Method for Controlling An Entrance and Exit Using An Organism Information}

The present invention relates to an access control method using biometric information.

As the society becomes more complex and diversified, various thefts and crimes are increasing, and various offices, banks, and automated teller machines (ATMs) have been installed to prevent them. There are various user authentication devices in the place, the door of the apartment complex, warehouse (safety), etc. in order to identify the identity of the users entering and leaving.

On the other hand, if the ATM is installed as an example, the ATM machine is installed outside the current room after the regular business hours to limit the accessor first, the user must be authenticated by placing a card on the card reader installed outside the door to open the structure It is. In addition, in the case of various offices, access is allowed only through an authentication device such as a card reader.

However, in places where public access is not strictly restricted and places where public access is permitted, various thefts and crimes occurring in such places cannot be prevented or resolved by the above authentication method alone. There is this. That is, even if an unauthorized user possessing a lost card enters the card, the user may be authenticated as a normal user and allowed access. Therefore, even if the normal card is granted access, various theft and Since a crime may occur, only the fact that the normal card is authenticated does not prevent various thefts and crimes.

In addition, in public places that are frequently used by many people, there is a problem that all users can not go through the authentication apparatus as above by obtaining and storing the information necessary for authentication in advance. In other words, they only have a monitoring device (CCTV, etc.).

As described above, the present invention allows input of biometric information with high traceability to a user, and determines whether the biometric information is normal biometric information that can be recognized, thereby controlling access, and storing the input biometric information.

It includes.

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

1 is a configuration diagram of an embodiment of a monitoring system to which the present invention is applied.

As shown in the drawing, a surveillance system to which the present invention is applied includes a biometric information input device 10 for receiving various biometric information (fingerprint information, face information, iris information, etc.) from a user, and a biometric information input device from a biometric information input device. When the information is input, the control device 20 for controlling the opening and closing of the door by only determining whether the biometric information is normal and the opening and closing of the door according to the control of the control device to perform the function of storing the input biometric information It is configured to include a switchgear 30 for.

In this case, the biometric information input device 10 is a device for receiving various biometric information from a user who wants to pass or use a facility where the biometric information input device is provided, and a fingerprint input device for receiving a fingerprint. At least one of the iris input device for receiving iris information and the face shape input device for receiving a face shape is included.

In addition, the opening and closing device 30 generally refers to a device for opening and closing a door, or may be replaced with a device for outputting various alarm messages in a place that does not require the opening and closing of the door.

In addition, the control device 20 determines only whether the biometric information input from the biometric information input device 10 is recognizable normal biometric information, and opens and closes the opening and closing device 30 when the biometric information is normal biometric information. On the other hand, it stores the input biometric information. To this end, the control device 20 is connected to the biometric information input device 10 and the switchgear 30 through a network (or the wired or wireless information input device 10 directly or wirelessly without going through a network). And an interface 21 for accessing the opening and closing device 30, a biometric information recognition unit 23 for determining whether the biometric information transmitted from the biometric information input device is normal biometric information recognizable, and the biometric information. A storage unit 24 for storing the biometric information when the biometric information is recognized by the recognition unit, and an output unit 25 for outputting a variety of information inputted from the biometric information input apparatus so that an administrator can monitor the biometric information; And an input unit 26 for receiving various information and a controller 22 for controlling communication between the interface and each unit.

On the other hand, the monitoring system to which the present invention is applied as shown in the figure may further include a security company system (50). That is, the controller 22 of the control device may transmit an alarm signal to the preset security company system 50 when detecting the abnormality of the input biometric information, wherein the security company system 50 sends a security guard. Got dispatched. In addition, the administrator of the control device may directly send an alarm signal to the security company system 50 through the input device 26.

In addition, as shown in the figure, the monitoring system may further include a biometric information management system 40 operated by a separate company. That is, the control device 20 may store the biometric information input through the biometric information input unit 10 directly in a storage unit 24 that is directly managed by the biometric information input unit 10, but prevents leakage and unauthorized use of biometric information by users. The biometric information may be transmitted to the biometric information management system 40 for management.

