  The technologies of Patent Documents 1 and 2 described above are not intended for a terminal device of a branch office system, but an authentication technique using a biometric information for releasing the terminal saver system terminal device having a screen saver function. When the terminal device is executing the screen saver function, it cannot be determined whether it is the biological information of the operator or the biological information of the customer, and even if the biological information of the operator is acquired by the biological information acquisition device There may be a problem that the screen saver cannot be canceled and the terminal device cannot be used.

  The present invention provides a screen saver function to a terminal device that performs registration, authentication, etc. of a customer's biometric information with a terminal device handled by a financial institution, and the above-described problem is caused when the biometric information of the operator is used for the release. An object of the present invention is to provide an apparatus and a method suitable for solving the problem.

  To achieve the above-described object, the present invention provides a transaction program for controlling various transaction processes, a user management program for controlling processes for managing user information, a first biological program for controlling processes related to biological information, and a second one. A biometric program is provided in the storage unit. When the screen saver activation time is reached, the control unit of the terminal device determines whether or not the first biometric program is being executed by the transaction program, and if so, cancels the first biometric program, and the user management program and The second biological program is executed to activate the screen saver. If not executed, the user management program and the second biometric program are executed to activate the screen saver.

  According to the present invention, when both a financial institution operator and a customer use a biometric authentication device, screen saver control and transaction processing can be executed while maintaining appropriate security according to the situation.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, exemplary embodiments suitable for the invention will be described in detail with reference to the drawings.

  In this embodiment, a terminal device installed at a counter of a financial institution's sales office and handled by an operator (bank employee, contact person in charge) is taken as an example, and when there is no input to the terminal device, a certain time has elapsed. The terminal device is in a locked state (unoperational), a so-called screen saver function is executed, and the process of releasing the screen saver by biometric authentication (biometric verification) using the biometric information of the operator will be mainly described. If the operator continues to explain the financial product to the customer who visited the counter and the terminal device continues to be in the state of no input, the screen saver of the terminal device is activated. In addition, the biometric information is information unique to the person, and includes various information such as finger veins, palm veins, fingerprints, irises, faces, and the like. .

  FIG. 1 shows a configuration diagram of the above-described terminal device and system. The terminal device 101 is configured by a CRT, a liquid crystal display, and the like, and is configured by a display unit 102 that displays operation guidance, a keyboard, a mouse, and the like, and accepts an input operation. An input unit 103 is provided, and is connected to a biometric authentication device 104 that performs registration and authentication of biometric information. The biometric authentication device 104 is stored in a biometric reader (camera, CCD) 105 that captures (reads) and acquires a user's finger vein pattern as biometric information, card insertion / ejection, a card magnetic stripe, or an IC chip. A card mechanism unit 106 having a function of reading and writing data is provided.

  Here, bank operations and transaction processing using the terminal device 101 will be described. For this process, the transfer form brought in by the customer is automatically recognized by a recognition mechanism (not shown) provided in the terminal device 101, and the transfer amount is settled by obtaining the transfer amount, or the seal stamp stamped on the form is registered in the server. The terminal device 101 executes various transaction processes such as a seal collation process for confirming that the customer who brought the form by collating with the registered seal stamp is valid. These transaction processes are based on items operated by the operator via the input unit 103 and input data from operation guidance corresponding to various transactions displayed on the display unit 102 of the terminal device 101. Go. Further, the transactions that can be executed by the terminal device 101 include transactions that use the biometric authentication device 104. For example, there are a case where a customer opens a bank account and a case where a customer performs a withdrawal transaction with an amount requested by the customer. These examples will be briefly described.

  As an example of using the biometric authentication device 104 when opening an account, there is biometric information registration processing for registering customer biometric information in an IC card (also simply referred to as a card). At this time, the operator biometrically authenticates a new card 110. It is inserted into the card mechanism unit 106 of the apparatus 104, the biometric information of the customer is acquired by the biometric reader 105, stored in the card 110 in the card mechanism unit 106, and the registration process is completed. In addition, the operator performs a predetermined operation on the terminal device 101 and issues an account number of the customer to open an account.

