the blockchain, all transaction records from the past are recorded, so if an attempt is made to commit fraud, it is necessary to rewrite all blocks since the fraud, which requires a large computational load and makes tampering difficult. Each system connected to a peer-to-peer network will then distribute and share the information sent by one peer. In addition to the blockchain method, a DAG (Directed Acyclic Graph) method can also be used.

Typical information providers of the present invention are residents and businesses. The company may be a store such as a convenience store. In addition, typical information provider information includes address (possibly including information on prefectures and municipalities), type and number of electrical equipment, existence and type of power generation equipment, installation location of measuring device 3 (1 floor, second floor, etc.), type of building (wooden, reinforced concrete, etc.), etc. If the information provider is a resident, the family structure (such as a family of four) may be used as the information provider information, and if the information provider is a company, the company size and industry may be used as the information provider information.

Typical measurement information is measured by the measuring device 3, and includes power consumption, power generation (power generation using renewable energy such as sunlight), purchased power, sold power, remaining amount of storage battery, and earthquake information ( (seismic intensity, time of occurrence, etc.), lightning information, temperature, humidity, etc. It is preferable that all of the measurement information includes information corresponding to the measurement date and time. Typical examples of information users who use such information include government offices and companies.

Here, the simplest flow of using the measurement information trading system 10 of this embodiment will be explained. As shown in FIG. 2, after the recording means records on the distributed ledger 1, the user views it using the viewing means, and then the transaction ends. Although this flow is the simplest, it is of course possible to use other steps.

For example, in the example shown in FIG. 3, after the recording means records on the distributed ledger 1, when the information user inputs the necessary information using the search means, the information is extracted from the distributed ledger 1 using the search means. do. The user views the extracted results using the viewing means, and the transaction ends after consideration is given through the contract means.

In this way, if the information user inputs the information that he or she wishes to view, and the configuration is equipped with a search means that extracts the input information from the information recorded in the distributed ledger 1, the information usage This is preferable because it allows the person to obtain necessary information.

It is preferable that this search means has a function for inputting the measurement time of the measurement information that the information user wishes to view, since this allows the user to select the measurement time such as real-time measurement information or measurement information at a specific time in the past.

Further, it is preferable that the system includes a contract means for automatically granting compensation for the information to the information provider using a smart contract when the information user obtains the information extracted by the search means. Since there is no intermediary work between the information provider and the information user, there is no need for third party intermediary fees required for contract work, so even if the consideration is low, it can be given to the information provider. This is because it can be done. In this case, an information provider sets conditions regarding information provision (such as access rights and information type) using an application, and the distributed ledger 1 or server that manages the application generates smart contract conditions.

Note that a smart contract is a contract exchanged on a distributed ledger 1 such as a blockchain network. It is a program that is written in digital format and automatically executes processing according to preset contents when the conditions set as contract contents are achieved. Blockchain has a mechanism that maintains the reliability of information without the need for a central management system. Therefore, by generating a smart contract, users can conduct commercial transactions between users without going through a server or the like that mediates commercial transactions.

The contract means divides the compensation determined for the measurement information proportionally based on the number of information providers targeted in the search results by the search means, and pays the prorated compensation to the targeted information providers. It is preferable that the This is because many information providers receive compensation and feel benefited.

Examples of consideration include virtual currency, electronic money, and electronic points. In the case of virtual currencies, it is preferable to use ones with smart contract functions such as Ethereum.

There are no particular restrictions on the contract method, and a form of free access that is open to anyone may be adopted, but since personal information will be provided, the information will be provided to the user if the information provider gives permission. It may also take the form of limited access. In the latter case, it is preferable that the measurement information transaction system 10 is provided with a permission means for providing information to the user when the information provider gives permission. Furthermore, it is preferable to individually grant access rights to personal information to users, and to hash the access records by information users and record them on a blockchain for management.

The permission means may be able to selectively permit disclosure of information. In this case, as can be understood from FIG. 4, information that can be disclosed may be input and recorded in the distributed ledger 1. In this way, if the permission means is provided with a function for inputting the information provider information and its measurement information that the information provider records in the distributed ledger 1, the provider can allow the user to view the information in advance. Since information can be selected, information that the provider wants to keep confidential does not need to be disclosed.

When restricting information users, it may be possible to have a system in which information users are granted authority to companies or industries selected by the information provider in advance, or if an information user requests viewing, the information provider can It may also be a mechanism for determining whether or not to grant viewing authority to the information user. In the former case, as can be understood from the illustrations in FIGS. 5 and 6, it is preferable to allow information users who can view the information to be input in advance using the permission means. In the latter case, as can be understood from FIGS. 7 to 9, it may be determined whether or not to permit each viewing request. In this way, the information user uses the request means to request permission from the information provider of the information that the information user wishes to view, and the information provider's operation to link the information provider information and its measurement information. If the configuration includes a permission means for allowing information users to view the information, the information provider can select the information users who can view the information, thereby preventing unnecessary leakage of personal information. can.

For example, an information provider records information on providers who can provide information and measurement information in advance in the distributed ledger 1, and when an information user requests multiple information providers to view the desired information, A deadline may be set for the information provider to respond, and information from information providers approved within the deadline may be subject to the contract.

In addition, the search means has a function for inputting the number of information providers that the information user desires to view, and the contract means determines the number of information providers that the information user desires to view as a result of the search by the search means. If the number of subjects exceeds the target number, it is also preferable to select information providers at random.

Preferably, the recording means and the permission means are operated by an application installed on a terminal such as a smartphone or a PC on the information provider side. Further, it is preferable that the search means is operated by an application installed on a terminal such as a smartphone or a PC of the information user. Further, it may be another communication device that cooperates with the measuring device 3. For example, the above means may be provided in a communication device that obtains electric power from a conductive part of a distribution board. Depending on the measurement information, such a communication device and a terminal application may be used together.

In addition, after the information user has viewed the information, there is a notification means that notifies the information provider by feeding back information related to the viewing, such as the information user's information, the viewed information provider information and its measurement information, and when the information was viewed. There may be. In this way, by providing a notification means for notifying the information provider of viewing information, the provider can obtain information on who viewed what information and when, thereby increasing the transparency of transactions.

Although the present invention has been described above using the embodiments as examples, the present invention is not limited to the above embodiments, and can be modified in various ways. For example, it is also possible to change the order of flows.
