Description

Illegal ride detection system and method using irreversible function to protect privacy by using irreversible function

The present invention relates to a system and method for detecting illegal rides in a subway, etc., and specifically, it is possible to prevent privacy infringement by detecting illegal rides through an emergency gate while encrypting the face information of the visitor using an irreversible function. It relates to an illegal ride detection system and method.

Types of illegal rides on subways and urban railroads include unauthorized passage through ticket gates, unauthorized passage through emergency gates, and use of preferential tickets for others (e.g., student, disabled, senior citizens) It is very diverse, such as.

The type of unauthorized passage through the ticket gate is the type of jumping over or crawling down the barrier of the ticket gate, and the type of unauthorized passage through the emergency gate is a lie that there is urgent business such as a toilet and disappears or disappears as it is after passing through the emergency gate. It is a type of unauthorized opening or passing through the door of the gate.

In most subway stations, as shown in FIG. 1, an emergency gate 20 is installed next to the outermost ticket gate 10, and an interphone 25 for making a call with a station attendant is installed at the emergency gate 20. Has been. When the passenger presses the interphone 25, the bell rings inside the office where the station attendant works, and when the station attendant presses the open button remotely, the lock 23 of the emergency gate 20 is released, allowing the door 21 to be opened. .

However, from the standpoint of the station attendant, even if the person who pressed the intercom 25 lies, there is no way to check it, so when the bell rings, the door 21 has to be opened after a formal question. Even if the bell rings, the door 21 may be opened without asking any questions, and the door 21 may be left open at all because it is annoying at times when the bell rings frequently.

In addition, from the standpoint of illegal passengers, in order to pass through the official ticket gate 10 without permission, there is a burden of having to take an abnormal posture, such as jumping over a barrier or climbing the floor, but the emergency gate 20 can pass by walking normally if you lie only once. Because of this, a person who has experienced one wrong ride through the emergency gate 20 tends to use it repeatedly.

For this reason, it has been reported that the number of illegal rides through emergency gates has increased rapidly in recent years, and there is an urgent need to prepare measures to prevent this.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

For reference, in the present specification, when one element is connected, combined, or communicated with another element, not only the case of direct connection, coupling, or communication with another element, but also another element in the middle This includes cases of indirect connection, association, or communication over and over. In addition, when a certain part includes or includes a certain component, it means that other components may be further included or provided, rather than excluding other components, unless specifically stated to the contrary. In addition, since the drawings attached to the present specification are merely illustrative for easy understanding of the subject matter of the invention, it should be noted in advance that the scope of the present invention should not be limitedly interpreted.

An illegal ride detection system according to an embodiment of the present invention, as shown in the schematic configuration diagram of FIG. 2, an illegal ride monitoring device 100 installed on one side of the emergency gate 20, a plurality of illegal ride monitoring devices 100 ) And the communication network 50 may include a server 200 that communicates.

Hereinafter, the illegal riding monitoring apparatus 100 and the server 200 will be described in more detail with reference to FIGS. 3 and 4.

Unauthorized riding monitoring device 100, as shown in the schematic configuration diagram of Fig. 3, a first camera (110a), a second camera (110b), encryption code generation unit 120, display 130, input unit 140 ), a first determination unit 150, a second determination unit 160, a door control unit 170, a communication unit 180, a storage unit 190, a control unit 102, and the like.

The illegal ride monitoring device 100 may be in the shape of a kiosk erected on one side of the emergency gate 20, as shown in FIG. 2. However, of course, the specific shape is not necessarily limited thereto.

The first camera 110a is installed in the illegal ride monitoring device 100 and may be used for obtaining face image data of a person who uses the illegal ride monitoring device 100. However, since it is not limited thereto, body image data may be obtained by photographing the body of the user of the emergency gate 20.

The second camera 110b may be installed on the emergency gate 20 and used to obtain body image data of a person passing through the emergency gate 20. It is preferable that the second camera 110b acquires body image data by photographing not only a person who normally passes through the emergency gate 20 but also a person who jumps or crawls downward.

