-Collecting department-
The collection unit 111 collects the first history information regarding the history of the transfer from the plurality of first devices used by each of the plurality of businesses that execute the transfer of value.

Here, a configuration example of the first history information will be described with reference to FIG. 4A. As shown in FIG. 4A, the first history information is, for example, the transfer identification information of each transfer issued for each first business operator, the transfer date and time indicating the date and time when the transfer was executed, and the transfer as the transfer history. It may include original / relocation account identification information, relocation location indicating the device on which the relocation was performed, relocation details, related history indicating the history of processing related to the relocation, related data indicating the data related to the relocation, and other external information. ..

The transfer identification information may be, for example, a reference number for each first business operator, a reference number for a remittance transaction, a slip number for a sales slip, or the like. The account identification information may be, for example, the transferee name or recipient name of the transfer, the customer ID or account number issued to the customer by the first business operator, or the like.

The first history information may include, for example, credit information. Here, "credit information" is information indicating the credit of the parties involved based on the transfer. Here, the "participant" is a person involved in the transfer, for example, a user of the transfer source / destination, a first business operator who executes the transfer, and the like. Credit information includes, for example, the history of approval and refusal of value transfer, the history of evaluation at the time of transaction (evaluation from transaction parties such as "like"), the result of customer confirmation / corporate confirmation at the time of transfer, External information such as home delivery and mail order may be included. The credit information may be, for example, in the case of transfer by credit card payment, the credit status to the user when using the credit card.

As another example of the above-described embodiment, the collecting unit 111 stores the first history information stored in the library provided by the API or SDK implemented by the information providing device 100 or the business operator device 200. You may instruct the information providing device 100 to provide the information. From the API or the library, the collecting unit 111 may acquire the first history information as a response to this instruction by the information providing device 100.

As another example of the above aspect, the collecting unit 111 may be realized by the information providing device 100 participating as a node in the network of the blockchain when the value is a virtual currency using a blockchain. The collection unit 111 directly acquires the history of transfers written in the blockchain distributed to each node.

For example, the collecting unit 111 may collect consent information from the operator device 200 or the user device 300 on the premise of collecting the first history information. Here, the "agreement information" is information indicating that the customer agrees to provide the first history information of the transfer regarding the customer of the first business operator from the business operator device 200 to the information providing device 100. .. The consent information may include, for example, matters to be agreed. The matters to be agreed are, for example, when at least a part of the first history information can be provided, whether it can be used at the provider, or when at least a part of the first history information can be provided and used. The purpose of use (for example, provision / disclosure to a third party, etc.) may be included.

The timing at which the collection unit 111 collects consent information is (a) when the customer of the business operator registers as a user of the information providing service, and (b) when the application installed on the user device 300, terms of use, etc. are changed. , (C) Every time the transfer of value is executed, etc., the timing can be considered.

The collecting unit 111 may extract information such as user data, transaction data, or account data from the collected first history information. As another example, the collecting unit 111 may acquire user data, transaction data, account data, or the like from the business operator device 200 or the user device 300 in addition to the first history information.

"User data" is data about a transfer source or destination user. User data includes, for example, "user identification information", "name", "telephone number", "address", "email address", "personal number (my number)", "gender", "date of birth", etc. for identifying the user. It may include so-called personal information of the user.

The user data includes, for example, the user's "license number" and "card number", the account data of the account held by the user, and the device information of the user device 300 used by the user (for example, MAC address, IP address, serial number, etc.). It may be included.

The user data may include, for example, biological information regarding the biological characteristics of the user (for example, user's facial image data, fingerprint information, eyeball iris information, voiceprint information, etc.).

The user data may include, for example, location information (for example, GPS data, etc.), Web history information (for example, browsing history, search history, cookie information, etc.), purchase history information of products on an EC site, and the like.