  Further, as an example in which the biometric information of the customer is registered in the card and the withdrawal transaction is performed using the biometric information, the operator inserts the card 110 brought by the customer into the card mechanism unit 106 of the biometric authentication device 104, On the other hand, the biometric information of the customer is acquired by the biometric reader 105, and the biometric information stored in the card 110 in advance in the card (the biometric authentication apparatus may be authenticated) and the new biometric information acquired by the biometric reader 105 are stored. The person is verified by collating with the correct biometric information, and the withdrawal requested by the customer is permitted.

  FIG. 2 is a block diagram of the terminal device 101.

  The terminal device 101 transmits and receives data to and from the control unit 201 that controls the entire terminal device 101, the display unit 102, the input unit 103, a memory 203 that stores programs, a storage unit 208 that stores various data, and the biometric authentication device 104. The communication unit 209 is provided.

  The memory 203 also includes a transaction program 204 that controls various transaction processes, a user management program 205 that controls processes for managing user information, a first biological program 206 and a second biological program 207 that control processes related to biological information. , Remember. These programs are application software executed by the control unit 201 including the CPU 202 and the memory 203.

  For example, the processing executed by the transaction program 204 includes biometric registration processing for registering customer biometric information in the card 110, withdrawal transaction processing using biometric authentication for customer identification, balance inquiry processing, and the like. Examples of processing executed by the user management program 205 include screen saver activation and cancellation, and password verification. The first biometric program 206 and the second biometric program 207 perform biometric information registration and verification processing, respectively. The former is executed during customer transactions, and the latter is executed during operator operation.

  Therefore, the first biological program 206 is a program that is activated together with the transaction program 204, and the second biological program 207 is a program that is activated together with the user management program 205.

  More specifically, the first biometric program 206 is executed if there is a process using the biometric authentication device 104 while the transaction program 204 is being executed on the terminal device 101 in order for the operator to guide the customer. When the terminal device 101 activates the screen saver, the user management program 205 is executed. At this time, since the biometric authentication device 104 is used to cancel the screen saver, the second biometric program 207 is also executed simultaneously with the activation of the user management program 205.

  The biometric authentication device 104 includes a control unit 211 that controls the entire biometric authentication device, a biometric reader 105, a card mechanism unit 106, and a communication unit 212 that transmits and receives data to and from the outside. The terminal device 101 and the biometric authentication device 104 may be collectively referred to as a terminal device.

  FIG. 3 is an example of a data table held in the storage unit 208. The system user ID, authority, authentication method, biometric information, and password are stored in association with each other. For system users, “administrators” who have strong authority, such as being able to rewrite all information, “users” targeting general operators, and temporary visitors use the terminal device 101 Prepare "visitors" to use for For example, the “administrator” has a user ID of 0000, an authority of Administrator, an authentication method of password + biometric authentication, biometric information of AAA, and a password of 1234. The general operator has a user ID of 0001, an authority of Users, an authentication method of password + biometric authentication, biometric information of BBB, and a password of 2345. The visitor has a user ID of 0100, an authority of Guest, an authentication method of password + biometric authentication, no biometric information, and a password of 4567.

  Further, as shown in the database of FIG. 3, the administrator, the user, and the visitor are set in advance in descending order of authority level. If it is an administrator with administrator authority, it may be configured to allow a special operation such as forcibly logging off others.

  Next, the operation of each unit in FIG. 1 will be described based on the flowchart in FIG.

  When the input unit 103 detects an input, the control unit 201 of the terminal device 101 initializes a timer (step 401) and starts measuring an uninput time (step 402). When the non-input time reaches the set time for starting the screen saver stored in the storage unit 208 (step 403), the execution state of the first biometric program 206 is checked. As described above, execution of the first biometric program 206 indicates that the transaction program 204 is also executed.

  It is determined whether or not the first biometric program 206 is executed (step 404). If it is executed, the first biometric program 206 is stopped (cancelled) (step 405) and the user management program 205 is executed. At the same time, the second biological program 207 is executed. This activates a screen saver on the display unit 102 (step 406). Thus, when the screen saver is activated, the second biometric program 207 for controlling the operation of the biometric authentication device 104 used to release the screen saver is also activated.

