Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal identification device using a personal identification number applied to an access control system and the like.
In particular, the present invention relates to a personal identification device that requests an operator to change a password every predetermined period.

[0002]

2. Description of the Related Art Conventionally, personal identification devices have been used to manage the entry and exit of passers-by to and from important areas. As the personal identification device, for example, a card (magnetic card, IC,
Cards, non-contact cards, etc.), numeric keys, fingerprints, voice prints, palm shapes, irises, holograms, face images, and the like.
Among them, in particular, a card or a numeric keypad is often used in terms of convenience and economy. In some cases, these are used in combination to enhance security.

[0003] When a card is used as a personal identification device, there is no problem that the card information can be stolen at the time of operation, but if the card is lost, anyone who has picked up the card can enter and leave. There is a problem.
In particular, when a magnetic card is used, there is also a problem in security because the card can be easily copied.

[0004] Further, when a numeric keypad is used for the personal identification device, there is an advantage that a passerby only needs to store the password for inputting the numeric keypad and does not need to possess anything. There is a problem that, if a third party is known, anyone who knows the password can enter and leave. Also, in consideration of security, the security code used for the numeric keypad is changed periodically, but the changed security code must be passed on to all passers-by, which makes the procedure very complicated. There are also problems. Therefore, it is conceivable to assign a different personal identification number to each person and manage the personal identification number for each individual. However, in this case, as the number of passers-by increases, the number of personal identification numbers also increases accordingly, so that there is a problem that the probability of collation even if random input is increased increases.

Therefore, there is a method of enhancing security by combining a numeric keypad and a card in a personal identification device.
This makes it possible to further reduce the probability that a third party illegally enters and exits compared to the case where the numeric keypad and the card are used alone. In addition, since the individual can be identified by the card, it is possible to assign a password of a numeric keypad to each individual. However, when managing entry and exit to an important area, it is desirable to periodically change the password used for the numeric keypad in consideration of security.

[0006]

However, since the change of the personal identification number is generally left to the intention of an operator who is a passerby, there are many operators who do not change the personal identification number for a long period of time and lack security. There was a problem.

There is also a method of identifying an individual by combining a ten-key and biometric information such as a fingerprint, a voiceprint, a palm shape, an iris, and a face image. Biometrics is personally unique information and does not have the problem of duplication or theft, and high security can be ensured using only that information. However, since personal identification using biometric information requires extremely complicated processing, there is a problem that it is costly to increase recognition accuracy and speed. Therefore, instead of reducing the accuracy and speed to some extent to reduce the cost, there is an attempt to increase the security while securing the economy by combining with a numeric keypad. Also in this case, it is desirable that the password of the numeric keypad be changed periodically as in the combination of the card and the numeric keypad described above.

A similar problem also occurs when the above-described personal identification device is used for switching security states.

The present invention has been made in view of the above problems, and has as its object to provide a personal identification device capable of requesting an operator to change a personal identification number at regular intervals.

Storage unit 109 and the fifth storage unit 110.

The operating means 101 includes a card (magnetic card,
An IC card, a contactless card, etc.), a fingerprint, a voiceprint, a palm shape, an iris, a hologram, a face image, and the like are identified to identify an operator. In the present embodiment, a card reader is used for the operation means 101. Will be described. Operation means 10
When the operator inputs a card to the card reader as 1, the card reader reads the card information of the input card and outputs the read card information to the control unit 108.

Numeric keypad 102 as password input means
Is a means for inputting a personal identification number (number). When the operator inputs his / her personal identification number using the numeric keypad 102, the input personal identification number is output to the control unit 108.
Note that the numeric keypad 102 may use a push button type or a liquid crystal touch panel.

The first storage section 103 is a storage section for storing information corresponding to card information read by a card reader as the operation means 101, and stores card information of a card owned by a valid operator in advance. It is remembered.

In the second storage unit 104, a password of a valid operator is stored in advance.

The third storage unit 105 is a storage unit for storing the validity period of the personal identification number stored in the second storage unit, and stores the validity period in which the personal identification number can be used for each operator. are doing. The validity period is a period that can be arbitrarily determined by the administrator of the personal identification device 10, and can be determined in consideration of security, such as January, February, or six months from the date of issuing the personal identification number. .

The notifying unit 106 includes a light emitting unit such as an LED, a sounding unit such as a speaker, a visual unit such as a display, and outputs a message to the operator when an activation signal is input from the control unit 108. I do.

