Referring to FIG. 1 , the security enhancement device 100 for tail gating receives and analyzes an image captured by an image capturing device.

An image capturing apparatus is a device capable of capturing an image, such as a camera or CCTV. The image capturing apparatus may exist in various locations, but may exist in a location capable of photographing a person entering the door of the security location 10 and a person tagging a pass on the pass reader 20 .

That is, the security enhancement apparatus 100 for tail gating may receive images from a plurality of image photographing apparatuses existing in various locations. In addition, the security enhancement apparatus 100 for tail gating may receive an image from an image photographing apparatus photographing a person entering the door of the security location 10 . Also, the security enhancement apparatus 100 for tail gating may receive an image from an image photographing apparatus that photographs a person who tags a pass on the pass reader 20 .

In FIG. 1 , an image photographed by the first image photographing apparatus 50 , which is an image photographing apparatus for photographing a person entering the door of the security place 10 , may be transmitted to the security enhancement apparatus 100 for tail gating.

In FIG. 1 , the first entrant 30 enters the secure location 10 using his/her legitimate first pass 31 . The second entrant 40 follows the first entrant 30 without being authenticated using the second pass 41 he possesses (Tail Gating).

The pass reader 20 may obtain information on the pass and transmit the obtained information to the security enhancement device 100 for tail gating.

The apparatus 100 for enhancing security for tail gating may obtain various types of information by comparing the pass information with information stored in the database 300 .

The database 300 may be a physical device separate from the security enhancement device 100 for tail gating. Alternatively, a storage space inside the security enhancement device 100 for tail gating instead of a separate physical device may perform the same role as the database 300 .

In the database 300 , information (eg, name, department, photo, contact information, etc.) of a valid holder of the pass may be stored in matching with information on the pass (eg, pass identifier information).

Information (eg, the name, department, photo, contact information, etc. of a person authorized to enter) may be stored for each security location 10 .

The pass may be a variety of devices used to access the secure place 10, such as an employee ID, a visitor pass, and a terminal in which a specific application is installed.

The IPS server 200 is a server that checks the location of a pass using indoor positioning systems (IPS).

The IPS server 200 may check the location of a pass, such as an employee ID, a visitor ID, and a terminal in which a specific application is installed, and transmit it to the security enhancement device 100 for tail gating.

Continuing to refer to FIG. 1 , the second pass 41 possessed by the second entrant 40 may not be the pass of the second entrant 40 , and a pass not authorized to enter the secure location 10 . it may be Alternatively, the second entrant 40 may not have a pass.

The apparatus 100 for enhancing security for tail gating according to an embodiment of the present invention may strengthen security and response to tail gating in preparation for all such cases.

The security enhancement device 100 for tail gating according to an embodiment of the present invention will be described in more detail with reference to FIG. 2 .

2 is a block diagram illustrating an example of an apparatus for enhancing security for tail gating according to an embodiment of the present invention.

Referring to FIG. 2 , the apparatus 100 for enhancing security for tail gating according to an embodiment of the present invention includes an image analysis unit 110 , an information comparison unit 120 , and a warning providing unit 130 .

The image analysis unit 110 receives an image from the image capturing apparatus and analyzes the received image.

Specifically, the image analysis unit 110 may analyze the face of a person entering the secure place through tail gating in the image.

The image analysis unit 110 determines whether or not there is a person entering the secure place by tail gating. If the number of times the pass is used to enter the secure place for a predetermined time and the number of people entering the secure place are different, it is determined by tail gating. It can be determined that a person who has entered the secure area is present.

The image analysis unit 110 may analyze the faces of people entering the secure place by using the image.

For example, the image analyzer 110 may analyze faces existing in the image to obtain information on facial feature points.

The information comparison unit 120 compares the analyzed face information (eg, information about facial feature points) with the face information stored in the database 300 to obtain matching information.

The matching information obtained by the information comparison unit 120 may be information about a person photographed in an image.

The information about the person may include information about the person's name, department, photo, contact information, accessible secure location and/or pass identifier.

The information comparison unit 120 may determine a person other than a person matching a pass used for entering a secure place among the obtained matching information as a person entering the tail gating.

Subsequently, the information comparison unit 120 determines whether the person who entered the tail gating has the right to enter the security place entered through the tail gating using the information about the person who entered the tail gating obtained by comparing and matching. can determine whether

Referring to FIG. 1 , the person who enters the secure location by tail gating in FIG. 1 is the second entrant 40 . The image analysis unit 110 analyzes the faces of the first entrant 30 and the second entrant 40 .

