  Next, a description will be given of a first embodiment of a process for reducing the operation performance according to the number of times of password input by the multifunction machine 1 and the data processing apparatus according to an embodiment of the present invention. FIG. 4 is a flowchart showing a first embodiment of a process for reducing the operation performance according to the number of times of password input.

  When the ID information and password (operation permission password) stored in advance in the security information storage unit 1702 are input from the operator, the multi-function device 1 causes the operator to execute the operations of each unit of the multi-function device 1. It comes to allow. First, the control unit 103 causes the display unit 473 to display a message indicating that the operation performance of the multifunction device 1 is degraded when incorrect ID information or a password is input by the operator (S1). For example, the control unit 103 causes the display unit 473 to display a specific message that suggests a decrease in performance of the predetermined operations as shown in the above (1) to (6).

  Subsequently, the control unit 103 causes the display unit 473 to display a message that prompts the operator to input ID information (S2). When the input of ID information by the operator is accepted by the operation unit 47 (YES in S3), the authentication unit 101 indicates that the input ID information is regular ID information stored in the security information storage unit 1702. Whether or not (S4).

  When the input of ID information from the operator is not accepted by the operation unit 47 (NO in S3), and when the authentication unit 101 determines that the input ID information is not regular ID information (S4). NO), the process returns to S2.

  On the other hand, when the authentication unit 101 determines that the input ID information is legitimate ID information (YES in S4), the control unit 103 displays a message prompting the operator to input a password. It is displayed on 473 (S5).

  Thereafter, when an input of a password by the operator is accepted by the operation unit 47 (YES in S6), the authentication unit 101 associates the input password with the ID information determined to be legitimate in S4 and performs security. It is determined whether the password is a legitimate password stored in the information storage unit 1702 (S7).

  If the authentication unit 101 determines that the input password is not a legitimate password (NO in S7), the counter 104 counts up the number of times the password is input for the input ID information ( S8). After counting up the number of times of password input by the counter 104, the control unit 103 determines whether or not the count value (number of times of password input) counted by the counter 104 is equal to or greater than a predetermined first value ( S9). The first value is a value (eg, 3) arbitrarily set by the user, and is stored in a memory (not shown) that is a part of the control unit 100.

  If the count value of the counter 104 is not equal to or greater than the first value (NO in S9), the process returns to S5, and the control unit 103 again displays the password for the input ID information on the display unit 473. Is displayed on the display unit 473 (S5). The operator is prompted to enter the password again.

  When the count value of the counter 104 has reached the first value (YES in S9), the control unit 103 causes the display unit 473 to display a message indicating that the operation performance of the multifunction device 1 is degraded (S10). ). In this case, the control unit 103 causes the display unit 473 to specifically display each operation as described in the above (1) to (6) in which the performance decreases. And after this display, the control part 103 performs the process which reduces the performance about predetermined operation | movement (operation | movement as shown to said (1)-(6)) (S11). The control unit 103 sets a flag indicating that the operation is performed with a reduced performance when the regular password is input to the operation unit 47 by the next operator (flag = 1).

  If the authentication unit 101 determines in S7 that the input password is a legitimate password (YES in S7), the control unit 103 determines whether or not the flag is set ( S12) When the flag is set (“1” in S12), the operation of the multifunction device 1 is permitted with the performance of the predetermined operation being lowered (S13). That is, the control unit 103 sets the multifunction device 1 to operate only in a state where the performance of a predetermined operation is lowered. Further, when the flag is not set (“0” in S12), the control unit 103 permits the operation of the multifunction device 1 in a normal state in which the operation performance is not deteriorated (S14). That is, the control unit 103 sets the multifunction device 1 in an operable state in a normal state in which the operation performance is not deteriorated.

  As a result, against unauthorized persons who repeatedly input an incorrect password to the operation unit 47, the use of the multifunction device 1 with full operation performance is restricted, and security for operating the multifunction device 1 is ensured. However, it is convenient for an appropriate operator to operate the apparatus by avoiding a situation in which the multifunction device 1 is not allowed to operate at all, and an appropriate operator who has input an incorrect password. Is improved. In addition, the maintenance person or an appropriate operator can adjust which of the security level and convenience for use of the apparatus with complete operation performance is improved by changing the first value. .