The mode setting means 107 is a means for switching the control unit 108 to the password change mode. When the operator operates the mode setting means 107, the mode setting means 107 sends a selection signal to the control unit 108. Is output, and the control unit 108 receiving the selection signal switches to the password change mode. Further, the mode setting means 107
If the control unit 108 determines that the operator's password is not within the valid period, the selection signal may be automatically output.

The mode setting means 107 may use a push button type or a liquid crystal touch panel. In the present embodiment, the information is displayed on a display (not shown).

The fourth storage unit 109 is a storage unit for storing that the warning unit 106 has output the warning message to the operator.

The fifth storage unit 110 is a storage unit for storing a period during which the operator desires to change the personal identification number.

As shown in FIG. 2, the control unit 108 includes an operation unit 101, a numeric keypad 102, a first storage unit 103,
Storage unit 104, third storage unit 105, notification unit 106,
The control unit is connected to the mode setting unit 107, the fourth storage unit 109, and the fifth storage unit 110, and controls them.

Next, an outline of a process for determining a valid operator based on card information and a password will be described. When receiving the operator's card information from the card reader as the operation means 101, the control unit 108 calls the card information corresponding to the received card information from the first storage unit 103, and determines whether the operator's card is valid. Or collation. As a result, when both match, it is determined that the operator's card is valid, and the input of the operator's password is accepted from the ten keys 102. When the operator inputs a password using the numeric keypad 102, the numeric keypad 102 outputs the input password to the control unit 108. Control unit 10
8 specifies the owner from the card information, calls the corresponding password from the second storage unit 104, and determines whether the password received from the numeric keypad 102 matches the password called from the second storage unit. Perform collation. As a result, if they match, it is determined that the password of the operator is valid.

The control unit 108 determines the operator by determining the validity of the card information and the password, but may determine the operator by determining only the validity of the card information. .

Next, an outline of a process for determining whether or not the operator's password is within the valid period will be described. The control unit 108 calls the validity period of the personal identification number corresponding to the valid operator's personal identification number from the third storage unit 105 and checks whether the operator's personal identification number is within the validity period. . As a result, if the control unit 108 determines that the password of the operator has passed the validity period, the notification unit 106
And a notifying unit 106 outputs a password change message to the operator.

Next, a description will be given of an outline of processing when it is determined that the password of the operator is within the period in which the change of the password is desired.

Here, the period during which the change of the personal identification number is desired refers to a period that can be arbitrarily set by the administrator. If the administrator sets the password change desired period to two weeks, if the personal identification device 10 is operated by the operator after two weeks before the end of the validity period of the password, the control unit It is determined by 108 that the operation is within the desired password change period, and the notification unit 106 can notify the operator as a warning message that the validity period of the password will soon expire. If the personal identification device 10 is operated by the operator on a day earlier than two weeks before the personal identification number is counted from the last day of the validity period, the control unit 108 determines that the operation is outside the personal identification number change desired period. You.

The password change desired period is stored in the fifth storage unit 110.

When the control unit 108 determines that the password of the operator is within the password change desired period, the control unit 108 specifies the operator who has output the warning message and stores the fourth message in the fourth storage. The warning content is output to the unit 109, and the fourth storage unit 109 stores the received warning content.

In this case, the stored contents may include only the presence / absence of a warning, the warning date, the number of warnings, and the like. By storing the number of warnings and the like, it is possible to separately alert a passerby who has received the warning message many times.

Next, an outline of the processing when it is determined that the validity period of the operator's password has passed and a warning message has been output to the operator before has been described. The control unit 108 determines whether or not the operator has previously received the display of the warning message on the assumption that the password is not within the validity period. Requests output of warning contents.

The fourth storage unit 109 outputs a warning content to the control unit 108 if the password of the corresponding operator is set in response to an output request from the control unit 108. On the other hand, if the password of the corresponding operator has not been set, it outputs that no warning has been set.

Upon receiving the output from the fourth storage unit 109, the control unit 108 determines whether the operator has previously received a warning message. As a result, the control unit 108
If the operator has determined that a warning message has been received before, the notification unit 106 outputs an error message.

Next, an outline of a case where the operator changes the personal identification number will be described. The control unit 108 specifies the owner from the card information and stores the corresponding personal identification number in the second storage unit 104.
And checks whether the password received from the numeric keypad 102 matches the password called from the second storage unit.

As a result, if the control unit 108 determines that both match, it accepts the input of a new password.
Then, the operator uses the numeric keypad 102 to input a new password, and the numeric keypad 102 outputs the input new password to the control unit 108. When receiving the new password, the control unit 108 rewrites the password set in the second storage unit 104 with the new password.

