[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an inter-program linkage control method for a computer terminal device such as a personal computer, and in particular, as in a billing system of a financial institution, checks an operator, limits operations that can be traded for each operator, and further handles it. Depending on the amount of money, it relates to a business linkage control method in a system that requires security to obtain approval from the officers.
[0002]
[Prior art]
In a conventional financial institution account system, as in the case of searching customer information in an information system and subsequently performing deposit / save / withdrawal transactions in the account system, the account system and the information system or OA with the same customer. When processing system systems continuously, once the information system is traded, take a note of the transaction result or make a hard copy, and enter the data by referring to the memo or hard copy in the account system transaction. Had gone. Or, conversely, after inquiring transaction of the accounting system, the transaction result is written down or hard-copied, and the information system or OA system is consulted for financing.
[0003]
On the other hand, in programs such as databases, word processors, and spreadsheets, application systems can be easily constructed by the program linkage function. However, the accounting system often uses dedicated hardware or OS, and information system or OA. It was physically difficult to link the program between the system and the accounting system.
[0004]
[Problems to be solved by the invention]
In the above conventional technology, the accounting system is built on original hardware and OS, so the information system such as database used in banking business and OA system such as word processor and spreadsheet used in office work are linked with the program. It was difficult to do so, and performing a cross-system transaction required laborious operations.
[0005]
In addition, the account system guards that only an operator who has an ID card can operate, further restricts the operator's transaction range, and performs checks and management that require approval of officers at high prices However, if security is ensured and the information system or OA system is linked to the program and the accounting system can be easily used from the information system or OA system, there is a problem that security against illegal transactions cannot be secured.
[0006]
An object of the present invention is to provide a business cooperation control method in which security is maintained.
[0007]

This is the format of the message sent to the server when the message through function is used.
[0015]
Hereinafter, an embodiment will be described with reference to FIGS. 1 to 11.
[0016]
In FIG. 1, the general-purpose platform 104 can execute a plurality of programs simultaneously. When a plurality of programs are executed simultaneously, one of the programs is in an active state. The program in the active state is preferentially displayed on the display unit 108 and receives input from the operation unit 105. The priority display is performed by the display control unit 109, and the input of the operation unit 105 is transmitted to the active application by the input control unit 107. The operation unit 105 is provided with a key dedicated to billing processing and a magnetic card reader, in addition to a general-purpose key. The hardware control of the operation unit 105 is performed by a dedicated KB driver 106. When the billing program is active, the numeric task 209 instructs the KB driver 106 to operate in the billing mode. As a result, when there is an input to the account processing key and the magnetic card reader, the corresponding key code is transmitted to the input control unit 107. When the accounting system program is inactive, that is, when the information system or OA system program becomes active, the numeric task 209 instructs the KB driver 106 to operate in the general-purpose mode. An invalid key code is transmitted to the system / OA program.
[0017]
At the time of environment construction, since the system start / end task 201 is defined to be executed in the general platform initial file (file for setting the initial setting information), when the general platform 104 starts up by turning on the power (FIG. 4). In step S401, the system start / end task 201 is executed, the tasks from the business cooperation task 202 to the reception control task 221 and the library group 230 are loaded and initialized, and the accounting program 114 is started (S402). Thereafter, the billing program 114 remains executed until the general-purpose platform 104 is stopped.
[0018]
When the billing program 114 is executed, a menu is first displayed (S405). In the menu, you can select account / information / OA processing. In order to perform information processing, information processing is selected from the menu screen (S406). The account system program 113 activates the information system program 118 after canceling the operator registration and disconnecting the line (S408). The activated information system program 118 becomes active, and the operator can perform information system processing.
[0019]
When accessing the information system host 102 from the information system program 118, the communication control unit 119 generates a message suitable for the information system protocol. The electronic message is sent to the server 103 through the communication unit 113 and the communication line 112. The server 103 sends the sent message to the information system host 102. The response from the information system host 102 is returned to the server 103 through the communication line 111. The server 103 generates an answer that matches the information protocol and returns it to the communication unit 113 through the communication line 112. The communication unit 113 returns it to the communication control unit 119 of the information system program. When the information system processing is completed, the information system program 118 is terminated (S410). When the information system program 117 ends, the accounting system program 114 returns to the active state.
