As shown in FIG. 5 , the QR code 30 according to an embodiment of the present invention may be composed of a secret code 31 , a gender code 32 , and a date/time information code 33 .

Among the plurality of codes included in the QR code 30, the secret code 31 is a code for selecting only a QR code issued by an authenticated, that is, a true virtual ID issuance application, generated through a fake or similar application. The QR code corresponds to a code to block the crime of men breaking into women's restrooms without permission.

To this end, the secret code 31 may include a unique code consisting of mixed characters, symbols, etc. given by the application operation server 200 , and the password information of this secret code 31 is only available in the application operation server 200 . It may be generated and stored, and update information of the secret code 31 may be transmitted to the door opening/closing control device 100 .

Therefore, the door opening/closing control device 100 synchronized with the application operation server 200, more specifically, the controller 150 is this secret to the QR code scanned by the QR code scanner 130 of the door opening/closing control device 100 Even if the code is absent or the secret code is provided, the opening of the door 500 may not be allowed if it does not match the secret code generated by the application operation server 200 .

For reference, this secret code 31 included in the QR code issued by the application operation server 200 in response to a QR code generation request from the user terminal 300 may be implemented as (i) a code of a fixed value or , (ii) may be updated at a predetermined cycle (eg, daily, weekly, monthly, etc.), or (iii) may be implemented with a new secret code each time the QR code is issued.

In addition, among the plurality of codes included in the QR code 30 , the gender code 32 corresponds to a code for verifying that the gender of the user who is issued the QR code is female. Therefore, the controller 150 permits the opening of the door 500 when the corresponding gender is determined to be a male even if such a gender code is absent or a gender code is provided in the QR code scanned by the QR code scanner 130 . may not

Also, among a plurality of codes included in the QR code 30 , the date/time information code 33 may be used to determine the available valid time of the issued QR code. For example, the QR code illustrated in FIG. 5 has a date/time information code 33 of '2020.04.01 PM 2:34:56', so that the QR code is displayed at 2:34 PM on April 1, 2020. It may indicate information that it was issued at minute 56 seconds. For reference, the date information and time information included in the date/time information code 33 corresponds to information automatically received through GPS and has very high accuracy, and such date/time information includes the door opening/closing control device 100 and Since it is synchronized between the application operation servers 200 (that is, the date/time information in the door opening/closing control device 100 is the same as the date/time information in the application operation server 200), the door opening/closing control device 100 ) and the user inconvenience caused by the difference in time between the application operation server 200 and the application operation server 200 can be fundamentally blocked.

For example, the door opening/closing control apparatus 100 may set the effective use time of the QR code issued to the user terminal 300 . Therefore, the controller 150 is based on the issuance date and time information of the QR code 30 included in the date/time information code 33, the scan is attempted within a preset effective time (eg, 30 seconds) Only in this case, the door opening/closing control of women's restrooms in general buildings can be executed.

Alternatively, according to another embodiment of the present invention, the effective use time of the QR code can be set in the door opening/closing control device 100, and the building manager can set the effective use time of the QR code through the display 120 is already as described. Therefore, the controller 150 determines whether the scanning time of the QR code is within a preset effective use time (eg, 30 seconds) from the issuance time of the QR code based on the date/time information code 33 included in the QR code. can be determined, and the opening of the door 500 can be allowed only within the effective use time.

Here, as shown in FIG. 5 , the QR code 30 according to an embodiment of the present invention includes only gender information as personal information, so it is possible to minimize the user's objection to the provision and leakage of personal information, and the QR code ( 30) is encrypted in the application operation server 200 and transmitted to the user terminal 300, and decryption is performed through software mounted on the door opening/closing control device 100, so that personal information security can be further strengthened.

Returning to FIG. 4 again, the QR code received from the application operation server 200 may be displayed on the user terminal 300 and scanned through the QR code scanner 130 of the door opening/closing control device 100 (S430). Since the operation, function, principle, and the like of scanning a QR code are substantially the same as those known in the art, a detailed description of the QR code scanning will be omitted in this paragraph.

The scanned QR code may be analyzed by the controller 150 and the controller 150 may generate a door opening/closing control signal based on the analyzed QR code (S440), and according to the generated door opening/closing control signal, the door ( 500) can be controlled to open and close (S450).

More specifically, the controller 150 identifies the secret code 31, the gender code 32 and the date/time information code 33 included in the received QR code, (i) the identified secret code 31 the QR code corresponds to a normal QR code issued through the virtual ID issuance application, (ii) the gender of the user who issued the QR code is female, and (iii) the issuance date and time information of the QR code. Based on the validity time condition (eg, 30 seconds, etc.), the opening of the door 500 may be allowed only when it is satisfied.

That is, the controller 150 according to an embodiment of the present invention allows the opening of the door 500 only when all three codes included in the QR code are satisfied (that is, any one of the three codes) It is characterized in that it generates a door opening/closing control signal that disallows the opening of the door 500 if the code condition is not met, and through this triple confirmation procedure, the psychological stability of female users using women's toilets in general buildings is significantly improved. can be improved

Here, according to an additional embodiment of the present invention, the method may further include determining whether the user terminal 300 requesting issuance of the QR code is a lost terminal. In order to prevent a woman's lost smart phone from being acquired and misused by men, according to an additional embodiment of the present invention, it is possible to additionally check whether the user terminal 300 is reported lost in the application operation server 200, and the user When the terminal 300 is identified as a lost terminal, the application operation server 200 satisfies the conditions of the above three codes by additionally generating a phone number and loss report terminal information in the QR code generated in the corresponding user terminal. even if (i) through the identified secret code 31, the QR code corresponds to the QR code issued through the virtual ID issuance application, (ii) the gender of the user who issued the QR code corresponds to a female; And (iii) even if the validity time condition of the QR code is satisfied, the opening of the door 500 may not be allowed.

In this case, the application operation server 200 according to an embodiment of the present invention may be further communicatively coupled with an institution such as a police station, and when a request to enter the women's restroom is confirmed using the user terminal reported as lost By immediately transmitting the location information of the door opening/closing control device 100 to the police station, it is possible to significantly contribute to the arrest of preliminary criminals and the reduction of crime.