The information comparison unit 120 obtains information matching each face information from the database 300 by using the analyzed face information.

The information comparison unit 120 may determine the second entrant 40 as a person who entered the tail gating except for the first entrant 30 matching the first pass 31 from among the acquired information.

The information comparison unit 120 determines whether the person who entered the tail gating has the right to enter the secure place by using the information stored in the data ace and the image analysis information.

As a result of the determination, the warning providing unit 130 may not provide a warning to the security officer when the person who entered the tail gating has the right to enter the secure place.

That is, the warning providing unit 130 may warn the security officer that an intruder has occurred in the secure place when the person who entered the tail gating does not have the right to enter the secure place as a result of the determination.

The warning providing unit 130 may also provide information on which security location an intruder has occurred to the security officer by using the image analysis information and/or the location information of the image capturing device.

For example, if tail gating of a person who is not authorized to enter Area A on the 2nd floor is detected in the video obtained from CCTV that is filming the security location of Area A on the 2nd floor, an intruder has occurred in Area A on the 2nd floor may provide location information.

In addition, facial information about a person who has entered tail gating can also be provided to the security officer.

Another embodiment in which the security enhancement apparatus 100 for tail gating according to an embodiment of the present invention enhances security for tail gating will be described.

In the case of a person entering through tail gating, there are many cases of entering in a state close to the person who entered earlier. Accordingly, there are cases in which a person entering into tail gating overlaps or is covered with a person who has previously entered, so that the image is not captured enough to be analyzed by the image capturing apparatus.

In preparation for this case, the information comparison unit 120 may further enhance security by using the indoor location of the pass confirmed by the IPS server 200 .

In detail, continuing with reference to FIG. 2 , the image analysis unit 110 analyzes an image including a person who has entered tail gating. The image analysis unit 110 may determine that it is impossible to analyze the image of a person who enters tail gating to a level at which the information stored in the image analysis result database 300 and the image analysis information can be compared.

For example, the image analysis unit 110 fails to acquire the feature points of the face of the person who enters tail gating due to overlap between people, the shooting angle, etc., or the information stored in the database 300 is insufficient even if some feature points are acquired By comparison, matching information may not be obtained.

When the image analysis unit 110 fails to obtain information on a person who has entered tail gating, the information comparison unit 120 may obtain an indoor location identified for each pass from the IPS server 200 .

Specifically, it is possible to acquire the indoor location for each pass confirmed at the point in time when a person who enters the security area through tail gating enters or at the point closest to the point of entry.

More specifically, the information comparison unit 120 analyzes the image to determine the location of the person who entered the tail gating.

In addition, the information comparison unit 120 determines that a pass that exists within a preset range from a location where a person who has entered the determined tail gating exists among the acquired indoor locations for each pass as a pass possessed by a person who enters through tail gating. can

If there are a plurality of pass passes within a preset range, the person who enters the tail gating checks the location of the pass used just before entering the secure place. The location of the pass used just before entering the secure area may use indoor positioning technology.

Alternatively, the location of the pass used just before entering the secure place may be determined using image analysis information, pass usage history, and/or the location of the pass reader 20 .

The information comparison unit 120 may determine the pass closest to the location of the pass used just before entering the secure place among pass existing within a preset range as the pass of the person who entered through tail gating.

If there are a plurality of people who have entered tail gating, the information comparison unit 120 may determine the plurality of passes as the pass corresponding to the plurality of people in the order of proximity to the location of the pass used immediately before the determined entry. .

The warning providing unit 130 obtains, from the database 300 , information on a person matching the pass information possessed by a person who entered tail gating acquired by the information comparison unit 120 .

The warning providing unit 130 may warn the security officer that an intruder has occurred in the secure place only when the person matching the pass information does not have the right to enter the secure place.

When warning that an intruder has occurred in a secure place, the warning providing unit 130 may continuously provide location information of a pass possessed by a person who has entered tail gating, which is checked using indoor location verification technology, to the security officer. .

The tail gating security enhancement apparatus according to an embodiment of the present invention may further include an image capturing apparatus controller (not shown).

When there is a person who enters the secure place by tail gating, the image capturing device controller may photograph the secure place or control the image capturing device existing in the secure place to have a higher quality than usual.

The security enhancement apparatus 100 for tail gating according to an embodiment of the present invention described with reference to FIGS. 1 and 2 may not necessarily enhance security and response to a person who enters tail gating.

