  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration example of a computer system including an authentication proxy server according to the present embodiment.

  There are a plurality of financial institutions (in this embodiment, two financial institutions A and B). The financial institution A has one or more ATMs (automated teller machines) 1 installed in its premises or convenience store. The financial institution A issues an ATM card to an account opener of the financial institution A (a person who has opened an account with the financial institution A). Here, the ATM card means that the ATM card owner uses the ATM 1 to perform various processes on the ATM card owner's account (for example, deposit process, withdrawal process, balance inquiry process, Hereinafter, it refers to a card (for example, a cash card) that can be instructed (account processing). On the other hand, financial institution B does not have ATM1. Financial institution B does not issue an ATM card to an account opener of financial institution B (a person who opened an account in financial institution B).

  The financial institution A has a financial institution A server 3. The financial institution B has a financial institution B server 4. The financial institution A server 3 is a server machine used by the financial institution A to manage its account (an account opened in the financial institution A). On the other hand, the financial institution B server 4 is a server machine used by the financial institution B to manage its account (an account opened in the financial institution B). Each of the financial institution A server 3 and the financial institution B server 4 is connected to a communication network (hereinafter referred to as “ATM network”) 2 for communicating with the ATM 1. One or more ATMs 1 are connected to the ATM network 2. The ATM 1 shown in FIG. 1 is an ATM installed by the financial institution A, for example. In the following description, the financial institution A server 3 and the financial institution B server 4 are collectively referred to as “financial institution server”.

  The financial institution servers 3 and 4 include, for example, ATM message processing units 31 and 41 and memories 32 and 42. The functions of the ATM message processing units 31 and 41 are realized by, for example, a CPU (not shown) included in the financial institution servers 3 and 4 executing predetermined programs stored in the memories 32 and 42.

  The ATM message processing units 31 and 41 are processing units that perform account processing for a specified account in accordance with the received ATM message. Here, the ATM telegram refers to instruction data transmitted to the financial institution servers 3 and 4 to instruct the ATM 1 to perform a specific account process. For example, when the financial institution A server 3 receives an ATM message (hereinafter referred to as “withdrawal instruction message”) from the ATM 1 instructing the withdrawal process, the ATM message processing unit 31 of the financial institution A server 3 In accordance with the received withdrawal instruction message, the withdrawal process for the designated financial institution A account (the ATM1 operator's account) is performed (that is, the designated amount is withdrawn from the ATM1 operator's account). .

  When account processing is performed in accordance with an ATM message, authentication is performed to determine whether or not the ATM1 operator who instructed the account processing is a legitimate person (account opener of the specified account). Is called. For example, when the financial institution A server 3 performs account processing in accordance with the received ATM instruction message, whether or not the operator of the ATM 1 instructing the account processing is a valid account opener of the financial institution A. Authentication (hereinafter, “account opening person authentication of financial institution A”) is performed. The account holder authentication of the financial institution A is performed by, for example, the ATM message processing unit 31 of the financial institution A server 3. The ATM message processing unit 31 of the financial institution A server 3 includes, for example, data recorded on an ATM card (issued by the financial institution A) inserted into the ATM 1 (hereinafter “recorded data”), ATM 1 The account opener authentication of the financial institution A is performed based on the personal identification number (the personal identification number set in the designated account (an account of the financial institution A)) input to the ATM 1 by the operator.

  The financial institution A server 3 corresponds to the authentication proxy server according to the present embodiment. The financial institution A server 3 performs processing other than the financial institution A in addition to the processing performed by the ATM telegram processing unit 31 (that is, account processing for the account of the financial institution A according to the received ATM telegram). Processing for enabling an account opener of an institution (for example, financial institution B, hereinafter referred to as “other financial institution”) to instruct account processing for its own account in the other financial institution using ATM1. I do. Specifically, the financial institution A server 3 operates the ATM 1 and the person (or the person who has instructed) who is instructing the account processing for the account of another financial institution is a valid account opener of the other financial institution. (Hereinafter referred to as “account opener authentication of other financial institutions”). Then, when the financial institution A server 3 succeeds in the account opener authentication of the other financial institution, the financial institution server of the other financial institution sends an ATM message instructing the account processing designated by the operator of the ATM 1. 4 is transmitted. Hereinafter, processing performed by the financial institution A server 3 (processing for allowing an account opener of another financial institution to instruct account processing using ATM 1) is referred to as “authentication proxy processing”.

