[0001] ACCESS CONTROL MANAGEMENT SYSTEM USING BEACON TECH [0002]

The present invention relates to an access control management system using a beacon, and more particularly, to an access control management system using a beacon, and more particularly, And a beacon that allows the authorized person to access the specified area and allows the accessing person to identify and manage the time or movement within the specific area Access control system.

The company's research institutes and major facilities are equipped with various access control systems to prevent outsiders from accessing them. For example, there is a security check box at the entrance of a specific area, so that a method of verifying the identification of a person who intends to enter the room, and a method of passing through a search block using a previously assigned security card, Has been commercialized.

However, the access control management system according to the related art has a problem in that it is time consuming and also inaccurate because it is necessary to confirm the identity card of the passenger and the identity of the passenger. In addition, since it is a matter of mainly managing whether or not a person entering the room is allowed to enter the room, it may be difficult to confirm whether or not the occupant has escaped to the outside. Further, even in the case of using a security card, the security card must be in contact with the scanner of the search station, and it is vulnerable to duplication of the security card.

On the other hand, in recent years, there has been a growing interest in access management systems using beacons, and access control systems using beacons have been used in some cases. Beacon is a technology that uses Bluetooth 4.0 or higher, and is a new technology that attracts attention because it has a wide communication range, high accuracy, and low power consumption compared to conventional Bluetooth communication. In addition, unlike conventional Bluetooth, there is an advantage that pairing is not required (auto-pairing is supported) and operation can be performed at a relatively low cost. However, since it is difficult to judge accessibility with only the beacon itself, it is vulnerable to hacking because it transmits / receives information by broadcasting (Broadcasting) method, and since it can be replicated on a smartphone which can be used as a beacon scanner and a virtual beacon, It is vulnerable.

FIG. 2 is a view showing a doorway configuration of an access control device using a beacon according to the present invention; FIG.
FIG. 3 is a flowchart illustrating a method for controlling an access using a beacon according to the present invention; FIG.

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

FIG. 1 is a block diagram illustrating a schematic configuration of an access control apparatus using a beacon according to the present invention, and FIG. 2 is a diagram illustrating a configuration of an access port of an access control apparatus using a beacon according to the present invention.

1 and 2, the access control system using a beacon according to the present invention includes a beacon scanner 210, an infrared sensor 220, a random number database 230, an access database 240, A beacon recognition unit 200 configured to include a beacon recognition unit 200; And a beacon terminal 100 including an identification information unit 110, a random number algorithm 120, a counting unit 130, and a transmitting unit 140.

The beacon scanner 210 may be provided at an entrance or exit of a secure area or a security facility where only a specific authorized person can enter and exit. When the beacon terminal 100 is within a predetermined area (reception range), the beacon terminal 100 detects the beacon terminal 100 and receives identification information and security information to be described later from the beacon terminal 100. Beacon is a low-power Bluetooth (BLE) communication technology that can communicate over a range of up to 70 meters, is highly accurate enough to distinguish between 5 and 10 centimeters, and consumes very little power, There is an advantage that it can be connected and used all the time. In addition, there is an advantage that connection is possible without a passive pairing process like the conventional Bluetooth (supporting an auto-pariing function) and is cheap. The beacon is a well-known technique and a detailed description thereof will be omitted. In addition, the beacon terminal 100 described below will be described with an ibeacon as an example. The beacon scanner 210 may be provided at the entrance of the security zone or the like, and may be provided at the entrance and exit of the beacon scanner 210, respectively.

The infrared ray detection unit 220 is provided at an entrance for controlling and controlling entrance and exit to determine whether a person passes through the entrance. The infrared ray detection unit 220 can be provided inside and outside the doorway to determine the direction of entrance and exit. For example, when the infrared sensing unit 220 provided inside the doorway and the infrared sensing unit 220 provided at the exterior are sequentially sensed, it can be determined that the sensing unit 220 exits from the inside to the outside, and the external infrared sensing unit 220 and the internal infrared sensing unit 220 are sequentially sensed, it can be determined that the external infrared sensing unit 220 enters from the outside to the inside. Thus, it is possible to manage the access time and the time spent inside.