  Here, the reason for stopping the first biometric program 206 in step 405 will be described. A configuration in which a plurality of programs for controlling the biometric authentication device 104 exists is not preferable because it is difficult to know what operation the biometric authentication device 104 should perform. Therefore, as long as the second biometric program 207 is executed in step 405, the first biometric program 206 executed so far is stopped.

  On the other hand, if the first biometric program 206 is not executed in step 404, the user management program 205 is executed and the second biometric program 207 is executed. This activates the screen saver (step 406). Here, since the first biometric program 206 is not executed, it is possible to execute the second biometric program 207 without any trouble.

  After starting the screen saver, the control unit 201 of the terminal device 101 enters an input standby state waiting for input from the operator.

  Then, when the control unit 201 of the terminal device 101 detects an input by the input unit 103 (step 407), the control unit 201 displays a screen G01 (ID and password input screen) for guiding the input of ID and password on the display unit 102 (step 407). 408). The operator inputs the ID and password to the input unit 103 according to the guidance on the screen G01.

  When the input unit 103 detects an input, the control unit 201 of the terminal apparatus 101 determines whether the ID and password in the data table held in the storage unit 208 illustrated in FIG. 3 match the input ID and password. Is determined (step 409).

  Here, it is assumed that the user 1 who is a valid operator inputs “0001” as the ID and “2345” as the password using the input unit 103. Since the input ID and password are stored (registered) in advance in the data table, they are “match”.

  Further, it is assumed that a suspicious person inputs “0001” as an ID and “5555” as a password using the input unit 103. Since the input ID and password are not stored (registered) in advance in the data table, they do not match.

  If they do not match in step 409, the process returns to step 408 to display the screen G01. If they do not match, several causes are considered as follows, and guidance corresponding to the cause is displayed on the display unit 102.

  (1) When the cause is unregistered ID. At this time, the display unit 102 displays that “the input ID is not registered. Please input the ID and password again”.

  (2) When the cause is a password mismatch (ID was registered). At this time, the display unit 102 displays the message “The password has been entered incorrectly. Please enter the ID and password again”.

  When they match in step 409, the control unit 201 of the terminal apparatus 101 displays a screen G02 for guiding biometric authentication on the display unit 102 (step 410). Note that the screen G02 is a screen for outputting guidance to hold the living body over the living body reader 105. The operator holds a finger over the biometric reader 105 according to the guidance on the screen G02.

  Next, the control unit 201 of the terminal device 101 reads the information of the finger held over the biometric reader 105 and executes biometric authentication (step 411). Specifically, whether the biometric information (finger image) acquired by the biometric reader 105 matches the biometric information (finger image) corresponding to the ID of the data table stored in the storage unit 208 (biometric authentication). (Step 412).

  Here, for example, it is assumed that the biometric information acquired by the biometric reader 105 is “BBB”. Since the biometric information of the person whose ID is “0001” is stored as “BBB” in the data table, it becomes “match (biometric authentication succeeded)”.

  Further, it is assumed that the biometric information acquired by the biometric reader 105 is “BBA”. Since the biometric information of the person whose ID is “0001” is stored as “BBB” in the data table, “not match (biometric authentication failed)”.

  If they do not match at step 412 (the biometric authentication has failed), the process returns to step 410 to display the screen G02.

  When they match in step 412 (the biometric authentication is successful), the screen saver is released (step 413).

  Note that when the first biometric program 206 is temporarily stopped in step 405, the information of the contents processed by the control unit 201 of the terminal device 101 until then is deleted. Then, after canceling the screen saver in step 413, the transaction by the transaction program is restarted from the beginning.

  According to this flowchart, even when the operator is instructing the customer about biometric registration processing and biometric authentication processing including use of the biometric authentication device 104, the screen saver can be reliably activated. Therefore, when an operator is instructing a customer to make a transaction using the biometric authentication device 104, when the operator switches to another operator, the screen saver is surely secured when there is no input time to the input unit 103. Since it can be activated, it is highly effective in terms of security. Of course, even when the operator does not provide guidance to the customer regarding biometric registration processing including use of the biometric authentication device 104 or biometric authentication processing, the screen saver can be reliably activated.

  Next, a second embodiment will be described based on the flowchart of FIG.

