Description

Smart Door {SMART DOOR}

The present invention relates to a smart door that performs authentication using disposable authentication information when the first authentication fails.

The existing front door is equipped with a mechanical door lock, and has simply functioned as a locking means and opening/closing means.

However, in recent years, electronic door locks or digital door locks have been developed to provide a lock/unlock function that is easier to use, and smart doors that provide various information and aesthetic elements and perform security functions are also appearing. .

In addition, since it has evolved from the conventional method of performing authentication using a button key, recently, a smart door using a simple and improved security authentication means such as biometric authentication has appeared.

Meanwhile, most of the devices that unlock the door lock by biometric authentication have a function of switching to a fixed password input when biometric authentication fails.

In terms of security, since the door lock is eventually released by entering a fixed password, such a device can be viewed as the same product as a conventional system that releases the door lock by entering a fixed password.

Therefore, when biometric authentication fails, it is required to perform authentication using a means other than a fixed password.

An object of the present invention is to provide a smart door that prevents lowering of security even when biometric authentication fails.

In addition, an object of the present invention is to provide a smart door with improved security by preventing the transmission of disposable authentication information to multiple people.

In addition, an object of the present invention is to provide a smart door that can prevent a disposable password from becoming a fixed password.

The smart door according to an embodiment of the present invention transmits one-time authentication information to a user's account when authentication using authentication data fails, and unlocks the smart door when the one-time authentication information is input.

A smart door according to an embodiment of the present invention displays a list of users corresponding to a plurality of account information, and transmits one-time authentication information to a selected user's account.

The smart door according to an embodiment of the present invention unlocks the smart door when disposable authentication information is input within a preset time.

When biometric authentication fails, if the user is prompted to input a fixed password, a problem of lowering security occurs. However, according to the present invention, when the first authentication fails, additional authentication is performed using one-time authentication information instead of fixed authentication information, so that even when biometric authentication fails, the security can be prevented from deteriorating. Further, according to the present invention, registration of account information is performed by a member, and one-time authentication information is transmitted only to users corresponding to the registered account information. That is, according to the present invention, there is an advantage in that it is possible to improve security by preventing any person from receiving the one-time authentication information and transmitting the one-time authentication information only to those who have been registered in advance.

In addition, according to the present invention, by transmitting the one-time authentication information only to a specific user among a plurality of users who have registered account information, there is an advantage of preventing the one-time authentication information from being transmitted to several people and improving security.

In addition, according to the present invention, the door lock is released only when one-time authentication information is generated and an input for authentication is received within a preset time. In other words, since the user who performed the first authentication using biometric data in front of the smart door is located near the door lock anyway, it does not cause inconvenience to the user even if a preset time limit is set. There is an advantage of preventing the password from becoming a fixed password.

In this case, it may include transmitting the one-time authentication information to the user's account (S350) and unlocking the smart door (S370) when the input for authentication corresponds to the one-time authentication information.

First, the step of storing account information (S310) will be described with reference to FIG. 4.

4 is a diagram illustrating a method of storing account information by a smart door according to an embodiment of the present invention.

The processor of the smart door 200 may store user account information in a memory.

The account information may mean identification information of a place where the one-time authentication information is to be transmitted. For example, the account information may mean a user's email address or a phone number of a user's terminal.

In this case, the processor of the member's terminal 100 may receive an input of the user's account information. In addition, the processor of the member's terminal 100 may transmit the user's account information to the smart door 200 through the communication unit.

In addition, the processor of the smart door 200 may receive a plurality of account information from terminals of one or more members through a communication unit.

For example, the processor of the smart door 200 may receive first account information corresponding to the first member (dad) from the terminal of the first member (dad). In addition, the processor of the smart door 200 may receive second account information corresponding to the second member (mother) and third account information corresponding to the third member (son) from the terminal of the second member (mother). .

In addition, the processor of the smart door 200 may receive user account information including members and visitors from terminals of one or more members through the communication unit.

For example, the processor of the smart door 200 may receive first account information corresponding to the first member (dad) from the terminal of the first member (dad). In addition, the processor of the smart door 200 may receive second account information corresponding to the second member (mother) and third account information corresponding to the first visitor (friend) from the terminal of the second member (mother). .

Meanwhile, the processor of the smart door 200 may store user account information in a memory.

When a plurality of account information respectively corresponding to a plurality of users is received, the processor of the smart door 200 may store a plurality of account information corresponding to each of the plurality of users in a memory.