In the following description, a method of determining whether the biometric information is normal biometric information recognizable by the biometric information recognition unit 23 of the control device 20 having the above configuration will be described briefly.

First, a method of determining a fingerprint in biometric information will be described.

Fingerprint is one of the most commonly used biometric information. The fingerprint classification method is based on the Henry Fingerprint pattern proposed by Edward Richard Henry of England and Dr. Theoder Roscher is generally classified based on the proposed Hamburg fingerprint pattern classification method.

In other words, the fingerprint is divided on the basis of the ridge flow of the fingerprint, and it can be divided into a vortex, a suppository gate, a palace gate, a wooje gate, a metamorphosis gate, and a damaged gate. It can also be separated by protrusions, intersections, junctions, short ridges, center points, and so on. Therefore, the biometric information recognition unit 23 determines only whether the input biometric information is information that meets the above separation criteria, and determines that the biometric information is normal fingerprint input when the biometric information meets the above separation criteria. It does not go through the process of comparing the pre-stored user fingerprint and the input fingerprint.

On the other hand, even if the input fingerprint meets the above separation criteria, if the quality of the condition is not good by checking the density of the noise component, etc. may not be recognized as a normal fingerprint. In other words, if the fingerprint cannot be read normally, such as when the user intentionally twists the input fingerprint, it may not be recognized as a normal fingerprint.

In addition, even when the input fingerprint meets the separation criteria as described above, by comparing the sensor size with the image acquisition size and the like, if it is determined that the input is intentionally reduced, it may not be recognized as a normal fingerprint input.

That is, when it is determined that the fingerprint information input through the biometric information input device 10 is a normal fingerprint that can be recognized, the biometric information recognition unit 23 transmits the corresponding information to the controller 22. The controller 22 may transmit and store the biometric information to the biometric information management system 40 through the storage unit 24 or a network. On the other hand, if it is determined that the biometric information recognition unit 23 is not a normal fingerprint that can be recognized, the biometric information recognition unit 23 transmits a message indicating that the recognition is impossible, and the control unit 22 is shown in the drawing. Fingerprint input using an output device (LCD monitor, speaker, etc.) provided in the biometric information input device 10, or a general output device (LCD monitor, speaker, etc.) provided together at the position where the biometric information recognition unit is provided. You can also force the user to re-enter the fingerprint by sending a message requesting that the user be reinstated.

Next, a determination method for the face shape in the biological information will be described.

At this time, the biometric information recognition unit 23 determines whether the user's face shape is normal biometric information recognizable by the principle similar to that described in the fingerprint recognition process. That is, the biometric information recognition unit 23 may have a foreign object that cannot distinguish the face, such as a mask, an object other than eyeglass frames, a cloth, or the like on the user's face using a general face shape recognition algorithm, If the user's face shape cannot be normally recognized due to unevenness or various noises, the message as described above is transmitted. When the face shape is recognized as the normal face shape, the controller 22 can store the face shape information. Make sure

Similarly, in the case of iris information in the biological information, the controller 22 inputs the input iris information only in the case of normal iris information that can be recognized.

2 is a flow chart of an embodiment of an access control method using biometric information according to the present invention, particularly in a public place where it is necessary to control access of a user, such as an ATM. The access control method is shown.

That is, the user can transmit his / her biometric information (fingerprint information, face shape information, iris information, etc.) through the biometric information input device 10 installed in the door of the place where the ATM is installed, the door of the office, or the door of the apartment complex. It is entered (202).

In this case, the input biometric information is transmitted to the biometric information recognition unit 23 through an interface of a network and the control device, and the biometric information recognition unit determines whether the biometric information is normal biometric information that can be recognized as described above. It is determined (204).

That is, the biometric information recognizing unit 23 transmits the corresponding information to the control unit 22 when the input biometric information is the recognizable normal biometric information as described above, and the control unit 22 controls the door opening. By transmitting a signal to the opening and closing device 30, the user can enter and exit (206).

At this time, the control unit 22 opens the door (206) and stores the input biometric information in the storage unit 24 (208). Meanwhile, in the storing process, an input date of the biometric information. By storing information on an input time, an input position (serial number assigned to the biometric information input device), and the like, the information can be used later when a problem occurs.

