Description

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

In recent years, there has been an increase in fraudulent bank transfers via mobile phones and ATMs (Automated Teller Machines). A bank transfer system has been disclosed to protect customers from fraudulent bank transfers (see Patent Document 1).

JP 2011-108068 A

The transfer system described in Patent Document 1 allows the customer to select a transfer method. Specifically, the transfer system displays a screen on the display unit that allows the customer to select between a normal transfer process that immediately transfers based on the transfer destination information and a transfer process for preventing transfer fraud based on the transfer destination information. Next, when the transfer process for preventing transfer fraud is selected by the customer, the transfer system starts a diagnosis of whether there is a suspicion of transfer fraud based on preset conditions. In the diagnosis, questions are output to the customer. The transfer system diagnoses whether the transfer is suspected of being a transfer fraud based on the customer's answers to the questions. The transfer system displays the diagnosis results on the display unit and provides the diagnosis results to the customer. This allows the transfer system to avoid transfer fraud against customers. However, the transfer system described in Patent Document 1 relies only on the customer's own judgment without any objective judgment, and therefore cannot adequately prevent transfer fraud.

===Overview of the Configuration of Fraud Prevention System 1===

The fraud prevention system 1 is a system that prevents remittances by fraudulent means by remittances by remittance senders. For example, when a remittance is applied for by a remittance, the fraud prevention system 1 transmits the details of the remittance procedure of the remittance sender to a verifier. The fraud prevention system 1 executes or rejects the remittance procedure of the remittance sender depending on the result of the verifier's confirmation of the details of the remittance procedure. In this way, the fraud prevention system 1 can prevent damage from fraud because a third party can be confirmed when the remittance sender remits money. Here, remittance refers to the act of moving money from the remittance sender to a specified person, and may include, for example, a transfer in which money is moved from the remittance sender's bank account to the specified person's bank account. The remittance sender is, for example, a person who remits money to a specified person via a mobile terminal (for example, a smartphone) or an ATM. The verifier is, for example, a person preset in the fraud prevention system 1, such as a relative or friend of the remittance sender.

First, the configuration of the fraud prevention system 1 will be described with reference to FIG. 1. FIG. 1 is a diagram showing an example of the configuration of the fraud prevention system 1. As shown in FIG. 1, the fraud prevention system 1 includes, for example, a financial institution system 10, a fraud determination server 20, a verifier terminal device 30, and a remittance terminal device 40. In the fraud prevention system 1, the functions of a certain component may be possessed by other components. For example, the fraud determination server 20 may have all or part of the functions of the financial institution system 10. In the fraud prevention system 1, the financial institution system 10, the fraud determination server 20, the verifier terminal device 30, and the remittance terminal device 40 are each connected to be able to communicate with each other via a network 50. Each component of the fraud prevention system 1 will be described below.

The financial institution system 10 is a system that accepts remittance procedure requests from remitters. Specifically, the financial institution system 10 obtains information related to the remittance procedure request from the remittance terminal device 40 (hereinafter referred to as "remittance request information"). The remittance request information may include, for example, the remitter's account name, the remitter's account number, the remittance recipient's name, the remittance recipient's account number, and information related to the remittance amount. The financial institution system 10 is composed of, for example, an information processing device such as a server computer. The financial institution system 10 may also include an ATM. The financial institution system 10 is connected to the fraud determination server 20 via the network 50, and transmits and receives various information to and from the fraud determination server 20.

The fraud determination server 20 obtains remittance request information from the financial institution system 10. For example, based on the remittance request information, the fraud determination server 20 determines whether to send information for requesting the verifier to confirm whether or not to permit the remittance procedure of the remitter (hereinafter referred to as "confirmation request information") to the verifier's terminal device 30. The fraud determination server 20 then obtains information on the result of the confirmation by the verifier from the verifier's terminal device 30 (hereinafter referred to as "confirmation result information"). Furthermore, based on the confirmation result information, the fraud determination server 20 transmits information on whether or not to permit the remitter to carry out the remittance procedure of the remitter (hereinafter referred to as "remittance approval/disapproval information") to the financial institution system 10. Note that, in the following, information of the confirmation result information indicating that the verifier has approved the remittance procedure of the remitter will be described as "approval result information" and information indicating that the verifier has rejected the remittance procedure of the remitter will be described as "rejection result information". Additionally, among the remittance approval/disapproval information, information that causes the financial institution system 10 to execute the remittance procedure of the remitter is described as "remittance execution information," and information that causes the financial institution system 10 to reject the remitter's remittance procedure is described as "remittance rejection information."

The terminal device 30 is a terminal held by the verifier. The terminal device 30 is, for example, a smartphone, a notebook computer, or a desktop computer. The terminal device 30 transmits and receives various information to and from the fraud determination server 20 via the network 50. The terminal device 30 accepts operational input from the verifier by displaying various information on the display device 107 (see FIG. 15). Note that multiple terminal devices 30 may be included. In other words, the fraud prevention system 1 may be configured to obtain verification result information for the remitter's remittance procedure from multiple terminal devices 30.