The new password may be input twice for confirmation. Further, if the control unit 108 determines that the new password input by the operator is the same as the password set in the second storage unit 104, the control unit 108 may not accept the input password. Good.

Next, the operation of the control unit 108 of the access control system using the personal identification device of the present invention will be described with reference to FIGS.

FIG. 3 is a flowchart showing the operation of the first embodiment in which a message is output from the notification unit when the control unit determines that the validity period of the personal identification number has expired. FIGS. FIG. 9 is a flowchart illustrating an operation of a second embodiment of automatically switching to a password change mode when the unit determines that the validity period of the password has expired;
FIG. 6 shows a case where the control unit determines that the validity period of the personal identification number has passed, and determines that the warning message has been output to the operator before, and the operator sets the mode setting means. 13 is a flowchart illustrating an operation of a third embodiment for invalidating an operation. [Embodiment 1] In FIG. 3, the operator inserts his / her own card into a card reader which is operation means 101,
The card reader reads the card information from the card of the operator and outputs the card information of the operator to the control unit 108.

In step 1, the control unit 108 receives the card information of the operator from the card reader as the operation means 101, and proceeds to step 2. In step 2, the control unit 108 retrieves card information corresponding to the received card information from the first storage unit 103, and checks whether or not the two match. As a result, if they do not match, it is determined that the operator's card is not valid, and an error message is output from the notification unit 106 in step 7. On the other hand, if both match, it is determined that the operator's card is valid and the ten key 1
02 accepts the input of the operator's password. The operator inputs a password using the numeric keypad 102, and the numeric keypad 102 outputs the input password to the control unit 108.

In step 3, the control unit 108 specifies the operator from the card information and enters the corresponding password into the second password.
Is checked from the storage unit 104, and whether the password received from the numeric keypad 102 matches the password called from the second storage unit 104 is checked. As a result, the control unit 10
8 determines that the password of the operator is not valid when the two do not match, and outputs an error message from the notification unit 106 in step 7. It is determined that the personal identification number is valid, and in step 4, the validity period of the personal identification number corresponding to the valid operator's personal identification number is called from the third storage unit 105, and the personal identification number is within the validity period. Check if it is.

As a result, if the control unit 108 determines that the valid period of the personal identification number has passed, in step 5, the control unit 108 outputs a start signal to the notifying unit 106 and receives the start signal. The notification unit 106 outputs a password change message to the operator. For example, a message such as "Please change your password" is output.

Here, when the operator desires to change the password, the password can be changed by performing a predetermined operation.

If it is determined in step 4 that the operator's password is within the valid period, or if a message is output in step 5, the unlock signal S is output in step 6. Is output (see FIG. 2), the electronic lock 20 is unlocked, and entry and exit of the operator are permitted. In this case, even if the operator does not change the password, in step 6, the unlock signal S is output, and the entry and exit of the operator are permitted.

In this embodiment, the operator is specified by the password using the numeric keypad and the validity period of the password is determined. However, the validity period of the password of the operator may be determined by the card information.

In this embodiment, the operator is specified by inputting the personal identification number after operating the card. However, the operator may be specified in the reverse operation procedure. [Second Embodiment] (Operation Example 1) Next, when the control unit 108 determines that the validity period of the personal identification number has passed, the operation 1 for automatically switching to the personal identification number change mode will be described with reference to the flowchart of FIG. Will be explained.

When the operator inserts his / her own card into the card reader which is the operation means 101, the card reader reads the card information from the operator's card, and
8 outputs the card information of the operator. In step 11, the control unit 108 receives the card information of the operator from the operation unit 101, and proceeds to step 12.

In step 12, the control unit 108
The card information corresponding to the received card information is called out from the first storage unit 103, and whether or not the operator's card is valid is checked. As a result, if they do not match, it is determined that the card is not valid, and step 21
, An error message is output from the notification unit 106. On the other hand, when the two match, the control unit 108
It is determined that the card is valid, and in step 13, the card owner is specified from the card information, the validity period of the personal identification number is called from the third storage unit, and the personal identification number of the operator is within the validity period. Check if it is. As a result, if the control unit 108 determines that the password of the operator is within the validity period, the control unit 108 receives an input of the password of the operator using the ten keys 102.

The operator inputs his / her personal identification number using the numeric keypad 102, and the numeric keypad 102 outputs the input personal identification number to the control unit 108. In step 14, the control unit 108 identifies the owner from the card information, calls the corresponding personal identification number from the second storage unit 104, and the personal identification number received from the numeric keypad 102 and the personal identification number called from the second storage unit. Is checked to see if they match.

