After that, when the user inputs the two passwords of the old and new into the numeric keypad, a password change message in a certain format is created and transmitted to the entry / exit management device 25, and the reception from the entry / exit management device 25 is received. wait.

When the processing section 27 of the entry / exit management device 25 receives the above message from the gate device 20, it searches the registration table 26 for the identification name of the ID card in the message. If this identification name is registered in the registration table 26, it is checked whether the password registered in the item of the corresponding identification name read from the table matches the old password in the message. If it is determined that they match, a record is added to the change history table 28 as a history, for example, the identification name of the personal identification number change target and the date of the day. next,
The personal identification number of the corresponding item registered in the registration table 26 is replaced with the new personal identification number in the message, a response indicating that the personal identification number has been updated is returned to the requesting gate device 20, and the process is terminated.

When the gate device 20 receives the response from the entry / exit management device 25, the gate device 20 determines whether or not the content of the change has been completed or cannot be changed (for example, when the check between the identification name and the old password has failed). After indicating whether the display lamp on the operation surface is lit or blinking for a certain period of time, the storage of the change request is deleted, and the process is terminated.

[0009]

The user inputs the password using the numeric keys of the numeric keypad 12, cancels the password input immediately before using the cancel button 13 as necessary, and inputs the password again.

A card reading section 14 is provided as an interface for the card identification means 3. When an ID card is inserted into the card insertion slot 15 of the card reading section 14, card information recorded on the card is read.
The card reading unit 14 may read information recorded on a card when inserted into the insertion slot 15, or may read information in a non-contact manner by approaching the card reading unit 14. That is, as an ID card, a non-contact card can be used in addition to an IC card and a magnetic stripe card. Further, a fingerprint reading unit 16 is provided as an interface of the fingerprint matching unit 5, and when a fingerprint of, for example, an index finger is applied to the fingerprint reading unit 16, fingerprint information is read.

Next, the first embodiment configured as described above
The operation of the entry / exit management system will be described with reference to the flowchart of FIG. In FIG. 3, a password and an ID are used.
An entry / exit management system that performs qualification determination using both cards will be described. First, a user inserts an ID card into the insertion slot of the card reading unit 14 on the operation panel 11 provided at an entrance to a building or a site, and inputs a password from the ten key unit 12 (step S101). The entry / exit control unit 7 of the gate device 2 transmits the information of the inserted card ID and the input personal identification number to the entry / exit management device 1 as a gate control request (step S102).

Upon receiving the gate control request (step S103), the qualification discriminating unit 8 of the entry / exit management device 1 is permitted to pass through the building or the premises according to the card identification name and the entered password. A qualification determination as to whether or not the person is a qualified person is performed (step S104). First, a card identifier registered in the qualification information registration unit 9 is searched (step S105), and it is determined whether or not the inserted card identifier corresponds to one of the registered identifiers (step S105). Step S106).

If the inserted card identifier corresponds to the registered identifier (YES in step S106), a predetermined password is registered in the qualification information registration unit 9 corresponding to the identifier. Parameter conversion using parameters is performed (step S107). Then, it is checked whether or not the password converted after the parameter conversion matches the input password (step S108). If they match (YES in step S108), the qualification determination unit 8 sends a gate opening request to the entry / exit control unit 7 of the gate device 2 and responds to the entry / exit control unit 7 of the gate device 2 that the process is successful (step S108). S109). Then, the entry / exit control unit 7 opens the gate, and the user can enter the building or the site.

When the inserted card identifier does not correspond to the identifier registered in the qualification information registration unit 9 (step S1).
06 (NO) or when the password after parameter conversion does not match the input password (step S10).
(NO in 8), the qualification discriminating unit 8 responds to the entry / exit control unit 7 of the gate device 2 that the processing is unsuccessful (step S110), and ends the processing.

Next, the parameter conversion shown in step S107 of FIG. 3 will be described with reference to FIG. here,
FIG. 4 is a diagram showing an example of converting a registered password registered in the qualification information registration unit 9 into parameters. The registered password of the table shown in FIG. 4 is stored in the qualification information registration unit 9, and the day of the week parameter is stored in the parameter unit 10. Then, the qualification determination unit 8 converts the password stored in the qualification information registration unit 9 based on the day of the week parameter stored in the parameter unit 10. Here, the day of the week parameters stored in the qualification information registration unit 9 are “1” for the day of the week parameter on Monday, “2” for the day of the week parameter on Tuesday, “3” for the day of the week parameter on Wednesday,
The day parameter of Thursday is “4”, the day parameter of Friday is “5”, the day parameter of Saturday is “6”, and the day parameter of Sunday is “7”. When the password stored in the qualification information registration unit 9 is “123”, the qualification determination unit 8 performs a parameter conversion by multiplying the registration password by the day-of-week parameter.