  Normally, for financial institutions that do not install ATM1 or issue ATM cards, such as financial institution B, the account opener cannot use ATM1 to instruct account processing for that account, but authentication By performing the proxy process, it becomes possible to instruct account processing using ATM1 for such a financial institution.

  The account opener authentication of another financial institution in the authentication processing is the recorded data of the ATM card (issued by the financial institution A) inserted in the ATM 1 and the password entered by the ATM 1 operator into the ATM 1 (A personal identification number set in a designated account (an account of another financial institution)). That is, an ATM card issued by the financial institution A is used for account establishment authentication of other financial institutions. Therefore, in the present embodiment, account processing for an account of another financial institution is performed using a function provided by the financial institution A server 3 (a function realized by authentication proxy processing, hereinafter referred to as “authentication proxy function”). Those who can give instructions are those who have opened an account in each of the other financial institution and financial institution A. Details of the authentication proxy process will be described later with reference to FIG.

  In addition to the ATM message processing unit 31 and the memory 32, the financial institution A server 3 includes an authentication agent processing unit 33 that performs the authentication agent processing. In addition, authentication proxy management data 5 is stored in the memory 32 of the financial institution A server 3. Similar to the ATM message processing unit 31, the function of the authentication proxy processing unit 33 is realized by the CPU provided in the financial institution A server 3 executing a predetermined program stored in the memory 32.

  FIG. 2 is a diagram illustrating an example of the authentication proxy management data 5.

  The authentication proxy management data 5 is data that is referred to when the authentication proxy processing unit 33 performs the authentication proxy processing. As shown in FIG. 2, the authentication agency management data 5 includes data relating to an account of a financial institution A (hereinafter “account data of financial institution A”) 51 and data relating to an account of another financial institution (hereinafter referred to as “others”). Financial institution account data ") 52, and the data 51 and 52 are managed in association with each other. The account data 51 of the financial institution A includes, for example, data (for example, a branch name 511 and an account number 512) for specifying an account opened in the financial institution A. Further, the account data 52 of another financial institution includes, for example, data (for example, the financial institution name 521, the branch name 522, and the account number 523 of the other financial institution) for specifying an account opened in the other financial institution. It is. The account data 52 of another financial institution also includes a password 524 set for the account specified by the account data 52.

  As for the account data 52 of another financial institution, the account opener of the account indicated by the account data 51 of the financial institution A associated with the data 52 can instruct account processing using the authentication proxy function. Indicates an account of another financial institution (hereinafter referred to as “authentication agency account”). That is, in the example of FIG. 2, the data 53 in the first column indicates that the account opener of the account with the account number “XXX” uses the authentication proxy function to set the account number “XXX” of the financial institution B. This indicates that it is possible to instruct account processing for an account of “×”.

  For example, the account opener of the financial institution A can register the specified account in advance in the financial institution A server 3 as an authentication proxy account by applying to the financial institution A for registration of the authentication proxy account. Then, at the time of registration (or after that), a password is set in the registered authentication proxy account (the password 524 indicates the password set in the authentication proxy account).

  In the example of FIG. 2, one authentication agency account is associated with one financial institution A account, but a plurality of authentication agency accounts are associated with one financial institution A account. It may be attached. That is, one account opener of the financial institution A can register a plurality of authentication agency accounts.

  FIG. 3 is a flowchart illustrating the authentication proxy process. FIG. 3 shows a case where an ATM 1 operator uses an ATM card issued by financial institution A and operates ATM 1 to perform account processing for his / her own account of another financial institution (in this example, financial institution B). An example is shown.

  First, the ATM operator inserts an ATM card issued by the financial institution A into ATM1 (S1).

