11 is a diagram for explaining authentication of registrant information according to an embodiment of the present invention, FIG. 12 is a view in which a screen is output for inputting a password when authenticating the registrant information, and FIG. 13 is a number of the keypad screen And a diagram for showing/hiding a character, and FIG. 14 is a diagram for explaining an input of a password of the registrant.

11 to 14, the sensing unit 220 of the smart door 200 may obtain biometric data for authentication (first authentication) of registrant information.

In detail, when a user is located within a certain distance from the smart door 200 for authentication of the registrant information, the user may be detected by the sensing unit 220.

When it is detected that the user is positioned in front of the smart door 200, the sensing unit 220 acquires biometric data for authentication (first authentication) of the registrant information.

Using any one of the various sensors described above, the sensing unit 220 of the smart door 200 may acquire the user's biometric data. Meanwhile, the data for authentication of the non-registrant is not limited to the biometric data of the non-registrant, and data that can authenticate the non-registrant and distinguish it from the registrant is sufficient.

Meanwhile, the processor 290 of the smart door 200 may perform authentication based on the biometric data acquired by the sensing unit 220.

When the user's biometric data is stored in the memory 260, the processor 290 of the smart door 200 includes the biometric data acquired by the sensing unit 220 and the registrant's biometric data stored in the memory 260. Authentication can be performed using.

Here, the biometric data of the registrant stored in the memory 260 may be understood as biometric data of the registrant.

Specifically, the processor 290 may compare the biometric data of the registrant with the biometric data acquired by the sensing unit 220.

When the biometric data of the registrant and the biometric data acquired by the sensing unit 220 match, the processor 290 may determine that the first authentication is successful.

If the processor 290 determines that the authentication is successful, the processor 290 may display (output) a phrase indicating that the authentication is successful on the display unit 241.

In addition, the processor 290 may read password information for inputting a password set by the registrant from the memory 260.

Here, the password information includes a password set by the registrant, an arrangement of numbers and characters of the keypad unit 255 set for input of the password (first keypad arrangement), and the numbers and characters of the keypad unit 255 are displayed/ It may be a hidden setting.

For example, when biometric data of a first registrant (dad), a second registrant (mother), a third registrant (son), and a fourth registrant (daughter) is stored in the memory 260 of the smart door 200, The processor 290 may compare the data acquired by the sensing unit 220 with biometric data of the first to fourth registrants. When the biometric data of the first registrant matches the biometric data acquired by the sensing unit 220, the processor 290 determines that authentication has been successful, and stores the password information of the first registrant in the memory 260 Can be read from.

The processor 290 may display (output) the first screen 242 and the third screen 247 on the display unit 241 to input the password of the registrant based on the password information.

In detail, the processor 290 may display an arrangement of the keypad units 255 set by the registrant on the third screen 247 on the third screen 247.

As shown in Fig. 13(a), when the registrant has set the password display setting, the processor 290 displays a third screen of the display unit 241 to display numbers and characters on the keypad unit 255. It can be displayed (printed) at (247).

On the other hand, as shown in FIG. 13(b), when the registrant has set the password hidden so that the numbers and characters of the keypad unit 255 are not visible, the processor 290 uses the numbers of the keypad unit 255. And characters may not be displayed (not output) on the third screen 247 of the display unit 241.

As illustrated in FIG. 12, when the first screen 242 and the third screen 247 are displayed on the display unit 241, the user may input a password.

Among the users, the registrant may input a preset password using the preset password pattern 259.

In this case, a password input by the user may be displayed on the number display unit 251 of the third screen 247.

Alternatively, the same number of symbols as the number of numbers input by the user may be displayed (output) on the number display unit 251 of the third screen 247.

For example, a symbol displayed on the number display unit 251 may be "*".

The processor 290 may perform authentication using a password input by the user and a password of a registrant stored in the memory 260.

Specifically, the processor 290 may compare the password input by the user with the password of the registrant stored in the memory 260. If the password input by the user matches the password of the registrant stored in the memory 260, the processor 290 may determine that the second authentication has been successful.

For example, after authentication of the biometric data of the first registrant is completed, the keypad unit 255 set by the first registrant is output on the display unit 241. When the password input by the user through a touch input to the output keypad unit 255 matches the password set by the first registrant, the processor 290 may determine that the second authentication is successful.

Meanwhile, when the first authentication and the second authentication are successful, the processor 290 may control the door lock 270 to unlock the smart door 200.

On the other hand, when the password input by the user and the password of the registrant stored in the memory 260 do not match, the processor 290 may determine that authentication has failed.

In this case, the processor 290 may control the door lock 270 to maintain the smart door 200 in a locked state.

15 is a diagram illustrating a keypad screen for inputting a password when the user is not registered.

Referring to FIG. 15, when the user fails the first authentication, the processor 290 may display (output) randomly arranged numbers and letters on the keypad unit 255.

Specifically, if the biometric data acquired by the sensing unit 220 does not match the biometric data stored in the memory 260, the processor 290 may determine that the first authentication has failed.

In addition, when it is determined that the first authentication has failed, the processor 290 may determine that the user is an unregistered person.

The processor 290 may display (output) the phrase that the user is an unregistered person on the display unit 241.

In addition, the processor 290 may output (display) numbers and characters that are secondarily randomly arranged on the keypad unit 255 of the display unit 241.

Here, when the user is a non-registered person, the arrangement of numbers and letters displayed on the keypad unit 255 may be defined as “second keypad arrangement”.

Specifically, the arrangement of the second keypad may be different from the arrangement of the first keypad set by the registrant.

Accordingly, even if the non-registrant sees the registrant inputting the password, numbers and letters of the second keypad array are displayed on the keypad unit 255, so that the same password as that of the registrant cannot be input.

