The access control system is a kind of security device installed to identify the identity of the passengers and to allow access or to prevent external intrusion, and is widely used in enterprises as well as in each family.

Various configurations for releasing the locking device in such access management systems have been described. For example, there is an access management system that uses biometric information in recent years including a key, a password, a security card, and the like. In addition, an access control system for multiple security is also developed by composing the above-described configurations in a complex manner.

One of the systems for access control according to a complex configuration is disclosed in Patent Publication No. 10-2010-0010465, which describes an access control apparatus and method through comparison of personal identification characters and biometric information.

The above-described technology has a first opening and closing part for opening and closing a door, a second opening and closing part for opening and closing the door, a database, a personal identification character input part, a biometric information acquiring part, personal identification characters inputted through the personal identification character input part, When the coincidence accuracy between the biometric identification information and the user biometric identification information obtained from the user is equal to or greater than the reference accuracy, the second opening / And a control unit for releasing the opening and closing unit.

The above-described conventional techniques have an advantage that they can be advantageously used in a group of relatively small number of passers-by. In other words, security can be improved because access can be managed through individual identification characters or smart cards and biometric information given to each individual.

However, there is a problem in that a large number of people and time are spent in administering them, since frequent passengers are frequently visited or a group of people used by a large number of people use individual identification letters or distribute smart cards.

In addition, in the case of a large-scale business, an area requiring deep security is set up. The above techniques are applied to such a large-scale business, and it is difficult to set up security in depth.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents It should be understood that water and variations may be present.

Before describing the present invention with reference to the accompanying drawings, it should be noted that the present invention is not described or specifically described with respect to a known configuration that can be easily added by a person skilled in the art, Let the sound be revealed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and a method for managing entrants as a group using a PIN (Personal Identification Number) and biometrics, and more particularly, And more particularly, to a system and method capable of managing a passenger by recognizing a passenger in the group specified through the biometric unit.

Accordingly, the access management system using the pin and biometrics according to the present invention includes the management server 100 and the access management gate 200.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of an access management system using a pin and biometrics according to the present invention, and FIG. 2 is a schematic internal configuration diagram of an access management system using a pin and biometrics according to the present invention.

The management server 100 controls the access gates 200, 201, ..., 20n and provides the access information and the group information corresponding to the pins to the access gates 200, respectively. Wherein a group corresponding to the pin is set and a biometric information of the passengers and the passengers for each group is stored and managed; .

The biometric information registration terminal 150 shown in FIG. 1 recognizes and registers biometric information of a passenger, receives biometric information and personal information (personal information) of the passenger and transmits the biometric information to the management server 100, A biometric information recognizing scanner for acquiring, an input module for inputting personal information, a display module for displaying the recognized biometric information and the inputted information, and the like. And may further include a camera for registering a face of a visitor. Here, the image input through the camera can be utilized as a face image among elements constituting the body information.

Also, the information constituting the database can be stored and managed by receiving information directly from a vendor requesting access from the outside. That is, a company having a biometric information registration terminal can be provided by registering a passenger directly.

FIG. 3 is a diagram schematically showing a database structure of a management server in an access management system using a pin and biometrics according to the present invention, in which groups corresponding to pins and accessor information assigned to each group are stored and managed.

At this time, the user information is stored including personal information such as the company of the user, department, position, name, age, sex, and the body information. Here, the personal information can be defined and stored and managed as an ID (Identification).

The body information includes at least one of a face image, a fingerprint, an iris, and a hand blood vessel, and is stored in advance through a recognition device or the like capable of acquiring each body information.

A plurality of pieces of body information may be registered in the process of registering body information, so that there may arise a problem that the same person can enter and enter a plurality of pieces of body information in response to one piece of personal information.

For example, the first person can recognize the fingerprint corresponding to the first person's information and enter the biometric information, recognize the hand blood vessel corresponding to the second person's personal information, and input the biometric information to be registered . In this case, the first passenger recognizes the fingerprint, acquires the authentication of the first passenger and enters and exits, and recognizes the hand blood vessel, thereby acquiring the authentication of the second passenger and entering and exiting the passenger.

In order to solve this problem, it is necessary to induce registration of all of the biometric information recognizable by the biometric recognition unit 230 installed in the entrance control gate 200 and to compare the registered biometric information so that a plurality of passengers Lt; / RTI >

When the biometric information recognizable by the biometric recognizing unit 230 provided in the access management gate 200 is composed of a fingerprint and a hand-held blood vessel, the management server 100 converts the fingerprint and the hand blood vessel of the accessing person into biometric information . Next, the registered biometric information is compared with the biometric information stored in the database one by one to verify whether there are two or more biometric information matched with a predetermined matching rate or more, and if there are different pieces of biometric information in the matched biometric information, Lt; / RTI >

Accordingly, it is possible to prevent unauthorized access (proxy attendance) by blocking registration of a plurality of personal information corresponding to body information through such a verification process, so that there is an advantage that the time and attendance management can be performed more thoroughly. In addition, it can prevent unfair labor expenses by blocking illegal work for non-users.