  Next, a description will be given of a second embodiment of a process for reducing the operation performance in accordance with the number of times of password input by the multifunction machine 1 and the data processing apparatus according to an embodiment of the present invention. FIG. 5 is a flowchart showing a second embodiment of a process for reducing the operation performance in accordance with the number of password inputs. The description of the same processing as that of the first embodiment shown in FIG. 4 is omitted.

  In the second embodiment, when a second password for performance restoration (hereinafter referred to as a restoration password) different from the password for permitting operation is input from the operator to the operation unit 47, the control unit 103 The state of the MFP 1 whose operating performance has been lowered is returned to the state in which the normal operation is performed.

  This will be described with reference to FIG. When the input of the password by the operator is accepted by the operation unit 47 (YES in S26), the authentication unit 101 determines whether the input password is a regular restoration password or a regular operation permission password. Is determined (S27, S28). The authentication unit 101 confirms that the input password matches the restoration password stored in the security information storage unit 1702 in association with the ID information determined to be legitimate in S24. Is a legitimate recovery password.

  When the authentication unit 101 determines that the input password is a regular restoration password (YES in S27), the control unit 103 returns the state of the MFP 1 whose operating performance has been lowered to the original normal state. (S35), and the operation of the multifunction device 1 is permitted in this state (S36). In S <b> 35, the control unit 103 sets the flag, which is an index as to whether or not to operate the multifunction device 1 by reducing the performance, to 0.

  On the other hand, if the authentication unit 101 determines that the input password is not a regular restoration password (NO in S27), whether the input password is a regular operation permission password or not. It is determined whether or not (S28). Henceforth, the process of S29 thru | or S34 and S36 is the same as that of 1st Embodiment.

  According to the second embodiment, even after the operation performance of the multifunction device 1 is lowered, when the restoration password is input by the operator, the operation performance of the multifunction device 1 is lowered. Therefore, the proper operator can use the original password for permission of operation and the recovery password properly to make the device in a state where the operation performance is lowered. You can choose whether to restore or restore to the original state.

  Next, a description will be given of a third embodiment of a process for reducing the operation performance in accordance with the number of password inputs by the multifunction machine 1 and the data processing apparatus according to an embodiment of the present invention. FIG. 6 is a flowchart showing a third embodiment of a process for reducing the operation performance in accordance with the number of password inputs. Note that description of the same processing as in the first and second embodiments shown in FIGS. 4 and 5 is omitted.

  In the third embodiment, the control unit 103 increases the degree of deterioration of the operation performance of the multifunction device 1 in accordance with an increase in the number of passwords input by the operator by mistake.

  A description will be given with reference to FIG. In the third embodiment, when the count value (password input count) counted by the counter 104 has reached the first value (YES in S60), the control unit 103 further determines that the count value of the counter 104 is It is determined whether a predetermined second value larger than the first value has been reached (S61). The second value is a value arbitrarily set by the user (for example, 50 or the like), and is stored in a memory (not shown) that is a part of the control unit 100.

  When the count value of the counter 104 has not reached the second value (NO in S61), the control unit 103 causes the display unit 473 to display a message indicating that the operation performance of the multifunction device 1 is degraded. (S62) A process for reducing the performance of a predetermined operation by a predetermined amount is performed (S63). For example, after the count value of the counter 104 reaches the first value, the control unit 103 increases the count value by 1 (every time the password is input once by the operator). The copy operation, facsimile operation, scanner operation, and printer operation that can be performed by the machine 1 are prohibited one by one. (8) The number of prints in the storage unit 40 during the copy operation, facsimile operation, and printer operation is limited or the printing speed. (9) Decrease the document reading speed of the document reading unit 5 during the copy operation, facsimile operation, and scanner operation by a predetermined rate. (10) Display on the display unit 473 (11) The touch panel counter of the button displayed on the display unit 473 is reduced by a predetermined number of contents such as an operation guide to be performed and a button for receiving a function execution instruction. The response speed is decreased by a predetermined amount, (12) the buttons displayed on the operation unit 47 are not reacted one by one, and so on.