"Transaction data" is data related to a transaction in the case of transfer by transaction. The transaction data includes, for example, "transaction identification information" for identifying the transaction to be paid, "payer name" indicating the name of the customer who is the payer, "recipient name" indicating the name of the payee, and the status of payment settlement. "Payment settlement status" indicating (for example, "unbilled" / "billing completed" / "payment settlement instruction completed" / "payment completed", etc.), service name or product name to be paid, amount to be paid in the transaction to be paid It may include data items such as "payment amount (payment amount)" indicating "payment amount", "payment method" indicating a payment method such as card payment, electronic money payment or bank transfer. The transaction data may also include data items relating to the account data of the payer's account or the payee's account.

"Account data" is information for managing each account. The account data includes, for example, "bank identification information", "account type", "account number", "name" for identifying the target bank, "account ID" for identifying the account owned by the payer or recipient, and an account. Includes "account balance" indicating the account balance such as the total amount deposited in, or "transaction content" indicating the content of transactions using the account.

The transaction content includes, for example, a "deposit / withdrawal history" indicating a deposit / withdrawal history. The deposit / withdrawal history is, for example, a "deposit / withdrawal ID" for identifying each deposit / withdrawal, an ID of the bank card used for deposit / withdrawal, and an ID indicating the other party of deposit / withdrawal of the credit card company in the withdrawal of the credit card. "Customer ID" indicating etc., "Deposit / withdrawal date / time" indicating the date and time of deposit / withdrawal, "Deposit amount" indicating the amount deposited in the account or "Withdrawal amount" indicating the amount withdrawn from the account, etc. include.

-Recording section-
The recording unit 112 records the tag information in the storage unit in association with the first history information of the transfer based on the first history information collected by the collection unit 111. Here, "tag information" is information representing at least one of value or transfer of value. In other words, the tag information is information that gives meaning to the items included in the first history information. As shown in FIG. 4B, the tag information may be, for example, a person involved, a transfer date and time, a transaction type, an authentication type, a transfer location, or the like.

There may be a plurality of tag information associated with the first history information by the recording unit 112. Further, the recording unit 112 may give priority to each tag information when it is extracted by the extraction unit 114.

For example, in the example shown in FIG. 2, the recording unit 112 adds tag information indicating the transaction type “remittance transaction” to the first history information for each of the transfer of value (a), (d), and (e) by remittance. It may be associated and stored.

The recording unit 112 may record, for example, the tag information representing the participants in association with the first history information of the transfer.

The transfer may include, for example, a first transfer and a second transfer. For example, the recording unit 112 may record the first history information of each of the first transfer and the second transfer in the storage unit in association with each other.

The "second relocation" is a relocation that follows the first relocation. Specifically, the second transfer is a transfer in which the account of the transfer destination of the first transfer and the account of the transfer source match. Further, the second transfer may be, for example, a transfer having a certain relationship with the first transfer. In other words, the second transfer is a transfer that satisfies a predetermined condition for determining whether or not there is a certain relationship with the first transfer. Details of the predetermined conditions will be described in the second transfer determination unit described later.

For example, the recording unit 112 may record the first history information of each of the first transfer and the second transfer in the storage unit in association with each other.

The recording unit 112 may include a specific unit 1121 and a hash calculation unit 1122.

The identification unit 1121 identifies the relocation route connecting the first relocation and the second relocation.

The hash calculation unit 1122 calculates the hash value of the first history information of each transfer on the transfer route specified by the specific unit 1121.

For example, the recording unit 112 records the hash information representing the hash value of each transfer calculated by the hash calculation unit 1122 in the storage unit in association with the first history information of the other transfer succeeding each transfer.

In associating the first history information with each other in the recording unit 112, for example, an electronic signature and a hash pointer used in the blockchain technology may be used.

First, the hash calculation unit 1122 calculates the first hash value (electronic signature) from the first history information of the first transfer using a predetermined hash function. Next, the hash calculation unit 1122 associates the hash information of the first hash value with the first history information of the second transfer. Next, the hash calculation unit 1122 includes the first hash value in the first history information of the second transfer and calculates the second hash value using a predetermined hash function. Next, the hash calculation unit 1122 associates the hash information indicating the second hash value with the first history information of the transfer following the second transfer. In this way, the hash calculation unit 1122 includes the hash value of the preceding transfer on the transfer route in the first history information of the subsequent transfer, and calculates the hash value.