It can also be used when entering a secure area using someone else's pass instead of tail gating.

More specifically, the image analysis unit 110 analyzes an image of a person who has entered the secure place using a pass authorized to enter.

The information comparison unit 120 compares the information obtained by analyzing the image with the information of the database 300 in which information about the person who has the right to possess for each pass is stored.

As a result of the comparison, if the person who entered the secure place does not have the right to possess the pass used to enter the secure place, the warning providing unit 130 may provide a warning about the presence of an intruder to the security officer and the location information of the pass. .

However, as a result of comparing the information stored in the database 300 with the image analysis information, even if the person who entered the secure place does not have the right to possess the pass used to enter the secure place as a result of the comparison, the person who entered the security When the place entry right exists, the warning providing unit 130 may not provide a warning to the security officer. Alternatively, in this case, the warning providing unit 130 may provide a low level warning to the security officer. For example, it could warn of the presence of someone who is not an intruder but has someone else's pass.

3 is a diagram illustrating an example of a hardware configuration of an apparatus for enhancing security for tail gating according to an embodiment of the present invention.

The security enhancement apparatus 100 for tail gating according to the present embodiment may have the configuration of FIG. 3 .

As shown in FIG. 3 , the security enhancement device 100 for tail gating may include a security enhancement processor 61 for tail gating, storage 62 , memory 63 , and a network interface 64 . .

In addition, the security enhancement device 100 for tail gating may include a system bus 65 that is connected to the security enhancement processor 61 and the memory 63 for tail gating and serves as a data movement path.

Another computing device may be connected to the network interface 64 . For example, another computing device connected to the network interface 64 may be a display device, a user terminal, or the like.

The network interface 64 may be Ethernet, FireWire, USB, or the like.

The storage 62 may be implemented as a non-volatile memory device such as a flash memory, a hard disk, or the like, but is not limited thereto.

The storage 62 stores data of the computer program 21 for enhancing security for tail gating. The data of the computer program 21 for enhancing security for tail gating may include binary executable files and other resource files.

The security enhancement processor 61 for tail gating is a processor capable of executing the computer program 21 for security enhancement for tail gating. However, the security enhancement processor 61 for tail gating may not be a processor capable of executing only the computer program 21 for tail gating security enhancement. For example, the security enhancement processor 61 for tail gating may execute a program other than the computer program 21 for security enhancement for tail gating.

A computer program for strengthening security for tail gating ( 21) is a process of analyzing an image of a person who has entered the tail gating, a process of comparing the information obtained by analyzing the image with information about a database 300 storing information about a person authorized to enter the secure place, and As a result of the comparison, when it is determined that the person who has entered the tail gating is not authorized to enter the secure place, a series of operations of providing a warning to a security officer may be included.

Hereinafter, a security enhancement method for tail gating according to another embodiment of the present invention will be described with reference to FIGS. 4 to 7 . The present embodiment may be performed by a computing device having an arithmetic unit. The computing device may be, for example, the security enhancement device 100 for tail gating according to an embodiment of the present invention. The configuration and operation of the security enhancement device 100 for the tail gating can be understood through the descriptions with reference to FIGS. 1 to 3 .

Similarly, the contents described with reference to FIGS. 4 to 7 may also be applied to the apparatus 100 for enhancing security for tail gating according to an embodiment of the present invention.

4 is a flowchart of a method for enhancing security for tail gating according to another embodiment of the present invention.

Referring to FIG. 4 , the computing device detects a person entering the secure place by tail gating by analyzing the image captured by the image capturing device for photographing a person entering the secure place ( S110 ).

The computing device analyzes the image to obtain face information of a person who has entered tail gating ( S120 ).

The computing device acquires information matching face information of a person who has entered tail gating from among face information stored in the database 300 . The computing device acquires information about the right to enter the secure place stored in the database 300 in association with the matching information (S130). That is, the computing device may analyze face information of a person who has entered tail gating from the image, and may obtain information about a person matching the analyzed face information from information stored in the database 300 . The information about the person matching the analyzed face information may include a photo, name, department, position, accessible security location, pass ID, contact information, and the like of the matching person.

The computing device determines whether or not the person having the face information of the person who entered the tail gating has the right to enter the secure place by using the obtained information on the entry right (S140).

The computing device warns the security officer that an intruder exists in the secure place when the person who has entered the tail gating does not have the right to enter the secure place as a result of the determination ( S150 ). Specifically, the computing device may provide a warning to the display device being monitored by the security officer and the security officer terminal 400 . The warning provided to the security officer may include visual and audible information.

