It is a figure which shows the example of the top screen displayed on the display of a customer terminal according to one Embodiment of this invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic diagram showing a system environment according to an embodiment of the present invention. The environment 100 includes a store terminal 110, a customer terminal 120, and a store server system 130. The branch office terminal 110 and the customer terminal 120 are terminals installed at a bank branch office or a branch consultation counter. The branch office terminal 110 is a terminal operated by a bank clerk, and is connected to a bank branch office server system 130 via a dedicated line. The branch terminal 110 may be a computer that includes at least one processor and is connected to an input device such as a mouse and a keyboard, an output device such as a display, and peripheral devices such as a card reader 112. The customer terminal 120 is a terminal used by a customer, and is associated with a specific store terminal 110. The customer terminal 120 can be communicatively connected to a specific store terminal 110 and store server system 130 to which the customer terminal 120 is linked. The customer terminal 120 can be preferably a tablet-type terminal, but a desktop, laptop, or notebook computer can also be used. For example, when a bank employee responds to a customer at a bank consultation counter, the bank employee uses the sales office terminal 110, and the customer uses the customer terminal 120 linked to the sales office terminal 110 used by the bank employee. It can be used to perform operations necessary for desired procedures such as procedures related to Internet banking.

  Connected to the branch terminal 110 is a card reader 112 for reading magnetic or IC card information and biometric information such as vein information. When the reading device 112 reads magnetic or IC card information and / or biometric authentication information, the branch terminal 110 transmits the information to the control server 140 as customer authentication information. The reading device 112 can be a magnetic card, a contact / non-contact IC card, and an integrated pin pad that can read biometric authentication information. An apparatus can also be used. Alternatively, for example, when customer authentication is performed using a credit card, a loan card, a desired membership card, a point card, or the like, a reading device that can read the card information can be used. When the customer authentication information is acquired from the reading device 112, the sales office terminal 110 transmits the acquired authentication information to the control server 140 in the sales office server system 130. In the case of biometric authentication, the store terminal 110 can also transmit information such as the card valid start date, expiration date, and authentication result to the store terminal 130.

  By the way, the login method of Internet banking varies depending on the type of cash card used by the customer, and there are a password login method, a magnetic or IC cash card login method, a biometric authentication login method, and the like. For example, when a procedure related to internet banking is performed at a consultation counter, the customer causes the reading device 112 to read the cash card (or biometric authentication information) to be used and a login method that matches the type of the cash card for the customer. It is necessary to specify from the terminal 120. When the login method is specified by the customer, the customer terminal 120 transmits the specified login method information to the control server 140 together with the computer name of the customer terminal 120 and the time when the login method is specified. The control server 140 determines whether the authentication information received from the branch office terminal 110 matches the designated login method.

  As described below, the customer can select a desired procedure from a menu screen (for example, the top screen of FIG. 4) displayed on the display of the customer terminal 120. Can be controlled to require the permission of a clerk depending on the type of procedure. Alternatively, it is possible to perform control so that the procedure from the customer terminal 120 is permitted only when the employee is logged in to the branch terminal 110 linked to the customer terminal 120. Thereby, security can be ensured and an erroneous operation can be prevented. In this specification, an embodiment in which one customer terminal is associated with one branch terminal will be described. However, a plurality of customer terminals are associated with one branch terminal, It is also possible to link other terminals.

  The branch office server system 130 includes various databases such as a control server 140, a terminal association table 142, a clerk information table 144, and a customer authentication information table 146.

  The control server 140 is connected to the branch terminal 110 and the customer terminal 120 linked to the branch terminal 110, and controls the branch terminal 110 and the customer terminal 120 to be linked. When the control server 140 receives the login information of the employee from the sales office terminal 110, the control server 140 stores it in the employee information table 144 as the presence information of the operator. Further, the control server 140 stores the customer authentication information from the branch terminal 110 and the login method information from the customer terminal 120 in the customer authentication information table 146. Even when an asynchronous operation is separately performed on the branch terminal 110 and the customer terminal 120, information input from each terminal is shared by each terminal by the control server 140. It becomes possible. The function of the control server 140 will be described in detail below with reference to FIGS.