The "predetermined hash function" may be, for example, a cryptographic hash function (one-way hash function), MD5, SHA-1 to 3, or the like.

The range of the first history information used as the calculation source of the hash value in the hash calculation unit 1122 may be limited to a part. The hash value may be calculated from, for example, only the account identification information of the transfer source / transfer destination included in the first history information.

As another example, the recording unit 112 has a hash of not only the first history information of the immediately preceding transfer but also the first history information of the transfer that has been preceded from a predetermined starting point to the first history information of the subsequent transfer. You may include the value. For example, in the example shown in FIG. 2, when the recording unit 112 calculates the hash value of the first history information of the transfer (d), the first history information of the transfer (d) is referred to the immediately preceding transfer (c). Not only the hash value of (a) and (b) that have preceded the hash value of (a) and (b) may be included.

According to the above configuration, the recording unit 112 makes it difficult to falsify the first history information recorded by the hash value collision difficulty / one-way in associating the first history information with each other in a plurality of transfers. Can be done. Therefore, according to the above configuration, the recording unit 112 can improve the security in recording the first history information.

In the above, an example of associating a hash value as a pointer has been described, but the present invention is not limited to this. For example, instead of the hash value, the transfer identification information included in the transfer first history information or the history identification information for identifying each of the first history information issued by the information providing system 1 may be used as a pointer.

When the validity determination unit 118 described later determines that the correction is valid, the recording unit 112 may reflect the correction in the first history information of the first transfer.

-Reception Department-
The reception unit 113 receives an information request from the user device 300 by designating a search key related to the transfer history and requesting the transfer history. The search key to be specified may be specified by combining a plurality of character strings or numerical values under AND / OR conditions.

The mode in which the reception unit 113 receives the information request may be any mode. The reception unit 113 may receive, for example, a message indicating this information request from the user device 300 via the communication unit 140. Further, the reception unit 113 may input and accept an information request from the screen of the information providing service displayed by the user device 300 (the screen of the information providing application or the Web browser). Further, the reception unit 113 may receive this information request by using the API or SDK library mounted on the information providing device 100 by the user device 300, for example, similarly to the collection unit 111.

The reception unit 113 may, for example, receive an information request from the user device 300 by designating a participant and requesting the credit rating of the participant, which will be described later.

The reception unit 113 may, for example, receive an information request from the user apparatus 300, which specifies a target and requests the target credit rating described later. Here, "specify the target" means, for example, when the target is a value, the type of value (for example, A coin, B pay, C point, etc.) may be specified, and it is held in a specific account. It may be a value (for example, total assets in the A coin account of user 1).

The reception unit 113 may receive, for example, a correction request from the user device 300, which is a correction request including user identification information for identifying the user and requests correction for the first transfer.

-Extractor-

The extraction unit 114 refers to the storage unit based on the tag information and the information request, and extracts the first history information of the transfer corresponding to the search key. For example, in the example shown in FIG. 2, when the search key “remittance transaction” is specified in the information request, the extraction unit 114 transfers the value associated with the tag information indicating “remittance transaction” (a). The first history information of (d) and (e) may be extracted.

For example, when the extraction unit 114 extracts the first history information of either the first transfer or the second transfer, the extraction unit 114 may also extract the other first history information.

According to the above configuration, the extraction unit 114 can extract the first history information of the second transfer having a certain relationship with the first transfer in addition to the first transfer corresponding to the search key. Therefore, according to the above configuration, the extraction unit 114 enables the user to collectively provide not only the transfer corresponding to the search key but also the transfer related to the transfer by the providing unit 115.