  The ATM 1 that accepts the insertion of the ATM card reads the recorded data of the inserted ATM card. The record data includes, for example, data indicating that the ATM card is issued by the financial institution A, and data indicating the account of the owner of the ATM card (an account of the financial institution A) (for example, a branch name) And account number). The ATM 1 notifies the read record data to the financial institution A server 3 (S2).

  When the financial institution A server 3 receives the recorded data from the ATM 1, the ATM message processing unit 31 of the financial institution A transmits the data that is the basis of the service menu screen 110 of the financial institution A to the ATM 1, and the input / output unit of the ATM 1 11 displays the service menu screen 110 of the financial institution A (S3). The service menu screen 110 of the financial institution A is a screen for instructing an operator of the ATM 1 to perform account processing for the account of the financial institution A, for example, as shown in FIG. As shown in FIG. 4, on the service menu screen 110 of the financial institution A, for example, menu items for instructing account processing (payment processing, withdrawal processing, balance inquiry processing, etc.) are displayed. In addition to the menu items described above, the service menu screen 110 of the financial institution A is a screen for instructing the ATM 1 operator to perform account processing for an account (authentication agency account) of another financial institution (hereinafter referred to as “others”. A menu item (“other financial institution” in the example of FIG. 4) 111 for screen transition to the “service menu screen of financial institution”) is also displayed.

  Here, the operator of ATM 1 selects the menu item 111 of “other financial institution” on the service menu screen 110 of the financial institution A (S4).

  Upon receiving the selection of the “other financial institution” menu item 111, the ATM 1 notifies the financial institution A server 3 that the screen transition to the service menu screen of the other financial institution has been instructed (S5).

  When the financial institution A server 3 receives the notification of step S5 from the ATM 1, the authentication agency processing unit 33 of the financial institution A server 3 refers to the authentication agency management data 5 and is indicated by the recording data notified in step S2. The account data 52 of another financial institution associated with the account (the account of the financial institution A of the operator of ATM 1) is acquired. The account data 52 of another financial institution acquired here indicates an authentication agency account (authentication agency account of the ATM1 operator) registered in advance by the ATM1 operator. In this example, it is assumed that the authentication agent account of the ATM1 operator is an account of the financial institution B.

  If the account data 52 of another financial institution is not associated with the account indicated by the recording data notified in step S2 (the account of the financial institution A of the operator of ATM1), there is no authentication agent account. The authentication agent processing unit 33 cannot perform the authentication agent processing (that is, the ATM1 operator cannot use the authentication agent function). Accordingly, in order to inform the ATM 1 operator in advance of this, for example, when there is no authentication agent account, the authentication agent processor 33 displays the service menu screen 110 of the financial institution A displayed in step S3. The menu item 111 of “other financial institution” can be prevented from being displayed.

  The authentication agent processing unit 33 generates data as a basis of the authentication screen 120 based on the acquired account data 52 of another financial institution, transmits the generated data to the ATM 1, and sends an authentication screen to the input / output unit 11 of the ATM 1. 120 is displayed (S6). As shown in FIG. 5, the authentication screen 120 displays a display area for information (for example, financial institution name (financial institution B in this example), branch name, account number, etc.) indicating the ATM 1 operator's authentication proxy account. 121, an area 122 for inputting a personal identification number, and a confirmation button 123 for confirming the input of the personal identification number are displayed.

  Thereafter, the ATM1 operator inputs the password set in the authentication account of the ATM1 operator (in this example, the account of the financial institution B) displayed in the display area 121 on the authentication screen 120, The confirmation button 123 is pressed (S7).

  The ATM 1 that has received the input of the personal identification number notifies the financial institution A server 3 of the accepted personal identification number (S8).

  When the financial institution A server 3 receives the password notification from the ATM 1, the authentication agent processing unit 33 of the financial institution A performs account opener authentication of another financial institution (financial institution B) (S9). Specifically, the authentication agent processing unit 33 determines whether or not the personal identification number notified from the ATM 1 matches the personal identification number 524 included in the account data 52 of the other financial institution acquired in step S6. judge. Then, the authentication agent processing unit 33 determines that the operator of the ATM 1 is a legitimate account opener of the financial institution B (ie, another financial institution (the financial institution B) ) Has successfully authenticated the account opener).