When the second camera 110b captures a body image, it is preferable to also take a facial image. In this way, when the second determination unit 160 determines that the person is an illegal rider through posture analysis, the password extracted from the person's facial information By transmitting the code to the server 200, it is possible to register as an illegal passenger.

In the drawing, it is shown that there is only one second camera 110b, but in order to photograph both an incoming and outgoing person, it is preferable to include a camera that photographs from the incoming direction through the emergency gate 20 and a camera that photographs from the exit direction, respectively. Do. Accordingly, in FIGS. 2 and 3, the second camera 110b may include a plurality of cameras installed in different directions, respectively.

If the first camera 110a and the second camera 110b are separately installed as described above, there is an advantage in that the person entering the emergency gate 20 can be more accurately photographed. However, the present invention is not limited thereto, and only one of the first camera 110a and the second camera 110b may be installed if necessary.

The encryption code generator 120 extracts feature information from the face image and/or body image acquired through the first camera 110a and/or the second camera 110b, and uses the extracted feature information to use the emergency gate ( 20) Generate an irreversible encryption code for the visitor's facial information and/or posture information.

The irreversible encryption code is a digital data of facial information and/or posture information acquired through the cameras 110a and 110b is encrypted using an irreversible function. Once converted into an irreversible encryption code, the original facial information Since it is impossible to extract posture information, there is an advantage of fundamentally blocking the leakage of personal information such as faces of visitors.

The feature information of the face image may include information on a plurality of feature points defined in the face image, as shown in FIG. 5. The feature points of the face may be set, for example, at the ends of the eyes, the tip of the nose, the tail of the mouth, the cheekbones, the chin, and the eyebrows.

In addition, the characteristic information of the body image may include information on a plurality of characteristic points defined in the body. Characteristic points of the body may be set in arms, legs, trunk, head, and various joints (neck, wrist, ankle, elbow, knee, shoulder, pelvis, etc.) as shown in FIG. 6, for example.

The control unit 102 transmits the encryption code generated by the encryption code generation unit 120 to the server 200, and the comparison analysis unit 210 of the server 200 retrieves the received encryption code from a search requester DB (Fig. 220) and the code stored in the illegal passenger DB (refer to 230 in FIG. 4), it is determined whether the user is a search requester or a person who has experienced illegal riding.

In the embodiment of the present invention, it is shown that the encryption code generation unit 120 generates encryption codes for face information and posture information, but is not limited thereto. If necessary, only an encryption code for facial information may be generated, or only an encryption code for posture information may be generated.

The display 130 displays the emergency gate usage manual and instructions to the emergency gate 20 user. If there is no person using the emergency gate 20, it may serve to display an advertisement image or a promotional image.

The input unit 140 may be provided in the form of a touch screen, a touch pad, and a keypad.

Although not shown in the drawing, a speaker for outputting various guides and instructions to users of the emergency gate 20 may be installed in the illegal ride monitoring device 100. Warning sirens or beacons may be installed.

The first determination unit 150 and the second determination unit 160 are used to determine whether or not to ride illegally.

The first determination unit 150 checks whether a person who has passed through the emergency gate 20 due to an urgent business returns or not, and determines whether or not to ride illegally.

For example, when a person who has passed through the emergency gate 20 returns within a set time (eg, 20 minutes), the first determination unit 150 deletes all temporarily stored information and locks the device 23 through the door control unit 170. ) Is released. On the contrary, if it does not return within the set time, it is determined that the vehicle has been illegally boarded, and related information such as the encryption code of the facial information of the illegal passenger, the transit time, the subway station name, and the gate number may be transmitted to the server 200 and stored.

The second determination unit 160 may determine whether or not to ride illegally after acquiring body images of everyone passing through the emergency gate 20 through the second camera 110b.

As an example, when a posture analysis is performed from the acquired body image and a posture jumping over or crawling under the door 21 of the emergency gate is detected as illustrated in FIGS. 7 and 8, it may be determined as an illegal passenger. have.

A method of determining whether or not to ride illegally through posture analysis is not particularly limited. As an example, if the position value function f(P1, P2, ..., Pn) of a plurality of feature points defined in the body falls within an arbitrary range as follows, it may be determined as normal.