The thus configured database further includes an access gate for access to the group and is stored and managed. This will be described with reference to FIG. 4 attached hereto.

4 is a view showing an embodiment of setting a restricted access area in the access management system using the pin and biometrics according to the present invention. This will be described in connection with FIG. 3 of the accompanying drawings.

Group 1 is set to access gates 1, 2, and 3, and group 2 is set to access gates 1 and 2.

Group 1 can then enter Zone 1 through the gate (see FIG. 4) 1 and enter and exit Gates 2 and 3, thereby entering and leaving Zone 2 and 3.

Likewise, group 3 is in a state capable of accessing zones 1, 4 and 5 via gates 1, 4 and 5.

Therefore, a person belonging to group 1 can not enter zones 4, 5 and 6, and a person belonging to group 2 can not enter zones 3, 4, 5 and 6. However, a person belonging to group m is authorized to access all areas.

This configuration is advantageous for setting the access permitted zone for the group unit since the access zone set in the group unit can restrict the access zone.

In addition, when the company is permitted to visit the related persons of the external organization, it is advantageous to set up a separate group and to set an access restricted zone by setting an allowable zone in which the entrance of the relevant institution can enter.

For example, if the interior construction is requested to an outside organization in Zone 2, if the biometric information and personal information of the entrance / exit passenger are stored in Group 2, only Zone 2 can be accessed through Zone 1, Setting can be easily performed.

Also, even if the number of passengers who can access only Zone 3 is limited, if a new group is created and gates capable of entering into the created group are designated as 1 and 3, the other zones can not enter and exit, There is an effect that can be.

In order to facilitate this, the management server 100 may be configured to provide information of the database 110 to the access control gate 200 only to access control gates which can be accessed.

For example, when information on the group 1 is provided only to the access gates 1, 2 and 3, and information on the group 2 is provided only to the access gates 1 and 2, the access gates 1 and 2 are group 1 And the group 2, and the entrance control gate 3 only has information on the group 1. Therefore, each access gate has only the information of the group to which the access is allowed, so that it is easy to manage the access.

Under different design conditions, the management server 100 transmits a sink signal to the access gate 200 at regular intervals, and determines whether the access gate 200 is operating normally through the received sink signal.

At this time, the access management gate 200, which normally does not respond to the transmitted sync signal or does not respond, can be configured to display an error.

Therefore, it is possible to check the error of the access gate at the remote place, and it is possible to respond quickly.

In addition, the management server 100 may be configured to control the power application to each access control gate or to control the operation of the access control gate.

That is, by controlling whether or not the access gate is operated through the management server 100, it is possible to control entrance / exit of a passenger or to open the emergency gate to evacuate.

The access management gate 200 is a device for opening and closing a gate provided at an entrance and gate and includes a gate 210, a pin input unit 220, a biometric unit 230, a control unit 240, and a gate database 250 do.

The gate 210 performs switching according to a control signal, and may include a gate in the form of a door including a turn-style gate, a full-gate gate, and a bar gate.

Turnstile gates, also called speed gates, are constructed with three bars installed at a constant angle and capable of rotating at a constant angle according to control signals.

Although the full height gate and the bar gate are not separately shown in the drawing, the full height gate is formed in the vertical direction to intercept the entire upper and lower portions of the entrance and exit. In addition, the bar gate is a gate which is rotated in accordance with a control signal in a bar installed in a doorway.

The gate 210 may be a completely closed door type or a simple door-and-door type, depending on the field condition or security level.

The pin input unit 220 is for receiving a pin assigned to a group by a user, and may be constituted by a button-type keypad, a touch-type touchpad, or the like. Also, a display is provided in which a corresponding number is displayed by pressing a button or touching.

Different passengers are assigned to the passengers in each group, and the passengers belonging to the passengers enter the pins in the pin input unit 220 to recognize the pins.

The biometrics unit 230 is for acquiring biometrics information from a visitor, and the biometrics information may be a biometrics information of a person such as a face image, a fingerprint, an iris, and a hand blood vessel.

Depending on the design conditions, a plurality of biometric sections may be configured to recognize two or more biometric information.