  The terminal association table 142 stores association information between the branch terminal 110 and the customer terminal 120. For example, the terminal association table 142 stores the identification information of the branch terminal 110 such as the computer name and the terminal number and the identification information of the customer terminal 120 to be used together with the branch terminal 110 in association with each other. The branch terminal 110 and / or the control server 140 can identify one or more customer terminals 120 corresponding to the branch terminal 110 with reference to the terminal association table 142.

  The employee information table 144 is a table that stores login information to the store terminal 110 by employees. For example, when a certain employee logs in to the sales office terminal 110, the control server 140 displays the ID information of the employee along with information such as the computer name, IP address, terminal machine number, and time stamp of the logged-in sales office terminal 110. Stored in the staff information table 144 as operator affiliation information. When the employee logs out from the sales office terminal 110, the control server 140 updates the operator presence information stored in the employee information table 144.

  The customer authentication information table 146 is a table that stores customer authentication information (for example, customer cash card information, biometric information, etc.). As described above, the branch office terminal 110 transmits customer authentication information such as cash card information and biometric authentication information read via the reading device 112 to the control server 140. The control server 140 stores the customer authentication information received from the branch terminal 110 and information such as the computer name, terminal number, and terminal installation store number of the branch terminal 110 that acquired the authentication information together with a time stamp. Stored in 146. When the control server 140 receives the login method designation from the customer terminal 120, the control server 140 displays the received login method information together with the computer name of the customer terminal 120 and the login method designation at the customer authentication information table 146. To store.

  The branch office server system 130 further includes a customer entry sample database 132 and a foreign remittance request database 134. The customer entry sample database 132 stores entry sample data of various documents to be entered by customers in bank procedures such as application forms. For example, when the customer entry sample menu is selected at the customer terminal 120 after confirming the purpose of visiting the store, the branch office server system 130 retrieves appropriate entry sample data from the customer entry sample database 132 and stores it in the customer terminal 120. Send and display to customers. As a result, the procedure can be navigated more quickly and easily than the paper-based entry sample used conventionally.

  The foreign remittance request database 134 stores foreign remittance request data created by the customer. The customer terminal 120 holds a template for preparing a foreign remittance request form, and the customer can input data necessary for foreign remittance from the customer terminal 120 along the template. The customer terminal 120 adds a serial number to the input foreign remittance request data and transmits it to the sales office server system 130, and the transmitted foreign remittance request data is stored in the foreign remittance request database 134 of the sales office server 130. Stored. Thereafter, the bank employee can extract the desired foreign remittance request form data from the foreign remittance request form database 134 by the serial number at the branch terminal 110, and the extracted foreign remittance request form is connected to the branch terminal 110. The foreign remittance request form can be completed by printing from the output device. Such a configuration is particularly advantageous because foreign remittance requires the entry of various items. Further, since the foreign remittance request form created from the customer terminal 120 can be output from the branch terminal 110, it is advantageous in that it is not necessary to provide a separate output device for the customer terminal 120. The store server system 130 can also hold screen information such as a menu screen to be displayed on the store terminal 110 and the customer terminal 120 (not shown).

  The environment 100 further includes an internet banking system 150, where the customer authenticates login information such as a personal identification number, and executes various transactions in the internet banking service.

  Next, with reference to FIG. 2, a process for starting the sales office terminal and the customer terminal in conjunction with each other according to an embodiment of the present invention will be described.

In step 202, the branch terminal 110 is activated. For example, the branch terminal 110 is activated when the power is turned on by a bank clerk.
In step 204, the branch office terminal 110 refers to the terminal association table 142 to identify the customer terminal 120 corresponding to the branch office terminal 110, and in step 206, issues an activation command to the identified customer terminal 120. To do.
In step 208, the customer terminal 120 is activated in response to an activation command from the branch terminal 110. When the activation is completed, the customer terminal 120 transmits an activation completion notification to the control server 140 in step 210.

