Description

Information processing device, information processing method, and program

The present invention relates to an information processing device, an information processing method, and a program.

There is known technology for determining whether a business that has issued an invoice is a qualified invoice registered business (for example, Patent Document 1).

JP 2021-71991 A

In conventional technology, when determining the eligibility of an invoice, the information contained in the received invoice is compared with the information registered in the business database to determine whether the business issuing the invoice is capable of issuing qualified invoices. However, even if a business is registered in the business database at the time the invoice is issued, if the business is not registered at the time of the transaction, it may not be able to issue a qualified invoice for that transaction. Even in such cases, there are cases where the invoice issued by the business is determined to be qualified.

The present invention has been made in consideration of these points, and aims to improve the accuracy of determining the eligibility of transaction documents issued by specified businesses.

The information processing device of the first aspect of the present invention includes a supporting data acquisition unit that acquires supporting data, which is electronic data of transaction documents; a registrant information acquisition unit that acquires registrant information indicating a registration period during which the business that issued the transaction documents is a registered business that is registered as a business that can issue specified documents; a determination unit that determines that there is an abnormality in the supporting data if the time of the transaction covered by the supporting data is not included in the registration period of the business; and an output unit that outputs the determination result made by the determination unit.

The registrant information acquisition unit may acquire the registrant information based on a business number included in the supporting document data, the business number being a business number for identifying the business that issued the transaction document.

The registrant information acquisition unit may acquire the registrant information including a business number for identifying the business that issued the transaction document and a registration date indicating the date on which the business indicated by the business number included in the supporting data was registered as a qualified invoice issuing business, and the determination unit may determine that there is an abnormality in the supporting data if the time of the transaction covered by the supporting data is earlier than the registration date of the business.

The registrant information acquisition unit acquires the registrant information further including the date on which the registration of the business, as a qualified invoice issuing business, indicated by the business number included in the supporting data expired, and the determination unit may determine that there is an abnormality in the supporting data when the time of the transaction covered by the supporting data is the same day as the day on which the business's registration expired or later than the day on which the business's registration expired, regardless of the relationship between the time of the transaction covered by the supporting data and the date of registration of the business.

If the supporting data acquired by the supporting data acquisition unit does not include the business number of the business, the registrant information acquisition unit may acquire the registrant information based on the business name of the business included in the supporting data and location information indicating the location of the business.

The output unit may output a predetermined message when the supporting data acquired by the supporting data acquisition unit does not include the business number of the business, when the registrant information acquisition unit is unable to acquire business information corresponding to the business name and business location information of the business included in the supporting data, or when the registrant information acquisition unit acquires multiple businesses corresponding to the business name and business location information of the business included in the supporting data.

The device may further include a business identification unit that, when the supporting data acquired by the supporting data acquisition unit does not include the business number of the business, identifies the business number of the business based on the business name of the business included in the supporting data and location information indicating the location of the business, and the registrant information acquisition unit may acquire the registrant information based on the business number identified by the business identification unit.

The output unit outputs a predetermined message when the supporting data acquired by the supporting data acquisition unit does not include the business number of the business, and the business identification unit cannot identify the business corresponding to the business name and location information of the business included in the supporting data.

The device may further include a storage unit that stores transaction detail data that associates transaction identification information for identifying a transaction with the time at which the transaction was carried out, and the supporting data acquisition unit acquires the supporting data that further includes multiple different transaction identification information covered by the supporting data, and the determination unit identifies the times of multiple transactions associated in the transaction detail data with each of the multiple transaction identification information included in the supporting data, and may determine that there is an abnormality in the supporting data if any of the identified times of the multiple transactions is not included in the registration period of the business operator.

The supporting data acquisition unit acquires the supporting data including the issue date of the transaction document and the transaction content, and the determination unit may determine that there is an anomaly in the supporting data when the transaction content included in the supporting data is a transaction for which the time of the transaction needs to be recorded and the transaction time included in the supporting data is not included in the registration period of the business operator if the transaction content included in the supporting data is a transaction for which the time of the transaction needs to be recorded and the determination unit may determine that there is an anomaly in the supporting data when the issue date included in the supporting data is not included in the registration period of the business operator if the transaction content included in the supporting data is a transaction for which the time of the transaction does not need to be recorded.

The information processing method of the second aspect of the present invention includes a step executed by a computer to acquire supporting data, which is electronic data of transaction documents; a step to acquire registrant information indicating a registration period during which the business that issued the transaction documents is a registered business registered as a qualified invoice issuing business; a step to determine that there is an abnormality in the supporting data if the time of the transaction covered by the supporting data is not included in the registration period of the business; and a step to output the determination result by the determination unit.

