Description

  The present invention relates to an entrance / exit management system and an entrance / exit management method for managing a user's entrance / exit from a recording medium such as an IC card possessed by the user or biological information such as a user's fingerprint in a research facility.

  Conventionally, in research facilities, etc., security of entrance / exit control has been made highly reliable, and anti-passback control has been implemented to prevent entry / exit due to other people's card operations and other unauthorized operations. (For example, refer to Patent Document 1). Anti-passback control is to check the entrance by card operation at the time of entering the room, and check the exit by card operation at the time of leaving the room. This prevents the room from entering continuously, and prevents other rooms from being entered without leaving the room. With this anti-passback control, it is possible to manage the entrance and exit (traffic line) of a person and to check the status of the room.

JP 2004-84278 A

  In an entrance / exit management system that employs anti-passback control, if an error (passback violation) occurs for some reason, a remedy is required. The reason is that if the person who tries to enter or leave the room is not passed in some way, the person cannot go out and is confined. In other words, such an entry / exit management system cannot be operated so that it cannot be passed when an error occurs due to its nature. For this reason, it is necessary to take a remedy such as making it possible to enter / exit by contacting the monitoring room, or enabling entry / exit by the card operation again.

  However, providing such a remedy means that even if a passback violation occurs, it is possible to enter and leave the room as a result, and by using this remedy, it is possible to enter and exit without keeping the operation. There was a problem. Such a problem also occurs in an entrance / exit management system using biometric information such as a user's fingerprint.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide an entrance / exit management system and an entrance / exit management method capable of thoroughly managing entrance / exit.

In the entrance / exit management system for managing the user's entrance / exit based on the recording medium possessed by the user or the user's biometric information, the present invention is arranged at various locations in the management target facility and reads the identification information from the approaching recording medium, Alternatively, the reading means for reading the biological information from the approaching user, the position of the user specified based on the identification information or the biological information, and the user's traffic history are collated, and the result of the collation is set for each user. Based on the entry / exit permission information, there is an anti-passback violation in which the collating means for determining whether or not the specified user is allowed to pass and the specified user position and the traffic history are not consistent and the traffic is not allowed. Counting means for counting the number of anti-passback violations for each user when it occurs, and a user who satisfies the predetermined condition for the number of anti-passback violations A judging means regarded as addict anti passback violation, by changing and out permission information of the user is regarded as the addict, in which and a limiting treatment means to restrict the passage of the user.
Further, in one configuration example of the entrance / exit management system of the present invention, the determination means regards a user whose anti-passback violation exceeds a predetermined threshold as an anti-passback violation addict. Is.
Further, in one configuration example of the entrance / exit management system of the present invention, the determination means has a ratio of the number of violations of the anti-passback to the number of normal passes permitted by the verification means exceeds a predetermined threshold value. The user is regarded as an addict of anti-passback violations.

Further, the present invention relates to a recording medium possessed by a user or an entrance / exit management method for managing a user's entrance / exit based on the user's biometric information, from a recording medium approached by reading means arranged at various locations in the managed facility. A reading procedure for reading the identification information or reading the biological information from the approaching user, the position of the user specified based on the identification information or the biological information, and the user's traffic history are collated, and the result of the collation Based on the access permission information set for each user, a collation procedure for determining whether the identified user can pass,
The counting procedure for counting the number of anti-passback violations for each user when the identified user position and the traffic history do not match and an anti-passback violation that does not permit traffic occurs, and the anti-pass Change the decision procedure to consider users who satisfy the prescribed number of back violations as anti-passback addicts, and change the access permission information of the users considered as addicts, and limit this user's traffic A restriction procedure.