In this case, the processor 290 may determine that the first authentication and the second authentication have failed, and control the smart door 200 to maintain a locked state.

That is, the non-registrant cannot enter the inner space of the smart door 200, so that security may be improved.

Hereinafter, a process of registering a user in the smart door 200 and a process of authenticating registrant information will be described.

16 is a flowchart illustrating a registration process of user information according to an embodiment of the present invention, and FIG. 17 is a flowchart illustrating authentication of registrant information according to an embodiment of the present invention.

Thereafter, the processor 290 may display (output) on the display unit 241 that the biometric data of the user is registered.

The user may set a password corresponding to the registered biometric data (S11). Here, the password corresponding to the registered biometric data may be understood as an individual password of the registrant after the user is registered as a registrant.

In detail, the user may set the individual password by selecting a password button 245b selectively displayed on the second screen 244 of the display unit 241.

Alternatively, the processor 290 stores the user's biometric data acquired by the sensing unit 220 in the memory 260, and then controls the third screen 247 for setting the personal password to be displayed. can do.

The user may input a personal password to be set on the keypad unit 255 of the third screen 247.

In this case, the processor 290 may control the number display unit 251 to output the password for each individual input by the user.

After inputting the personal password, the user may set the individual password by selecting the confirmation button 259.

Further, the processor 290 may not output the individual password to the number display unit 251 after the user inputs the individual password.

The user may perform the step of verifying the personal password (S12).

In detail, the user may input the same password as the input password for each individual into the keypad unit 255 again.

When the password input by the user in S11 matches the password input in S12, the processor 290 may store the personal password of the user in the memory 260. In this case, the user's personal password may be stored corresponding to the registrant's biometric data.

The processor 290 may output the individual password pattern 259 to the display unit 241 so that the individual password of the set user can be easily input.

The individual password patterns 259 output by the processor 290 may be plural, which may be understood as a "recommended password pattern".

The user may select any one of a plurality of recommended patterns of the password.

Alternatively, the user may directly select the pattern 259 of the individual password.

The user may set a pattern 259 of the selected individual password (S14). The processor 290 may store the set password pattern 259 in the memory 260.

Here, the password pattern 259 may be stored in correspondence with the registrant's biometric data and an individual password.

In addition, the user may set whether or not numbers and characters are displayed on the keypad unit 255 (S15). In detail, the user may select and set any one of the password display setting or the password hiding setting.

The processor 290 may store any one of the items selected by the user in the memory 260.

After passing through all of the above processes, the user can be classified as a registrant.

Referring to FIG. 17, the smart door 200 may authenticate a registrant.

When a user is detected within a certain distance from the smart door 200, the processor 290 may control to perform authentication of the registrant.

The processor 290 may perform the user's biometric information authentication for the first authentication (S20). In detail, the processor 290 may acquire the user's biometric data by the sensing unit 220.

The processor 290 may determine whether the user is a registrant by using the biometric data acquired by the sensing unit 220 (S21).

In detail, the processor 290 may compare the biometric data obtained by the sensing unit 220 with the biometric data of the registrant stored in the memory 260.

When the biometric data acquired by the sensing unit 220 matches any one of the biometric data stored in the memory 260, the processor 290 may determine that the user is a registrant.

When it is determined that the user is the registrant, the processor 290 may output the arrangement of the keypad units 255 set by the registrant for the second authentication to the display unit 241 (S22).

The arrangement of the keypad unit 255 may be an arrangement stored in the memory 260 corresponding to the biometric data of a registrant that matches the biometric data acquired by the sensing unit 220.

The user may input a password by using the arrangement of the keypad units 255 output on the display unit 241 (S23).

The processor 290 may determine whether the user is a registrant using the password input by the user (S24).

In detail, the processor 290 may compare the password input by the user and the password stored in the memory 260.

The password stored in the memory 260 may be a personal password of the registrant corresponding to the biometric data of the registrant.

When the password input by the user matches the individual password of the registrant, the processor 290 may determine that the user is the registrant.

In this case, the processor 290 may release the door lock 270 so that the smart door 200 is unlocked (S241).

On the other hand, when the password input by the user does not match the individual password of the registrant, the processor 290 may determine that the user is a non-registrant.

In this case, the processor 290 may control the door lock 270 to lock the smart door 200 (S242).

Meanwhile, when the biometric data obtained by the sensing unit 220 does not match all of the biometric data of the registrant stored in the memory 260, the processor 290 may determine that the user is an unregistered person.

When it is determined that the user is an unregistered person, the processor 290 may output a randomly arranged keypad unit 255 to the display unit 241 (S25).

The random arrangement of the keypad unit 255 may be different from the arrangement of the registrant’s keypad unit 255.

Since the user is an unregistered user, the processor 290 may determine that the user is an unregistered user regardless of any password input to the keypad unit 255.

The processor 290 may control the door lock 270 to maintain the smart door 200 in a locked state (S26).

Since the user of the smart door 200 according to the embodiment of the present invention can enter the internal space of the smart tor 200 only when the first authentication and the second authentication are successful, security through a complex authentication process Sex can be improved.

In addition, since the registrant can easily input the password by using the pattern of the password set in the second authentication, convenience of the registrant can be increased.

In addition, since the arrangement of the keypad unit 255 set by the registrant can be displayed on the display unit 241 only when the user succeeds in the first authentication, the non-registrant enters the password close to the registrant's password. Can be prevented.

In addition, since characters displayed on the keypad unit 255 can be hidden according to the setting of the registrant, it is difficult for the non-registrant to find out the password of the registrant, thereby improving security.

In addition, in the case of the non-registrant, a keypad having a random character arrangement is provided to prevent the non-registrant from entering the password of the registrant, thereby further improving security.