The terminal device 40 is, for example, a mobile terminal of the remitter or an ATM of a financial institution. The terminal device 40 transmits and receives various information between the financial institution system 10 and the fraud determination server 20 via the network 50.
===Outline of Processing of Fraud Prevention System 1===

The process of the fraud prevention system 1 will be outlined with reference to FIG. 2. FIG. 2 is a diagram showing an outline of the process of the fraud prevention system 1. As an example, FIG. 2 explains an outline of the process from when a remitter applies for a remittance procedure to when a verifier rejects the remitter's remittance procedure.

First, in step S10, the remittance terminal device 40 generates remittance request information in response to operational input by the remitter. The remittance terminal device 40 transmits the remittance request information to the fraud determination server 20.

Next, in step S11, the financial institution system 10 acquires remittance request information. The financial institution system 10 identifies the remitter from the remittance request information. In step S12, the financial institution system 10 determines whether the identified remitter is a person who requires the permission of a verifier, for example by referring to a specified data table. If the financial institution system 10 determines that the remitter is not a person who requires the permission of a verifier (step S12: NO), it executes the remittance procedure for the remitter (step S17). If the financial institution system 10 determines that the remitter is a person who requires the permission of a verifier (step S12: YES), it transmits the remittance request information to the fraud determination server 20.

Next, in step S13, the fraud determination server 20 acquires remittance request information. Based on the remittance request information, the fraud determination server 20 determines whether the remitter meets certain conditions. The certain conditions are described below. If the fraud determination server 20 determines that the remitter does not meet the certain conditions (step S13: not met), it sends remittance execution information to the financial institution system 10. In this case, in step S17, the financial institution system 10 executes the remittance procedure for the remitter. If the fraud determination server 20 determines that the remitter meets the certain conditions (step S13: met), it sends confirmation request information to the confirmer's terminal device 30 (step S14).

Next, in step S15, the terminal device 30 displays a screen regarding the confirmation request (hereinafter referred to as the "confirmation request screen") on the display device 107 based on the confirmation request information. The confirmation request screen will be described later. The terminal device 30 acquires confirmation result information in response to operational input by the person making the check on the confirmation request screen. The terminal device 30 transmits the confirmation result information to the fraud determination server 20.

Next, in step S16, for example, if the fraud determination server 20 obtains rejection result information indicating that the remittance procedure is rejected, it may send remittance rejection information indicating that the remittance procedure of the remitter is rejected to the financial institution system 10. In this case, in step S18, the financial institution system 10 rejects the remitter's remittance procedure. Note that in step S16, for example, if the fraud determination server 20 obtains permission decision information indicating that the remittance procedure is permitted, it may send remittance permission information indicating that the remittance procedure of the remitter is permitted to the financial institution system 10. In this case, in step S18, the financial institution system 10 executes the remittance procedure of the remitter.
Functional Configuration of Fraud Prevention System 1

Next, the functions of the financial institution system 10, the fraud determination server 20, the verifying person's terminal device 30, and the remittance terminal device 40 in the fraud prevention system 1 will be described.
<<Financial institution system 10>>

First, the functional configuration of the financial institution system 10 will be described with reference to FIG. 3. FIG. 3 is a diagram showing an example of the functional configuration of the financial institution system 10. As shown in FIG. 3, the financial institution system 10 has the functions of a memory unit 11, a transmission/reception unit 12, a determination unit 13, and a remittance execution unit 14. Each function is realized by the processor 101 shown in FIG. 15 reading and executing a computer program stored in the memory unit 103, and controlling each component of the financial institution system 10.

The storage unit 11 may include, for example, subject information 11a. The subject information 11a stores data on subjects who are remitters and need to obtain permission from a verifier to remit money. FIG. 4 is a diagram showing an example of the data structure of the subject information 11a. As shown in FIG. 4, the data structure of the subject information 11a is, for example, a collection of records including data such as an account number and account name, with an appropriate item such as the subject ID as a primary key. The contents of the subject information 11a are set in the financial institution system 10 at the request of the verifier. The subject ID is an identification code that identifies a subject who needs to obtain permission from a verifier. The account number is the account number of the subject. The account name is the account name of the subject.

The transmitter/receiver unit 12 transmits and receives various information between the remittance terminal device 40, the verifying terminal device 30, and the fraud determination server 20.

The determination unit 13 refers to the target person information 11a to determine whether the remitter is a target person. Specifically, the determination unit 13 compares, for example, the account number and account name of the remitter included in the remittance request information with the account number and account name entered in the target person information 11a, and if they match, determines that the remitter is a target person.