  On the other hand, when the count value of the counter 104 has reached the second value (YES in S61), the control unit 103 returns the process to S55. In other words, the control unit 103 does not perform a process of reducing the operation performance of the multifunction device 1 when the number of times the password is input by the operator reaches a predetermined number. For example, if an unauthorized person inputs a password a great number of times in order to input a regular password, in the third embodiment, the amount of performance reduction in the operation performance reduction processing of the multifunction device 1 by the control unit 103 is reduced. As the number of times the password is entered increases, the disadvantage to the appropriate operator becomes excessive, so that the operability of the appropriate operator should be ensured when an unauthorized person enters the password many times. Yes.

  In S57, if the authentication unit 101 determines that the restoration password received by the operator from the operation unit 47 is valid (YES in S57), the control unit 103 determines the MFP 1 in advance. The obtained operation performance is returned to a state close to the original normal operation performance by a predetermined amount (S64). That is, by repeating the processing of S57, S64, S67, S69, and S70, the amount of restoration of the operation performance of the multifunction device 1 is increased in accordance with the increase in the number of times of inputting the restoration password.

  It is preferable that the operation performance restoration amount per one regular restoration password input in S64 is the same as the operation performance degradation amount of the multifunction device 1 per one entry of the incorrect operation permission password in S63. However, different amounts may be used. The control unit 103 repeats the predetermined amount of restoration, and sets the flag to 0 when the operation performance of the multifunction device 1 returns to the original normal operation performance.

  Then, the control unit 103 determines whether or not the flag is set (S67). If the flag is set (“1” in S67), the operation performance does not return to the original state in this way. However, the display unit 473 displays a message for prompting the operator to input an instruction as to whether or not to operate the MFP 1 that has been restored to some extent (S69). Here, when an instruction (for example, a copy execution start instruction) for operating the multifunction device 1 is input to the operation unit 47 by the operator (YES in S70), the control unit 103 determines the operation performance state at this time point. The operation of the MFP 1 is permitted to the operator who has input the restoration password (S71). When the operator does not input an instruction to operate the multifunction device 1 (NO in S70), the control unit 103 returns the process to S55. That is, the control unit 103 sets the multifunction machine 1 in a state where the operator can input the restoration password or the operation permission password again. As a result, the operator performs printing or the like by the multifunction device 1 with the operation performance at the time when the regular restoration password is input, or inputs the restoration password to the operation unit 47 again and further restores the operation performance. It is possible to select whether to perform printing or the like by the multifunction device 1.

  As a result, after the password input count reaches the predetermined first value, the operation performance of each part of the device gradually deteriorates as the number of illegal password input increases, so repeat the process over and over again. For those who are likely to be unauthorized persons who enter passwords, security can be increased by increasing the amount that reduces the performance of each part of the device, and it is assumed that the number of incorrect password entries is small. For an appropriate operator, it is possible to increase the convenience when operating the apparatus by reducing the amount by which the operation performance of each part of the apparatus is reduced. Further, the operator can adjust the degree to which the device is restored to the original state by adjusting the number of times the second password for performance restoration is input.

  In addition, after the number of times the password has been input reaches a predetermined second value that is greater than the first value, the process of reducing the operation performance of each part of the device is stopped, so that the error is repeated many times. When a password is entered, the operation performance of each part of the device is lowered to some extent to increase security against unauthorized persons, while the operation performance of each part of the device is ensured after the number of times the password is entered reaches the second value. As a result, it is possible to ensure the ease of use of the device for an appropriate operator.

  Next, an automatic teller machine and an automatic teller system according to an embodiment of the present invention will be described. FIG. 7 is a block diagram showing a schematic configuration of an automatic teller system according to an embodiment of the present invention. In addition, the said automatic teller machine and an automatic teller machine are an example of the electronic device which concerns on this invention, an automatic teller machine, and an automatic cash payment system. The description of the same configuration as that of the multifunction machine 1 described above as an embodiment of the present invention will be omitted.

  The automatic teller machine 500 includes an automatic teller machine 200 and a host computer 300.

  The automatic teller machine 200 is a device (ATM (Automatic Teller Machine)) used for depositing / withdrawing deposits and the like in a financial institution, etc., and a host computer managed by the financial institution to manage the deposit / withdrawal of the depositor It is connected to 300 with a dedicated line. The automatic teller machine 200 includes a data transmission / reception unit 201, a control unit 202, a display unit 203, a cash storage unit 207, a recording unit 205, and a deposit / withdrawal unit 204.