  When the input unit 103 detects an input, the control unit 201 of the terminal device 101 initializes a timer (step 501), and starts measuring a non-input time (step 502). When the non-input time reaches the set time for starting the screen saver stored in the storage unit 208, the activation state of the transaction program 204 is checked (step 503).

  It is determined whether or not the first biological program 206 is executed (step 504). If it is executed, the transaction flag stored in the storage unit 208 is set to ON (step 505), and the user The management program 205 is executed. This activates a screen saver on the display unit 102 (step 507). Here, the second biometric program 207 is not executed because biometric authentication is not used to cancel the screen saver when the transaction flag is ON.

  On the other hand, if the first biometric program 206 is not executed in step 504, the transaction flag stored in the storage unit 208 is set to OFF (step 506), the user management program 205 is executed and the first 2 The biological program 207 is executed. This activates the screen saver (step 507).

  After starting the screen saver, the control unit 201 of the terminal device 101 enters an input standby state waiting for input from the operator.

  Then, when the control unit 201 of the terminal device 101 detects an input by the input unit 103 (step 508), the control unit 201 displays a screen G01 (ID and password input screen) for guiding the input of ID and password on the display unit 102 (step 508). 509). The operator inputs the ID and password to the input unit 103 according to the guidance on the screen G01.

  Next, when the input unit 103 detects the input of the ID and password, the control unit 201 of the terminal device 101 matches the input ID and password with the ID and password of the data table held in the storage unit 208. (Step 510).

  If they do not match in step 510, the process returns to step 509 to display the screen G01. If they do not match, as shown in the first embodiment, several causes are conceivable, and guidance corresponding to the cause is displayed on the display unit 102. When they match in step 510, the control unit 201 of the terminal device 101 reads the transaction flag in the storage unit 208. It is determined whether or not the transaction flag is set to ON (step 511), and if it is ON, the screen saver is canceled without executing biometric authentication (step 515).

  On the other hand, if the transaction flag is OFF, the process proceeds to the biometric authentication process. The control unit 201 of the terminal device 101 displays a screen G02 for guiding biometric authentication on the display unit 102 (step 512), and the operator causes the biometric reader 105 to display the screen G02 and hold the living body over the biometric reader 105. Hold your finger.

  The control unit 201 of the terminal device 101 reads the information of the finger held over the biometric reader 105 and executes biometric authentication (step 513). Specifically, the biometric information is acquired by the biometric reader 105, and it is determined whether or not the obtained biometric information matches the biometric information corresponding to the ID of the data table held in the storage unit 208 (step 514).

  If they do not match in step 514, the process returns to step 512 to display the screen G02, and if they match in step 514, the screen saver is canceled (step 515).

  Note that when the transaction flag is set to ON in step 505, the information of the contents processed by the control unit 201 of the terminal device 101 until then is stored in the storage unit 208 without being deleted. Then, after canceling the screen saver in step 515, the transaction by the transaction program is resumed from the stage before starting the screen saver based on the information stored in the storage unit 208. Thus, although the transaction is interrupted by the activation of the screen saver, the transaction can be resumed from the state before the interruption, so that the operability for the operator is improved.

  According to this flowchart, when the operator is instructing the customer about biometric registration processing and biometric authentication processing including the use of the biometric authentication device, the screen saver is activated using the password verification as a cancellation condition without using biometric authentication. can do. When the above guidance is not provided, the screen saver can be activated using biometric authentication and password verification as cancellation conditions.

  Therefore, there is an effect of realizing high-security screen saver control in a state where there is no transaction using the biometric authentication device 104. In addition, when there is a transaction using the biometric authentication device 104, even if a transaction such as a withdrawal transaction or account opening is interrupted and the transaction state is discarded, the screen saver is surely activated. Because it can, it can achieve the same level of security as before.

  Up to this point, the features of the first and second embodiments are summarized.

  In the first embodiment, if there is no input to the input unit 103 even after a predetermined time has elapsed, the terminal device 101 determines whether or not the first biometric program 206 is being executed. When the first biological program 206 is being executed, the first biological program 206 is temporarily stopped and the screen saver is activated. On the other hand, when the first biometric program 206 is not activated, the screen saver is automatically activated. After that, password verification and biometric authentication are used to cancel the screen saver.