The remittance execution unit 14 executes the remittance procedure of the remitter, for example, when the determination unit 13 determines that the remitter is not an eligible person. The remittance execution unit 14 may also execute the remittance procedure of the remitter, for example, when it acquires remittance execution information from the fraud determination server 20. The remittance execution unit 14 may also reject the remittance procedure of the remitter, for example, when it acquires remittance rejection information from the fraud determination server 20.
<<Fraud Determination Server 20>>

Next, the functional configuration of the fraud determination server 20 will be described with reference to FIG. 5. FIG. 5 is a diagram showing an example of the functional configuration of the fraud determination server 20. As shown in FIG. 5, the fraud determination server 20 has the functions of a memory unit 21, an acquisition unit 22, a condition determination unit 23, a confirmation unit 24, a display control unit 25, and a remittance processing unit 26. Each function is realized by the processor 101 shown in FIG. 15 reading and executing a computer program stored in the memory device 103, and controlling each component of the fraud determination server 20.

The memory unit 21 has, for example, remitter information 21a, verifyer information 21b, and screen information 21c. The data structures of remitter information 21a, verifyer information 21b, and screen information 21c will be described with reference to Figures 6, 7, and 8. Figure 6 is a diagram showing an example of the data structure of remitter information 21a. Figure 7 is a diagram showing an example of the data structure of verifyer information 21b. Figure 8 is a diagram showing an example of the data structure of screen information 21c.

The remitter information 21a stores data on the remitter who is confirmed by the verifier. As shown in FIG. 6, the data structure of the remitter information 21a is, for example, a collection of records containing data such as the target ID, the verifier ID, and remittance history, with an appropriate item such as the remitter ID as the primary key. The contents of the remitter information 21a may be set in the fraud determination server 20, for example, at the request of the verifier. The remitter ID is an identification code that identifies the remitter. The target ID corresponds to the target ID in the target information 11a. The verifier ID is an identification code that identifies the verifier who confirms the remittance procedure of the remitter. Note that when multiple verifiers are used for confirmation, multiple verifier IDs may be associated with one remitter ID. The remittance history is information on the name and account number of the remittance destination to which the remitter has previously sent remittance. The remittance history may be information obtained from the financial institution system 10, for example, through an API (Application Programming Interface).

The verifier information 21b stores data related to the verifier. As shown in FIG. 7, the data structure of the verifier information 21b is, for example, a collection of records containing data such as a device ID, email address, and telephone number, with an appropriate item such as the verifier ID as the primary key. The contents of the verifier information 21b are set in the fraud determination server 20 at the request of the verifier. The verifier ID is an identification code corresponding to the verifier ID in the remitter information 21a. The device ID is an identification code that identifies the verifier's terminal device 30. The email address is an email address held by the verifier. The telephone number is a telephone number set in the verifier's terminal device 30.

Screen information 21c stores information about various screens to be displayed on the display device 107 of the verifyer's terminal device 30. The various screens will be described later. As shown in FIG. 8, the data structure of screen information 21c is, for example, a collection of records containing screen data, with an appropriate item such as a screen ID as the primary key. The screen ID is an identification code that identifies the screen. The screen data is information about the screen to be displayed on the display device 107 of the verifyer's terminal device 30.

The acquisition unit 22 acquires various information from the remittance terminal device 40, the verifying party's terminal device 30, and the fraud determination server 20.

The condition determination unit 23 determines whether the remitter satisfies certain conditions based on the remittance request information obtained from the financial institution system 10. The details of the processing of the condition determination unit 23 are explained below.

The condition determination unit 23 may, for example, determine whether the remittance destination is the first remittance destination to which the remitter has remitted money based on the remittance request information (hereinafter referred to as the "first determination process"). That is, the condition determination unit 23 determines that confirmation by a verifying person is required when the remitter remits money to a party to which the remitter has not remitted money before. Specifically, the condition determination unit 23 compares information on the name and account number of the remittance destination in the remittance request information with information on the name and account number of the remittance destination in the remitter information 21a. If the condition determination unit 23 determines that the remittance destination is a remittance destination to which the remitter has remitted money in the past as a result of the comparison, it determines that the predetermined condition is not satisfied. On the other hand, if the condition determination unit 23 determines that the remittance destination is a remittance destination to which the remitter has not remitted money in the past as a result of the comparison, it determines that the predetermined condition is satisfied. In this way, the fraud determination server 20 can appropriately determine remittance procedures that are likely to be fraudulent by grasping the characteristic that in fraud, the remittance destination is often a first remittance destination.

The condition determination unit 23 may also determine whether the remittance amount by the remitter is equal to or greater than a predetermined amount, for example, based on the remittance request information (hereinafter referred to as the "second determination process"). That is, the condition determination unit 23 determines that when the remitter remits an amount that the remitter would not normally remit, it is necessary to obtain the verifier's permission. Specifically, the condition determination unit 23 identifies information related to the remittance amount in the remittance request information. The condition determination unit 23 compares the remittance amount with a preset amount. If the condition determination unit 23 determines that the remittance amount is smaller than the preset amount as a result of the comparison, it determines that the predetermined condition is not satisfied. On the other hand, if the condition determination unit 23 determines that the remittance amount is equal to or greater than the preset amount as a result of the comparison, it determines that the predetermined condition is satisfied. In this way, the fraud determination server 20 can properly determine which remittance procedures are likely to be fraudulent, based on the characteristic that fraud often involves large remittance amounts.