  The data transmission / reception unit 201 transmits / receives information related to deposit / withdrawal of deposits through a dedicated line or the like with a host computer managed by a financial institution or the like. For example, when ID information and a personal identification number (password) are input to the operation unit 47 from a depositor who wishes to operate the automatic teller machine 200 (for example, a deposit withdrawal operation), the input is performed. The ID information and the password are transmitted to the host computer 300, and information indicating whether or not the transmitted ID information and password are authentic is received.

  The input of ID information from the depositor is performed when the depositor inserts a cash card into a card reader unit (magnetic recording medium reading unit) that forms part of the operation unit 206, and the card reader unit is attached to the cash card. ID information is read from the magnetic recording medium. The personal identification number is input to the automatic teller machine 200 by the depositor operating a touch panel function or a keyboard provided on the display unit 203 including an LCD (Liquid Crystal Display) that forms part of the operation unit 206. The

  The control unit 202 controls operation of the automatic teller machine 200 as a whole.

  The deposit / withdrawal unit 204 is a mechanism for delivering cash to a depositor who operates the automatic teller machine 200. The recording unit 205 prints a usage statement provided to the depositor. The cash storage unit 207 is a mechanism for storing cash that is transferred to and from the depositor.

  The host computer 300 includes a data transmission / reception unit 305, a control unit 306, an authentication unit 307, a data storage unit 308, and a counter 309. The data transmission / reception unit 305 transmits / receives various information to / from the automatic teller machine 200 via a dedicated line. It receives and returns information indicating whether or not the transmitted ID information and personal identification number are authentic. Note that the authentication unit 307 determines whether the ID information and the password are valid.

  The control unit 306 controls the overall operation of the host computer 300. When the data transmission / reception unit 305 receives the ID information and password from the automatic teller machine 200, the authentication unit 307 receives the received ID information and the ID information stored in the security information storage unit 3082. (That is, whether or not the input ID information is properly registered). Further, when the authentication unit 307 determines that the ID information is valid, whether or not the input password number matches the password stored in the security information storage unit 3082 (that is, the input password is input). Whether or not the personal identification number is properly registered).

  When the withdrawal limit restoration password is input from the depositor to the operation unit 206 of the automatic teller machine 200, the data transmission / reception unit 201 transmits the withdrawal limit restoration password to the host computer 300. It has become. When the data transmission / reception unit 305 of the host computer 300 receives the withdrawal limit restoration password, the authentication unit 307 associates the received withdrawal limit restoration password with the ID information determined to be normal. Whether or not the withdrawal limit restoration password stored in the security information storage unit 3082 matches (that is, whether or not the entered withdrawal limit restoration password is properly registered). Judging.

  When the authentication unit 307 determines that the combination of the ID information and the personal identification number is not valid, the control unit 306 sets the withdrawal limit for the depositor having the ID information by a predetermined amount. (For example, 10,000 yen) The withdrawal limit information for the depositor having the ID information stored in the customer information storage unit 3081 is rewritten to the reduced withdrawal limit.

  The data storage unit 308 includes a customer information storage unit 3081 and a security information storage unit 3082. The customer information storage unit 3081 stores information on the deposit amount, deposit / withdrawal details, and withdrawal limit for each depositor. The security information storage unit 3082 stores ID information about each depositor and a personal identification number associated with each ID information. Further, the security information storage unit 3082 stores a withdrawal limit restoration password for each depositor in association with the ID information of the operator.

  The counter 309 counts the number of times the ID number is input to the operation unit 47 by the depositor after the ID information is input to the operation unit 47 of the automatic teller machine 200 by the depositor. The counter 309 may be provided on the automatic teller machine 200 side. In that case, the counter 309 counts the number of input of the personal identification number input to the operation unit 47 of the automatic teller machine 200, and the data transmission / reception unit 201 transmits the count value to the host computer 300.

  Withdrawal processing by the automatic teller machine 200 will be described. FIG. 8 is a flowchart showing a withdrawal process by the automatic teller machine 200.

  In the automatic teller machine 200, the control unit 2022 causes the display unit 203 to display a message indicating that the withdrawal limit is reduced when incorrect ID information or a password is input (S81).