In the program of the third aspect of the present invention, a computer is caused to execute the steps of acquiring supporting data, which is electronic data of transaction documents; acquiring registrant information indicating the registration period during which the business that issued the transaction documents was a registered business registered as a qualified invoice issuing business; determining that there is an anomaly in the supporting data if the time of the transaction covered by the supporting data is not included in the registration period of the business; and outputting the determination result by the determination unit.

The present invention has the effect of improving the accuracy of determining the eligibility of transaction documents issued by a specified business operator.

[Overview of Information Processing System S]
1 is a diagram for explaining an overview of the processing of an information processing system S according to an embodiment. The information processing system S is a system for receiving and processing documents issued by businesses that issue specified documents. An example of a specified document is a transaction document such as an invoice or delivery note issued by a qualified invoice issuing business. The information processing system S has an information processing device 1, an information terminal 2, and a registrant management device 3.

The information processing device 1 is a device for acquiring specified documents issued by other businesses and processing the received documents. The information processing device 1 is a computer used by the business receiving the documents. The information processing device 1 may be a facility of the business receiving the documents, or may be a cloud server used by multiple businesses. The information processing device 1, for example, determines whether the acquired invoice is an invoice issued by a qualified invoice issuing business, and processes the invoice based on the result of the determination.

The information terminal 2 is a terminal used by a user (e.g., an accounting staff member) of the business receiving the invoice, and is, for example, a computer. The information terminal 2 inputs supporting data received from the business that issued the transaction documents (hereinafter also referred to as the "issuing business") into the information processing device 1. The supporting data is data that is the electronic version of the transaction documents. The information terminal 2 displays information indicating the determination result received from the information processing device.

The registrant management device 3 is a device that manages registrant information. The registrant management device 3 is, for example, a server managed by a government office that registers qualified invoice businesses. Registrant information is information that indicates the location, name, and period of registration of a qualified invoice business. The registrant management device 3 accepts additions, changes, deletions, etc. of registrant information from the information terminal 2, etc. In response to a request to obtain registrant information received from the information processing device 1, the registrant management device 3 transmits the registrant information to the device that sent the request.

The processing in the information processing system S will be described with reference to Figures 1 and 2. Figure 2 is a diagram showing an example of a determination process in the information processing device 1. The information processing device 1 acquires supporting evidence data from the information terminal 2 ((1) in Figure 1). The information processing device 1 transmits a request to acquire registrant information to the registrant management device 3 ((2) in Figure 1). The request to acquire registrant information is information for acquiring registrant information about the issuing business.

The information processing device 1 acquires registrant information about the issuing business from the registrant management device 3 ((3) in FIG. 1). The registrant information is information indicating the period during which the business has been registered as a business capable of issuing specified documents (e.g., qualified invoices). The information processing device 1 determines whether there are any anomalies in the supporting document data based on the acquired registrant information ((4) in FIG. 1).

The determination process will be explained using FIG. 2. The information processing device 1 identifies the time of the transaction that is the subject of the invoice data. As an example, if the invoice data includes information indicating the transaction date or the period of the transaction in question, the information processing device 1 identifies the transaction date or period of the transaction included in the invoice data as the time of the transaction. The information processing device 1 determines whether the identified time of the transaction is included in the registration period of the issuing business indicated in the registrant information. The registration period is the period from the registration date on which the business is registered until cancellation or expiration. Note that if the end of the registration period is not specified, the information processing device 1 may determine that the time of determination is the end of the registration period, or may determine that there is no end.

In the example shown in FIG. 2, the time of the identified transaction A is not included in the registration period of the issuer indicated in the acquired registrant information, so the information processing device 1 determines that there is an anomaly in the acquired supporting data for transaction A. The time of the identified transaction B is included in the registration period of the issuer indicated in the acquired registrant information, so the information processing device 1 determines that there is no anomaly in the acquired supporting data for transaction B.

Returning to FIG. 1, the information processing device 1 processes the obtained supporting data in accordance with the judgment result ((5) in FIG. 1). If there is no abnormality in the judgment result, the information processing device 1 makes it possible to carry out subsequent processes such as accounting processing and payment processing based on the supporting data. If there is an abnormality in the judgment result, it does not make it possible to carry out accounting processing, etc.

