Description

[0001] The present invention relates to a door lock control method using a smart phone,

The present invention relates to a door lock apparatus, and more particularly, to a door lock apparatus which provides an improved security function by allowing a door lock apparatus to transmit a password for opening a door lock to a smart phone when a phone number input to the door lock apparatus is normally authenticated .

Conventionally, although a key is used to open and close a door such as a front door or a door, inconvenience caused by the loss of the key and the necessity of having a key have been encountered.

Recently, a digital door lock device, which is one of door systems, is widely used. Such a digital door lock device is a button-type door opening / closing control system in which a user performs an authentication procedure by using a keypad or a touch-type input method to perform a password process and opens and closes the door. However, since the digital padlock is also exposed to the outside of the door, there is always a security problem due to the leakage of the password. For example, when a keypad is operated, not only a person can see the operation number but also recently a case where a camera is installed near a door to find out a password is often occurring. In addition to this, you can find out the keypad status frequently used for password operation, so that you can get the password only after a short period of time. This is because the password is always fixed to a predetermined number of digits.

Of course, the door opening / closing method using a contact type smart card or a contactless type smart card is applied as a solution for this problem, but since it also needs to have a smart card, There is an inconvenient problem.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a door lock apparatus according to a preferred embodiment of the present invention; FIG.
2 is a flowchart illustrating a method of controlling a door lock apparatus according to a preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a door lock control method and a door lock device using a smart phone according to the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is an overall configuration diagram showing a door lock apparatus of the present invention. FIG. As shown in the figure, the door lock apparatus 100 includes a set of an outer case 110 and an inner case 120, which are disposed on the outdoor side and the indoor side, respectively, with a door therebetween.

The external case 110 is provided with a keypad 111 for inputting a telephone number and a password. The keypad 111 is configured to input a general button, which can be configured by a touch button method. The external case 110 is provided with a call button 112 for requesting a visitor to open the door, a camera 113 for photographing a visitor, a microphone 114 for receiving a voice data signal, a speaker 115 for outputting a voice data signal ) And the like.

A telephone number storage unit 121 is formed in the inner case 120. This is the telephone number of the smartphone 1 held by the visitor who can open the door. That is, setting a visitor for entering the door in advance. When a specific button of the keypad 111 is inputted, the telephone number input state is entered and the number key of the keypad 111 is input. The telephone number is stored in the telephone number storage unit 121 when a specific button is inputted again after inputting the telephone number. Of course you can also store your username along with your phone number.

The display unit 122 may be configured in the inner case 120 to display the stored phone numbers. The display unit 122 allows the phone number and name stored in the phone number storage unit 121 to be confirmed.

The inner case 120 includes a one-time password generating unit 123. [ The password generating unit 123 generates a one-time password only when the primary authentication based on the telephone number input is normally completed, and is a password for opening the door. The password generating unit 123 randomly generates a password, and randomly generates a two-digit password, a three-digit password, a four-digit password, and a password of five or more digits without having a fixed number of digits.

And a communication unit 124 for transmitting the generated password to the smartphone 1. The communication unit 124 performs real-time transmission to the smartphone 1 through a series of communication networks. The communication unit 124 can also be configured in the external case 110.

The control unit 125 controls the entire operation of the door lock apparatus 100 in the inner case 120. Particularly, the control unit 125 has a function of authenticating whether the telephone number inputted through the keypad 111 is a telephone number stored in the telephone number storage unit 121, and a function of authenticating the password inputted to the keypad 111 Thereby opening the door. The control unit 125 may store the one-time password generated by the password generating unit 123 in accordance with the telephone number storage and deletion according to the operation of the keypad 111, the display of the stored telephone number, To the smartphone 1 via the Internet, and all the operations for causing a series of procedures for door opening to be performed even when an unregistered telephone number is input, as described below.

Next, the operation of the door lock device is explained using a smart phone. This will be described separately in the case where the telephone number is registered when the keypad is operated and the case in which the telephone number is not registered.

If the phone number is registered

This may be a case where the telephone number of the visitor is stored in the telephone number storage unit 121 in advance. In the state where the telephone number is registered as described above, the visitor operates his / her keypad 111 provided in the outer case 110 to enter his / her telephone number (s100).

Then, the control unit 125 determines whether the inputted telephone number is stored in the telephone number storage unit 121 (s102). If it is determined that the telephone number is registered (Yes in step 102), the control unit 125 accesses the password generating unit 123 to generate a one-time password (s104). The password may be two or more digits, and the digits will be generated differently each time a password is generated. Of course, this is an example only, and it is possible to generate a password having the same number of digits for each unit of time or number of generated numbers, and to generate a password having a different number of digits when a predetermined time has elapsed or exceeds the number. The generated one-time password is transmitted to the smartphone 1 through the communication unit 124 (s106).

The visitor confirms the password transmitted to his / her smartphone 1, and inputs the password by pressing the keypad 111 of the external case 110 (s108).

The control unit 125 determines whether the entered password is valid. This may be done by comparing the entered password with the one-time password generated by the password generating unit 123. As a result, if the password is valid, the door is opened (S110). On the other hand, if the password is not properly authenticated, the door is kept closed. Of course, in this case, since the password is normally checked but the keypad 111 can be erroneously operated, the password can be inputted two or three times, and if the password is not normally authenticated, .

As described above, the present invention can further improve the security because the first authentication according to the input of the telephone number and the second authentication according to the input of the password are performed. Furthermore, since the one-time password is provided to the registered visitor only when the registered telephone number is input, the password generating unit 123 can generate a password leak that can be generated by always pressing a certain password, It can be effectively prevented.

If the phone number is unregistered

In some cases, a visitor who is not registered in the phone number storage unit 121 may request door opening.

When the visitor enters his / her telephone number (s100), the control unit 125 accesses the telephone number storage unit 121 to determine whether the telephone number is registered (s102).

As a result, if the currently input telephone number is an unregistered telephone number that is not stored in the telephone number storage unit 121 (that is, NO in step 102), the control unit 125 drives the camera 113 to photograph the visitor (S112). Of course, in this case, it is preferable that the controller 125 outputs the guidance message such as " Capture Your Face for Identification " So, if you do not shoot, you can stop the further process.

On the other hand, if the photographing is permitted by the visitor, the control unit 125 transmits the face information of the visitor photographed by the camera 113 to the resident smartphone 2 (s114). Thus, the resident can confirm the face information of the visitor transmitted to his smartphone 2 (s116). Thus, if the visitor is a visitor who needs to open the door, the resident operates his / her smartphone 2 to transmit the door open signal to the controller 125 (s118).

As a result, when receiving the door open signal, the control unit 125 accesses the password generating unit 123 to generate the one-time password as in the case where the telephone number is registered as described above (s104). The created one-time password is transmitted to the smartphone 1 of the visitor through the communication unit 124 (s106).

Accordingly, the visitor can confirm the password through his / her own smartphone 1, and can enter the password to open the door (s108) (s110).

As described above, according to the present invention, even if a visitor does not have a telephone number stored in advance in the telephone number storage unit 121, a one-time password can be provided to allow access when the user is authenticated as a legitimate visitor according to a resident identification process Able to know.

According to the present invention as described above, when opening a door lock device installed on a door, a phone number is firstly authenticated using a smartphone of the user, and then a second password is inputted again by the door lock device to be authenticated .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be apparent that modifications, variations and equivalents of other embodiments are possible. Therefore, the true scope of the present invention should be determined by the technical idea of the appended claims.