As a result, if they match, it is determined that the input personal identification number is valid, and in step 15, an unlocking signal S is output to the electronic lock 20 to permit entry and exit. . On the other hand, if they do not match, it is determined that the input password is not valid, and an error message is output from the notification unit 106 in step 21.

Next, at step 13, the control unit 10
The operation performed when the validity period of the personal identification number of the card owned by the operator has expired will be described.

If it is determined in step 13 that the password is not within the validity period, the mode setting means 17
Outputs a selection signal to the control unit 108. Step 16
When the control unit 108 receives the selection signal from the mode setting unit 17, the control unit 108 shifts to the password change mode.
When the mode shifts to the password change mode, the display on the display (not shown) is switched to a password change screen. That is, in step 13, when the control unit 108 determines that the password of the operator is not within the validity period, the operator automatically changes the password without performing any operation of the mode setting unit. Switch to mode.

For this reason, the password can be forcibly changed by the operator.

Next, the operation for changing the personal identification number will be described.

The control unit 108 requests the operator to input a password. The operator uses the numeric keypad 102 to enter the current personal identification number currently used. Numeric keypad 102
Receives the input of the current personal identification number, and outputs the inputted current personal identification number to the control unit 108.

In step 17, the control unit 108
The owner is specified from the card information and the corresponding personal identification number is called from the second storage unit 104, and it is checked whether the current personal identification number received from the numeric keypad 102 matches the personal identification number called from the second storage unit. Do. As a result, if they do not match, it is determined that the password input by the operator is not valid, and at step 21, the notification unit 1
From 09, an error message is output. On the other hand, if they match, it is determined that the current password input by the operator is valid, and the input of the new password by the operator is accepted.

When the operator uses the numeric keypad 102 to input a new password, the numeric keypad 102 outputs the input password to the control unit 108. When the control unit 108 receives the new password at step 18, the control unit 108 rewrites the current password set in the second storage unit 104 with the new password at step 19.

Further, in step 20, the validity period of the personal identification number set in the third storage unit 105 is updated. Then, in step 15, an unlocking signal S is output to the electronic lock 20, and entry and exit are permitted. (Operation Example 2) Next, an operation 2 of automatically switching to the password change mode when the control unit 108 determines that the validity period of the password has expired will be described with reference to the flowchart of FIG.

When the operator inserts his / her own card into the card reader, which is the operating means 101, the card reader reads card information from the operator's card, and
8 outputs the card information of the operator. In step 101, the control unit 108 receives the card information of the operator from the operation unit 101, and proceeds to step 102.

In step 102, the control unit 108
Sends the card information corresponding to the received card information to the first
And checks whether the operator's card is valid or not. As a result, if they do not match, it is determined that the card is not valid, and step 2
At 01, an error message is output from the notification unit 106. On the other hand, if the two match, the control unit 108 determines that the card is valid, and
2 accepts the input of the password of the operator. The operator inputs a password using the numeric keypad 102, and the numeric keypad 102 outputs the input password to the control unit 108.

In step 103, the control unit 108
Specifies the operator based on the card information, calls the corresponding password from the second storage unit 104, and determines whether the password received from the numeric keypad 102 matches the password called from the second storage unit 104. Perform collation. As a result, when the two do not match, the control unit 108 determines that the password of the operator is not valid, and when the two match, the password of the operator is valid. In step 104, the validity period of the password corresponding to the valid operator's password is called from the third storage unit 105, and it is confirmed whether the operator's password is within the validity period. .

As a result, when it is determined that the validity period of the personal identification number has passed, the mode setting means 107 outputs a selection signal to the control unit 108. In step 106, upon receiving the selection signal from the mode setting means 107, the control unit 108 shifts to the password change mode. When the mode shifts to the password change mode, the display on the display (not shown) is switched to a password change screen. That is,
In step 104, when the control unit 108 determines that the password of the operator is not within the validity period,
The operator automatically switches to the password change mode without performing any operation on the mode setting means.

Therefore, the password can be forcibly changed by the operator.

Next, the operation for changing the personal identification number will be described.

The control unit 108 requests the operator to input a new password. When the operator uses the numeric keypad 102 to input a new password, the numeric keypad 102 outputs the input password to the control unit 108. In step 107, when receiving the new password, the control unit 108 rewrites the current password set in the second storage unit 104 with the new password in step 108.

Further, in step 109, the validity period of the personal identification number set in the third storage unit 105 is updated. Then, in step 105, the electronic lock 20
And an unlocking signal S is output, and entry and exit are permitted.