  According to the present invention, by counting the number of anti-passback violations for each user, the system administrator can identify the violators who enter and leave the room without regularly observing the operation. In the present invention, a user who satisfies the predetermined number of anti-passback violations is regarded as an anti-passback violation addict, dynamically changes the access permission information of the user, and restricts the user. By imposing, it is possible to prevent the violator from entering or leaving the room without observing the operation, and as a result, thorough entry / exit management can be performed. In addition, by setting a condition as to whether or not to be regarded as an addict when changing the access permission information, an anti-passback violation can be allowed for a non-malicious user and only the addict can be controlled.

  In addition, by comparing the ratio of the number of anti-passback violations to the number of normal passes with a threshold value, it is possible to grasp the tendency for each user regardless of the number of traffic, and the occurrence of anti-passback violations. It is possible to discriminate whether it is a non-malicious user or an addict.

The current partitions in the current location management information DB21, DB22, and DB23 are all set to “−” in the initial state before starting operation.

  Hereinafter, the operation of the present embodiment will be described by taking as an example the case where the user M holding the IC card 4 enters the room along the route P shown in FIG. FIG. 8 is a flowchart showing the operation of the entrance / exit controllers 7-1 to 7-3. It is assumed that “001” is written as the card ID in the IC card 4 held by the user M.

  First, entering the indoor compartment R2 from the indoor compartment R1 will be described. In the indoor compartment R1, when the user M sets the IC card 4 in the reader 1-2, the reader 1-2 reads the card ID “001” written in the IC card 4, and reads the card ID “001” as the reader. The management code number “READ0002” of 1-2 is sent to the entrance / exit controller 7-1.

  The entrance / exit controller 7-1 receives the card ID “001” and the management code number “READ0002” from the reader 1-2 (steps S101 and S102 in FIG. 8) and assigns the card ID “001” from the current position management information DB 21. The corresponding current section “-” is acquired (step S103), and the room section R1 of the entry source corresponding to the management code number “READ0002” is acquired from the installation position management information DB 11 (step S104). By acquiring the room compartment R1 of the entry source corresponding to the management code number “READ0002” of the reader 1-2, the current position of the user corresponding to the card ID “001” can be specified.

  Then, the entrance / exit controller 7-1 collates the current section “−” acquired in Step S103 with the room section R1 of the entrance source acquired in Step S104 (Step S105). In this case, the current section is “−” indicating the initial value and does not match the room section R1 of the entry source, but the entrance / exit controller 7-1 has “−” where the current section indicates the initial value. In this case, it is determined that the current compartment and the room compartment of the entry source coincide with each other regardless of the room compartment of the entry source.

  Therefore, the entrance / exit controller 7-1 determines that the current section “−” and the room section R1 that is the entry source coincide with each other, and sets the collation result in step S105 as OK. When the collation result is OK (YES in step S106), the entrance / exit controller 7-1 acquires the room compartment R2 of the entrance destination corresponding to the management code number “READ0002” from the installation position management information DB 11, and the entrance / exit permission information DB 31. Referring to FIG. 5, it is determined whether or not the user who has the IC card 4 with the card ID “001” is permitted to enter and exit the room compartment R2 of the room entry destination (step S107). The entrance / exit controller 7-1 causes the reader 1-2 to display a warning message indicating that entry is not allowed when entry / exit to the room compartment R2 at the entry destination is not permitted (step S108).

  If the entrance / exit controller 7-1 determines in step S107 that entry / exit to the entry room compartment R2 is permitted, the entry / exit controller 7-1 designates the current compartment corresponding to the card ID “001” in the current location management information DB 21 as “−”. To the room compartment R2 of the room entry destination (step S109).

  Subsequently, the entrance / exit controller 7-1 enters the room ID message indicating the card ID “001”, the management code number “READ0002” received from the reader 1-2, and the room compartment R2 of the room entrance acquired from the installation position management information DB11. Is globally transmitted to the other entrance / exit controllers 7-2, 7-3 and the center device 6 (step S110). Furthermore, the entrance / exit controller 7-1 unlocks the electric lock (not shown) (step S111), and opens the door of the entrance / exit where the reader 1-2 is installed. As a result, the user M who sets the IC card 4 in the reader 1-2 can enter the indoor compartment R2 from the indoor compartment R1.