[0020]
When performing the accounting process, an accounting operation is selected from the menu (S406). Taking online processing as an example, line connection with the server 103 is attempted according to a billing protocol. If the line can be connected, the billing program 114 indicates that the transaction is possible and waits for input from the operator. The accounting process is shown in FIG. The operator registers the operator before starting the transaction. The operator registration is performed by setting the ID card held by the operator in the magnetic card reader of the operation unit 105 (S503) and inputting the personal identification number (S504). The ID card and the entered personal identification number are compared (S505), and if they match, the ID registration state is registered (S506). After the operator registration, the screen returns to the selection screen display (S501), and a transaction is selected (payment / withdrawal / inquiry, etc.) (S502). If the deposit transaction is selected, the transaction details (account number, deposit / withdrawal amount, etc.) are input next (S507), and the completion key is pressed at the end of one transaction (S508). When the completion key is pressed, the billing system program 114 performs checks such as operator registration and board approval (S510). The check is performed by comparing with the internal flag of FIG. 10A according to the ID registration condition and the board approval condition in the map format of FIG. If all checks are normal, a message in the format shown in FIG. 11A is generated in the accounting program (S511). Cooperation information is also included in the terminal status information, and now it is “00” in the no cooperation state. The accounting host 101 has a separate process for each transaction, and checks linkage information in each process. In the deposit transaction, the linkage information is checked (S603), but the linkage information is in a no-cooperation state, so the deposit transaction is regarded as a valid transaction (S604 / 605).
[0021]
As described above, accounting and information processing can be performed on a general-purpose platform.
[0022]
The account system program 114 provides a linkage function, and can acquire information held by the account system program / account system host from the information system or OA system. The cooperation control units 116 and 120 have initial setting units 307 and 304 (FIG. 3), respectively. When the accounting program 114 is activated, the initial setting unit 307 of the cooperation control unit informs the data exchange library 301 that the cooperation function is implemented with the name “KANJO”. Next, when the information system program 118 is activated, the initial setting unit 304 declares use of the data exchange library 301. When the information system program uses the linkage function, the request transmission unit 305 of the linkage control unit 305 requests the data exchange library 301 to use the linkage function “KANJO”. The data exchange library 301 notifies the reception unit 308 of the cooperation control unit that there has been a cooperation request. The receiving unit 308 issues a cooperation start request to the transaction control task 203 of the transaction control unit 117 through the state control unit 310, each processing corresponding unit 311, the TLS 313, and the message object 222, and the transaction control task 203 determines whether or not to start the cooperation. Judge and return the result. If the cooperation can be started, the data exchange library transmits a request from the request transmission unit to the reception unit 308 and a notification from the event transmission unit to the reception unit 303. Thus, the cooperation controllers 116 and 120 can exchange data. This state continues until the request transmission unit 305 notifies the data exchange library 301 of the end of cooperation.
[0023]
The linkage function is divided into a message through function and a screen linkage function, and each function cannot be used simultaneously. The message-through function transmits a message specified by the information system / OA system program to the accounting system host 101. The screen linkage function allows the normal operator to specify the operations that the operator performs from the operation unit 105 from the linkage function. Simulate key presses, input / output data to the displayed screen, and register operators that are valid only when the linkage function is in use. I do. Note that the cooperation control unit 116 provides an interface for the cooperation function. The communication control unit 115 and the transaction control unit 117 in the account system program are connected by an interface dedicated to the account system by the message object 222 and the task link library 223, and cannot be directly called from the information system / OA system program.
[0024]
The message-through function is mainly used when a function that is not defined as a transaction of the accounting program 114 is used. When the operator uses the information system program 118, when accessing the customer information of the account host 101 from within the information system program 118, the information system program 118 uses the message through function to access the customer information.
[0025]
FIG. 7 shows a program flow when the message through function is used. The information system program 118 requests permission to use the message through function from the cooperation control unit 120 to the cooperation control unit 116 of the accounting system program 114 (S01). The linkage control unit 116 of the account system program asks the transaction control task 203 of the transaction control unit 117 to check whether the message through function can be used (S02). If there is no transaction in progress and the communication line can be used, the transaction control task 203 notifies the status update library 226 that cooperation is started, and instructs the number task 209 to suppress key input (S04). In addition, the cooperation control unit 116 is permitted to use the message through function. On the other hand, the cooperation control unit 116 that has received permission to use the message through function notifies the information system program 118 that use has been permitted. The information system program 118 determines whether or not cooperation has been started (S05), and if OK, creates a message addressed to the accounting system host 101 (S701), and passes the message to the cooperation control unit 116 of the accounting system program 114 (S702). The cooperation control unit 116 passes a message to the transmission message task 216 of the communication control unit 115 and requests transmission.