-Providing department-
The providing unit 115 provides the user apparatus 300 that has received the information request with the first history information extracted by the extracting unit 114. The mode in which the providing unit 115 provides the first history information to the user apparatus 300 may be any mode. The providing unit 115 may refer to or download the first history information from the screen of the information providing service displayed by the user device 300, for example. As another example, the providing unit 115 may transmit the data file of the first history information to the user device 300 via the communication unit 140.

According to the above configuration, the providing unit 115 can extract and provide the necessary relocation history collected from the operator device 200 according to the user's request. Therefore, according to the above configuration, the user can grasp the transfer of a plurality of values collectively.

The providing unit 115 may provide the user apparatus 300 with the party credit information indicating the party credit rating of the designated party, for example, based on the information request. Here, the "participant credit rating" is the degree of credit of each participant. The details of the creditworthiness of the participants will be described later in the creditworthiness calculation unit 116.

According to the above configuration, the providing unit 115 can provide the user with the fact-based participant credit rating calculated from the transfer history. Therefore, according to the above configuration, the user pays attention to transactions with participants with low creditworthiness of participants, and conversely, actively conducts transactions with participants with high creditworthiness of participants. Can be done. Therefore, according to the above configuration, it is possible to provide information that contributes to future value transfer by the user.

For example, the providing unit 115 may provide the user apparatus 300 with the target credit rating information indicating the target credit rating of the designated target based on the information request received by the receiving section 113.

According to the above configuration, the providing unit 115 can provide the user with the fact-based target credit rating calculated from the transfer history. Therefore, according to the above configuration, the user pays attention to transactions with a value whose target creditworthiness is lower than other values, and conversely, is positive when trading with a target person's creditworthiness higher than other values. You can go to. Therefore, according to the above configuration, the providing unit 115 can provide information that contributes to the future transfer of value to the user.

-Credit calculation department-
The credit rating unit 116 calculates the participant credit rating for each participant with reference to the storage unit based on the first history information and the tag information. First, the credit rating unit 116 assigns numerical values to, for example, the history of approval or refusal for the transfer of value indicated by credit information, the history of evaluation at the time of transaction, or the result of customer confirmation / corporate confirmation at the time of transfer. .. Next, the credit rating unit 116 assigns, for example, "+1" to the history of approval for transfer and "-2" to the history of refusal to transfer. Next, the credit rating calculation unit 116 may aggregate the assigned numerical values for each participant, and use the result of the aggregation as the participant credit rating. The credit rating unit 116 may, for example, calculate a statistical value from the result of this aggregation and use the calculated statistical value as the participant credit rating. Here, the "statistical value" may be, for example, an average value, a median value, a mode value, or the like.

The creditworthiness calculation unit 116 may calculate the target creditworthiness based on, for example, the calculated participant creditworthiness. Here, the "target creditworthiness" is the degree of credit for each value. Further, here, the “degree of credit for each value” may be, for example, the degree of credit for each type of value, or may be the value in a specific account.

For example, when calculating the target creditworthiness of A coin, the credit rating calculation unit 116 identifies a person involved in the transfer in a set period from the first history information of the transfer of A coin. Then, the credit rating calculation unit 116 may aggregate the participant credit ratings of the specified participants and use the result of the aggregation as the target credit rating of the A coin. The credit rating unit 116 may, for example, calculate a statistical value from the result of this aggregation and use the calculated statistical value as the target credit rating.

The second transfer determination unit 117 determines the presence or absence of the second transfer with reference to the storage unit. The second transfer determination unit 117 sequentially determines, for example, whether or not each of the transfers indicated by the first history information recorded in the storage unit satisfies a predetermined condition. When a transfer satisfying a predetermined condition is detected, the second transfer determination unit 117 determines that the detected transfer is a second transfer and "has a second transfer".