The information processing device 1 may transmit the processing result to the information terminal 2 ((6) in FIG. 1). If there is no abnormality in the judgment result, the information processing device 1 transmits, as an example, information indicating that the processing of the acquired transaction documents has been completed or that the voucher data has been accepted to the information terminal 2. If there is an abnormality in the judgment result, the information processing device 1 transmits error data indicating that the voucher data cannot be processed to the information terminal 2.

By configuring the information processing system S in this way, it is possible to improve the accuracy of determining the eligibility of transaction documents issued by other businesses.

[Configuration of information processing device 1]
3 is a block diagram showing the configuration of the information processing device 1. The information processing device 1 has a communication unit 11, a storage unit 12, and a control unit 13. The control unit 13 has a voucher data acquisition unit 131, a registrant information acquisition unit 132, a determination unit 133, an output unit 134, and a business entity identification unit 135.

The communication unit 11 is a communication interface for sending and receiving data with other devices via a network. The memory unit 12 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), an SSD (Solid State Drive), a hard disk drive, etc. The memory unit 12 pre-stores programs to be executed by the control unit 13.

The control unit 13 is a processor such as a CPU (Central Processing Unit). The control unit 13 executes the programs stored in the memory unit 12, thereby functioning as a supporting document data acquisition unit 131, a registrant information acquisition unit 132, a determination unit 133, an output unit 134, and a business identification unit 135.

The supporting data acquisition unit 131 acquires supporting data, which is electronic data of transaction documents. Figure 4 is a diagram showing an example of supporting data. The supporting data includes the issue date of the transaction document, information on the business that issued the transaction document, information on the destination business, transaction details, and payment information. The information on the business that issued the transaction document and the information on the destination business include the name, address, business number, and contact information, respectively. The transaction details include information on the traded goods, quantity, amount, tax amount, etc. Payment information is information indicating the payment method, such as the account number of the deposit destination.

The supporting data may further include information indicating the time of the transaction. The information indicating the time of the transaction is, for example, information indicating the transaction date or the transaction period. The transaction date is the date on which the transaction covered by the supporting data was made. The transaction period is information that specifies the period covered by the supporting data, such as "September."

The evidence data may be document data expressed in a data format such as XML. The evidence data may also be image data generated by scanning a paper evidence. In this case, the evidence data acquisition unit 131 performs OCR processing on the acquired image data to identify the meaning and content of the information contained in the evidence data.

The registrant information acquisition unit 132 acquires registrant information indicating the registration period during which the business that issued the transaction documents was a registered business that was registered as a business that can issue specified documents. As an example, the registrant information acquisition unit 132 queries the registrant management device 3 for registrant information.

Figure 5 is a diagram showing an example of the data structure of a registrant information table managed by the registrant management device 3. In the registrant information table, "business number," "business name," "address," "registration date," "cancellation date," and "expiration date" are associated with each other. "Business number" is an ID (Identification) that identifies a business. The business number is, for example, a qualified invoice issuing business registration number or a corporation number. "Business name" and "address" are the name and location of the business indicated by the "business number," respectively. "Registration date" indicates the date on which the business indicated by the "business number" was registered as a qualified invoice issuing business. "Cancellation date" indicates the date on which the registration as a qualified invoice issuing business was cancelled. "Expiration date" indicates the date on which the registration as a qualified invoice issuing business expired.

As an example, the registrant information acquisition unit 132 acquires registrant information based on the business number included in the supporting data. That is, the registrant information acquisition unit 132 queries the registrant management device 3 for registrant information of the business corresponding to the business number of the issuing business included in the supporting data. The registrant management device 3 transmits the registrant information corresponding to the business number of the issuing business to the information processing device 1.

The determination unit 133 determines whether there is an anomaly in the supporting data. The determination unit 133 determines that there is an anomaly in the supporting data if the time of the transaction covered by the supporting data is not included in the registration period of the issuer. As an example, the determination unit 133 determines that there is an anomaly in the supporting data if the result of comparing the transaction date included in the supporting data with the registration period indicated by the registrant information acquisition unit 132 satisfies a predetermined condition.

More specifically, the determination unit 133 compares the transaction date included in the supporting data with the registration date included in the registrant information acquired by the registrant information acquisition unit 132. If the transaction date included in the supporting data is later than the registration date indicated in the registrant information acquired by the registrant information acquisition unit 132, the determination unit 133 determines that the time of the transaction is included in the registration period of the business operator and there is no abnormality in the supporting data. If the transaction date included in the supporting data is earlier than the registration date indicated in the registrant information acquired by the registrant information acquisition unit 132, the determination unit 133 determines that the time of the transaction is not included in the registration period of the issuing business operator and there is an abnormality in the supporting data. Note that if the transaction date included in the supporting data and the registration date indicated in the registrant information acquired by the registrant information acquisition unit 132 are the same day, it determines that there is no abnormality in the supporting data.