The condition determination unit 23 may also determine, for example, based on the number comparison information, whether or not the telephone number to which the remitter received a call within a predetermined period is included in the telephone numbers registered by the remitter (hereinafter referred to as the "third determination process"). That is, the condition determination unit 23 determines that the remitter needs to obtain the permission of the verifier when the terminal device 40 receives a call from a telephone number unknown to the remitter within a predetermined period from the time of the remittance procedure. The number comparison information is information on the result of a comparison between the registered number information and the called number information in the terminal device 40. Here, the registered number information is, for example, information on a telephone number registered in the terminal device 40. Also, the called number information is, for example, information on a telephone number to which the terminal device 40 received a call. The number comparison information may be, for example, information acquired by an application installed in the terminal device 40. The number comparison information may be, for example, information included in the confirmation request information. Also, the number comparison information may include information on the time when the call was received from a telephone number unknown to the remitter (hereinafter referred to as "time information"). The condition determination unit 23 may determine, for example, based on the time information, whether or not the call is within a predetermined period. The condition determination unit 23 may also determine whether or not the call is within a predetermined period based on time information about the time when the number comparison information was acquired. This allows the fraud determination server 20 to properly determine which remittance procedures are likely to be fraudulent, based on the characteristic that fraud often involves calls from phone numbers that are not registered in the phone book.

In addition to the third judgment process, the condition judgment unit 23 may also judge whether the remitter responded to a telephone number that is not registered based on the response history information (hereinafter referred to as the "fourth judgment process"). The response history information is, for example, information on the response records to telephone numbers to which the remitter has received calls. The response history information may be, for example, information acquired by an application installed in the terminal device 40. The response history information may be, for example, information included in the confirmation request information. That is, if the remitter receives a call from a telephone number that the remitter does not know and the remitter responds to the call, the condition judgment unit 23 judges that it is necessary to obtain the permission of the verifier. In this way, the fraud judgment server 20 can appropriately determine which remittance procedures are likely to be fraudulent by capturing the characteristic that in fraud cases, calls are made from telephone numbers that are not registered in the telephone book and that the remitter often responds to the call.

The condition determination unit 23 may make a determination by any combination of the first, second, third, and fourth determination processes described above. Specifically, as an example, the condition determination unit 23 may determine, based on the remittance request information, whether the remittance destination is a remittance destination to which the sender is making a remittance for the first time (first determination process), and determine whether the remittance amount by the remittance sender is equal to or exceeds a predetermined amount (second determination process). In this case, when the condition determination unit 23 determines that the remittance destination is a remittance destination to which the sender has not previously sent remittances and determines that the remittance amount is equal to or exceeds a predetermined amount, it determines that the predetermined condition is satisfied. As an example, the condition determination unit 23 may determine whether the remittance destination is the first remittance destination for the remitter based on the remittance request information (first determination process), determine whether the remittance amount by the remitter is equal to or greater than a predetermined amount (second determination process), and determine whether the telephone number to which the remitter has received a call within a predetermined period is included in the telephone numbers registered by the remitter based on the number comparison information (third determination process). In this case, the condition determination unit 23 determines that the remittance destination is a remittance destination to which the remitter has not previously received a remittance, determines that the remittance amount is equal to or greater than a preset amount, and determines that the telephone number to which the remitter has received a call within a predetermined period is not included in the registered telephone numbers, and determines that the predetermined condition is satisfied. In this way, the fraud determination server 20 can appropriately distinguish frauds of various types by combining various determination processes, and therefore can appropriately distinguish remittance procedures that are likely to be fraudulent. Note that, for example, when the terminal device 40 is an ATM, the condition determination unit 23 may combine the first determination process and the second determination process.

When the condition determination unit 23 determines that the predetermined conditions are met, the confirmation unit 24 refers to the remitter information 21a and sends confirmation request information to the confirmer linked to the remitter.

The display control unit 25 generates information regarding various screens to be displayed on the display device 107 of the terminal device 30 and the terminal device 40. Below, an example of a screen generated by the display control unit 25 will be described with reference to Figures 9, 10, and 11. Figure 9 is a diagram showing an example of a confirmation request screen T1. Figure 10 is a diagram showing another example of a confirmation request screen T2. Figure 11 is a diagram showing an example of a result notification screen T3.