On the other hand, if it is determined that the input biometric information is unrecognizable abnormal biometric information (204), the biometric information recognition unit 23 transmits the corresponding information to the controller 22, and the controller 22 As described above, the biometric information re-input request signal is transmitted to a general output device (LCD monitor, speaker, etc.) installed at the place where the biometric information input device 10 is provided (210).

That is, the user re-enters the biometric information after confirming the re-input request signal as described above (202), and the biometric information recognizing unit 23 performs the determination process 204 as described above.

On the other hand, although not shown in the drawings, if the above-described process is repeated, that is, if the input biometric information is recognized several times as unrecognizable abnormal biometric information, the control unit 22 is irradiated with the security company system 50 By sending a request message or by sending a survey request message to the output unit 25, the administrator of the security company system or the administrator of the control device 20 may be to check the biometric information input device 10 directly.

In addition, the biometric information input process 202 may require other identification tracking input such as a resident registration number, a driver's license number, a credit card, etc. In this case, the control device 20 stores the identification tracking information as described above. The unit 24 or the biometric information management system 40 may be stored together with the biometric information.

In addition, in the process of storing the biometric information 208, the biometric information may be stored in various forms. The reason for storing the biometric information in various ways is that the biometric information is used illegally or illegally. It is to prevent becoming.

First, there may be a method of storing the original image as it is. That is, an image of the input fingerprint information, face shape information, iris information, and the like is stored in the storage unit 24 or the biometric information management system 40 as it is.

Second, there may be a method of compressing and storing the original image. That is, the original image of the input biometric information is compressed and stored in the storage unit 24 or the biometric information management system 40. In this case, the compressed image information may be decompressed and read only by an administrator who has permission to use the control apparatus 10 or the biometric information management system 40.

Third, as a method of encrypting and storing the original image of the inputted biometric information, it is possible to decrypt and read the encrypted image only by an administrator having permission to use the same as the second method.

Fourth, as a method of extracting and storing feature points from the original images of the inputted biometric information, the biometric information can be read using an algorithm related to the feature point extraction only by an administrator with permission, similar to the second and third methods. Can be.

Fifth, a method of dividing the original image of the input biometric information into at least two or more images to be stored through different storage media, this method is filed by the applicant of the present invention (application number: 10-2001-0047576) In the received [biological information division storage method], the concept is similar to the method of dividing and storing the biological information. That is, a method for dividing the input biometric information into a plurality of storage units 24 of the control device 10 and storing the input biometric information into a plurality of storage media of the biometric information management system 40. The biometric information is divided into the storage unit 24 and the biometric information management system 40, and stored in a plurality of biometric information management systems 40 managed by different companies. It may be made in various forms such as a method of dividing and storing each. In this case, the images of the divided biometric information may be combined only with the consent of each manager of the divided and stored media. In this case, by applying techniques such as compression, encryption, feature point extraction, and the like described above, unauthorized or illegal use of the biometric information may be further prevented.

On the other hand, the biometric information stored in each storage medium by the above methods can be automatically deleted when the set retention period has elapsed, thereby preventing its abuse.

Hereinafter will be described the application field of the access control method using the biological information according to the present invention described above.

As described above, the present invention allows the user to input only his / her biometric information to the biometric information input device 10 installed at the entrance of a public place, such as a place where an ATM is installed, an office, an apartment complex, etc., without various user authentication procedures. It is allowed to pass through the door. That is, the control device 20 does not need to be preset and stored with any information for user authentication, and only determines whether the biometric information input through the biometric information input device 10 is recognizable normal biometric information. In the case of information, only the function of passing the user and storing the biometric information is performed.

In other words, the access control method using the biometric information according to the present invention does not determine whether the user is a user who is authorized to access, and controls whether to enter or not, and determines whether only the biometric information has been inputted. Control whether or not.

On the other hand, the present invention, by controlling the access to the above as described above by storing the normal recognized input biometric information in a variety of ways as described above, it is possible to use the stored biometric information when various problems occur.

