Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention requires security functions such as a room for storing or manufacturing money or the like, a computer room, a data storage room, an information management room, an equipment management room, and a research laboratory. The present invention relates to a security system for a building, and more particularly to a security system including a means for releasing entry control.

[0002]

2. Description of the Related Art Various security systems have been introduced for buildings requiring a security function, and confidential information, important articles and the like are managed. For example, ID
Verification is performed using numbers or ID cards, and access to the building is controlled and regulated. Such a conventional security system does not necessarily have a high security function. For example, the ID number, card theft, etc.
In some cases, unauthorized persons may enter the building by lending.

In response to such a problem, especially when entering and leaving a confidential area (building), biological personal information such as a fingerprint is registered in advance, and only the registered person (authorized person) enters. There are things that allow you to leave.

[0004]

However, even in the above-described management system, a person attempting to gain unauthorized access through security management, for example, breaking into a security management room and releasing the security operation state. There is a need for further measures.

[0005] It is an object of the present invention to provide a security system including entry restriction releasing means capable of preventing the above-mentioned unauthorized intrusion and strengthening the defense system.

[0006]

Means for Solving the Problems and Effects of the Invention In order to solve the above-mentioned problems, a security system including an entrance restriction canceling means according to the present invention comprises a building or a building in which an entrance restriction system such as a security system is in an effective state. For an entry requester who intends to enter a predetermined area, whether or not the person is registered in advance, biological characteristics such as fingerprints and retina,
Or, an entry requester-side collating device that identifies by a discriminating means such as a card or a key input, and outputs a match-eligible signal of the entry requester when it is determined that the entry requester is a registered person; Whether the releaser who can release the entrance control system in response to the request is a registered person or not is identified by a biometric feature such as a fingerprint or a retina, or an identification means such as a card or key input, and the release is performed. Within a certain period of time from the canceller-side matching device that outputs a canceling-eligible signal when the person is determined to be a registered person, and the room-entry-requester-side matching device and the canceller-side matching device. When both of the matching qualification signals are output, a release signal is supplied to the entry control system to release the entry control system, and the entry control system is released to enable the entry requester to enter the room. Means. The features.

In this security system, in addition to the conventional identification and collation such as fingerprints, retinas, and other biometric identifications for the requester of the room, a releaser such as an administrator who can release the room control system upon receiving the request for the room. Fingerprints
Performing identification and collation such as retina and other biometric identification, and when the collation eligibility signal is output from both collation devices within a certain period of time, the provision of the entrance control system release means to enable the entry requester to enter the room, The security system is released only after the identification targets such as the biological characteristics of the entry requester and the releaser are collated together. As a result, the side that releases the entry control system can also monitor itself. in this way,
Since the cancellation is also provided on the canceler side, there is no improper operation due to intrusion into the management room or the improper operation by the canceller, and the security function is strengthened.

[0008] For example, personal information (such as the name of an entry requester) of an entry requester that has been subjected to biometric matching is output to a security room or the like where a manager (canceller) provided separately from the security area is present. On the other hand, a camera (image input means) is provided in the vicinity of the entrance requester collation device, and a person image of the entrance requester is displayed on a monitor different from the monitor X in the manager room. Y (image output means), the manager checks the personal information against the personal image, and when the check is confirmed, the manager checks the fingerprint or other identification target by the canceller-side checking device. be able to. In this case, the entry control system can be released by the entry control system release unit when the collation on the requester side and the collation on the release side are performed within a fixed time. As a result, the requester-side verification device is constantly monitored by a manager or the like, and unauthorized access to a non-permitted person due to unauthorized access to a biometric identification device, or unauthorized access by an authorized person and a non-permitted person. Intrusion is prevented. For example, when an unauthorized person such as an unauthorized intruder is projected on the camera, the manager does not perform fingerprint collation, broadcasts a message indicating that entry is not permitted by an announcement or the like by voice output means, or alerts by an alarm output means. It is also possible to emit a sound.

[0009]

Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 is a schematic diagram showing an embodiment of a security system including a room entry restriction canceling means of the present invention.

Also, the fingerprint identification device 5 has an ID for identifying an individual.
Usually, fingerprint data of the individual is stored in association with a number or the like, and a fingerprint identification unit having a numeric keypad for specifying the individual is generally used. However, in the following description, in order to avoid complication, the fingerprint identification device 5 in which the numeric keypad is omitted will be described. In addition, as a single-purpose storage structure for one person or a very small number of persons, the fingerprint can be immediately collated with one or a small number of registered fingerprint data without any personal identification such as key input.