As shown in FIG. 9, the display control unit 25 may generate information regarding a confirmation request screen T1 to be displayed on the display device 107 of the confirming person's terminal device 30. Specifically, the confirmation request screen T1 may include, for example, a remitter T11, a remittance account number T12, a remittance account name T13, a remittance amount T14, a confirmation reason T15, a reject button T16, and an allow button T17. The remitter T12 is, for example, an area where the account name (name) of the remitter is displayed. The remittance account number T12 is, for example, an area where the remittance account number of the remittance destination is displayed. The remittance account name T13 is, for example, an area where the remittance destination account name is displayed. The remittance amount T14 is, for example, an area where the amount remitted by the remitter to the remittance destination is displayed. The confirmation reason T15 is, for example, an area where the content determined to satisfy a predetermined condition by the condition determination unit 23 is displayed. By displaying the verification reason T15, the verifier can properly grasp the situation of the remitter, allowing the verifier to make a quick decision. The reject button T16 is a button for sending rejection result information to the fraud determination server 20 when operational input from the verifier is accepted. The allow button T17 is a button for sending approval result information to the fraud determination server 20 when operational input from the verifier is accepted.

As shown in FIG. 10, the display control unit 25 may generate information about a confirmation request screen T2 to be displayed on the display device 107 of the terminal device 30 of the confirmer. The confirmation request screen T2 is a screen that identifiably displays the confirmation statuses of multiple confirmers. Specifically, the confirmation request screen T2 includes, for example, a confirmation status T28 in addition to the components of the confirmation request screen T1. The confirmation status T28 is an area that displays the confirmation status of each confirmer when, for example, confirmation request information is sent to multiple confirmers. Note that the confirmation information T28 may display the confirmation status of at least one of the multiple confirmers. The confirmation status T28 may include, for example, a name T281 and a status T282. The name T281 is an area that displays the name of the confirmer. The status T282 is an area that displays the permission status. This allows the confirmer to know whether the other confirmers have approved or rejected the request, and also to know which confirmers have already confirmed the request, so that the confirmer who has understood this can make a more appropriate decision.

As shown in FIG. 11, the display control unit 25 may generate information about the result notification screen T3 to be displayed on the display device 107 of the remitter's terminal device 40 (here, for example, a smartphone). The fraud determination server 20 transmits information about the result notification screen T3 to the terminal device 40, for example, after confirmation by the verifier. The result notification screen T3 is a screen that displays the confirmation result of the verifier. Specifically, the result notification screen T3 may include, for example, a remittance result T31, a verifier T32, and a verifier contact button T33. The remittance result T31 is an area that displays, for example, the result of approval or rejection of the remittance procedure. The verifier T32 is an area that displays, for example, the name of the verifier who confirmed the remittance procedure. The verifier contact button T33 is, for example, a button for contacting the verifier who confirmed the remittance procedure. The verifier contact button T33 may be a button for causing the processor 101 of the terminal device 40 to execute a process of contacting the verifier's telephone number or a process of transitioning to an email sending screen when an operational input from the remitter is received. By displaying the confirmation request screen T2, the remitter can know whether the remittance procedure has been carried out or rejected, and can quickly confirm with the verifier if it has been rejected, thereby preventing the remitter from committing future fraudulent remittance procedures.

The remittance processing unit 26 transmits remittance permission information (remittance execution information or remittance rejection information) to the financial institution system 10 based on the confirmation result information acquired from the terminal device 30 of the verifier. Specifically, for example, when the remittance processing unit 26 acquires permission result information from the terminal device 30 of the verifier, the remittance processing unit 26 may transmit remittance execution information to the financial institution system 10. Also, for example, when the remittance processing unit 26 acquires confirmation result information from the terminal devices 30 of multiple verifiers, if all of the confirmation result information is permission result information, the remittance processing unit 26 may transmit remittance execution information to the financial institution system 10. Also, when the remittance processing unit 26 acquires confirmation result information from the terminal devices 30 of multiple verifiers, if it acquires permission result information from at least one of the terminal devices 30, the remittance processing unit 26 may transmit remittance execution information to the financial institution system 10. Also, when the remittance processing unit 26 acquires confirmation result information from the terminal devices 30 of multiple verifiers, if it acquires rejection result information from at least one of the terminal devices 30, the remittance processing unit 26 may transmit remittance rejection information to the financial institution system 10. As a result, the financial institution system 10 executes processing for the remitter's remittance procedure according to the remittance approval information.
<<Terminal Devices 30, 40>>

Next, the functional configuration of the terminal device 30 will be described with reference to FIG. 12. The terminal device 40 has the same configuration as the terminal device 30, and the description thereof will be omitted. FIG. 12 is a diagram showing an example of the functional configuration of the terminal device 30. As shown in FIG. 12, the terminal device 30 has the functions of an input unit 31, a transmission/reception unit 32, a display control unit 33, and an information generation unit 34. The functions of the terminal device 30 are realized by the processor 101 shown in FIG. 15 reading and executing a computer program stored in the storage device 103, and controlling each configuration of the terminal device 30. The input unit 41 accepts input of various data in response to, for example, an operation input by a verifyer to the terminal device 30. The transmission/reception unit 42 transmits and receives various information between the terminal device 30 and other devices. The display control unit 33 displays a screen acquired from the fraud determination server 20 on the display device 107. The information generation unit 34 transmits, for example, number comparison information regarding the result of comparing the registration number information and the incoming number information to the fraud determination server 20.
===Processing Procedure of Fraud Prevention System 1===