If the beacon scanner 210 detects that the beacon terminal 100 is not detected by the infrared sensor 220 in the above-described configuration, a person passing through the current doorway enters or exits the security zone It is not possible to open the door or send an alarm signal to notify the administrator. On the other hand, when the infrared sensor 220 detects a person's access and the beacon scanner 210 detects a signal, the beacon terminal 100 compares the identification information with a security code to be described later, It is judged whether it is legitimate. At this time, the beacon terminal 100 includes a person having the beacon terminal 100, and the following description is the same. A method for determining whether the beacon terminal 100 is authorized for the beacon terminal 100 when the beacon terminal 100 is detected will be described later.

The random number database 130 stores a random number table having the same generation mechanism as the random number received from the beacon terminal 100 and compares the random number table with a random number received from the beacon terminal 100. The access database 240, The personal information of the person allowed to access is stored corresponding to the identification information received from the personal computer 100. The control unit 250 processes signals received from the beacon scanner 210, the infrared ray sensing unit 220 or the beacon terminal 100 and compares the received signals with the databases 230 and 240, And notifies the user of the information. In the following description, the control unit 250 is used to refer to a device having the same or similar function as the server.

The beacon terminal 100 is distributed to a person permitted to enter and leave the security zone, and the beacon terminal 100 is provided with identification information and a security code. In the case of the ibeacon, a prefix (9 bytes) indicating the type of the beacon, a UUID, 16 bytes, a major number (2 bytes), a minor number (2 bytes) Power, 1 byte), which is composed of 31 bytes in total. The sections that can be arbitrarily changed and used by the user in these configurations are the UUID, the major number, and the minor number part, and the identification information and the security code to be described later can be input to these sections. TEX POWER stores the battery remaining amount information of the beacon.

The identification information may be composed of various kinds of unique numbers that can identify the person allowed to enter the security zone. For example, it may be composed of a combination of a number or a letter meaning a company ID, a part number indicating a department, a name (employee number, serial number), etc. , And in some cases, information for a temporary visitor. Thus, when the identification information is received by the beacon scanner 210, the information corresponding to the identification information can be compared with the information of the accessing person database 240 to determine whether the person is permitted to access.

The security code determines whether the beacon terminal 100 which transmits the identification information is registered in advance and whether it is a terminal operated by duplication or the like. In a preferred embodiment of the present invention, the security code is transmitted to the beacon terminal 100 The random number algorithm 120 may be provided to compare the random number generated by the random number algorithm 120 with a random number table stored in the random number database 230 of the controller 250 to determine whether or not they match.

The beacon is not always kept active, but most of the time is kept in a sleep mode and a very short time is active, allowing the signal to be emitted only in the active state. Therefore, bidirectional communication in which the beacon scanner 210 requests the beacon terminal 100 for a random number of a specific order is difficult, so that the currently received random number is compared with any random number stored in the random number database 230 of the controller 250 There is a problem that it is difficult to judge whether or not it becomes a target.

To this end, the access control management system using the beacon according to the present invention further includes a counting unit 130 in the beacon terminal 100 to measure the order in which random numbers are generated in the random number algorithm 120, The beacon scanner 210 receives the random number generated by the beacon terminal 100 and the random number generated by the beacon terminal 100 and outputs the generated random number to the random number database 230 of the controller 250. [ Number table stored in the random number table. As described above, the beacon terminal 100 generates and transmits a random number when the beacon terminal 100 is in an active state. The activation state can be arbitrarily set by a user or an administrator. Since the user or the administrator can arbitrarily determine the timing and the period at which the random number is generated, the counting unit 130 may measure only the random number generation sequence. For example, when the user or the administrator sets the activation period of the beacon terminal 100 to be several seconds or less, the period in which the random number is generated is set to be a random number every once every activation period, In this case, the counting unit 130 may ignore the activation period and count only the number of times the random number is generated (sequence number), and transmit the counted number.