If the supporting data includes only information indicating the period of the transaction (e.g., "September"), the determination unit 133, for example, compares the start date of the period of the transaction indicated by the supporting data with the registered period. The determination unit 133 may compare the end date of the period of the transaction with the registered period, or may compare the start date and end date of the period of the transaction with the registered period. Furthermore, if the supporting data does not include either the transaction date or the period of the transaction, but only the issue date of the transaction document, the determination unit 133 may identify the issue date included in the supporting data as the time of the transaction.

The output unit 134 outputs the determination result by the determination unit 133. As an example, the output unit 134 may output the determination result to the information terminal 2. When the determination result by the determination unit 133 indicates that the supporting data was issued by a valid qualified invoice issuer, the output unit 134 may output data for enabling journal entry processing of the transaction indicated by the supporting data or payment processing based on the supporting data to be executed. After executing the journal entry processing or payment processing, the output unit 134 may output the result of the journal entry processing or payment processing.

If the determination result indicates that the supporting data was not issued by a valid qualified invoice issuing business, the output unit 134 may output a determination result indicating that an error has occurred. The output unit 134 may notify the determination result to the contact information stored in the memory unit 12 as the contact information of the destination business of the supporting data.

By configuring the information processing device 1 in this way, it becomes possible to determine that the registrant information is invalid at the time of the transaction, improving the accuracy of determining the eligibility of transaction documents issued by a specified business. As a result, it is possible to prevent a business that receives supporting data from carrying out accounting procedures based on invalid transaction documents.

In the above explanation, an example has been described in which the information processing device 1 queries the registrant management device 3 for registrant information about the issuing business, but the information processing device 1 may be configured to store the registrant information acquired at a predetermined timing (e.g., before the start of business hours on a business day) in the memory unit 12. In this case, the registrant information acquisition unit 132 refers to the memory unit 12 to acquire the registrant information of the issuing business contained in the supporting data acquired by the supporting data acquisition unit 131.

In the above explanation, an example was given of a process for determining whether or not supporting data is valid based on the registration date included in the registrant information, but registration may be cancelled or expired after registration. Therefore, the information processing device 1 may be configured to output an abnormality for transactions after registration has been cancelled or expired.

In order to be able to determine that supporting data from a business whose registration has expired is not valid, the registrant information acquisition unit 132 acquires registrant information that further includes the date on which the registration of the business indicated by the business number included in the supporting data as a qualified invoice issuing business expired. Specifically, the registrant information acquisition unit 132 acquires from the registrant management device 3 registrant information that includes the "expiration date" or "cancellation date" of the business that corresponds to the business number of the issuing business included in the supporting data.

If the time of the transaction covered by the supporting data is after the date on which the business operator's registration expired, the determination unit 133 determines that there is an abnormality in the supporting data, regardless of the relationship between the time of the transaction covered by the supporting data and the business operator's registration date. FIG. 6 is a diagram explaining the determination process of the determination unit 133 in this case. If the acquired registrant information has an expiration date or cancellation date, the registration period is between the registration date and the expiration date. The determination unit 133 determines that there is no abnormality in transaction A because the transaction date of the transaction covered by the supporting data is after the registration date and before the expiration date. The determination unit 133 determines that there is an abnormality in transaction B because the transaction date of the transaction covered by the supporting data is after the expiration date. Note that if the time of the transaction is specified by a period, the determination unit 133 compares the end date of the transaction period with the expiration date or cancellation date. In addition, when the transaction date of the transaction covered by the supporting data is the same as the date on which the business operator's registration expired (the expiration date or cancellation date), the determination unit 133 may determine that there is an abnormality in the supporting data, regardless of the relationship between the time of the transaction covered by the supporting data and the business operator's registration date.

Note that if the supporting data does not include the business number of the issuing business, the registrant information may be acquired based on other information that is included in the supporting data and that indicates the issuing business. Specifically, if the supporting data acquired by the supporting data acquisition unit 131 does not include the business number of the issuing business, the registrant information acquisition unit 132 acquires the registrant information based on the business name and location of the issuing business that are included in the supporting data. That is, the registrant information acquisition unit 132 queries the registrant management device 3 for registrant information that corresponds to the business name and location of the issuing business that are included in the supporting data. Note that the registrant information acquisition unit 132 may acquire the registrant information based on a contact telephone number and payee information instead of or in addition to the location and name.