Here, with reference to FIG. 5, an example of the determination of the second transfer of the second transfer determination unit 117 will be described. The predetermined condition in the second transfer determination unit 117 may include, for example, that the execution is performed in the first predetermined period from the transfer date and time of the first transfer, as shown in FIG. 5A. Further, as shown in FIG. 5B, for example, the predetermined condition is the earliest after the first transfer among other transfers (transfers A to C) whose transfer source is the transfer destination (user 2 account) of the first transfer. It may include that it is an executed transfer (transfer A). As another example, it may be not only the transfer executed earliest but also the transfer executed up to the Nth (N is a natural number) in the order of earliest. As another example, the predetermined conditions are (A) transfer to a set transfer destination, (B) transfer of a value of more than / less than a set amount, and (C) a set transaction type. , Etc. may be included.

-Validity judgment unit-
The explanation will be continued by returning to FIG. When the reception unit 113 receives the correction request, the validity determination unit 118 determines whether or not the correction is valid based on the user identification information and the first history information of the first transfer and the second transfer. The validity determination unit 118 determines, for example, whether or not the first transfer to be corrected is a request of a person who is qualified to request correction. First, as a first step, the validity determination unit 118 transfers the user identified by the user identification information included in the correction request to the transfer source or transfer destination user identified by the account identification information indicated by the first history information of the transfer. Determine if it applies. If it is determined that the validity is applicable, the validity determination unit 118 determines that the validity in the first stage is "yes".

Next, as a second step, the validity determination unit 118 determines whether or not the content of the correction is appropriate. For example, in the example shown in FIG. 2, when the first transfer is transfer (a), the transfer (a) is not executed, that is, the A coin is not transferred from the user 1 account to the user 2 account, so that the history (a). ) Is requested to be canceled from the user device 300 of the user 2. In this case, the validity determination unit 118 transfers the transfer (c) whose transfer source is the account of the user 2 who is the transfer destination account of the first transfer when the transfer (a) is the first transfer. To specify. Then, the validity determination unit 118 determines the validity of the transfer (a) based on the first history information of the transfer (c). For example, when a correction is requested because the amount of A coin remitted to the user 2's account is not reflected in the total asset amount, the validity determination unit 118 will use the two users themselves after the transfer (a). Confirm the converted amount in the transfer (c) (conversion from A coin to B pay) transferred between the accounts of. If the amount converted in transfer (c) exceeds the amount remitted in transfer (a), the reason for this application may be judged to be unreasonable and the validity of the correction request may be determined to be "none".

-Memory unit-
The storage unit 130 stores the first history information, tag information, user data, transaction data and / or account data and the like. The storage unit 130 may store each information by using a database management system (DBMS) or may store each information by using a file system. When using the DBMS, the storage unit 130 may provide a table for each of the above information and manage each information by associating the tables with each other.

-Communication unit-
The communication unit 140 transmits and receives various information and various data to and from the operator device 200, the user device 300, other devices of the external system, and the like via the network N. The communication unit 140 receives, for example, the first history information from the operator device 200 or the information request from the user device 300 via the network N. The communication unit 140 transmits the first history information to the user apparatus 300 via, for example, the network N.

Further, those skilled in the art can adopt an embodiment in which each element described below is replaced with an equal one, and such an embodiment is also included in the scope of the present invention.

[Modification example]
Although the present invention has been described based on the above embodiment, the following cases are also included in the present invention.

(1) At least a part of each configuration included in the information providing devices 100 and 100a according to the above embodiment may be provided in the operator device 200. For example, the functions of the reception unit 113 and the provision unit 115 of the information providing apparatus 100 may be implemented in the operator apparatus 200.

(2) In the above embodiment, an example in which the transfer in which the account of the transfer destination of the first transfer and the account of the transfer source match is defined as the second transfer is described, but the present invention is not limited to this. The transfer may include a first transfer, a second transfer, and a relay transfer performed during a second predetermined period between the account to which the first transfer is transferred and the account from which the second transfer is transferred. Here, the "second predetermined period" means a period between the transfer date and time of each of the first transfer and the second transfer.

The control unit 110 of the information providing devices 100 and 100a may include a relay determination unit (not shown).