  Subsequently, the control unit 103 causes the display unit 203 to display a message prompting the depositor to insert a cash card (S82). When the cash card is inserted into the card reader unit of the operation unit 47 by the operator and the ID information is read by the card reader unit (YES in S83), the data transmitting / receiving unit 201 sends the input ID information to the host computer 300. Send.

  In the host computer 300, the data transmission / reception unit 305 receives the input ID information. The authentication unit 307 determines whether or not the received ID information is regular ID information stored in the security information storage unit 3082 (S84). The data transmission / reception unit 305 transmits information indicating whether or not the received ID information is authentic to the automatic teller machine 200. If there is no input of ID information (NO in S83) and if the authentication unit 307 determines that the input ID information is not legitimate ID information (NO in S84), an automatic teller machine The control unit 2021 of 200 returns the process to S82.

  When the input ID information is determined to be legitimate ID information by the authentication unit 307 of the host computer 300 (YES in S84), the data transmitting / receiving unit 305 displays information indicating that fact to an automatic teller machine. When the data transmission / reception unit 201 of the automatic teller machine 200 receives the information, the control unit 2021 of the automatic teller machine 200 displays a message prompting the depositor to input a personal identification number. It is displayed on 473 (S85).

  When the input of the personal identification number by the depositor is accepted by the operation unit 206 (YES in S86), the data transmitting / receiving unit 201 transmits information input from the depositor as the personal identification number to the host computer 300. In the host computer 300, the data transmission / reception unit 305 receives the information, and the authentication unit 307 first determines whether the information is a regular withdrawal limit restoration password (S87).

  If the authentication unit 307 determines that the information is not a regular withdrawal limit restoration password (NO in S87), the authentication unit 307 continues to identify the ID information that the information has been determined to be normal in S84. It is determined whether or not the password is a legitimate password stored in the security information storage unit 3082 (S88).

  Here, when the authentication unit 307 determines that the input information is not a regular password (NO in S88), the counter 309 indicates the number of times the password is input for the input ID information. Count up (S89). After counting up the number of times the PIN number is input by the counter 309, the control unit 306 determines whether or not the count value (password input count) counted by the counter 309 is equal to or greater than a predetermined first value. (S90). The first value is a value (for example, 3) that is arbitrarily set by an administrator of the automated teller machine 500, and is stored in a memory (not shown) that is a part of the control unit 306. ing.

  When the count value of the counter 309 is not equal to or greater than the first value (NO in S90), the data transmitting / receiving unit 305 of the host computer 300 displays information indicating that the count value is not equal to or greater than the first value. To the automatic teller machine 200. When the data transmission / reception unit 201 of the automatic teller machine 200 receives the information, the control unit 2021 returns the process to S85, and again displays a message prompting the depositor to input the password again on the display unit 203. It is displayed on the display unit 203 (S85). The operator is asked to input the password again.

  When the count value of counter 309 has reached the first value (YES in S90), control unit 306 further determines that the count value of counter 309 is greater than the first value. It is determined whether the second value has been reached (S91). The second value is a value arbitrarily set by the user (for example, 20), and is stored in an unillustrated memory that is a part of the control unit 306.

  When the count value of the counter 309 has reached the second value (YES in S91), the data transmission / reception unit 305 displays information indicating that the count value is equal to or greater than the second value in cash automatic The data is transmitted to the deposit machine 200. When the data transmitting / receiving unit 201 of the automatic teller machine 200 receives the information, the control unit 2021 returns the process to S85 based on the reception of the information. For example, when an unauthorized person inputs a personal identification number a great number of times in order to enter a regular password, the amount of withdrawal of the withdrawal limit by the control unit 306 of the host computer 300 increases the number of personal identification number input. Accordingly, the depositor becomes able to withdraw only a small amount of the deposit or cannot withdraw at all. Therefore, the convenience of the depositor is ensured when the fraudster inputs the PIN number many times.

  When the count value of the counter 309 has not reached the second value (NO in S91), the control unit 306 indicates to the data transmitting / receiving unit 305 that the withdrawal limit is reduced by a predetermined amount. The information is transmitted to the automatic teller machine 200. When the data transmitting / receiving unit 201 of the automatic teller machine 200 receives the information, the control unit 2021 of the automatic teller machine 200 causes the display unit 203 to display a message indicating that the withdrawal limit is reduced (S92). On the other hand, the control unit 306 of the host computer 300 reduces the withdrawal limit by a predetermined amount, and the withdrawal limit for the depositor stored in the customer information storage unit 3081 is reduced. The limit is rewritten (S93). The control unit 306 sets a flag indicating that the withdrawal limit of the depositor has been reduced (flag = 1). Note that if the withdrawal limit is equal to a predetermined reference amount, the control unit 306 sets flag = 0.