Furthermore, when acquiring registrant information based on information other than the business number, there may be cases where corresponding registrant information cannot be acquired, or where the registrant information of the issuing business cannot be identified by acquiring multiple corresponding registrant information. Therefore, the output unit 134 may output a predetermined message when the business number of the business is not included in the evidence data acquired by the evidence data acquisition unit 131 and the registrant information cannot be identified. The registrant information cannot be identified when the registrant information acquisition unit 132 cannot acquire registrant information corresponding to the business name and business location information of the business included in the evidence data, or when the registrant information acquisition unit 132 acquires multiple businesses corresponding to the business name and business location information of the business included in the evidence data. The predetermined message is, for example, information indicating that the registrant information cannot be identified because there is no registrant information or there is multiple registrant information.

When multiple pieces of registrant information corresponding to the name and location of the issuing business are acquired, the output unit 134 may display on the information terminal 2 a screen that prompts the user to select from the multiple pieces of registrant information acquired. Then, when the user does not select any registrant information or an operation is performed indicating that no information corresponding to the issuing business exists in the displayed registrant information, the output unit 134 may determine that the issuing business cannot be identified and output a specified message.

[Identifying business operator number]
An example of acquiring registrant information based on the business number of the issuing business has been described. If the business number of the issuing business is not included in the supporting data, the information processing device 1 may be configured to identify the business number based on other information included in the supporting data, and to identify the registrant information based on the identified business number.

In this case, the memory unit 12 may store a business information table for identifying the business number. Figure 7 is a diagram showing an example of the data structure of a business information table. In the business information table shown in Figure 7, "business number," "business name," "address," "telephone number," and "payee account number" are associated with each other. As an example, the business information table stored in the memory unit 12 is information on businesses that have issued invoices that have been previously processed by the information processing device 1.

The device further includes a business identification unit 135 that, when the supporting data acquired by the supporting data acquisition unit 131 does not include the business number of the issuing business, identifies the business number of the issuing business based on the business name of the issuing business included in the supporting data and the location information indicating the location of the issuing business. The business identification unit 135 refers to the business information table stored in the memory unit 12 and identifies the business number corresponding to the address and name of the issuer included in the supporting data. The registrant information acquisition unit 132 acquires registrant information based on the business number identified by the business identification unit 135. Note that the business identification unit 135 may identify the business number based on information such as the telephone number and payee account number included in the supporting data instead of or in addition to the address and name of the issuer included in the supporting data.

The output unit 134 may output a predetermined message when the business identification unit 135 cannot identify the business number based on the issuer's address and name. A case in which the business number cannot be identified based on the address and name occurs, for example, when the business number corresponding to the issuer's address and name is not registered in the business information table or when multiple business numbers are registered. The predetermined message is a message indicating that the business number cannot be identified based on the issuer's address and name.

The business identification unit 135 may also identify the business number by inquiring of an external device (not shown) that manages information about business operators about the business number that corresponds to the address and name of the issuing business operator included in the supporting document data.

[Identifying the time of transaction]
In some cases, a single piece of evidence data is used to process a plurality of related transactions. In such cases, the information processing device 1 may be configured to identify the time of the transaction related to the obtained evidence data.

The memory unit 12 stores transaction detail data that associates transaction identification information (also called transaction ID) for identifying a transaction with the time when the transaction was performed. The transaction detail data shows the details of an individual transaction in a series of transactions consisting of multiple transactions.

FIG. 8 is a diagram showing an example of the data structure of transaction detail data stored in the storage unit 12. In the transaction detail data, "transaction ID", "issuer", "destination", "transaction date", "product", "quantity", "amount", and "consumption tax" are associated with each other. "Transaction ID" is an ID for identifying a transaction, such as a voucher ID attached to the transaction detail. "Issuer" and "destination" indicate the business entity that issues and the destination of the transaction detail, respectively. "Transaction date" is the transaction date of the transaction that the transaction detail data covers. In the transaction detail data, the issue date of the transaction detail data or the period of the transaction may be associated instead of or in addition to the "transaction date". "Product" indicates the content or type of product traded in the transaction indicated by the transaction detail data. "Quantity" indicates the quantity of the product traded. "Amount" and "consumption tax" indicate the transaction amount and the consumption tax to be levied, respectively.