  That is, it can be said that the first embodiment is a flow that uses the biometric authentication device 104 preferentially for the activation of the screen saver over the transaction guidance.

  In the second embodiment, the terminal device 101 determines whether or not the first biological program 206 is being executed if there is no input to the input unit 103 even after a predetermined time has elapsed. Then, when the first biometric program 206 is being executed, the transaction flag 204 is set to “ON” and the screen saver is activated. On the other hand, when the first biometric program 206 is not activated, the transaction flag is set to “OFF” and the screen saver is automatically activated. After that, if the transaction flag is set to “ON”, the screen saver is canceled only by password verification without using biometric authentication. If the transaction flag is set to “OFF”, identity verification is performed by biometric authentication and password verification. Cancel the screen saver after

  That is, it can be said that the second embodiment is a flow for activating the screen saver by effectively utilizing the transaction flag and determining whether or not the biometric authentication using the biometric authentication device 104 is used for canceling the screen saver.

  Up to this point, an example in which there are two biological programs, the first biological program and the second biological program, has been described, but in the following, an aspect in which there is one biological program will be described. When the process proceeds to the process of using the biometric authentication device 104 while the transaction program 204 is being executed, the biometric program is executed, and the same biometric program is executed when the user management program 205 is executed to activate the screen saver. The biological program is instructed to execute one of the transaction program 204 and the user management program 205. In other words, both the transaction program 204 and the user management program 205 cannot execute the biometric program at the same time.

  This will be described on the flowchart of FIG. 4. In step 404, “Is the first biometric program being executed?” Is changed to “A transaction program is being executed and a biometric program is being executed?” “Stop the first biometric program” in Step 405 is changed to “Stop the trading program”. That is, it is determined whether the transaction program 204 is executing a biometric program in order to use the biometric authentication device 104. If the transaction program 204 is being executed, the transaction program 204 is stopped and the user management program 205 is executed. Then, the user management program 205 executes a biometric program for using the biometric authentication device 104.

  On the other hand, this will be described on the flowchart of FIG. 5. In step 504, “Is the first biological program being executed?” Is changed to “Is the transaction program being executed and the biological program being executed?” . That is, it is determined whether the transaction program 204 is executing the biometric program in order to use the biometric authentication device 104. If the transaction program 204 is being executed, the transaction flag is set to ON and the transaction program 204 is executed while the user is running. The management program 205 is executed. In this flowchart, since the biometric authentication is not performed when the transaction flag is set to ON, the user management program 205 does not execute the biometric program.

  Thus, even when there is only one biometric program, it has high security as in the case where there are two biometric programs. And there is an advantage that it is not necessary to create two biometric programs as in the first and second embodiments.

  In the above-described first embodiment, and in the second embodiment, when the transaction flag is set to OFF, biometric authentication is performed when the screen saver is released. However, for reasons such as finger injury or biometric authentication device 104 failure. When biometric authentication is not possible, the screen saver may be canceled only by password verification by skipping biometric authentication by a predetermined key operation or other means.

  Up to this point, the configuration has been described in which the control unit 201 reads various information from the data table of the storage unit 208 and executes processing. However, such information may be stored in a medium such as an IC card or a database of a server, and the control unit 201 may read various information from the medium or the server and execute processing. When the user ID is held on the medium, the user ID can be read from the medium, so that it is possible to save the operator and the like from inputting using the input unit 103.

  In the case where the information is stored in the database of the server, personal information such as biometric information can be collectively managed, so that management is easier than a configuration in which personal information is stored in the terminal device 101. In financial institutions, the operator and the terminal device 101 are generally arranged at a plurality of windows, and the operator does not always use the same terminal device 101, and the terminal device 101 to be used changes depending on time and circumstances. Therefore, it is preferable to store biometric information of all operators that may be used in the terminal device 101. If biometric information is stored in a plurality of places, the risk of information leakage increases. Because it ends up.

  When the personal information is collectively managed by the server, the communication unit 209 is used to transmit and receive biometric information stored in advance with the server each time the terminal device 101 collates biometric information. That's fine.

  As described above, according to the present invention, when both an operator of a financial institution and a customer use a biometric authentication device, screen saver control and transaction processing can be executed while maintaining appropriate security according to the situation.