The control unit 240 compares the stored biometric information of the passenger corresponding to the input pin with the biometric information recognized through the biometric unit and transmits the control signal to the gate 210. [

That is, one pin corresponds to one group, and each group stores a plurality of entrance information. Here, the entrance information includes the biometric information of the visitor.

Therefore, if a pin is input to the pin input unit 220, it is determined whether the input pin is a valid pin, and if it is determined that the input pin is a valid pin, the access point information of the group corresponding to the input pin is detected. Next, the biometrics information input through the biometrics unit 230 is acquired, and compared with the biometrics information of each of the users of the detected group, it is confirmed whether or not there is a person matching the matching rate or more.

As a result of checking, if there is a detected person with a matching rate or more, a control signal for opening is transmitted to the gate 210.

And a display device and a sound device that are operated under the control of the control unit 240 according to design conditions.

At this time, the display apparatus and the audio apparatus are operated under the control of the control unit 240 and perform guidance for inputting pins and biometric information.

For example, it displays the validity of the input pin, outputs a voice, and sequentially outputs guidance for acquiring biometric information. Also, if the inputted pin or biometric information is not valid, it is guided.

According to another design condition, when the controller 240 determines that the pin or the biometric information is not valid for a predetermined number of times or more, the controller 240 determines that an ineffective accessor is attempting access, generates an alarm, Information. ≪ / RTI >

The gate database 250 is information stored and managed from the management server 100.

At this time, the gate database 250 may be configured to be stored and managed in synchronization with the information provided by the management server 100. [

That is, the information stored in the management server 100 may be transmitted to and stored in the gate database at predetermined intervals, or when the information of the user is corrected or deleted in the management server 100, .

Also, the information stored in the gate database 250 includes an access control gate for the group. That is, each group is set with an access gate.

As a result, the passengers of the group in which the accessible gate is set can enter and exit the corresponding gate, but the group which can not enter and leave the gate can not access through the gate, There are advantages.

In this way, the access management gate 200 is set as a group corresponding to the pin, and a plurality of accessing person information is stored and managed in the group, so that the accessing person is allowed to enter and exit by inputting pins and biometric information sequentially.

Therefore, when the number of passengers is large, the range is narrowed to the group according to the input pin, and it is easy to manage the passengers because the entrance / exit of the passengers is determined through the biometric information of the passengers recognized within the limited range.

In addition, since the stored biometric information to be compared with the recognized biometric information is also reduced to the range of the group, the time for judging the validity is shortened, and the passenger has an advantage of being able to recognize whether or not the access is approved according to the access.

For example, when managing access to a total of 10,000 persons, when one group is configured to be grouped and managed in units of 10 to 1,000 persons, it is possible to manage 10,000 stored biometric information and recognized biometric information for recognized biometric information It is possible to obtain a more efficient and quick access authorization by collating the stored biometric information and the recognized biometric information in a group limited to 10 to 1,000 persons rather than the verification.

Next, an access control method according to the above configuration will be described.

5 is a flowchart illustrating an access management method using a pin and biometrics according to the present invention.

In the present invention, a plurality of passengers are grouped in correspondence with pins, and access control methods for passengers include a PIN recognition step (S10), a biometric information detection step (S20), a biometric information recognition step (S30) (S40), a first matching rate checking step (S50), an unlocking step (S60), an access information storing step (S70), and a biometric information updating step (S80).

(1) Pin recognition step (S10)

The pin recognizing step S10 is a step of recognizing a pin input from a passenger and recognizing a pin input by the passenger using the pin input unit 220. [ At this time, since the pins correspond to the groups, the input pins define a specific group.

At this time, a corresponding access management gate of the group is set, and the accessor belonging to the group can be configured to be allowed to access only the corresponding access gate.

Since the group is stored and managed in association with one pin, when the input pin is valid, only the passer's biometric information of the group corresponding to the pin is detected and compared with the recognized biometric information.

Therefore, when the input pin is not a pin stored in the access management gate 200, the input pin is displayed as invalid or outputted as a voice to restrict access.

(2) Biometric information detection step (S20)

The biometric information detection step (S20) is a step of detecting biometric information on a passenger of a group corresponding to the pin recognized in the pin recognition step (S10), and loads biometric information on all the passengers of the group.

(3) Biometric information recognition step (S30)

The biometric information recognition step S30 is a step of acquiring biometric information from a visitor. When the user enters biometric information using the biometric information 230, the user acquires the input biometric information.

At this time, the biometric information may be at least one of face image, fingerprint, iris, and hand vein.

(4) Biometric information comparison step (S40)

The biometric information comparison step S40 is a step of comparing the biometric information detected in the biometric information detection step S20 with the biometric information recognized in the biometric information recognition step S30, The step of comparing the biometric information and the recognized biometric information is one step.