On the other hand, in the vicinity of the single door (outside of the door) of the entry control system 1, as shown in FIG. 2, the fingerprint of the entry requester is identified and registered to check whether or not it is registered (see FIG. 2). A fingerprint identification unit 20 (entry requesting side verification device) is provided as a biometric identification device for performing the determination. The fingerprint identification unit 20 is provided with a numeric keypad and a fingerprint identification device, and can perform fingerprint collation after inputting an ID number into the numeric keypad. In addition, the fingerprint identification unit 2

Further, a display device 25 for displaying the judgment result of the fingerprint identification unit 20 and a security area when the fingerprint identification unit 20 determines that the user is a registrant are provided on one door of the entry control system 1. An electric lock 19 for enabling entry to the room 100 and an unlocking switch 4 for unlocking the electric lock 19 when leaving the security area 100 are provided. Further, a single door control board 18 as a driver for controlling the operation of the fingerprint identification unit 20, the electric lock 19, the display device 25, and the like is provided.
It is provided in a single door entry control system 1.

The control unit 3 provided in the security room 110
Receives a verification result (a verification eligible signal or a verification non-compliant signal) from the fingerprint identification unit 20 and the fingerprint identification device 5 within a certain period of time, and if both are eligible for verification, sends a release signal to the entry control system 1. What to send. Specifically, the management-side control unit 3 is provided with a system that performs operational control of the entry control system 1. That is, an application program for issuing an instruction to open and close the electric lock 19 and the like to the single door control board 18 of the entry control system 1 based on the result of the verification by the fingerprint identification unit 20 and the fingerprint identification device 5, and to operate the application Operation program is the management-side control unit 3
It is prepared for. In addition, the single door control board 18
An electric lock or the like is driven in response to a command from the control unit 10.

On the other hand, the entry control system 1 includes a control unit 10 provided on a floor different from the security area 100.
For example, in the absence of a manager, the security room 11
When the management from 0 is not performed, the control unit 10 can perform the operational control of the entry control system 1. That is, the control unit 10 is provided with the same application programs and operation programs as those of the management-side control unit 3.

Further, a central control unit 9 is connected to the control unit 10, and the central control unit 9 performs overall control together with other security systems not shown (for example, security systems on different floors). For example, information such as the expiration date of each security system or the use history is input to the central control unit 9 and manages all information on the use of each security system. It should be noted that the central control unit 9 of the collective centralized type may perform all controls including the operation of the entrance control system 1 without providing the separate control unit 10.

Next, an embodiment of the operation of the security system having the above configuration will be described below. It is assumed that the permitting person (registrant) has personal data such as a fingerprint and a key (ID number) registered and stored in the fingerprint identification unit 20 and the central control unit 9 in advance.

The security system can be divided into, for example, a daytime section and a nighttime section, and the two systems are different from each other.
Hereinafter, each system will be described. Switching between the daytime system and the nighttime system can be performed by the management-side control unit 3.

First, the daytime system is not controlled or operated from the security room 110. When the system is automatically switched to a daytime system by a switching operation in the management-side control unit 3 or by a time setting program in the control unit 10 or the like, the entry control system 1 and the management-side control unit 3 are disconnected, A series of operation controls of the entry control system 1 are performed by the control unit 10.

In this case, the collation result from the fingerprint identification unit 20 is transmitted to the control unit 10, and if the collation is qualified, the personal data stored in the central control unit 9 is checked for the expiration date and the like. After storing the history, the control unit 10
, A command signal for door unlocking is transmitted to the single door control board 18.

On the other hand, with regard to the nighttime system, the security officer 110 manages and operates the nighttime system. When the system is automatically switched to the nighttime system by a switching operation in the management-side control unit 3 or by a time setting program in the control unit 10 or the like, the entry control system 1 and the management-side control unit 3 are connected,
A series of operation control of the entry control system 1 is performed by the management-side control unit 3.
It will be done in. At this time, the connection state between the control unit 10 and the entry control system 1 is maintained, and the collation / passing history and the like are stored in the central control unit 9.

In this case, the collation result from the fingerprint identification unit 20 is transmitted to the management-side control unit 3, and when the collation is qualified,
The corresponding personal information is displayed on the monitor 3a as the personal information output means of the management-side control unit 3, and the manager checks (visually confirms) the image with the above-mentioned person image on the monitor 7 (in addition,
The output of this personal information is omitted, and the monitor 7
(Only in the following description). When the collation match is confirmed, the administrator performs fingerprint collation with the fingerprint identification device 5, and the collation result is transmitted to the management-side control unit 3. The matching result of the fingerprint identification unit 20 and the fingerprint identification device 5 is qualified and for a certain period of time (for example, 60
Only when the collation eligibility signal is transmitted to the management-side control unit 3 within a short time period, the management-side control unit 3 sends a single door control board 18 to the door control board 18 for unlocking the door. A command signal is transmitted.