The relay determination unit inquires of the third device about the presence or absence of relay transfer, and determines the presence or absence of relay transfer based on the response. The "third device" is a device different from the first device from which the first history information is collected. Specifically, the third device is used by a second business operator different from the first business operator who uses the first device (business operator device 200), or a third business operator who acts as a proxy for collecting the first history information. It is a device to do. Here, the "second business operator" is typically a business operator that does not use the retrieval infrastructure, but the purpose is not limited to this. Further, here, the “third business operator” is a business operator that collects the first history information of the transfer from the first device instead of the retrieval infrastructure.

According to the above configuration, even if the first history information of the relay transfer executed by the third device cannot be collected from the third device, the relay determination unit asks the third device for the presence or absence of the relay transfer, so that the relay transfer can be performed. The first relocation and the second relocation can be connected through.

As another example, the relay determination unit may determine the presence or absence of relay transfer by referring to the storage unit.

When the relay determination unit determines that there is a relay transfer, the recording unit 112 may record the first history information of each of the first transfer, the relay transfer, and the second transfer in the storage unit in association with each other.

When the extraction unit 114 extracts the first history information of any of the first transfer, the relay transfer, and the second transfer, the extraction unit 114 may also extract the other first history information.

According to the above configuration, the extraction unit 114 can extract the first history information of the relay transfer and the second transfer having a certain continuity with the first transfer in addition to the first transfer corresponding to the search key. Therefore, according to the above configuration, the extraction unit 114 enables the user to provide not only the transfer corresponding to the search key but also the transfer consecutive to the transfer by the providing unit 115.

The identification unit 1121 may specify a transfer route connecting the first transfer, the relay transfer, and the second transfer.

If the object is value, for example, at least one of the first transfer, relay transfer or second transfer may include a transfer that transforms the value into a different kind of value.

It is conceivable that the issuer of the value may change from the first business operator to the second event person due to conversion to a different type of value in at least one of the first transfer, relay transfer, or second transfer, and the first history information cannot be collected. Be done. According to the above configuration, even in such a case, the first transfer and the second transfer can be associated with each other via the relay transfer, and these transfers can be extracted together.

(3) In the above embodiment, whether or not there is a certain relationship between a plurality of transfers and whether or not a predetermined condition including that the accounts of the transfer source and the transfer destination match in the second transfer determination unit 117 is satisfied. The example of determination in is described above, but the present invention is not limited to this. For example, a hash value or reference number (hereinafter referred to as "hash value, etc.") is given to the target entered (deposited) in the transfer destination account when the transfer is executed, and this hash value, etc. is used for subsequent transfer. You may show the relevance between multiple relocations by taking over to.

Specifically, the information providing device 100 will be described with reference to the example of FIG. 2, with respect to the deposit amount (in this example, 200 coins) deposited in the user 2 account of A coin in the transfer (a). The hash value (a) is calculated and given.

In the transfer (c), the information providing device 100 also applies a hash value (a) to the value of 10 pays (conversion rate: 1 pay per 20 coins) equivalent to 200 coins deposited in the user 2 accounts of B pay. Give.

As described above, the information providing device 100 assigns the hash value calculated and assigned to the value of the preceding transfer to the value of the succeeding transfer, so that the hash value is between the preceding transfer and the succeeding transfer. Etc. are taken over. The information providing device 100 includes the inherited hash value and the like in the first history information at each transfer, and causes the business operator device 200 to output the inherited hash value and the like. In the above, an example of inheriting the hash value or the like given in the immediately preceding transfer has been described, but as another example, the hash values or the like of all the preceding transfers may be inherited.

"Giving a hash value, etc. to a value" means, for example, recording a hash value, etc. for each unit value (for example, 1 coin, 100 points, etc.) in the total asset amount (account balance) of the value held by the account. It may be to do.

According to this modification, the information providing device 100 performs a plurality of transfers having a certain relationship without determining using a predetermined condition such as whether or not there is a certain relationship between the plurality of transfers. Can be associated.