Next, the processing procedure of the fraud prevention system 1 will be described with reference to FIG. 13. FIG. 13 is a flow diagram showing an example of the processing of the fraud prevention system 1. Note that FIG. 13 shows, as an example, the processing procedure from when the fraud determination server 20 acquires remittance request information from the remittance terminal device 40 to when the fraud determination server 20 transmits remittance approval/disapproval information to the financial institution system 10.

In the following, as an example, terminal device 30 and terminal device 40 are described as smartphones, the sender is Sender A, the remittance destination is Remittance Destination B, and the verifiers are Verifier C, Verifier D, and Verifier E.

In the following, as an example, the remittance request information will be described as including, for example, the account name A of remitter A, the account number 01234 of remitter A, the account name B of remittance destination B, the account number 12345 of remittance destination B, information relating to the remittance amount of 2,000,000 yen, number comparison information (here, "information indicating that the numbers do not match"), and response history information (here, "information indicating that a response has been made").

In the following, as an example, the fraud determination server 20 is described as sending confirmation request information to the verifyer when all of the conditions in the first determination process, the second determination process, the third determination process, and the fourth determination process are met. However, the fraud prevention system 1 may also send confirmation request information to the verifyer when the conditions in at least one of the first determination process, the second determination process, the third determination process, and the fourth determination process are met.

First, in step S100, the fraud determination server 20 acquires remittance request information from the financial institution system 10.

Next, in step S101, the fraud detection server 20 executes a first determination process based on the remittance request information. As a specific example, the fraud detection server 20 compares the remittance destination account number 12345 included in the remittance request information with the remittance destination account numbers to which the remitter has previously remitted, obtained from the remittance history of the remitter information 21a. Here, the fraud detection server 20 determines, as a result of the comparison, that the remittance destination account number 12345 is not included in the remittance history (step S101: YES).

Next, in step S102, the fraud detection server 20 executes a second detection process based on the remittance request information. As a specific example, the fraud detection server 20 compares the remittance amount of 2,000,000 yen included in the remittance request information with a preset amount (100,000 yen in this case). Here, as a result of the comparison, the fraud detection server 20 determines that the remittance amount is greater than the preset amount (step S102: YES).

Next, in step S103, the fraud determination server 20 executes a third determination process based on the number comparison information. As a specific example, the fraud determination server 20 determines that the number comparison information contains "information indicating that the numbers do not match." In other words, the fraud determination server 20 determines that the remitter received a call from an unregistered phone number. In addition, the fraud determination server 20 determines, for example, that the time indicated by the time information (here, 11:11 on Jan. 1, 2021) to the time the remitter performed the remittance procedure (here, 12:11 on Jan. 1, 2021) is within a predetermined time (here, within two hours). Therefore, the fraud determination server 20 determines that the remitter received a call from an unregistered phone number within the predetermined time (step S103: YES).

Next, in step S104, the fraud determination server 20 executes a fourth determination process based on the response history information. Specifically, if the fraud determination server 20 determines that the number comparison information contains "information indicating that the numbers do not match," it identifies "information indicating that the remitter has responded" to a phone number that is not registered. Here, the fraud determination server 20 determines that the remitter responded to an incoming call from an unregistered phone number (step S104: YES).

Next, in step S105, if the conditions of the judgment process in steps S101 to S104 are met, the fraud determination server 20 sends confirmation request information to the verifyers C, D, and E.

Next, in step S106, the terminal device 30 causes the display device 107 to display a confirmation request screen T1 (see FIG. 9) or a confirmation request screen T2 (see FIG. 10) based on the confirmation request information. The terminal device 30 may display the confirmation request screen T1 or T2 in a browser, or may display the confirmation request screen T1 or T2 by push notification based on the device ID through a specific application.

Next, in step S107, the terminal device 30 transmits confirmation result information to the fraud determination server 20 upon receiving operational input from the verifier. As a specific example, when the terminal device 30 receives operational input from the verifier using the permission button T17 or T27, it transmits permission result information to the fraud determination server 20. On the other hand, when the terminal device 30 receives operational input from the verifier using the rejection button T16 or T26, it transmits rejection result information to the fraud determination server 20.