  When the control server 140 receives the activation completion notification from the customer terminal 120 in step 212, the control server 140 acquires screen information to be displayed on the display on the customer terminal 120 in step 214. For example, the customer terminal 120 can acquire information on a top screen (for example, FIG. 4) that displays various service menus that can be guided at a consultation desk.

  On the other hand, for example, the employee inputs his / her ID information to the branch terminal 110 or sets his / her ID card in the reading device 112 (or other authentication device) connected to the branch terminal 110. When logging in to the store terminal 110, login information indicating that the employee has logged in to the store terminal 110 is transmitted from the store terminal 110 to the control server 140 (steps 216 and 218).

  When the control server 140 receives the login information of the clerk from the branch terminal 110, in step 220, the control server 140 stores it in the clerk information table 144 as operator presence information. In the employee information table 144, for example, the employee ID information, the computer name of the branch office terminal 110 to which the employee logged in, the IP address of the terminal, the terminal machine number, the terminal installation shop number, and the system in which the control server 140 has received the login information. Information such as a time stamp indicating the time is stored.

  In this embodiment, the customer terminal 120 is activated in conjunction with the activation of the sales office terminal 110. However, the customer terminal 120 activates the sales office terminal 110 by pressing a power button or the like. It can also be started manually separately.

  Next, referring to FIG. 3, a process for operating a branch terminal and a customer terminal corresponding to the branch terminal in the Internet banking service in accordance with one embodiment of the present invention will be described.

  In step 302, the process starts when an internet banking service is selected from the top screen displayed on the display of the customer terminal 120. The top screen displayed on the display of the customer terminal 120 is provided from the control server 140. For example, as illustrated in FIG. 4, in addition to the Internet banking service, guidance information on the internal web of the bank (for example, Information on yen deposit interest rates, foreign currency deposit interest rates, foreign exchange rates, etc.), menus for creating remittance request forms, sample forms for forms, etc. can do.

  In step 304, the customer terminal 120 receives a selection of a login method for the Internet banking service by the customer. As described above, the login method of the Internet banking service includes a password login method, a biometric login method, and an IC card login method. For example, when an internet banking service is selected from the top screen of the customer terminal 120, a login method selection screen is displayed, and the customer can specify which login method to use.

  In step 306, the customer terminal 120 transmits a login method notification message for notifying the login method designated by the customer to the control server 140. The login method notification message includes the login method information designated by the customer, the login linkage serial number (for example, the combination of the computer name of the customer terminal 120 and the time at which the login method is designated), and the branch terminal 110. And the identification information of the branch office terminal 110 associated with the customer terminal 120, such as

  When receiving the login method notification message from the customer terminal 120, the control server 140 registers information in the login method notification message in the customer authentication information table 146 in step 308.

  When the customer terminal 120 transmits a login method notification message to the control server 140, the customer terminal 120 enters a state of waiting for acquisition of customer authentication information, and in step 310, displays a screen for requesting the customer to read a cash card.

  On the other hand, in step 312, the branch terminal 120 enters a cash card information reading preparation state, and a customer sets a cash card in the reader 112 connected to the branch terminal 110 and / or performs biometric authentication. In step 314, the reading device 112 acquires customer authentication information such as cash card information or biometric authentication information, and provides the acquired authentication information to the branch terminal 110.

  In step 316, the branch office terminal 110 displays a notification that the authentication information has been provided from the reading device 112 on the display and requests confirmation from the bank employee. When the authentication information is confirmed by the employee (for example, pressing the OK button), the branch office terminal 110 transmits the customer authentication information to the control server 140 in step 318.

  In step 320, the control server 140 determines whether or not the customer authentication information received from the branch terminal 110 matches the login method registered in the customer authentication information table 146. For example, when the customer login method registered in the customer authentication information table 146 is a biometric authentication login method, it is determined whether or not the received authentication information is biometric authentication information. Similarly, when the customer login method is the IC card login method, it is determined whether the received authentication information is the IC card information.