Hereinafter, the configuration and operation procedure of the security system will be described in more detail. As shown in FIG. 3, the intruder A checks a fingerprint and a key (ID number) by a fingerprint identification unit 20 provided near a single door. As shown in FIG. 4, the fingerprint identification unit 20 includes a numeric keypad 23 and a fingerprint identification device 22, and the intruder A inputs a key using the numeric keypad 23, and sends a finger to the fingerprint recognition unit 21 of the fingerprint identification device 22. And input the fingerprint. The numeric keypad 23 is provided because the fingerprint information of the individual is stored in association with the ID number of the individual. When the ID number is input by the numeric keypad 23, the fingerprint information corresponding to the ID number is compared. The fingerprint information is confirmed as one (registered fingerprint information), and the actually input fingerprint information is used as the other, and the two are compared (match determination).

In the case of the daytime section, as shown in FIG. 5, the single-door control board 18 and the management-side control section 3 are not connected. The key and fingerprint information of the intruder A input to the fingerprint identification unit 20 are collated with the data registered in the fingerprint identification unit 20, and the collation result is transmitted to the control unit 10 via the single door control board 18. You. If the verification is qualified, the control unit 10 sends a command such as “door unlock” to the single door control board 18 and
8 unlocks the electric lock 19. Through the above process, the intruder A is permitted to enter the security area 100.

If the collation is invalid, the control unit 10 sends a command such as "display error message" to the single door control board 18, and the single door control board 18
An error message is displayed on the display device 25 while 9 is unlocked. In the case of exiting from the single door, it is possible to exit by operating the unlock switch 4 provided on the security area 100 side of the single door. The message displayed on the display device 25 may be, for example, one of two lamps indicating that verification is OK and the other lamp indicating that verification is not possible.

In the case of the night-time section, as shown in FIG. 6, the single-door control board 18 and the management-side control section 3 are in a connected state. The key and fingerprint information of the intruder A input to the fingerprint identification unit 20 are collated with the data registered in the fingerprint identification unit 20, and the collation result is sent to the management-side control unit 3 via the single-door control board 18. Sent. If the collation result is qualified, personal information is displayed on the monitor 3a of the management-side control unit 3. If the collation result is ineligible, the display device 25 gives an error message.

On the other hand, the person image from the camera 6 is displayed on the monitor 7 in the security room 110, and the manager can display the personal information (for example, a personalized face photograph) of the monitor 3a and the monitor 7 Is confirmed by visual collation. As described above, in a simpler system, the output of personal information by the monitor 3a can be omitted.
The manager visually checks the person image on the monitor 7, and this is sufficient when the number of entry requesters is relatively small and the manager can remember all the faces and the like of the employees. The photographing of the television camera and the monitor output of the person image may be omitted altogether, and it may be determined that the collation is appropriate if only the identification target such as a fingerprint matches. In the case of a visual collation mismatch, a signal indicating that the entry control system is not released is transmitted from the management-side control unit 3 to the door control board 18, the electric lock 19 is not unlocked, and an error message is displayed by the display device 25. In the case of visual matching, the manager causes the fingerprint identification device 5 to verify his / her fingerprint. If the administrator's fingerprint collation is inappropriate, the electric lock 19 is not unlocked as described above, and an error message is displayed on the display device 25. If the administrator's fingerprint collation is qualified, the control unit 3 sends a signal to release the entry control system to the door control board 18, the electric lock 19 is unlocked, and the intruder A enters the security area 100. It becomes possible.

Although the fingerprint collation method is a known technique, its content will be briefly described. There are various methods for fingerprint identification, for example, a feature point extraction method can be adopted. In the feature point extraction method, human
A feature point such as an end point or a branch point of a fingerprint which is said to be about 00 is extracted from the fingerprint image, and the image data is stored. The method of extracting feature points is performed by capturing a scanned image with a sequence of digital lines and thinning the pixels of such a sequence. That is, the number of links in the point sequence is calculated. For example, if the number of links is 0, it can be eliminated as an isolated point (noise). If the number of links is 1, it is extracted as an end point of a feature point. The surrounding pixels are extracted as the branch points of the feature points. If the number of connections is 2, it is a connection line (not a feature point) and is not extracted as a feature point. If the number of connections is 4 or more, it is an intersection and is not extracted as a feature point. In this manner, image data is stored for each feature point. On the other hand, similar feature point extraction is performed on the input image, and a plurality of (e.g., eight) feature points are extracted therefrom. It is determined whether or not it matches the feature point of the stored image data. In the determination method, at a certain feature point (for example, a branch point), stored registered image data and input image data of an input branch point are compared by a specific algorithm, and a threshold value (for example, the total number of pixels) is determined. If the number of matching pixels is equal to or greater than (80% of the above), it is determined that the feature points match. Then, of a plurality of (eg, eight) feature points extracted from the input image, a fixed value (eg, three)
When it is determined that the feature points match, the fingerprint matching is determined. In the feature point extraction method, it is said that, for example, if about 12 or more out of about 200 feature points match, a matching match may be made.