  Upon receipt of the entry message from the entry / exit controller 7-1, the entry / exit controller 7-2 extracts the card ID “001”, the management code number “READ0002”, and the room compartment R2 of the entry destination from this entry message. The current section corresponding to the card ID “001” in the position management information DB 22 is rewritten from “−” to the room section R2 of the room entry destination. Similarly, the entrance / exit controller 7-3 rewrites the current section corresponding to the card ID “001” in the current position management information DB 23 from “−” to the room section R2 that is the entry destination, and the center device 6 also manages the current position management. The current section corresponding to the card ID “001” of the information MB2 is rewritten from “−” to the room section R2 of the room entry destination.

  Next, entering the indoor compartment R3 from the indoor compartment R2 will be described. In the indoor compartment R2, when the user M sets the IC card 4 in the reader 1-7, the reader 1-7 reads the card ID “001” written in the IC card 4, and the card ID “001” and the reader The management code number “READ0004” of 1-7 is sent to the entrance / exit controller 7-2.

  The entrance / exit controller 7-2 receives the card ID “001” and the management code number “READ0004” from the reader 1-7 (steps S101 and S102), and the current corresponding to the card ID “001” from the current location management information DB22. A section is acquired (step S103). At this time, the current section corresponding to the card ID “001” is rewritten to the room section R2 by the entry message from the previous entry / exit controller 7-1.

  Then, the entrance / exit controller 7-2 acquires the room compartment R2 of the entry source corresponding to the management code number “READ0004” from the installation position management information DB 12 (step S104), and the current compartment obtained in step S103 and the step S104. The acquired room compartment of the entry source is collated (step S105). In this case, the current section acquired in step S103 is R2, and the room section of the entry source acquired in step S104 is also R2, which are the same.

  Therefore, the entrance / exit controller 7-2 sets the collation result in step S105 to OK. When the collation result is OK (YES in step S106), the entrance / exit controller 7-2 acquires the room compartment R3 of the entry destination corresponding to the management code number “READ0004” from the installation position management information DB 12, and the entrance / exit permission information DB 32 Referring to FIG. 4, it is determined whether or not the user who has the IC card 4 with the card ID “001” is permitted to enter and exit the room compartment R3 of the room entry destination (step S107).

  If the entrance / exit controller 7-2 determines in step S107 that entry / exit to the room compartment R3 of the entry destination is permitted, the entrance / exit controller 7-2 enters the current compartment corresponding to the card ID “001” in the current location management information DB 22 from R2. Rewriting to the previous indoor section R3 (step S109).

  Subsequently, the entrance / exit controller 7-2 receives the entry message indicating the card ID “001”, the management code number “READ0004” received from the reader 1-7, and the room compartment R3 of the entry destination acquired from the installation position management information DB 12. Is globally transmitted to the other entrance / exit controllers 7-1 and 7-3 and the center device 6 (step S110). Furthermore, the entrance / exit controller 7-2 unlocks the electric lock (not shown) (step S111), and opens the door of the doorway where the reader 1-7 is installed. Thereby, the user M who sets the IC card 4 to the reader 1-7 can enter the indoor compartment R3 from the indoor compartment R2.

  Upon receipt of the entry message from the entry / exit controller 7-2, the entry / exit controller 7-1 extracts the card ID “001”, the management code number “READ0004”, and the room compartment R3 of the entry destination from this entry message. The current section corresponding to the card ID “001” in the position management information DB 21 is rewritten from R2 to the room section R3 of the room entry destination. Similarly, the entrance / exit controller 7-3 rewrites the current section corresponding to the card ID “001” of the current position management information DB 23 from the R2 to the room section R3 of the entry destination, and the center device 6 also updates the current position management information MB2. The current section corresponding to the card ID “001” is rewritten from R2 to the room section R3 of the room entry destination.