When one piece of supporting data corresponds to multiple transactions, the supporting data includes a transaction ID, which is transaction identification information indicating multiple transaction details that are the subject of the claim, etc. In this case, the supporting data acquisition unit 131 acquires supporting data that includes multiple different transaction IDs that are the subject of the supporting data.

The determination unit 133 identifies the times of multiple transactions associated in the transaction detail data with each of the multiple transaction IDs included in the supporting data, and determines that there is an abnormality in the supporting data if any of the identified times of the multiple transactions is not included in the business operator's registration period. The determination unit 133 acquires transaction detail data corresponding to the multiple transaction IDs included in the supporting data acquired by the supporting data acquisition unit 131, and identifies the times of the multiple transactions. For example, the determination unit 133 identifies the transaction dates included in the acquired transaction detail data as the transaction times. The determination unit 133 then compares the identified times of the multiple transactions with the registration period indicated by the registrant information acquired by the registrant information acquisition unit 132. If any of the transaction times indicated in the acquired transaction detail data is not included in the registration period, the determination unit 133 determines that there is an abnormality in the acquired supporting data.

Depending on the content of the transaction, it may not be necessary to state the time of the transaction on the evidence. Therefore, the information processing device 1 may be configured to determine whether or not to specify the time of the transaction depending on the content of the transaction.

In this case, the storage unit 12 may store a table that associates the content of the transaction with whether or not it is necessary to record the time of the transaction. For example, if the transaction is the sale of a product or the fee for using a transportation service such as a taxi, it is not necessary to record the time of the transaction, and if the content of the transaction is the delivery of software, a table indicating that it is necessary to record the transaction date is stored in the storage unit 12.

The supporting data acquisition unit 131 acquires supporting data including the issue date of the transaction document and the contents of the transaction. The contents of the transaction are, for example, information indicating the goods sold, the services provided, or the deliverables or the contract that is the basis of the transaction.

When the content of the transaction included in the supporting data is one for which the time of the transaction needs to be recorded, the determination unit 133 compares the time of the transaction included in the supporting data with the registration period indicated by the acquired registrant information. The determination unit 133 then determines that there is an anomaly in the supporting data when the time of the transaction included in the supporting data is not included in the business operator's registration period. In addition, the determination unit 133 determines that there is an anomaly in the supporting data when the content of the transaction included in the supporting data is one for which the time of the transaction needs to be recorded but the supporting data does not include information indicating the time of the transaction.

If the content of the transaction included in the supporting data is a transaction for which the time of the transaction does not need to be stated, the determination unit 133 takes the issue date of the supporting data included in the supporting data as the time of the transaction and compares it with the registration period indicated by the acquired registrant information. If the issue date included in the supporting data is included in the registration period of the issuer, the determination unit 133 determines that there is no abnormality in the supporting data. If the issue date included in the supporting data is not included in the registration period of the issuer, the determination unit 133 determines that there is an abnormality in the supporting data.

[Processing flow in information processing device 1]
Fig. 9 is a flowchart showing the flow of processing in the information processing device 1. The flowchart shown in Fig. 9 starts from the point when the information processing device 1 acquires evidence data.

The supporting data acquisition unit 131 acquires supporting data (S01). The registrant information acquisition unit 132 determines whether the supporting data acquired by the supporting data acquisition unit 131 includes the business number of the issuing business (S02).

If the supporting data acquired by the supporting data acquisition unit 131 does not include the business number of the issuing business (NO in S02), the registrant information acquisition unit 132 acquires registrant information based on the name and location of the issuing business included in the supporting data (S03). The registrant information acquisition unit 132 determines whether the issuing business has been identified (S04).

If the registrant information can be identified (YES in S04), the information processing device 1 proceeds to S07. If the registrant information cannot be identified (NO in S04), the output unit 134 causes the information terminal 2 to output an error (S05), and the process ends.

If the supporting data acquired by the supporting data acquisition unit 131 includes the business number of the issuing business (YES in S02), the registrant information acquisition unit 132 acquires the registrant information based on the business number of the issuing business (S06). The determination unit 133 compares the time of the transaction covered by the supporting data with the registration period indicated by the acquired registrant information, and determines whether there is an abnormality in the supporting data (S07).

If there is an abnormality in the supporting data (YES in S07), the output unit 134 does not process the supporting data and outputs a processing result indicating the abnormality (S09). If there is no abnormality in the supporting data (NO in S07), the output unit 134 processes the supporting data (S08) and outputs a processing result indicating that the supporting data has been processed normally (S09).