For example, when first account information corresponding to a first member (dad), second account information corresponding to a second member (mother), and third account information corresponding to a first visitor (friend) are received, smart The processor of the door 200 stores first account information corresponding to the first member (dad), second account information corresponding to the second member (mother), and third account information corresponding to the first visitor (friend). Can be saved on.

Meanwhile, it was explained that the member's terminal inputs account information, and the member's terminal transmits the account information to the smart door.

However, the present invention is not limited thereto, and the processor of the smart door 200 may receive an input of the user's account information through the input unit. In this case, the processor of the smart door 200 may store the input account information in the memory.

Next, an operation S330 of acquiring user authentication data will be described with reference to FIG. 5.

5 is a diagram illustrating a method of authenticating a user according to an embodiment of the present invention.

The sensing unit 220 of the smart door 200 may obtain authentication data for user authentication.

Here, the authentication data may be biometric data. In addition, by using any one of various sensors, the sensing unit 220 of the smart door 200 may acquire the user's biometric data.

On the other hand, user authentication data is not limited to biometric data, and data capable of authenticating a user and distinguishing a specific user from other users is sufficient. However, in the following description, the authentication data is assumed to be biometric data.

Meanwhile, the processor of the smart door 200 may authenticate the user based on the authentication data acquired by the sensing unit 220.

As an example, when the registered user's biometric data is stored in the authentication server, the processor of the smart door 200 may transmit the visitor's biometric data acquired by the sensing unit 220 to the authentication server through the communication unit.

In this case, the authentication server may perform authentication using the biometric data received from the smart door 200 and the visitor's biometric data stored in the server.

Specifically, the server may compare biometric data of registered users with biometric data received from the smart door 200. In addition, when the biometric data of a specific visitor and the biometric data received from the smart door 200 match among the registered visitors' biometric data, the server may transmit an authentication result indicating that the authentication was successful to the smart door 200.

Meanwhile, it has been described that the authentication is performed in the authentication server, and the authentication server transmits the authentication result and visitor information to the smart door 200, but is not limited thereto.

Specifically, when the registered user's biometric data is stored in the smart door 200, the processor of the smart door 200 stores the biometric data obtained from the sensing unit 220 and the registered user's biometric data stored in the memory 250. You can use it to perform authentication.

Specifically, the processor of the smart door 200 may compare the biometric data stored in the memory with the biometric data acquired by the sensing unit 220. In addition, if the biometric data of a specific visitor among the biometric data stored in the memory matches the biometric data acquired by the sensing unit 220, the processor of the smart door may determine that the authentication is successful.

Meanwhile, when authentication is successful, the processor 270 may control the door lock 260 so that the smart door 200 is unlocked.

6 is a diagram for describing a method of operating a smart door when authentication fails.

The processor of the smart door may determine that authentication has failed.

Specifically, when the registered user's biometric data and the biometric data acquired by the sensing unit 220 do not match, the processor of the smart door may determine that authentication has failed.

In another embodiment, when the processor acquires biometric data more than a preset number of times through the sensing unit 220, and the biometric data obtained more than a preset number of times does not match the registered biometric data (biometric data of a registered user) It can be determined that authentication has failed.

For example, when the preset number of times is two, the processor may receive the first biometric data through the sensing unit 220 and compare the first biometric data with the registered biometric data. In addition, when the first biometric data does not match the registered biometric data, the processor may output a notification.

Then, the processor may receive the second biometric data through the sensing unit 220 and compare the second biometric data with the registered biometric data. In addition, when the second biometric data does not match the registered biometric data, the processor may determine that authentication has failed.

Authentication failure can occur for a variety of reasons.

As a first example, when incomplete biometric data is acquired from the sensing unit 220 due to a system problem or an environmental problem, the smart door may fail to authenticate.

As a second example, when an unregistered user attempts authentication while inputting biometric data to the sensing unit 220, the smart door may fail to authenticate.

If authentication fails according to the first example, no problem occurs if the user is prompted to enter a fixed password and then unlocks the door lock.

However, if authentication fails according to the second example, if the user is prompted to input a fixed password, an unregistered user can pass through the smart door after entering only the password, so it means performing authentication using biometrics. Will disappear.

Therefore, in order to solve this problem, the present invention uses one-time authentication information instead of a fixed password.

Specifically, when authentication fails, the processor may transmit one-time authentication information to the user's account. In this case, the processor controls the display unit 510 to display information indicating that authentication has failed as shown in FIG. 6, and when an input requesting issuance of one-time authentication information is received from the user, the user's account One-time authentication information can be transmitted.

Here, the one-time authentication information may be a one-time password (OTP) or a one-time QR code.