MIN ≤ f(P1, P2, ..., Pn) ≤ MAX

On the other hand, if f(P1, P2, ..., Pn) <MIN, or f(P1, P2, ..., Pn)> MAX, it is regarded as an abnormal posture and can be judged as an illegal ride.

A machine learning algorithm, such as deep learning, may be applied to the second determination unit 160 to determine whether or not to ride illegally through image pattern analysis.

Meanwhile, the second determination unit 160 may determine whether or not a person passing through the emergency gate 20 without permission by pretending to be a party with a person who normally passes through the emergency gate 20. Specifically, the facial information encryption code is compared with the facial information encryption code of the person passing through the emergency gate obtained through the first camera 110a and the facial information encryption code of the person entering the emergency gate obtained through the second camera 110b. When a person who does not match passes through the emergency gate, a warning may be generated and the corresponding facial information encryption code may be transmitted to the server 200 to be registered as an illegal passenger.

When the second determination unit 160 determines an illegal rider, the irreversible encryption code extracted from the facial image acquired by the second camera 110b, and related information such as transit time, subway station name, and gate number are sent to the server 200 together. Can be sent and saved. Of course, if it is determined that it is not an illegal driver, all temporarily stored information must be immediately deleted.

Meanwhile, the second determination unit 160 may be installed only on the server 200 without being installed on the illegal riding monitoring device 100. That is, the posture determination unit (240 in FIG. 4) of the server 200 may serve as the second determination unit 160.

The door control unit 170 serves to open the door 21 by releasing the locking device 23 of the emergency gate 20 when there is a request for passage from the user. However, it is preferable to release the locking device 23 only when it is confirmed that the encryption code generated by the encryption code generation unit 120 is not a code registered as an illegal passenger in the server 200.

The door control unit 170 serves to open the door 21 by releasing the locking device 23 even when a person who has passed through the emergency gate 20 completes an urgent business and requests a return. In this case, the door 21 is opened only in the case of converting the returnee's facial image taken through the first camera 110a or the second camera 110b into an encryption code and then temporarily stored in the same as the pass requester's password code. It is desirable.

It is preferable that the door 21 is an automatic opening/closing type.

The communication unit 180 provides a communication interface with a wireless communication network or a wired communication network. In the drawing, it is shown that the illegal ride monitoring device 100 communicates with the server 200 through the communication network 50, but is not limited thereto, and thus a communication interface with a terminal used by a station attendant or a terminal used by an administrator can be provided. May be.

The storage unit 190 stores various applications required for the operation of the illegal ride monitoring device 100. In addition, the storage unit 190 temporarily stores an encryption code for facial information and posture information generated by the encryption code generation unit 120.

The control unit 102 controls the overall operation of the illegal ride monitoring device 100. That is, when the camera (110a, 110b) captures the face image and posture image of the visitor, the control unit 102 controls the encryption code generator 120 to generate an encryption code for the face image and posture image, and the server 200 ).

In addition, when receiving a response from the server 200 indicating that the code does not match the code registered in the illegal passenger DB 230, the control unit 102 controls the door control unit 170 to open the door 21 of the emergency gate 20.

The encryption code generation unit 120, the first determination unit 150, the second determination unit 160, the door control unit 170, and the control unit 102 of the illegal ride monitoring device 100 are each using separate software. It may be implemented, or two or more functions may be integrated and implemented in one software. Also, at least one functional unit may be implemented in combination with hardware.

Meanwhile, although not shown in the drawings, the illegal ride monitoring device 100 may include an intelligent user interface such as a chatbot.

The server 200 is a comparison and analysis unit 210, a search requester DB 220, an illegal rider DB 230, an attitude determination unit 240, an alarm generator 250, as shown in the schematic configuration diagram of FIG. , A communication unit 260, a control unit 202, and the like.

The comparison and analysis unit 210 determines whether the encryption code received from the illegal ride monitoring device 100 matches the encryption code stored in the search requestor DB 220 or the illegal ride DB 230, and determines the result of the illegal ride. It is transmitted to the monitoring device 100.

The comparison and analysis unit 240 may determine that the data string of the encryption code received from the illegal ride monitoring device 100 is 100% identical to the data string of the encryption code stored in the server 200 to match each other. Otherwise, if they are equal to or greater than a set percentage, they may be determined to be consistent with each other, or may be determined by applying other methods.