  Next, entering the indoor compartment R4 through the indoor compartment R2 without an exit operation from the indoor compartment R3 will be described. In the example of FIG. 2, the user M opens the door without the reader from the indoor compartment R3, temporarily exits to the indoor compartment R2, and sets the IC card 4 in the reader 1-9. In this case, the reader 1-9 reads the card ID “001” written in the IC card 4, and uses the card ID “001” and the management code number “READ0008” of the reader 1-9 to enter / exit the controller 7-2. Send to.

  The entrance / exit controller 7-2 receives the card ID “001” and the management code number “READ0008” from the reader 1-9 (steps S101 and S102), and corresponds to the card ID “001” from the current location management information DB22. The current partition is acquired (step S103). At this time, the current section corresponding to the card ID “001” is rewritten to the indoor section R3 by the card operation with the previous reader 1-7.

  Then, the entrance / exit controller 7-2 acquires the room compartment R2 of the entry source corresponding to the management code number “READ0008” from the installation position management information DB 12 (step S104), and the current compartment obtained in step S103 and the step S104. The acquired room compartment of the entry source is collated (step S105). In this case, the current section acquired in step S103 is R3, and the room section that has been acquired in step S104 is R2, and the two do not match.

  Therefore, the entrance / exit controller 7-2 determines that the current section in which the IC card 4 is currently located does not match the room section of the entrance source, and sets NG as the result of the collation in step S105. When the collation result is NG (NO in step S106), the entrance / exit controller 7-2 regards the traffic as unauthorized and displays a warning message indicating that entry is not possible on the reader 1-9 (step S112). This prohibits entry from the indoor compartment R2 into the indoor compartment R4.

When the collation result is NG, the entrance / exit controller 7-2 sends the collation result (anti-passback NG) including the card ID “001” and the management code number “READ0008” received from the reader 1-9 to the center device. 6 (step S113).
In the case of an anti-passback violation in which the verification result is NG, there is a remedy that allows entry / exit, for example, by re-operating the card, and this allows the user to enter / exit. . However, this relief measure may be invalidated when the restriction measures described later are implemented.

  Next, the operation of the center device 6 will be described. FIG. 9 is a flowchart showing the operation of the center device 6. When the center device 6 receives the collation result indicating the anti-passback NG from the entrance / exit controllers 7-1 to 7-3 (YES in step S201 in FIG. 9A), the center device 6 displays an alarm message based on the collation result on the screen. While displaying (step S202), the card ID “001” is acquired from the received collation result, and the anti-passback violation count corresponding to the card ID “001” of the user information MB4 is incremented by 1 (step S203).

  Further, the center device 6 checks the user information MB4 at regular intervals (for example, once a day) to determine whether or not the number of anti-passback violations of each IC card exceeds a predetermined threshold (FIG. Step S204 of 9 (b). When there is an anti-passback violation count for each card that exceeds a threshold, the center device 6 sanctions the user information MB4 for an IC card for which the anti-passback violation count exceeds the threshold. The flag is set to 1 and the number of anti-passback violations is reset to 0 (step S205). For example, in the example of FIG. 3C, the threshold value is 10 times, and the anti-passback violation number of the IC card with the card ID “003” has reached 11 times. Set to 1. In the example of FIG. 9B, the anti-passback violation count is reset when the sanction flag is set to 1. However, the present invention is not limited to this, and the anti-passback violation count is reset at another timing. You may make it do.

  The center device 6 transmits a penalty message including the card ID of the IC card whose anti-passback violation number exceeds the threshold value to the entrance / exit controllers 7-1 to 7-3, and the violator possessing the card. Notification of the implementation of the restriction treatment is performed (step S206).

  The entrance / exit controllers 7-1 to 7-3 that have received the penalty message perform a restriction process set in advance for a user who has the IC card 4 with the card ID notified by the penalty message. Examples of restriction actions include: (1) warning the user, (2) prohibiting certain doors from passing, (3) prohibiting all doors from passing, (4) by card operation again Prohibiting traffic is conceivable.