Specifically, the one-time authentication information may be a one-time password (OTP) or a one-time QR code that is discarded after being used once in order to reduce accidents exposed to danger after repeatedly using the same password. In addition, one-time authentication information may be generated randomly.

Meanwhile, the processor may transmit disposable authentication information to the user's account by using the account information.

Specifically, when authentication fails, the processor may generate one-time authentication information. In addition, the processor may transmit the one-time authentication information to an account corresponding to the account information by using the account information stored in the memory.

For example, if the father's phone number is stored in the memory, the processor may transmit disposable authentication information to the father's terminal by using the father's phone number stored in the memory.

For another example, if the father's email address is stored in the memory, the processor may transmit disposable authentication information to the father's email account by using the father's email address stored in the memory.

Meanwhile, since authentication has failed, the smart door does not know who is attempting to authenticate. Therefore, when a plurality of account information corresponding to each of a plurality of users is stored in the memory, the smart door does not know which account to transmit the disposable authentication information to.

In order to solve this problem, the smart door may display a list of users for which account information is registered, and transmit disposable authentication information based on a user's selection. This will be described with reference to FIG. 7.

7 is a diagram illustrating a method of selecting a user to receive one-time authentication information according to an embodiment of the present invention.

If authentication fails, the processor of the smart door may display a list representing users respectively corresponding to a plurality of account information.

Specifically, first account information, second account information, third account information, and fourth account information may be stored in the memory. In this case, the processor of the smart door is a first user corresponding to the first account information, a second user corresponding to the second account information, a third user corresponding to the third account information, and a fourth user corresponding to the fourth account information. The display unit 510 may be controlled to display a list including.

For example, the processor of the smart door may display a list including a father corresponding to the first account information, a mother corresponding to the second account information, a daughter corresponding to the third account information, and a son corresponding to the fourth account information. I can.

Meanwhile, the processor may receive an input for selecting a specific user from among users included in the list through the input unit.

And when an input for selecting a specific user from the list is received, the processor may transmit one-time authentication information to an account corresponding to the account information of the specific user.

For example, when an input for selecting a father from the list is received, the processor may transmit disposable authentication information to the father's terminal or the father's email address using the father's account information.

8 to 9 are views for explaining a method of inputting disposable authentication information according to an embodiment of the present invention.

The user's terminal 800 may display disposable authentication information 810.

For example, when one-time authentication information is transmitted to the user's terminal, the processor of the user's terminal 800 may display a text message or an app screen including the one-time authentication information.

For another example, when one-time authentication information is transmitted to the user's e-mail account and an input for opening the e-mail account is received, the processor of the terminal 800 may display a screen including the one-time authentication information.

Meanwhile, referring to FIG. 9, a user may input disposable authentication information into a smart door using the disposable authentication information displayed on the terminal 800.

Meanwhile, after transmitting the disposable authentication information to the user's account, the processor of the smart door may receive an input for authentication from the user.

In addition, when the input for authentication corresponds to the transmitted disposable authentication information, the processor of the smart door may control the door lock to unlock the smart door.

Specifically, when the one-time authentication information transmitted to the user's account is a one-time password (OTP), the processor may receive an input of the password from the user. In addition, when the received password matches the one-time password (OTP) transmitted to the user's account, the processor may control the door lock to unlock the smart door.

In addition, when the one-time authentication information transmitted to the user's account is a one-time QR code, the processor may receive an input of an image from the user. And, if the received image is a disposable QR code transmitted to the user's account, the processor may control the door lock to unlock the smart door.

Meanwhile, when the transmitted one-time authentication information and the input for authentication match and the smart door is unlocked, the processor may discard the generated (transmitted) one-time authentication information. Then, when generating the next one-time authentication information, the processor may generate one-time authentication information different from the discarded one-time authentication information.

Meanwhile, the processor of the smart door receives an input for authentication from a user within a preset time after transmitting the one-time authentication information to the user's account, and when the input for authentication corresponds to the one-time authentication information, the smart door is opened. The door lock can be controlled to unlock.

Meanwhile, when an input for authentication is not received from a user within a preset time, the processor may discard the generated (transmitted) disposable authentication information. Then, when generating the next one-time authentication information, the processor may generate one-time authentication information different from the discarded one-time authentication information.

Meanwhile, when a request for re-issuance is received from the user after transmitting the one-time authentication information to the user's account, the processor may generate the second one-time authentication information and transmit the generated second one-time authentication information to the user's account.

Specifically, when authentication information is not input within a preset time or when authentication information is not well identified, the user may provide a request for reissuance of disposable authentication information to the smart door.