That is, when various thefts or crimes occur in a place where access is allowed through the biometric information input device 10, the biometric information stored in the storage unit 24 or the biometric information management system 40 is searched. This will allow you to track down suspects of theft or crime.

In this case, as described in the storage process 208, the input date, the input time, and the input position of the biometric information are stored together, and thus may be used for tracking the suspect.

In other words, the present invention as described above is used by many people, but in a space that needs to control and manage the access, by controlling the access control of the user only on the condition of normal input of the biometric information, users more convenient In addition, by managing the biometric information of users entering and leaving, it is possible to detect the suspect by tracking the biometric information in the event of various theft or crime.

Meanwhile, hereinafter, another application field of the access control method using the biometric information according to the present invention in addition to the above method will be described briefly.

First, it can be used to check the patrol time of patrols. That is, since patrols such as buildings pass through various doors and the like by the above-described method, various kinds of information about the patrolrs are stored in the control device 20, and thus, the patrol journal may be substituted.

Second, by using a variety of user monitoring sensors can also supplement the function of the access control method according to the present invention. That is, when the control unit 22 determines that there are two or more users who have passed through the door by various sensors even though there is only one biometric information input through the biometric information input device 10, an unauthorized intruder intrudes. It may be detected that, to send the alarm signal to the security company system 50, or to send the alarm signal to the output unit (25). However, the biometric information is inputted through the output device (LCD monitor, speaker, etc.) provided in the biometric information input device 10 or provided at the position where the biometric information input device 10 is installed before the alarm action is taken. It may also send a message requesting entry.

Third, the access control method according to the present invention can also be applied to the normally open door. That is, in the case of an entrance door in an office such as a bank, the door itself may be kept open, but after entering the biometric information through the biometric information input device 10 as described above, the user may enter the office. You can also do that.

For example, if a user who wants to enter the bank determines that the door is open and tries to enter immediately, the sensor senses the transmission to the control device 20 and the control unit 22 of the control device 20 sends the biometric information. By inputting a message through a monitor or a speaker to enter after inputting, a user may input biometric information and reenter it. That is, in the case of an office such as a bank, if the same method of the present invention is applied, intruders who want to attempt various theft or crime in the bank also cannot enter theft or crime because they have to enter and enter their biometric information.

On the other hand, in case the intruder enters without inputting the biometric information, in addition to outputting the above warning message through the monitor or the speaker, the non-biometric inputter enters the monitor of the guard or the administrator of the office. Information can be printed so that the guard or managers can have a primary guard post. That is, when the security guard or the manager of the bank confirms that there is an intruder as described above, it is ready to issue an alarm to the security company system 50 and re-enter the biometric information according to the warning message of the monitor or speaker. In the case of entry, the alert is not issued, and in spite of the warning message, if the intention to enter into an illegal act is seen, the alert may be immediately transmitted.

Fourth, in the case where the switchgear is provided more than two, if the user enters through the biometric information check in the first switchgear device as described above, after the second switchgear device may enter the user without a separate confirmation procedure.

Fifth, by storing the time to which the access control method using the biometric information according to the present invention as described above in the storage unit 24 of the control device 20, a predetermined time, for example, lunch time, dinner The method may be applied only when the user frequently enters or exits such as time.

Since the present invention does not need to input user information for authentication in advance, there is an excellent effect that it is possible to restrict the entrance and exit in the space and place where the unspecified number of persons difficult to register in advance.

In addition, the present invention has an excellent effect that a variety of facilities can be conveniently used from the user's point of view without having to disclose additional personal information for permission to access.

In addition, the present invention stores the biometric information of the user input at the time of access, there is an excellent effect that the biometric information can be used when a crime occurs. Therefore, those who commit crimes are reluctant to enter and leave the place where the biometric information input device 10 applied to the present invention is installed. Therefore, the present invention has an excellent effect of preventing crime in various public places.

That is, the present invention can be more conveniently used by users by managing a user's access control only under the condition of normal input of biometric information in a space that is used by a large number of people but needs to control and manage the access. On the other hand, by managing the biometric information of users entering and leaving there is an excellent effect that the suspect can be detected by tracking the biometric information in the event of various theft or crime.