The comparison and analysis unit 210 may determine whether or not the encryption codes match using a machine learning algorithm.

In the search requester DB 220, face information of a criminal, a wanted person, etc. is stored as an encryption code converted by an irreversible function. To this end, the server 200 according to an embodiment of the present invention may include an encryption code generation unit (not shown in the drawing) that converts the face image of the search requester received from the National Police Agency server into an encryption code using an irreversible function. have.

In the illegal passenger DB 230, facial information of the illegal passenger is stored as an encryption code converted by an irreversible function. For example, facial information of a person who is determined to be an illegal ride by the illegal ride determination unit 160 of the illegal ride monitoring device 100 is stored as an encryption code in the illegal ride DB 230.

The posture determination unit 240 performs the same role as the second determination unit 160 of the illegal riding monitoring device 100. Therefore, it is determined whether the posture of jumping over the door (or barrier bar) or crawling down, rather than opening the door of the emergency gate, corresponds to an illegal ride.

When the posture determination unit 240 determines that the posture information received from the illegal ride monitoring device 100 corresponds to an illegal ride, the server 200 transmits the fact to the illegal ride monitoring device 100. In addition, the illegal ride monitoring device 100 transmits the irreversible encryption code converted from the facial information of the illegal passenger to the server 200 along with related information such as the time of entry, the subway station name, and the gate number, and the server 200 If a person is newly registered in the illegal passenger DB 230 or is already registered, the corresponding information is updated.

When the comparison and analysis unit 210 determines that the received encryption code matches the one stored in the illegal passenger DB 230, the illegal passenger DB 230 updates the information corresponding to the code, that is, the emergency gate transit request time. , Subway station name, gate number, etc. are mapped and stored with the corresponding code.

In addition, when it is determined that the received encryption code matches the one stored in the search requester DB 220, the comparison and analysis unit 210 may control the alarm generating unit 250 to transmit an alarm to a police agency server or a station attendant terminal. Alerts can include predetermined messages.

The comparison and analysis unit 210, the posture determination unit 240, the alarm generation unit 250, and the control unit 202 of the server 200 may be implemented by separate software, or two or more functions in one software. Can also be implemented in combination. Also, at least one functional unit may be implemented in combination with hardware.

Hereinafter, a method for detecting an illegal ride according to an embodiment of the present invention will be described with reference to FIG. 9 and the above-described drawings.

First, a person who wants to see an urgent business by passing through the emergency gate 20 must stand in front of the illegal riding monitoring device 100 as shown in FIG. 2 and input a request for use. For example, as shown in FIG. 10 (a), a request for use may be input by pressing the'pass' button displayed on the display 130. (ST11)

When a request for use is input, the controller 102 of the illegal ride monitoring device 100 controls the first camera 110a to take a picture of the requestor's face. At this time, as illustrated in FIG. 10(b), a guide saying "Take a picture of your face. Look at the front" may be displayed on the display 130 or a voice may be output through a speaker. In addition, the requestor's face image may be displayed on the display 130 for accurate photographing. (ST12)

When a face is photographed through the first camera 110a, the encryption code generation unit 120 of the illegal ride monitoring device 100 generates an irreversible encryption code from the feature points of the facial image and stores the generated encryption code in the server 200. Transfer to. (ST13, ST14)

The comparison and analysis unit 210 of the server 200 checks whether a code matching the encryption code received in the search requestor DB 220 and the illegal passenger DB 230 is registered, and the server 200 checks the result Is transmitted to the illegal riding monitoring device 100. (ST15)

When it is confirmed that the requestor's encryption code is not registered in the server 200, the door control unit 170 releases the locking device 23 of the emergency gate 20. At this time, as illustrated in FIG. 10(c), an announcement such as "The door is open. Please complete the business within 20 minutes and press the return button" or the same content is voiced through the speaker. You may. (ST16)

Meanwhile, the first determination unit 150 counts from the time the locking device 23 is released, and determines whether the'return' button is pressed within a set time (eg, 20 minutes) as illustrated in FIG. 10(d). Watch. At this time, there are cases where another person presses the'return' button, so in order to accurately determine whether the return is not performed, when the'return' button is pressed, the face of the person who pressed the return button is photographed using the first camera 110a and an irreversible encryption code And when the generated encryption code matches the temporarily stored encryption code, it can be determined that it has returned only when the return button is pressed within a set time.