Next, a process from the start of collation to the entrance of the security system including the entrance control system 1 will be described with reference to the flowcharts of FIGS. FIG. 7 shows a system for the daytime part, and FIG. 8 shows a system for the nighttime part. Here, the description will be made with reference to the configuration diagrams of FIGS. 5 and 6, respectively.

In the case of the daytime system, when the requester enters the key (ID number) into the fingerprint identification unit 20 in S1 of FIG. 7, the registered ID number is compared with the registered ID number (FIG. 7). S2) If the collation does not match, an error message is issued in S3 and the single door remains unlocked. In the case of collation matching, the process proceeds to S4, where a fingerprint is input to the fingerprint identification unit 20 by the entry requester, and collation with the registered fingerprint is performed (S5). If there is a mismatch,
If an error message is issued in S3 and the single door is not unlocked, and if the verification matches, the process proceeds to S6, where the single door is unlocked and the person requesting entry is allowed to enter the security area 100 (S7).

In the case of the nighttime system, S1 to S5 in FIG.
In the same manner as in the daytime system, the requester enters the ID number in the fingerprint identification unit 20 and then the fingerprint collation. If the collation does not match, an error message is issued in S3 and the collation by the admission requester is performed. The disagreement is displayed and the single door remains unlocked. In the case of collation matching, the process proceeds to S6, and the personal information of the requester of the room identified by the fingerprint identification unit 20 is displayed on the monitor 3a of the management-side control unit 3.

On the other hand, a video of the person requesting entry is transmitted from the camera 6 to the monitor 7 of the security room 110 (S7), and in S8, the entry control system 1, that is, an administrator who can unlock the electric lock 19 of one door (released) Person) performs visual collation of the person image. Further, in S9, the person image on the monitor 7 is compared with the personal information on the monitor 3a. If the two do not match, an error message is issued in S3,
The single door remains unlocked.

In the case of collation matching, the process proceeds to S10, where a fingerprint is input to the fingerprint identification device 5 by the administrator, the fingerprint collation is performed in S11, and if the collation does not match, an error message is performed in S12, and the canceler side Is displayed on the monitor 3a and the display device 25, and the single door remains unlocked. In the case of collation matching, the process proceeds to S13, where it is determined whether or not the fingerprint input from the requester of the entry requester in S4 to the releaser in S10 has been performed within a predetermined time (for example, about 60 seconds). If the time is exceeded, an error message is issued in S14 and the monitor 3 reports that the time has been exceeded.
a and the display device 25, and the single door remains unlocked.

In S13, if it is confirmed that a series of operations in S4 to S10 have been performed within a predetermined time, the process proceeds to S15, where the management-side control unit 3 releases the entry control system to the single-door control board 18. Is transmitted, the one-door control board 18 unlocks the electric lock 19 (S16), and the intruder A can enter the security area 100 (S17).

The above messages and error messages may be displayed on the display device 25, or a speaker as a sound output means may be provided in the vicinity of the entry control system 1, and may be issued by an administrator's announcement or the like. .

In the security system including the above-described entry control system 1, the entry control system 1 (particularly, the fingerprint identification unit 20) is constantly monitored by a manager or the like, and unauthorized use of the biometric identification device by unauthorized use is prohibited. Entering the room,
Alternatively, unauthorized entry into the accompanying room or the like by an authorized person and a non-authorized person is reliably prevented, and since the collaborator is also provided on the canceller side, there is no fraud from the canceller side, and the crime prevention system is strengthened.

The apparatus for performing personal identification is not limited to a biometric identification device for collating a fingerprint as in the present embodiment, but may be an apparatus for identifying another biological characteristic such as a retina or a voiceprint. It is also possible to employ a device for performing personal identification using personal identification means such as a card and a key.

Further, in this embodiment, the security system including the entry restriction canceling means is used in combination with the daytime section and the nighttime section. It is also possible to operate the management-side control unit 3 as a means. Further, if a collation history storage unit is provided in the canceller-side collation device and personal information such as the name of the person who has canceled the entry control system is stored, the security of the building is further enhanced.

Further, as a simpler system, the image of the entry requester is not photographed by a television camera at all, and the identification and collation of the entry requester are judged to be coincident by the collation system (program or the like). If the collation system (a program or the like) also determines that the identification and collation of the person who has canceled the request is the same, a cancellation signal may be output so that the person requesting entry can enter the room.