More specifically, if the day on which the personal identification number is to be input is Monday, the user inputs (registered personal identification number “123” × day of the week parameter “1”) = “123”. Also,
In the case of Tuesday, (registered personal identification number “123”) × day of the week parameter “2”) = “246” is input. As a result, the password after the parameter conversion matches the input password, and the gate is opened.

With the above-described configuration, since the personal identification number is automatically changed depending on the day of the week, the trouble of the user or the system administrator to change the personal identification number becomes unnecessary, and security management can be simplified. In addition, even if a malicious user who knows the password tries to intrude illegally, he / she cannot enter without knowing the existence of the parameter. Can be improved. Furthermore, by using the day of the week as a parameter for changing the security code, compared to a case where the security code is frequently changed to prevent the security code from being leaked, a qualified person (user) who is permitted to pass through can forget the security code. As a result, it is possible to prevent entry into the room as much as possible.

The parameters may be changed according to date, time, illuminance, month and the like in addition to the day of the week. Further, the parameter conversion is not limited to the method of multiplying the registered password, but may be a method of adding the parameter value to the registered password, as long as the parameter can be easily calculated by the user.

Embodiment 2 FIG. Another embodiment of the entry / exit management system according to the present invention will be described with reference to FIG. FIG. 5 is a diagram showing the number of times of reading of the magnetic card at each time stored in the parameter section of FIG. The registered magnetic numbers in the table shown in FIG. 5 are stored in the qualification information registration unit 9,
The number of times the magnetic card is read as a parameter is stored in the parameter section 10. In FIG. 5, at time 0:00
The card reader 14 reads the identifier A of the magnetic card once from 6:00 to 6:00, and reads the identifier A of the magnetic card twice from 6:00 to 12:00 at 12:00.
The gate is set to be read three times between 18:00 and 18:00, and to be read four times between 18:00 and 24:00. .

Note that the basic configuration of the entry / exit management system is the same as that of the first embodiment, and a description thereof will be omitted. Also,
The same or corresponding portions as in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

Next, the operation of the entry / exit management system according to the second embodiment will be described with reference to the flow chart of FIG.
FIG. 6 illustrates an entry / exit management system that performs qualification determination using a magnetic card. First, the user operates the operation panel 11 provided at the entrance to the building or site, and
Then, the magnetic card is inserted a predetermined number of times corresponding to the time, and the card identification means 3 reads the inserted identification name (step S).
201). The entry / exit control unit 7 of the gate device 2 transmits the card identification name and the information on the number of times of reading the identification name to the entry / exit management device 1 as a gate control request (Step S20).
2). The operations from S203 to S205 are the same operations as S103 to S105 in the first embodiment, and the description is omitted.

When the card identifier of the inserted magnetic card corresponds to the registered identifier (Y in step S206)
ES), a parameter which is the number of times of reading the magnetic card corresponding to the current time is calculated (step S207).
Then, it is checked whether or not the calculated number of times of reading, which is a parameter, matches the number of times the magnetic card has been actually read (step S208). If they match (YES in step S208), the gate device 2 is checked. A gate opening request is transmitted to the entry / exit control unit 7 so as to perform control to open the gate of the gate device 2, and the entry / exit control unit 7
Is returned to the server (step S209). If the number of times of reading, which is a parameter, does not match the number of times the magnetic card has been actually inserted (NO in step S208), a failure in processing is returned to the entry / exit control unit 7 of the gate device 2 (step S210), and the processing ends. .

With the above configuration, the number of times of reading (inserting) the card is automatically changed depending on the time.
It is not necessary for the user or the system administrator to change the identification method, and security management can be simplified. In addition, even if a malicious user who has obtained the magnetic card attempts to intrude illegally, he or she cannot intrude without knowing the existence of a parameter that the number of readings changes according to the time, and a double check is performed.

The parameters may be changed depending on the date, the day of the week, the illuminance, the month, and the like in addition to the time.

Embodiment 3 In the present embodiment, a combination of input methods of qualification information will be described below. Specifically, there is a method in which a method for inputting card identification, inputting a personal identification number, and inputting qualification information for fingerprint collation is changed by a predetermined parameter. As an example of the change, for example, when the predetermined parameter is set to daytime or nighttime, qualification can be determined by card identification and password input during daytime and card identification and fingerprint verification at nighttime. The distinction between daytime and nighttime is from 6:00 to 18:00 in the daytime and from 18:00 to 18:00.
Even if it is classified according to the time zone in which night until 6:00, the illuminometer may be used to determine 50 lux or more as daytime and 50 lux or less as nighttime.

With such a configuration, the input method of the qualification information is automatically changed between daytime and nighttime, so that there is no need for the user or the system administrator to change the input method.
Security management can be simplified. Also,
Even if a malicious user attempts to intrude illegally, it is impossible to intrude without knowing the existence of the parameter that the input method of the credential is changed, and the security of the entry / exit management system can be improved. .