In addition, when a request for re-issuance is received from the user after transmitting the one-time authentication information to the user's account, the processor may generate second one-time authentication information and transmit the generated second one-time authentication information to the user's account.

Here, the second one-time authentication information may be different from the previously generated one-time authentication information.

That is, if authentication information is not input within a preset time, the processor may discard the previously generated one-time authentication information. In addition, when a request for reissuance is received after a preset time, the processor may generate and transmit the second one-time authentication information to the user's account.

In addition, when a request for re-issuance is received within a preset time, the processor may discard the previously generated one-time authentication information, generate second one-time authentication information, and transmit it to the user's account.

Meanwhile, when authentication fails using an input for authentication, the processor may keep the smart door in a locked state and transmit a warning message to the terminal of the member.

Specifically, when the input for authentication and the disposable authentication information transmitted to the user's account do not match, the processor may keep the smart door in a locked state. In addition, the processor may transmit a warning message indicating that the user has failed authentication using the one-time authentication information to the member's terminal.

Meanwhile, when authentication information is not input within a preset time, the processor may determine that authentication has failed. Thus, the processor can keep the smart door in a locked state.

In the case of biometrics, authentication may fail due to systemic or environmental problems. However, according to the present invention, since the second authentication means is provided to the user, there is an advantage of improving user convenience.

In addition, when biometric authentication fails, if the user is prompted to input a fixed password, a problem of lowering security occurs. However, according to the present invention, when the first authentication fails, additional authentication is performed using one-time authentication information instead of fixed authentication information, so that even when biometric authentication fails, the security can be prevented from deteriorating.

Further, according to the present invention, registration of account information is performed by a member, and one-time authentication information is transmitted only to users corresponding to the registered account information. That is, according to the present invention, there is an advantage in that it is possible to improve security by preventing any person from receiving the one-time authentication information and transmitting the one-time authentication information only to those who have been registered in advance.

In addition, according to the present invention, by transmitting the one-time authentication information only to a specific user among a plurality of users who have registered account information, there is an advantage of preventing the one-time authentication information from being transmitted to several people and improving security.

In addition, according to the present invention, the door lock is released only when one-time authentication information is generated and an input for authentication is received within a preset time. In other words, since the user who performed the first authentication using biometric data in front of the smart door is located near the door lock anyway, it does not cause inconvenience to the user even if a preset time limit is set. There is an advantage of preventing the password from becoming a fixed password.

Next, a method of operating a smart door according to an embodiment of the present invention will be described.

A method of operating a smart door according to an embodiment of the present invention includes obtaining authentication data of a user, authenticating the user using the authentication data, and, in case the authentication fails, the user's account is disposable. And transmitting authentication information.

In this case, the step of transmitting the one-time authentication information may include generating the one-time authentication information when the authentication fails, and transmitting the one-time authentication information to an account corresponding to the user's account information stored in a memory. I can.

On the other hand, the transmitting of the one-time authentication information includes: displaying a list representing users respectively corresponding to a plurality of account information stored in a memory when the authentication fails, and receiving an input for selecting a specific user from the list If so, transmitting the one-time authentication information to an account corresponding to the account information of the specific user.

On the other hand, the step of authenticating the user may include obtaining the authentication data more than a preset number of times, and determining that the authentication has failed if the authentication data obtained more than the preset number of times does not match the registered authentication data. I can.

Meanwhile, after transmitting the one-time authentication information to the user's account, an input for authentication is received from the user, and when the input for authentication corresponds to the one-time authentication information, a door lock is opened to unlock the smart door. It may further include controlling.

In this case, the one-time authentication information is OTP, and the step of controlling the door lock to unlock the smart door includes receiving an input of a password from the user after transmitting the OTP to the user's account, and the password When the OTP corresponds to the OTP may include controlling the door lock to unlock the smart door.

Meanwhile, the one-time authentication information is a QR code, and the controlling of the door lock to unlock the smart door includes receiving an input of an image from the user after transmitting the QR code to the user's account, If the image corresponds to the QR code, it may include controlling the door lock to unlock the smart door.

On the other hand, controlling the door lock to unlock the smart door, wherein the input for authentication is received within a preset time after transmitting the disposable authentication information to the user's account, and the input for authentication It may include controlling the door lock to unlock the smart door when it corresponds to the disposable authentication information.

Meanwhile, if a request for re-issuance is received from the user after transmitting the one-time authentication information to the user's account, generating second one-time authentication information and transmitting the second one-time authentication information to the user's account are further performed. Can include.