5 is a flowchart of another embodiment of a method for enhancing security for tail gating according to another embodiment of the present invention.

Referring to FIG. 5 , when the computing device can analyze the face of a person who has entered tail gating from the image, the computing device may operate as described with reference to FIG. 4 . That is, the image is analyzed to obtain human face information, and when information about a person matching the obtained human face information from information stored in the database 300 can be obtained, operations are performed in the order of S160, S130, S140 and S150. can do.

However, when the computing device cannot analyze the face of the person who entered the tail gating from the image, or there is no information about the person matching the database 300 even though the face can be analyzed (ex. an external intruder) (S160) ) The pass possessed by the person who entered the tail gating is determined using indoor positioning technology (S170).

A typical case in which the face of a person entering through tail gating cannot be analyzed is a case in which a person entering through tail gating is obscured by others.

The computing device checks the authority of the pass possessed by the person who entered the tail gating from the information stored in the database 300 (S180).

The computing device does not provide a warning to the security officer when the pass possessed by the person who has entered the tail gating has the right to enter the secure place ( S190 ).

When the computing device provides a warning to the security officer ( S150 ), the computing device may also provide information on the location of the person who entered the tail gating.

6 is a diagram illustrating an example of providing information on a location of a person who has entered tail gating.

Referring to FIG. 6 , when the computing device determines that the person who entered the tail gating using the image analysis is not authorized to enter the secure place, the location or image in which the image photographing device photographing the image used for the image analysis is installed Information regarding the location of the person who entered the tail gating confirmed through analysis may be provided to the security officer (S152).

Alternatively, the computing device tracks the location of a pass, such as a visitor pass, an employee ID, a terminal in which a specific application is installed, etc. possessed by a person who has entered tail gating using an indoor positioning technology, and provides the tracked location information to the security officer It can be done (S154).

An example of a method for the computing device to determine a pass possessed by a person who has entered tail gating will be described with reference to FIG. 7 .

7 is a view for explaining an example of a method of determining a pass possessed by a person who has entered tail gating.

Referring to FIG. 7 , a building having different security locations for each floor is shown.

In the database 300, information (eg, name, department, contact information, pass ID, photo, facial features, etc.) about a person who has the right to enter for each secure place is stored.

To explain the situation on the second floor of FIG. 7 , the first person 74c is entering the security location 72 on the second floor using his or her valid pass 75c. When the first person 74c enters the secure location 72, the second person 74d follows the first person 74c without performing authentication with his or her pass 75d (Tail Gating). .

The second image capturing device 76b for photographing a person entering the second-floor security location 72 photographs the first person 74c and the second person 74d entering the second-floor security location 72 . The captured image is transmitted to a computing device (eg, the security enhancement device 100 for tail gating).

The IPS server 200 may check the location of each of the pass passes 75a, 75c, 75d, 75e, 75g, 75h in the building using indoor positioning technology.

The IPS server 200 transmits the location of each of the verified pass passes to the computing device (eg, the security enhancement device 100 for tail gating).

The computing device may determine the closest pass among pass existing within a preset range at the reference position as the pass possessed by a person entering through tail gating.

The reference position may be, for example, the position of the pass 75c used to enter the second-floor security area 72 . In this case, the pass possessed by the person entering the tail gating may be the pass 75d that is closest to the pass 75c.

Alternatively, the reference position may be the position of the pass reader 20 located in the second floor security area 72 .

Alternatively, the reference position may be the position of a person entering the tail gating analyzed by the second image capturing apparatus 76b. The position of a person entering the tail gating can be identified even when facial features are not clearly analyzed by image analysis.

If it is determined by the image analysis that the person 74d who has entered the tail gating exists but the pass that is determined to be possessed by the person 74d who has entered the tail gating does not exist, the computing device warns the security officer can provide

However, when the face analysis of the person 74d who has entered tail gating through image analysis is possible, the computing device determines whether the person 74d who entered tail gating has the authority to enter the second floor security place in the database 300 ) can be identified using the information stored in The computing device may not provide an alert to the security officer if it is determined that it is authorized to enter the secure location. This is because, in this case, the person 74d who has entered the tail gating may simply leave the pass inside the security place and leave.

The security enhancement method for tail gating according to another embodiment of the present invention described with reference to FIGS. 4 to 7 is not necessarily capable of strengthening security and response to a person who enters tail gating.
