Abstract
Description
The present invention relates to an access authentication device which is connected to an accessing terminal of a visitor by Bluetooth and is provided with authentication information and performs access authentication, wherein an antenna for Bluetooth is separately installed outside and inside, The present invention relates to a Bluetooth access authentication apparatus and a Bluetooth access authentication method capable of preventing an access authentication process from being performed using a Bluetooth connection.
Bluetooth was one of Ericsson's first localized communication standards developed in 1994, and is widely used for voice and data transmission. Bluetooth has several advantages over other wireless methods. Unlike wireless LAN, Bluetooth is not sensitive to walls and obstacles, so data transmission rate is high and it does not have directionality, so it does not need to maintain constant direction like TV remote control. In addition, Bluetooth has excellent security because it transmits data at several frequencies. Therefore, it is almost impossible to find products that are not supported by Bluetooth, because it is almost essential in today's portable electronic products.
Among other things, compatibility is also a major advantage of Bluetooth. Compatibility between supported devices is very good, and connection is possible by simple procedure. The two Bluetooth devices connected to each other are interconnected through a simple pairing process while performing the master and slave functions. The two paired Bluetooth devices can send and receive voice and data.
On the other hand, a door locker provided on a door or the like is controlled by an access control device. The access control device may be provided in a main body and a door lock, or may be provided in the form of a separate access control device or access control device in addition to an additional function. The access control device receives the preset authentication information from the accessing party and performs authentication for the accessing party (i.e., determines whether or not the accessing party is permitted to enter), and opens the accessing door only for the accessing party who has successfully authenticated the accessing party. To this end, the access control device may register and hold the authentication information for the accessing passengers in advance, or may be connected to a separate server for managing the authentication information through a network. In the case of connecting to the server, instead of access control by the access control device, the server may proceed with the authentication procedure. In this case, the access control device provides the authentication information input from the accessing party to the server, and the server performs the authentication process and provides the authentication result to the access control device only.
Here, the authentication methods that can be used for the passenger authentication include (1) a method of inputting a password through a button operation, a method of comparing a password with a registered password by using a magnetic card, RFID (Radio Frequency Identification) ) A method of acquiring an image of a fingerprint, an iris, a vein, a face, etc. from a visitor and extracting the characteristic point and comparing with the registered characteristic point (i.e., registered authentication information) is widely used. For example, an access control apparatus using fingerprint authentication has a fingerprint sensor for reading a fingerprint of a visitor.
On the other hand, as the use of a multifunctional digital terminal (for example, a smart phone) equipped with a Bluetooth interface has been increasing recently, attempts have been made to use Bluetooth for access authentication. When the access control device needs to perform authentication for a plurality of entrants, it must always be in a waiting state for a new entrant. Accordingly, if the access control device is paired with a specific accessing party and performs the authentication process, the access control device should immediately stop pairing with the accessing party and wait for another accessing party.
In this case, the problem is that the Bluetooth interface does not have directionality while allowing connection to a certain distance. The access control device should allow Bluetooth pairing with the passenger whenever the passenger (i.e. the passenger's smartphone) is outside the door. This is because, even after the door has just been opened through authentication, the door can still be outdoors. On the other hand, the user can just enter through the authentication and attempt to pair-pair with the passenger located in the house (i.e., the smartphone of the passenger) again and authenticate the passenger again. This process may proceed without the knowledge of the guest, and as a result, the door may be opened again, even if the user does not want to.
Therefore, in order to use the Bluetooth interface for access authentication, consideration should be given to the non-directional problem of Bluetooth, and it should be possible to confirm whether the passenger is outside the door, outdoors or indoors.

1. Contactless smart digital door lock (Patent No. 10-0836366)
The present invention relates to an authentication method using a smart card connected via Bluetooth or the like However, since the smart card used here is designed to operate only at a very short distance although it is noncontact, since it uses the power provided by the door lock device, the same problems as those presented in the prior art do not occur . The problem presented in the prior art of the present invention occurs when Bluetooth pairing is possible even over a certain distance, such as a mobile phone operating as a master.
It is an object of the present invention to provide a portable terminal which is connected to an accessing terminal owned by an accessing person and is provided with authentication information and performs access authentication while preventing an access authentication process from being performed through an unintended Bluetooth connection with an accessing terminal located indoors And a method thereof.