That is, even if the password code of the returning person coincides with the temporarily stored password code, if the return button is pressed beyond the set time, it may be determined as an illegal passenger. (ST17)

As a result of the above determination, if it is determined that the emergency gate user has returned within the set time, the control unit 102 discards personal information by deleting all the temporarily stored user's face image and password code, while a lock device through the door control unit 170 Release (23) so that the returnee can exit. (ST18)

If, in step ST 15 above, the facial information encryption code of the emergency gate requester is registered in the server 200, a warning may be generated while maintaining the locked state of the locking device 23. There is no limit to the warning method, and for example, a message stating,'The customer has a history of illegal rides, can no longer use the emergency gate' may be displayed on the display 130, or may be output through a speaker.

If the encryption code of the user's facial information matches the password of the criminal or wanted person stored in the search requester DB 220, the relevant information (time, subway station name, gate number, etc.) can be transmitted to the police office server or the police officer terminal. . (ST19)

In addition, in step ST17, if it is determined that the passenger is an illegal passenger because it does not return within the set time, the first determination unit 150 transmits the user's facial information encryption code to the server 200 and requests registration to the illegal passenger DB 230. do. (ST20)

On the other hand, even though the illegal ride monitoring device 100 is installed as described above, there may be a person who tries to jump over the door 21 of the emergency gate 20 or crawl downward, so it is also necessary to detect this type of illegal ride.

Hereinafter, a method of detecting this type of illegal ride will be described with reference to FIG. 11.

First, a body image and a face image of all people approaching the emergency gate 20 are acquired by using the second camera 110b installed on the emergency gate 20. (ST31)

Subsequently, the encryption code generation unit 120 generates an encryption code from the feature points of the face image. If necessary, an encryption code may be generated from the feature points of the body image. (ST32)

Then, using the posture information obtained from the body image, it is determined whether or not to ride illegally. This determination may be performed by the second determination unit 160 of the illegal ride monitoring apparatus 100 or may be performed by the attitude determination unit 240 of the server 200. (ST33, ST34)

Subsequently, when the second determination unit 160 or the attitude determination unit 240 determines that the posture of the person entering the vehicle corresponds to an illegal ride, a predetermined warning is generated. The warning may be, for example, a voice output stating,'If you take an illegal ride, your face information is automatically stored in the server and you may be disadvantaged in the future.'

When the illegal ride monitoring device 100 generates a warning, the illegal ride monitoring device 100 transmits information such as the face information encryption code, access time, subway station name, and gate number of the illegal passenger to the server 200 at the same time as a warning. 230). (ST35)

In the above, a preferred embodiment of the present invention has been described, but the present invention may be implemented after being modified or modified in various forms in a specific application process.

As an example, since the illegal ride monitoring device 100 shown in FIG. 2 is installed only on the outside of the emergency gate 20, it is inconvenient or impossible for people located inside to use the double-sided monitoring device as shown in FIG. 100a) can also be used. The double-sided monitoring device (100a) includes a first display (130a) and a second display (130b) respectively installed on the outside and inside of the emergency gate (20), the top of the first display (130a) 1 The camera 110a-1 may be installed, and the 1-2 camera 110a-2 may be installed on the top of the second display 130b.

In this case, the first display 130a and the first-first camera 110a-1 may be used to output a message and photograph a face to a person who wants to enter the emergency gate 20 from the outside. In addition, the second display 130b and the 1-2th camera 110a-2 may be used to output a message to a person who intends to come out from the inside of the emergency gate 20 and photograph a face.

In addition, as shown in Fig. 12, by installing the 2-1 camera (110b-1) and the 2-2 camera (110b-2) in opposite directions on the top of the emergency gate 20, respectively, the emergency gate 20 You can also photograph the faces and bodies of people leaving and entering.