Note that both the operations 1 and 2 of the present embodiment
Although an operator is specified by inputting a personal identification number after operating a card, the operator may be specified by a reverse operation procedure. [Embodiment 3] Next, if the control unit determines that the validity period of the password has expired and determines that a warning message has been output to the operator, the mode by the operator is set. The operation of invalidating the operation of the setting means will be described with reference to the flowchart of FIG.

When the operator inserts his / her own card into the card reader which is the operation means 101, the card reader reads the card information from the card of the operator and outputs the card information of the operator to the control unit 108. . Step 21
In, the control unit receives the card information from the card reader, and proceeds to step S22.

In step 22, the control unit 108
The card information corresponding to the received card information is called out from the first storage unit 103, and whether or not the operator's card is valid is checked. As a result, if they do not match, it is determined that the operator's card is not valid, and an error message is output from the notification unit 106 in step 36. On the other hand, if the two match, it is determined that the operator's card is valid, and in step 23, the control unit 108 specifies the card owner based on the operator's card information, and performs the third storage. Section calls the validity period of the password, and confirms whether the operator's password is within the validity period.

As a result, if it is determined that the password of the operator is within the valid period, the process proceeds to the next step 24, where the password of the operator is within the desired period for changing the password. Is determined. As a result of the determination, the control unit 108
If it is determined that the password of the operator is within the password change desired period, the warning unit 106 outputs a warning message to the operator in step 25.

Next, in step 26, if the operator who has received the warning message desires to change the password, the mode setting means 10 displayed on the display is displayed.
When the user operates 7 to select the change to the password change mode, the mode setting means 107 outputs a selection signal to the control unit 108 and shifts to the password change mode. Step 2
In step 6, if the mode setting means 107 is not operated by the operator, the process proceeds to step 27.

At step 27, the control unit 108
The operator is specified, the warning content is output to the fourth storage unit 109, and the fourth storage unit 109 stores the warning content received from the control unit 108.

If it is determined in step 24 that the password is outside the password change desired period, or if the warning content is stored in the fourth storage unit in step 27, the password by the operator is changed. Accept the number input. When the operator inputs a password using the numeric keypad 102, the numeric keypad 102 outputs the input password to the control unit 108.

At step 28, the control unit 108
The owner is specified from the card information, the corresponding password is called from the second storage unit 104, and whether or not the password received from the numeric keypad 102 matches the password called from the second storage unit is checked. . As a result, if they match, it is determined that the password of the operator is valid, and in step 29, an unlocking signal S is output to the electronic lock 20, and entry and exit of the operator are permitted. . On the other hand, if it is determined that they do not match, it is determined that the password of the operator is not valid, and at step 36, the notification unit 1
From 06, an error message is output.

Next, the operation in the case where the validity period of the operator's password has passed in step 23 will be described. In step 23, if the control unit 108 determines that the password is not within the validity period, the control unit 108 determines whether the operator has previously received the display of the warning message. At 109, a request for output of warning contents is made. The fourth storage unit 109 outputs a warning content to the control unit 108 if the password of the corresponding operator is set in response to the output request of the control unit 108. On the other hand, when the password of the corresponding operator is not set, the control unit 10
8 that no warning content is set.

At step 30, the control unit 108
Upon receiving the output from the fourth storage unit 109, it is determined whether or not the operator has previously received a warning message. As a result, when it is determined that the operator has previously received the warning message, the control unit 108 outputs an error message from the notification unit 106 in step 36.
For this reason, the operator who received the warning message before cannot enter the important area because he did not change his password within the desired password change period and could not perform the operation to change the password. You can't do that.

If it is determined in step 30 that the operator has not received the warning before and the user desires to change the password, or if in step 26 the user desires to change the password, the operator Operates the mode setting means 107 displayed on the display and selects the change to the password change mode. When the operator selects the change to the password change mode, the mode setting means 107 outputs a selection signal to the control unit 108. In step 31, the control unit 108 receives the selection signal and enters the password change mode. Transition.

The operation of changing the personal identification number in steps 32 to 35 is the same as that in steps 17 to 20 in FIG.

In the present embodiment, the operator is specified by inputting the personal identification number after operating the card. However, the operator may be specified in the reverse operation procedure.

Although the preferred embodiments of the present invention have been described above in detail, the present invention is not limited to the specific embodiments, and within the scope of the present invention described in the claims, Various modifications and changes are possible.
For example, the personal identification device of the present invention can be used for security state switching.