Next, in step S108, the fraud determination server 20 determines whether or not each of the verifyers has rejected the remitter's remittance procedure based on the verification result information. As a specific example, if the fraud determination server 20 obtains rejection result information from at least one of the terminal devices 30 of verifyers C, D, and E, it may send remittance rejection information to the financial institution system 10 (step S108: YES, step S109). Furthermore, if the fraud determination server 20 obtains approval result information from all of the multiple terminal devices 30, it may send remittance execution information to the financial institution system 10 (step S108: NO, step S110).
====Modifications====

With reference to FIG. 14, a modified example of the fraud determination server 20 will be described. FIG. 14 is a diagram showing another example of the functional configuration of the fraud determination server 20. As shown in FIG. 14, the fraud determination server 20 may further have the functions of a setting unit 27 and an identity determination unit 28.

The setting unit 27 sets priorities for multiple verifiers. As an example, when the condition determination unit 23 determines that the remitter meets a predetermined condition, the fraud determination server 20 may transmit remittance approval/disapproval information to the financial institution system based on the confirmation result information transmitted from the terminal device 30 of the verifier who has been set to a high priority by the setting unit 27. Specifically, when the fraud determination server 20 obtains approval result information from the verifier with the first priority and rejection result information from the verifier with the second priority, it may transmit the approval result information to the financial institution system 10. This allows a determination on the remittance procedure to be quickly finalized when multiple verifiers give differing judgments.

As another example, when the condition determination unit 23 determines that the remitter meets a predetermined condition, the fraud determination server 20 may transmit confirmation request information to the verifiers in the order of priority set for the verifiers in the setting unit 27. Specifically, the fraud determination server 20 transmits confirmation request information to the verifier with the first priority. If the verifier with the first priority does not transmit confirmation result information within a predetermined period of time, the fraud determination server 20 transmits confirmation request information to the verifier with the second priority. In this way, the fraud determination server 20 transmits confirmation request information in the order of priority until it obtains confirmation result information from the verifier. In this way, if a judgment by one verifier is delayed, another verifier will make the judgment, thereby preventing delays in the remittance procedure while avoiding fraud damage.

As another example, the fraud determination server 20 may display the confirmation status T28 on the confirmation request screen T2 in descending order of priority set for the confirmers in the setting unit 27. Alternatively, only the confirmers set with the highest priority in the setting unit 27 may be displayed in the confirmation status T28 on the confirmation request screen T2. This allows the confirmer with the highest priority to know whether the confirmer has granted or denied the request, allowing the confirmer who knows this to make a more appropriate decision.

The identity determination unit 28 performs identity verification of the verifyer based on information capable of identifying the verifyer (hereinafter referred to as "personal identification information") transmitted from the verifyer's terminal device 30. Specifically, the terminal device 30 may instruct the verifyer to read personal identification information stored in a medium capable of identifying the verifyer, such as a My Number card, based on a request for identity verification transmitted from the fraud determination server 20. The terminal device 30 reads the personal identification information stored in the medium placed in a predetermined position, for example. The terminal device 30 transmits the personal identification information to the fraud determination server 20. The fraud determination server 20 may verify the legitimacy of the verifyer based on the personal identification information. When the legitimacy of the verifyer is verified, the fraud determination server 20 may transmit verification request information to the terminal device 30. This ensures the legitimacy of the verifyer, thereby more appropriately avoiding fraud damage.

The fraud prevention system 1 may also have a voice notification server. The voice notification server acquires confirmation request information from the fraud determination server 20. The voice notification server issues a voice notification by telephone to the terminal device 30 based on the confirmation request information. The voice notification server also converts the voice data acquired from the verifier through the terminal device 30 into text data. The voice notification server analyzes the text data to determine whether the verifier has approved or rejected the remitter's remittance procedure. The voice notification server transmits information related to the determination result to the fraud determination server 20. The fraud determination server 20 transmits confirmation result information to the financial institution system 10 based on the information related to the determination result. This improves the situation in which the verifier does not notice the confirmation request information.

Furthermore, in the fraud prevention system 1, when the terminal device 40 is an ATM, the financial institution system 10 acquires remittance request information from the ATM. The condition determination unit 23 of the fraud determination server 20 may determine, based on the remittance request information, whether or not the remittance destination linked to the remitter's cash card includes a remittance destination in the remitter's remittance procedure. In this case, if the condition determination unit 23 determines that the remittance destination is not included, the confirmation unit 24 transmits confirmation request information to the terminal device 30. This makes it possible to appropriately avoid fraud damage even in remittance procedures via ATMs.

====Summary====

The fraud prevention system 1 of this embodiment includes an acquisition unit 22 that acquires remittance request information indicating information regarding the remittance request by the remitter, which is sent from the financial institution system 10 that accepts remittance requests by the remitter; a condition determination unit 23 (determination unit) that determines whether or not the information regarding the remitter satisfies a predetermined condition based on the remittance request information; a confirmation unit 24 that transmits confirmation request information indicating information regarding a confirmation request as to whether or not to allow the remittance to multiple confirmers linked to the remitter when the condition determination unit 23 (determination unit) determines that the predetermined condition is met; a remittance processing unit 26 that transmits remittance approval/disapproval information to the financial institution system 10 indicating information regarding whether or not to allow the financial institution system 10 to execute the remittance by the remitter based on confirmation result information indicating information regarding the result of the confirmer's confirmation of the remittance request by the remitter in response to the confirmation request information; and a display control unit 25 that transmits information to the multiple confirmers to identifiably display on the screen the confirmation status of at least one of the multiple confirmers regarding whether or not to allow the financial institution system 10 to execute the remittance by the remitter. This makes it possible to prevent fraudulent remittances based on objective judgment. In addition, it is possible to know whether other verifyers have approved or rejected the remittance, and it is also possible to know which verifyers have already verified the remittance, so that the verifyers can more accurately determine whether the remittance procedure by the remittance sender is correct.