(5) First matching rate confirmation step (S50)

The first matching rate checking step S50 is a step of checking the biometric information of the first matching rate or more as a result of the comparison of the biometric information comparing step S40.

That is, the first matching rate checking step S50 is a step of comparing the biometric information stored in the biometric information detecting step S20 with the recognized biometric information to find whether there is biometric information matching the first matching rate or more .

(6) Unlocking step (S60)

The unlocking step S60 is a step of unlocking the access management gate 200 when there is biometric information of a first matching rate or more as a result of the first matching rate checking step S50.

That is, if there is biometric information matching the first matching rate or more, the access management gate determines that the passenger corresponding to the biometric information has input biometric information, and releases the lock of the gate 210. [

If there is no biometric information in excess of the set first matching rate, it is determined that the recognized biometric information is invalid and the state of the gate 210 is maintained (state holding step S90).

(7) Access information storage step (S70)

The access information storage step S70 is a step of storing access information of the accessing person when the access control gate 200 is unlocked.

Herein, the access information may be configured to include the personal information of the corresponding person and the access time, and the personal information may be defined and stored again as an ID.

The stored access information can be used for the attendance management and labor management of the corresponding person.

(8) Biometric information update step (S80)

The biometric information update step S80 is a step of updating the stored biometric information with the recognized biometric information when the recognized biometric information is matched with a predetermined second matching rate or more, as shown in FIG.

FIG. 6 is a flowchart of a process for updating biometric information in a PIN and an access control method using biometrics according to the present invention.

According to the accompanying drawings, the biometric information update step S80 includes a second matching rate confirmation step S81, a stored biometric information deletion step S82, and a recognized biometric information storage step S83.

The second matching rate checking step S81 is a step for confirming whether the recognized biometric information is equal to or higher than a second matching rate set.

Biometric information can be gradually changed according to external environment and physical changes. Namely, face images, fingerprints, irises and hand veins, which are biometric information, are changed according to the seasonal environment such as external temperature, weather, temperature, and aging of the body.

However, the stored biometric information used as a comparison object is biometric information of a previous time and may be changed or changed with time, so that there is a certain error in the stored biometric information of the comparison object and the physical information of the current time to access. Such an error may become larger as time elapses.

That is, in order to solve this problem, the present invention is configured to update the recognized biometric information according to the second matching rate set to the new biometric information recognized at the current time.

The stored biometric information deletion step S82 is a step of deleting the biometric information of the stored passenger in the case of the second matching rate or more.

The recognized biometric information storage step S83 is a step of storing the recognized biometric information, that is, the recognized biometric information at the time of access.

According to this configuration, if the first matching rate is higher than the first matching rate, the gate 210 is unlocked. If the second matching rate is higher than the second matching rate, the gate 210 is unlocked and the biometric information is updated to the recognized biometric information.

For example, when the first matching rate, which is a condition for opening the access control gate, is set to 90% or more and the second matching rate, which is an updating condition, is set to 95% or more, the biometric information matching rate of the current accessing person is 96 %, It is configured to authenticate the passenger and open the gate, and to update (update) the newly recognized biometric information with the biometric information of the passenger.

As a result, the biometric information of the passenger has the advantage of reducing the error by corresponding to the changed back vein as the biometric information is updated.

(9) Biometric information verification step (S100)

The biometric information verification step S100 is a step of determining whether there is different personal information about biometric information that is compared with previously stored biometric information when new biometric information is registered or updated.

That is, by comparing the registered biometric information with the stored biometric information, the same biometric information can be configured so that a plurality of entrances can not be duplicated.

In other words, the registered biometric information is compared with the biometric information stored in the database one by one to verify whether or not two or more biometric information matched with a predetermined matching rate or more exists, and if there is different biometric information in the matched biometric information, Lt; / RTI >

Herein, the biometric information verification step (S100) may be configured so that it can be performed at any time when new biometric information is input, and is preferably configured so as not to be influenced by a sequential flow.

According to the present invention, the entrance and exit management system using pins and biometrics is configured such that a plurality of passengers are set as a group with one pin, thereby facilitating pin management and managing the passengers in the group, and the accessible zone for the group can be separately set , It is possible to set a zone which can be accessed by a group unit and an impossible zone.

In addition, the newly registered biometric information is advantageous in that it can prevent illegal access (substitute attendance) by blocking the registration of two or more pieces of biometric information in the same biometric information through a verification process of comparing the newly registered biometric information with previously stored biometric information.

1 to 6 describe only the main points of the present invention. As far as various designs can be made within the technical scope thereof, the present invention is not limited to the configurations and functions of Figs. 1 to 6 It is self-evident that it is not limited.