[0026]
Upon receiving the request, the transmission message task 216 generates a message shown in the transmission message format example of FIG. 11C (S703). Information necessary for generating the message is acquired from each task of the status update library 226 and the transaction control unit 117. The header portion contains a host identification indicating that the message is addressed to the accounting host, and is set to “79”. The terminal status information includes information indicating the status of the accounting program at the time of message generation, and includes linkage information, which is now “10” during message-through. As described above, the header part and the terminal state information are generated inside the accounting system program and cannot be changed from the information system program 118. The message is sent to the accounting host 101 through the communication line (S704), and is processed by the accounting host 101 (705). In the host process, the linkage information of the terminal status information is also checked (S603, S606). If the customer information is linked and permitted to be referenced, the account host 101 sends the customer information as an answer. Here, if a business that cannot be executed during cooperation, for example, a deposit transaction, is specified, the transaction is invalidated. The reply of the accounting host 101 is sent to the cooperation control unit 119 of the information system program 117 through the communication line 109, the server 103, the communication line 112, the communication unit 113, the communication control unit 115, and the transaction control unit 116 (S706, S707).
[0027]
The screen linkage function is used when a transaction defined in the account program 114 is used from the information system. When an operator is using an information system and wants to inquire account-related customer information during the information system processing, the information system program 118 can acquire information held by the account system using the screen linkage function. FIG. 8 shows a program flow when screen cooperation is used. The cooperation control unit 120 asks the cooperation control unit 116 of the accounting program 114 for permission to use the screen cooperation function (S01). The linkage control unit 116 of the account system program asks the transaction control task 203 of the transaction control unit 117 to check whether the screen linkage function can be used (S02). The transaction control task 203 informs the status update library 226 of the start of cooperation if it is in a state where the account transaction can be executed, and instructs the numeric task 209 to suppress key input (S04). Further, the cooperation control unit 116 is permitted to use the screen cooperation function.
[0028]
On the other hand, the cooperation control unit 116 that has received permission to use the screen cooperation function notifies the information system program 118 that the use has been permitted. The information system program 118 that has received the permission determines whether or not the cooperation has been started (S05), and requests the cooperation control unit 116 to select the inquiry transaction and transmit data used for the inquiry transaction (S801). The cooperation control unit 116 requests data pasting to the screen task 208 via the transaction screen task 205 (S802). Next, the information system program 118 uses the key press simulation to request the cooperation control unit 116 to simulate the completion key (S803). The cooperation control unit 116 requests the numeric task 209 to simulate the completion key. The numeric task 209 performs the same processing as when input from the operation unit 105. In the completion key process, a security check is performed using the map check library 227 (S804). Since the inquiry transaction is possible without operator registration / approval approval, a telegram addressed to the upper station is generated (S805). At this time, since the screen is being linked, it is generated in the format shown in FIG. The linkage information in the terminal status information is “01” during screen linkage. The billing system host 101 checks the message, but it is a valid transaction because it is an inquiry transaction. Even if a deposit transaction is designated, it is repelled by the ID registration / approval check. If the operation ID registration check is passed, the check is made by the check host 101.
[0029]
As described above, the operator can access information held in the accounting system simply by operating the information system. In addition to acquiring accounting information from the information system, the linkage function can be used to transmit accounting data.
[0030]
FIG. 9 shows the flow of processing when transmitting data of the external terminal to the accounting host. When the data of the external terminal 121 is transmitted to the accounting host 101, the external terminal 121 is connected to the general-purpose platform 104, and an operator ID is registered in the accounting system (S901). Next, when the external terminal data transmission process in the account system is selected (S902) and the business cooperation key is pressed (S903), the external terminal control program 122 is executed. The external terminal control program 122 acquires information from the external terminal 121 (S904), and transmits it using the screen-related screen linkage function (S905). In transmitting data of the external terminal 121, an operator registration is requested based on the user information. By changing the registered operator, the transaction data of the external terminal 121 can be matched with the person in charge (S906). After confirming that the operator has already been registered (S907), the designated operator is registered (S908). If the operator is not registered, the operator cannot be registered to prevent unauthorized transactions. Next, the data of the public relations terminal 121 is pasted on the billing screen (S909), and the completion key is simulated (S911). During the external terminal data transmission process, the operator ID registration is checked (S912), and if normal, transmission data is created (S913). The transmission message format is the same as in FIG. When the transmission is finished, the screen cooperation function is finished (S915). Since the original operator registration state is restored at the end of the cooperation (S916), transactions in a state registered with another operator cannot be made. In this way, by using the cooperation function for connection with other terminals, data can be exchanged while maintaining security.