The fraud prevention system 1 of this embodiment further includes a setting unit 27 that sets priorities for multiple verifiers, and the remittance processing unit 26 transmits remittance approval information to the financial institution system 10 based on the confirmation result information acquired from the verifier with the highest priority among the confirmation result information acquired by the acquisition unit 22. This makes it possible to quickly determine a decision on the remittance procedure when multiple verifiers have different opinions.

In the fraud prevention system 1 of this embodiment, when the condition determination unit 23 (determination unit) determines based on the remittance request information that the remittance destination of the remitter is a first-time remittance destination, the confirmation unit 24 sends confirmation request information to multiple confirmers. This allows the fraud determination server 20 to properly identify remittance procedures that are likely to be fraudulent, based on the characteristic that in fraud cases, the remittance destination is often a first-time remittance destination.

In the fraud prevention system 1 of this embodiment, the confirmation unit 24 sends confirmation request information to multiple confirmers when the condition determination unit 23 (determination unit) determines based on the remittance request information that the remittance amount of the remitter is equal to or greater than a predetermined amount. This allows the fraud determination server 20 to recognize that fraudulent remittance amounts are often large, and appropriately determine which remittance procedures are likely to be fraudulent.

In the fraud prevention system 1 of this embodiment, the acquisition unit 22 acquires from the remitter number comparison information indicating information related to the results of comparing the telephone number registered by the remitter with the telephone number at which the remitter received a call, and the confirmation unit 24 sends confirmation request information to multiple confirmers when the condition determination unit 23 (determination unit) determines based on the number comparison information that the telephone number at which the remitter received a call within a specified period of time is not included in the telephone numbers registered by the remitter. In this way, the fraud determination server 20 can grasp the characteristic that fraud often involves calls from telephone numbers not registered in the telephone directory, and appropriately determine which remittance procedures are likely to be fraudulent.

In the fraud prevention system 1 of this embodiment, the acquisition unit 22 further acquires response history information indicating information regarding the response records to telephone numbers received by the remitter, and the confirmation unit 24 sends confirmation request information to multiple confirmers when the condition determination unit 23 (determination unit) determines, based on the number comparison information and the response history information, that the telephone number received by the remitter within a specified period of time is not included in the telephone numbers registered by the remitter and the remitter responded to a telephone number that is not registered. In this way, the fraud determination server 20 can grasp the characteristic that in fraud cases, there is often an incoming call from a telephone number that is not registered in the telephone directory and that the remitter responds to this call, and appropriately determine which remittance procedures are likely to be fraudulent.

In the fraud prevention system 1 of this embodiment, the acquisition unit 22 acquires from the remitter number comparison information indicating information on the result of comparing the telephone number registered by the remitter with the telephone number to which the remitter received a call, and the condition determination unit 23 (determination unit) determines whether the remittance destination is the first remittance destination for the remitter based on the remittance request information, determines whether the remittance amount by the remitter is equal to or exceeds a predetermined amount, and determines whether the telephone number to which the remitter received a call within a predetermined period is included in the telephone numbers registered by the remitter based on the number comparison information, and the confirmation unit 24 transmits confirmation request information to multiple confirmers when the condition determination unit 23 (determination unit) determines that the remittance destination is the first remittance destination, that the remittance amount is equal to or exceeds a predetermined amount, and that the telephone number to which the remitter received a call within a predetermined period is not included in the telephone numbers registered by the remitter. In this way, the fraud determination server 20 can appropriately distinguish fraud of various methods by combining various determination processes, and can appropriately determine remittance procedures that are likely to be fraudulent.

In the fraud prevention system 1 of this embodiment, the financial institution system 10 accepts a remittance request from a remitter via the remitter's mobile terminal. This makes it possible to prevent the remitter from falling victim to fraud based on objective judgment.

In the fraud prevention system 1 of this embodiment, the financial institution system 10 accepts a remittance request from a remitter via an ATM at the financial institution, and the confirmation unit 24 sends confirmation request information when the condition determination unit 23 (determination unit) determines, based on the remittance request information, that the remittance destination (first remittance destination) linked to the remitter's cash card does not include the remittance destination in the remittance request by the remitter (second remittance destination). This makes it possible to appropriately avoid fraud damage even when performing remittance procedures via ATM.