On the other hand, when a plurality of beacon terminals 100 are operated, since each beacon terminal 100 has different registration times, the timing and the sequence of generating random numbers are different. Therefore, the access control management system using the beacon according to the present invention is configured to synchronize the generation order of the random numbers generated in each beacon terminal 100 by synchronizing with the time when the beacon terminal 100 is registered in the controller 250 do. For example, when the beacon terminal 100 and the beacon terminal 100 are registered at different times, A and B are different depending on the time of activation according to the registration time, the number of times the random number is generated, do. Accordingly, when the beacon terminal 100 counts the number of occurrences of the random number and the random number generated in each of the beacon terminals 100 on the basis of the registration of the beacon terminal 100, the control unit 250 controls the beacon terminal 100 corresponding to the received identification information, It is judged whether or not the random number table matches the random number corresponding to the order of generation in the random number table made based on the registration time of the mobile terminal 100. Thus, even if the random number received from each beacon terminal 100 is different from the random number generated by the beacon terminal 100, the controller 250 compares the received random numbers with the random number table corresponding to the random number generation sequence of each beacon terminal 100, 100) is a registered terminal operating normally.

Various known methods can be used as a method of registering the beacon terminal 100 in the controller 250 and synchronizing the same. For example, if the beacon terminal 100 and the control unit 250 have an RFID function and register the beacon terminal 100 in the control unit 250 using the RFID, the counting unit 130 of the beacon terminal 100, The control unit 250 counts a random number generated after the reset of the beacon terminal 100 and transmits the random number to the beacon terminal 100 based on the registered time of the beacon terminal 100, Table, and compare the random number received from the beacon terminal 100 with the random number table corresponding to the generation order. Various known methods can be applied as a method of registering the beacon terminal 100 in the control unit 250. [

FIG. 3 is a flowchart illustrating a method of access control using a beacon according to the present invention.

Referring to FIG. 3, the access control method using a beacon according to the present invention includes receiving and sensing a signal transmitted from the beacon terminal 100 (S140); A step (S160) of judging whether the input / output is performed through the infrared detection unit 220; (S170, S180) for checking whether the access code is authorized by checking the identification information and the security code received from the accessing beacon terminal 100.

The beacon terminal 100 activates the beacon scanner 210 in a constant cycle at all times to generate a random number S110 and the counting unit 130 measures the sequence of generating the random number S120, (S130). When the beacon terminal 100 that continuously performs this operation enters the receiving area of the beacon scanner 210, the beacon scanner 210 receives the identification information and the security code at that time (S140). When a person having the beacon terminal 100 enters the entrance, the infrared ray detector 220 detects the beacon terminal 100 and transmits the identification information and the security code of the beacon terminal 100 to the random number table stored in the controller 250, (S170, S180) whether the user is authorized to enter or leave the room. That is, the identification information is compared with the accessing person database 240 to inquire whether the person is permitted to access and the time when the corresponding beacon terminal 100 is registered. If it is determined that the user is permitted to access, the security code is compared with the random number database 230 to check the security of the beacon terminal 100. The security code includes a random number generated from a random number algorithm 120 built in the beacon terminal 100 and a random number generated in the random number database 230 of the control unit 250 as described above, And compares the generation order of the random number with the time when the beacon terminal 100 is registered and synchronized with the controller 250 and compares the counted number. As described above, the beacon terminal 100 generates the random number once every time the beacon terminal 100 is activated or once every several activation cycles, and the counting unit 130 generates the random number sequence Based on the time when the beacon terminal 100 is registered. The step of comparing the identification information and the security information received from the beacon terminal 100 with the access database 240 and the random number database 130 may be performed when a visitor passes through the infrared sensor 220, May be performed before the passer passes through the infrared ray sensing unit 220.

If both the identification information and the security code received from the beacon terminal 100 are determined to be normal through the above process, the beacon terminal 100 passes the person having the beacon terminal 100 as it is, If it is judged that there is something wrong with the identification information and the security code, the administrator can be informed through the door or the alarm sound.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be defined by the appended claims and equivalents thereof.