  If the authentication unit 307 determines in S88 that the input information is a legitimate password (YES in S88), the control unit 306 determines whether the flag is set ( If the flag is set (“1” in S95), the data transmission / reception unit 305 transmits information indicating the withdrawal limit that has been reduced to the automatic teller machine 200. When the data transmitting / receiving unit 201 of the automatic teller machine 200 receives the information, the control unit 202 determines whether or not to withdraw at the current withdrawal limit (for example, the withdrawal limit is specifically displayed). Is displayed on the display unit 203 (S97). Here, when an instruction to withdraw money is input to the operation unit 206 by the depositor (YES in S98), the control unit 202 uses the operation unit 206 with an amount within the reduced withdrawal limit. Is permitted to accept a withdrawal instruction from the depositor (S99).

  When the flag is not set (“0” in S95), the data transmission / reception unit 305 transmits information indicating the withdrawal limit according to the reference amount that has not been reduced to the automatic teller machine 200. When the data transmission / reception unit 201 of the automatic teller machine 200 receives the information, the control unit 202 sends the withdrawal amount from the depositor to the operation unit 206 within the predetermined withdrawal amount limit. An instruction is accepted (S96). During the withdrawal process by the control unit 2021, security information necessary for the withdrawal process is exchanged with the control unit 306 of the host computer 300.

  In S87, if the authentication unit 307 determines that the withdrawal limit restoration password is valid (YES in S87), the control unit 306 determines the withdrawal amount of the depositor in advance. The withdrawal amount information for the depositor having the ID information stored in the customer information storage unit 3081 is rewritten with the increased withdrawal amount limit (S94). That is, when the processing of S86, S87, S94, S97, and S98 is repeated, the withdrawal limit of the depositor is increased in accordance with the increase in the number of withdrawals for withdrawal withdrawal amount restoration. .

  The withdrawal amount increase amount in S94 is preferably the same amount as the withdrawal limit reduction amount in S93, but may be different amounts. Note that the control unit 306 repeatedly raises the withdrawal limit, and sets the flag to 0 when the withdrawal limit returns to the normal reference amount. Subsequent processing is the same as S95 to S99 described above.

  If no deposit instruction is input to the operation unit 206 by the depositor (NO in S98), the control unit 202 returns the process to S85. That is, the control unit 2021 enables the depositor to input a password or a withdrawal limit restoration password. As a result, the depositor withdraws the money within the current withdrawal limit or inputs the withdrawal limit restoration password again to the operation unit 206 and further raises the withdrawal limit and then withdraws. Can be selected.

  The present invention is not limited to the configuration of the above embodiment, and various modifications can be made. For example, in each of the above embodiments, the control unit 103 of the multifunction device 1 and the control unit 2021 of the automatic teller machine 200 indicate that if an incorrect password or personal identification number is input, the operational performance deteriorates or the withdrawal limit Is displayed on the display unit 473 or 203, but the control unit 103 or 2021 displays a message prompting the user to input ID information, a password, and a personal identification number without displaying them. It may be displayed on the section 473 or 203, or an operation performance degradation process or a withdrawal limit reduction process may be performed.

  In each of the above embodiments, the control unit 103 of the multifunction device 1 and the control unit 2021 of the automatic teller machine 200 must reach the first value even if an incorrect password or password is input. For example, the operation performance lowering process or the withdrawal limit reduction process is not performed, but the control unit 103, 202 or 306 does not perform the operation performance lowering process or the output when an incorrect password or password is input. You may make it perform a gold limit reduction process. In this case, the control unit 103, 202, or 306 does not perform the operation control based on the second value described above.

  In the above embodiment, the electronic device according to the present invention is described as the multi-function device 1 automatic teller machine 200 or the automatic cash deposit system 500, but the electronic device according to the present invention is the multi-function device 1, cash It is not limited to the automatic teller machine 200 or the automatic teller machine 500, and may be another electronic device.