  If the account opener authentication of another financial institution (financial institution B) is successful, the authentication agent processing unit 33 transmits the data that is the basis of the service menu screen 130 of the financial institution B to the ATM 1, and the input / output unit of the ATM 1 11 displays the service menu screen 130 of the financial institution B (S10). The service menu screen 130 of the financial institution B is a screen for instructing the operator of the ATM 1 to perform account processing for the account of the financial institution B (authentication agency account), and is, for example, shown in FIG. As shown in FIG. 6, the service menu screen 130 of the financial institution B includes, for example, a display area 131 for information (for example, branch name, account number, etc.) indicating an authentication agent account of the ATM 1 operator, and account processing. A menu item 132 for instructing (payment processing, withdrawal processing, balance inquiry processing, etc.) is displayed.

  Here, the operator of ATM 1 selects one of the menu items 131 for instructing any account processing on the service menu screen 130 of the financial institution B (S11). Hereinafter, the account processing instructed in step S11 is referred to as “designated account processing”.

  The ATM 1 that has received the selection of the menu item 131 for instructing the designated account processing notifies the financial institution A server 3 that the designated account processing has been instructed (S12).

  When the financial institution A server 3 receives the notification in step S12 from the ATM 1, the authentication agency processing unit 33 of the financial institution A server 3 instructs the ATM 1 operator to perform designated account processing on the authentication agency account. A telegram is generated, and the generated ATM telegram is transmitted to the financial institution B server 4 (S13, S14).

  When the financial institution B server 4 receives the ATM telegram from the financial institution A server 3, the ATM telegram processing unit 41 of the financial institution B server 4 applies the authentication account of the ATM 1 operator according to the received ATM telegram. Then, the designated account process is performed (for example, when the designated account process is a withdrawal process, the designated amount is withdrawn from the authentication agent account of the ATM1 operator) (S15). Then, the ATM message processing unit 41 of the financial institution B server 4 transmits result data indicating the result of the designated account processing to the financial institution A server 3. The result data includes, for example, information indicating whether or not the designated account processing is successful, a balance after the designated account processing, and the like.

  When the financial institution A server 3 receives the result data from the financial institution B server 4, the authentication agent processing unit 33 of the financial institution A server 3 transmits the data that is the basis of the result screen 140 to the ATM 1, and the input / output unit of the ATM 1 11 displays the result screen 140 (S16). As shown in FIG. 7, on the result screen 140, for example, when the designated account processing is successful, a message display area 141 and a balance display area 142 after the designated account processing are displayed. Is done.

  The above is the description of the authentication proxy process. As a result of the above processing, even for other financial institutions such as financial institution B that do not install ATM1 or issue ATM cards, their account holders use ATM1 to make their own account at the other financial institution. It becomes possible to instruct the account processing for the account. In other words, even for other financial institutions that do not install ATM1 or issue ATM cards, it is possible to provide services using ATM1 to their account openers without installing ATM1 or issuing ATM cards. Become.

  The above-described embodiments of the present invention are examples for explaining the present invention, and are not intended to limit the scope of the present invention only to those embodiments. The present invention can be implemented in various other modes without departing from the gist thereof.

  For example, in this embodiment, it is assumed that the person who can instruct account processing for an account of another financial institution using the authentication proxy function is a person who has opened an account in each of the other financial institution and financial institution A. However, for example, by performing the following, the financial institution A server 3 can provide an authentication proxy function to an account opener of another financial institution that has not opened an account in the financial institution A.

  That is, the financial institution A issues an ATM card to a person who does not have an account with the financial institution A but wants to use the authentication proxy function (function user). For example, an ID for specifying a function user is recorded on the ATM card. Then, the financial institution A manages the association between the functional user and the authentication surrogate account by using the ID for specifying the functional user in the authentication surrogate management data 5 instead of the account data 51 of the financial institution A. Keep it. As a result, the financial institution A server 3 executes the same processing flow as in FIG. 3 to provide an authentication agent function to account openers of other financial institutions that have not opened an account with the financial institution A. become able to.
