However, in the case of such a key method, there is a problem in that a specialized company must be separately called to open the front door in case of loss, and there is a problem that the front door can be opened with a tool other than the key, making it vulnerable to crime.

The current electronic door lock was developed to complement this. 1 is a simplified representation of a conventional electronic door lock.

In the conventional electronic door lock (1), a plurality of number buttons (2) are described on the surface of the door lock (1), and a preset number arrangement and the user presses the number button (2) with the button (2) with a finger (3). It is designed in such a way that the lock is released when the number array entered by pressing becomes the same.

However, such a conventional electronic door lock has the following problems. First, when repeated use is made, the number buttons corresponding to the preset number array are worn out or a fingerprint is formed, so that another person can give a hint that the corresponding number button corresponds to the number array. There was a problem to be exposed.

In addition, when pressing the number button, the finger moves with a relatively large motion, so that a criminal or the like watching from a distance can easily recognize the number arrangement. Due to this, security is weakened, and in particular, women living alone are the main targets, causing various social problems.

The input authentication information is transmitted to the locking device 200. The locking device 200 may receive such authentication information, verify the authentication information according to a preset method, and release the locking device when the verification is successful. A detailed description of this will be described later.

When pressing a number button in a conventional electronic door lock, since the finger moves with a relatively large motion, there is a security problem that occurs because a criminal watching from a distance can easily recognize the number arrangement. However, according to the present invention, The conventional problem can be solved because the lock is unlocked only by recognizing the marker through augmented reality without a separate large operation and inputting authentication information on the application.

Referring to FIG. 4, the configuration of the terminal unit 100 and the locking device 200 according to the present invention will be described in detail.

The terminal unit 100 and the locking device 200 may further include components necessary for service implementation in addition to the illustrated components.

The terminal authentication management unit 120 may register, delete, and change user authentication information. For example, the terminal authentication management unit 120 may register authentication information while being connected to the server unit 300 through an application. For this reason, it is possible to increase security by inputting user's unique information.

The form of the authentication information is various, for example, preferably a fingerprint, a password, a pattern, and the like. However, it is not necessarily limited to this example.

The marker unit 130 supports a function of registering or changing a marker capable of recognizing the locking device 200 in the terminal unit 100 in augmented reality. A marker to be used by the user can be previously registered and matched, thereby improving security.

The augmented reality unit 140 displays the current image and scans a marker from the image. It may include a camera for photographing a marker.

Due to the configuration of the terminal unit 100 as described above, a user can implement augmented reality through an application and recognize a pre-registered marker on the augmented reality. Thereafter, the terminal unit 100 encrypts the user authentication information and transmits it to the locking device unit 200.

The lock authentication processing unit 230 serves to compare and verify the user authentication information received from the terminal unit 100. For example, the lock authentication processing unit 230 may receive the encrypted authentication data from the terminal unit 100 and decrypt the authentication data according to a predefined algorithm or decryption method to obtain authentication information and anchor values necessary for authentication. . The lock authentication processing unit 230 may transmit the verification result to the terminal unit 100 after verification is completed.

The lock security unit 250 is a module that encrypts user authentication information. For example, the lock security unit 250 may be a security module separated by hardware on the terminal unit 100. The lock security unit 250 may encrypt authentication information requiring encryption processing for security purposes according to a predefined method, and transmit it to the lock authentication management unit 220 for storage. In addition, the lock security unit 250 may interwork with the lock authentication processing unit 230 to support performing encryption and decryption operations when verifying authentication information.

5 is a flowchart illustrating an operation of a smart door lock unit using augmented reality according to the present invention. Hereinafter, with reference to FIG. 5, an operation mechanism of a smart door lock unit using augmented reality according to the present invention will be described.

In this case, the authentication information may be authentication information directly input through the terminal authentication management unit 120 or may be an initial application value. At this time, the user inputs authentication information (S103).

When authentication information is input to the terminal unit 100, authentication data is generated (S104). The authentication data may generate authentication data by encrypting an authentication information value input by a user and generating a value for additional authentication.

Thereafter, the terminal unit 100 transmits the authentication data, and the locking device unit 200 verifies the authentication data based on the received authentication data (S105). At this time, the lock authentication processing unit 230 compares the authentication data with the authentication data. When the data verification is completed and it is determined as success, the locking device 200 releases the lock (S106).