According to another aspect of the present invention, there is provided an access authentication apparatus that can be connected to an access terminal through Bluetooth, including an external antenna and an internal antenna respectively installed outside and inside the door, And an antenna switching unit for switching one of the external antenna and the internal antenna to the first Bluetooth interface, and includes an authentication processing unit and a malfunction prevention unit.
The authentication processing unit performs access authentication based on the authentication information provided by the access terminal after the connection with the access terminal.
The malfunction prevention unit controls the antenna switching unit to measure the strength of a Bluetooth signal received from the access terminal in a state where the external antenna and the internal antenna are selectively connected to each other, The authentication processing unit may control the access processing unit to perform the access authentication so that the authentication can proceed if the access terminal is outside the door.
According to an embodiment of the present invention, the malfunction prevention unit may request the access terminal to provide a 'data packet for received signal strength measurement' for measuring the strength of the received signal, and transmit the received data packet using the data packet received from the access terminal The intensity of the signal can be measured. Authentication information required for access authentication of the authentication processing unit may be received during a separate access authentication procedure, but may be provided in advance from the access terminal through the data packet for measuring the received signal strength. However, if the strength of the signal received through the external antenna is greater than the signal received through the internal antenna, access authentication is performed using the authentication information.
The malfunction processing unit may display an authentication rejection message on the display unit when the intensity of the signal received through the external antenna is smaller than a signal received through the internal antenna or within a predetermined threshold range. Further, even in this case, when receiving an 'access authentication request' corresponding to the authentication rejection message from the accessing party, the authentication processing unit is controlled to perform the access authentication so that a judgment error based on a change in the unauthorized wireless environment .
In the above operation, the first Bluetooth interface preferably waits for the access terminal operating in one of the master mode and the slave mode while operating in the master mode and the slave mode alternately.
When the access authentication apparatus of the present invention operates in the master mode, the malfunction prevention unit performs the received signal strength measurement operation based on the pairing information signal while receiving the pairing information from the access terminal operating as a slave, unlike the above- can do. As a result of the determination, when the strength of the signal received through the external antenna is larger than the signal received through the internal antenna, the malfunction prevention unit controls the first Bluetooth interface unit to perform the pairing procedure by providing the pairing connection request message So that the pairing and authentication can proceed when the accessing terminal is outside the door.
The access authentication method of the access authentication apparatus according to another embodiment of the present invention is characterized in that the access authentication apparatus includes a first Bluetooth interface which is connected to one of an external antenna and an internal antenna respectively installed outside and outside the door, Completing the Bluetooth pairing; Wherein the malfunction processing unit of the access authentication device measures the strength of the Bluetooth signal received from the access terminal while the external antenna is connected to the first Bluetooth interface after the pairing, Measuring an intensity of a Bluetooth signal received from the access terminal in a state of being connected to the access terminal; And an authentication processing unit of the access authentication device performs access authentication based on the authentication information provided by the access terminal when it is determined that the strength of the signal received via the external antenna is larger than the signal received via the internal antenna .
The access authentication device of the present invention can be connected to an access terminal owned by a user through Bluetooth pairing to perform an access authentication process. Therefore, the accessing party who has registered his / her access terminal in the access authentication device through the registration process in advance does not need to perform any other operation for accessing, and the accessing terminal automatically performs a series of processes such as Bluetooth connection and authentication information provision, . ≪ / RTI >
Furthermore, the access authentication device of the present invention can prevent the occurrence of an event such as a door open by access authentication by an unintended Bluetooth connection operation with an accessing terminal located in a room. To this end, the access authentication device of the present invention uses a method of measuring the intensity of the Bluetooth signal of the terminal by installing an antenna for receiving a Bluetooth signal separately from the outside and the inside of the room, thereby making a judgment error significantly.
Further, the access authentication apparatus of the present invention can operate in either a master mode or a slave mode, by operating the master mode and the slave mode at a predetermined time interval.
On the other hand, in response to an error in determining that the accessing terminal located outdoors is located in the room due to a reception intensity measurement error or the like, which may occur depending on the radio environment in the place where the access authentication apparatus is actually installed, Even if it is judged that it is already located inside or outside the room, it is possible to provide the information to the access terminal so as to allow direct control of the user.