  When imposing a restricted passage prohibition procedure, the entrance / exit permission information MB3 in the center device 6, the entrance / exit permission information DB31 in the entrance / exit controller 7-1, the entrance / exit permission information DB32 in the entrance / exit controller 7-2, and the entrance / exit controller 7- 3 may be changed to restrict the passage of the user who owns the card. When the restriction procedure prohibiting traffic is imposed, the user contacts the administrator to cancel the restriction treatment. In addition, when the passage by the card operation is prohibited, the restriction treatment may be canceled if no anti-passback violation occurs for a certain period.

  As described above, in this embodiment, by counting the number of anti-passback violations for each card (for each user), the system administrator identifies the violators who enter and leave the room without regularly observing operations. can do. In this embodiment, the entry / exit permission information of the violator is dynamically changed to restrict the violator from entering or leaving the room without observing the operation by imposing a restriction measure. As a result, entrance / exit management can be thorough. Further, by setting a threshold when changing the access permission information, an anti-passback violation can be allowed for a non-malicious user and only an addict can be controlled.

  In this embodiment, the entrance / exit management system using a recording medium such as an IC card is described as an example. However, the present invention is not limited to this, and biometric information such as a user's fingerprint, face, vein, etc. Thus, the present invention can be applied to an entrance / exit management system that manages entrance / exit. In this case, the readers 1-1 to 1-18 read the biometric information of the user, and the entrance / exit controllers 7-1 to 7-3 previously registered the biometric information read by the readers 1-1 to 1-18. A user is specified by comparing and collating with biometric information.

  In this embodiment, the number of anti-passback violations is counted for all doors in the facility, but may be counted for each entrance / exit controller. In this case, the center device 6 counts the number of anti-passback violations for the door where the readers 1-1 to 1-6 under the entrance / exit controller 7-1 are installed, and separately enters the entrance / exit controller 7- Counting the number of anti-passback violations for the door where the two subordinate leaders 1-7 to 1-14 are installed, and further, the readers 1-15 to 1-18 under the entrance / exit controller 7-3 are installed. Count the number of anti-passback violations for existing doors. The center device 6 may count the number of anti-passback violations for each door in the facility.

  In the present embodiment, the center device 6 manages the number of anti-passback violations, but it is managed by each of the entrance / exit controllers 7-1 to 7-3, and each of the entrance / exit controllers 7-1 to 7-3. However, the processing described with reference to FIG. 9 may be executed independently. In this case, the entrance / exit controllers 7-1 to 7-3 count the number of anti-passback violations only for the door where the subordinate leader is installed.

  Further, in this embodiment, it is determined whether or not the number of anti-passback violations exceeds the threshold value at regular intervals. However, in step S106 in FIG. At that time, the processing of FIG. 9B may be executed in real time.

  The ratio of the number of anti-passback violations to the number of normal passes permitted by the entrance / exit controllers 7-1 to 7-3 is not simply compared with the threshold value. Users who exceed the threshold may be considered as anti-passback addicts.

  In the method of simply comparing the number of anti-passback violations with a threshold value, the number of anti-passback violations may increase as the number of traffic increases. On the other hand, according to the method of comparing the ratio of the number of anti-passback violations to the number of normal traffics with a threshold value, it is possible to grasp the tendency for each user regardless of the number of traffics. It is possible to determine whether the user is a malicious user or an addict by the rate of occurrence of back violations.

  The center device 6 and the entrance / exit controllers 7-1 to 7-3 in the present embodiment can be realized by a computer having a CPU, a storage device, and an interface, and a program for controlling these hardware resources. it can. A program for operating such a computer as the center device 6 or the entrance / exit controllers 7-1 to 7-3 is recorded in a recording medium such as a flexible disk, a CD-ROM, a DVD-ROM, or a memory card. Provided. The CPU writes the read program into the storage device, and executes the processing described in this embodiment in accordance with this program.