  When the received authentication information matches the registered login method, the control server 140 in step 322, the customer authentication information (for example, cash card information, biometric information (and card valid start date) , Expiration date, authentication result, etc.), information such as the computer name of the branch office terminal 110 that acquired the authentication information, the terminal machine number, and the terminal installation shop number are registered in the customer authentication information table 146 together with the time stamp. Further, the control server 140 provides the authentication information to the customer terminal 120 in step 324. In addition, when the authentication information is not provided from the control server 140 within a predetermined time after the customer terminal 120 enters the authentication information acquisition waiting state, the processing is timed out and an error is displayed as an option. You can also Since the time when the customer terminal 120 transmits the login method notification message to the control server 140 and enters the authentication information acquisition waiting state is stored as the login cooperation serial number, it is predetermined from the time when this login method notification message is transmitted. When the time elapses, a dialog showing an error such as a timeout can be displayed on the display, and the screen can be changed to the top screen.

  In step 326, when the customer terminal 120 receives the authentication information from the control server 140, the customer terminal 120 displays a login screen of the Internet banking service and requests the customer to input login information (such as a password).

  When the customer inputs the password from the customer terminal 120 and presses the login button, the customer terminal 120 transmits login information to the Internet banking system 150 in step S328. Thereby, the authentication process in the internet banking system 150 is performed.

  If the authentication is successful, in step S330, the customer terminal 120 receives the login success screen information from the Internet banking system 150, and displays the login success screen of the Internet banking service on the display.

  As a result, the customer's Internet banking service can be traded via the customer terminal 120. For example, the customer terminal 120 acquires transaction screen information from the Internet banking system 150 and displays the transaction screen on the display. The customer selects a desired transaction from the transaction screen of the customer terminal 120 and inputs necessary information. The customer terminal 120 acquires clerk authentication screen information from the internet banking system 150, requests the clerk's authentication for the transaction content input by the customer, and transmits the transaction information to the internet banking system 150 when the authentication is obtained.

  In addition, when using the customer terminal 120, it is possible to require use by a bank clerk depending on the content to be accessed from the customer terminal 120. For example, when using the customer terminal 120 to access an internet banking service or an external Web, the permission of a clerk is required, while when preparing a remittance request form, the permission of the clerk is not required. In addition, the processing can be continued. For example, when accessing the internet banking service using the customer terminal 120, when the internet banking service is selected from the top screen displayed on the display of the customer terminal 120, the customer terminal 120 connects to the control server 140. On the other hand, a staff permission screen is requested, and a staff permission screen received from the control server 140 is displayed on the display to request permission of the staff. Then, when the clerk inputs permission information (for example, pressing the OK button) from the customer terminal 120, the screen shifts to the next screen, and when the clerk permission information cannot be acquired, an error message is displayed. It can be configured to return to the top screen. Thereby, the security can be further strengthened. Alternatively, when the clerk is logging in to the branch terminal 110 associated with the customer terminal 120, for example, when login information to the clerk's branch terminal 110 is acquired from the clerk information table 144, the permission of the clerk As a result, access to the customer terminal 120 linked to the branch terminal 110 can be permitted.

  FIG. 4 shows an example of the top screen displayed on the display of the customer terminal. For example, when the customer touches and selects one of “first password login”, “CD password login”, and “biological CD login” from the items in “procedure” from this top screen, the selected item Is designated as the login method in the Internet banking service (for example, step 304 in FIG. 3). When the customer selects “Create foreign remittance request form”, the customer terminal 120 displays a template for the foreign remittance request form. Thereafter, the customer can input necessary information using the template displayed on the customer terminal 120 and create a foreign remittance request form. As described above, the prepared foreign remittance request form data is stored in the foreign remittance request form database 134 of the sales office server 130 with a serial number added. When the customer selects “form entry sample”, the customer terminal 120 requests the form entry sample menu from the control server 140, and the control server 140 retrieves an appropriate form entry sample from the customer entry sample database 132. To the customer terminal 120.

  In this way, the customer terminal 120 can communicate with the branch terminal 130 and provide appropriate navigation in bank services according to the item selected by the customer. Note that the screen illustrated in FIG. 4 is an example, and other menu items can be set.
