The door lock of the method of entering a password is relatively inexpensive, and it is convenient to inform other people (eg, friends, landlords, courier drivers, meter readers, etc.), but it is easy to leak through various channels. The method of reading the user's biometric information is expensive, and there is a problem that the access of other people authenticated by the household member is fundamentally blocked because the access of the unregistered person is impossible. As another method, there is a method of opening and closing the door lock using an electronic key or an electronic tag, but it is likely to be neutralized by theft or unauthorized copying of the electronic key or electronic tag.

As of 2017, the number of single female households exceeded 2.8 million, and is expected to exceed 3.8 million by 2045. In addition, according to a 2016 National Statistical Office survey, 46% of women in a single female household answered that they were uneasy about social safety, and 37% of them cited crime as an anxiety factor. According to the Criminal Policy Research Institute, a single female household is 11.2 times more likely to suffer damage from residential intrusion than the same male household. In addition, according to the National Police Agency, a total of 71,868 crimes related to housing intrusion from 2014 to 2017 reached a total of 1,310 cases in the last four years following the invasion of housing, with 99.8% being male perpetrators. There is a demand for a door lock device that is convenient to use while enhancing security for the household members of single female furniture.

1 is a block diagram illustrating a security reinforced door lock according to the present invention.

Referring to FIG. 1, the security reinforced door lock according to the present invention includes a keypad 110 and a lever 120 exposed to the outside of the door lock device 100, and a lock unlocking means 130 installed inside the door lock device 100. , A warning unit 140, a memory unit 150, a short-range communication module 160, a security code reader unit 170, a security code/password update unit 180, and a lock release control unit 190.

The front of the door lock device 100 is provided with a keypad 110 on which numeric keys for inputting a password are arranged, and a lever 120 for opening and closing a door. The keypad 110 may include a physical numeric keypad, a touch key, and a touch screen on which a numeric key icon supporting TUI (Touch User Interface) is displayed. Like a normal door lock, a voice signal notifying the unlocking state is output at the moment the door lock is unlocked by the lock unlocking control unit 190, and at this time, the operation lock state of the lever 120 is released, and the user manipulates the lever 120 to enter the door. Can be opened.

Locking and unlocking means 130 is a means for locking or unlocking the entrance door. For example, a solenoid or an electric motor is provided inside the door lock device 100, and the door is locked or unlocked by inserting or retracting the latch installed in the door frame by moving the latch installed on the door back and forth.

The warning unit 140 may be a buzzer or speaker that generates a warning sound, or may be composed of a warning light, an LED, etc. that visually warn. The warning unit 140 outputs a warning sound or turns on a warning lamp when it is determined that the security code does not match or the password does not match by the lock unlocking control unit 190.

The memory means 150 includes a password storage unit 152 that stores a password specified by a user, and a security code storage unit 154 that stores a security code updated by a security code/password update unit 180 to be described later. Includes. The memory means 150 may be formed of a flash memory or the like.

The short-range communication module 160 is a means for communicating with the user portable terminal 200 through a wireless local area network. The short-range communication module 160 may be composed of, for example, a module such as Radio Frequency Identification (RFID), Bluetooth, Wi-Fi, and Zigbee.

The security code reader 170 is a means for reading a security code when the user portable terminal 200 enters within the communication radius of the short-range communication module 160.

The security code/password update unit 180 updates the security code and password only after the lock unlocking control unit 190 determines that the security code matches and switches the door from the locked state to the unlocked state. When the lock unlocking control unit 190 determines that the password matches and unlocks the door, neither the security code nor the password is updated. The security code/password update unit 180 transmits the updated security code and password to the user portable terminal 200. Then, the updated security code is stored in the security code storage unit 154, and the updated password is stored in the password storage unit 152.

Security codes are electronically readable data and are encrypted key information. A password is a series of numbers or data representing a series of numbers. For example, a new password updated by the security code/password update unit 180 is an encryption process of data representing a series of numbers.

In the present invention, the security code is used once and then updated and used as a one-time use. In addition, the subject of updating the security code is a door lock device that is not directly connected to the web, and is transmitted to the security management server 500 by relay of the user's portable terminal 200. This provides the advantage of being able to manage the security code with a high level of security, preventing the leakage of the security code through the web, and facilitating the management of the security code.

In the present invention, the password is temporarily used until the security code is updated. The password is used when the user's portable terminal 200 is absent, or when the user wants to allow access to another person (hereinafter referred to as'guest'). Multiple passwords can be used, and once used passwords are discarded so that unauthorized access can be prevented even if the password is leaked.

When transmitting the updated security code and password to the user portable terminal 200, the security code/password update unit 180 encrypts and transmits the updated security code and password. In addition, when the user portable terminal 200 relays the updated security code and password to the security management server 500, it may not be stored by itself or may be programmed to be deleted from the temporary storage. Alternatively, the security code/password update unit 180 may relay the updated security code and password to the remote security management server 500 and then transmit the user portable terminal 200 including command data for deletion. Therefore, it is possible to prevent leakage of a security code or password through hacking of the user's portable terminal 200. In addition, by updating the password together with the security code (even if the password is not used), it is possible to prevent unauthorized intrusion due to the leakage of the password as much as possible by giving a temporary property to the password.

The locking and unlocking control unit 190 is a means for controlling the operation of the locking and unlocking means 130. The lock and unlock control unit 190 determines whether the security code read from the security code reader unit 170 matches the security code stored in the security code storage unit 154 and switches the unlocking unit 130 from the locked state to the unlocked state. Control to do it. For example, when a user executes a door lock management app on the user's portable terminal 200, a new security code is issued from the security management server 500 to be described later, and the security code reader unit 170 ), it is possible to determine whether the security code matches.

Alternatively, the unlocking control unit 190 determines whether the password input by the user matches the password stored in the password storage unit 152 and controls the unlocking unit 130 to switch from the locked state to the unlocked state. For example, in a state in which the user loses or does not bring the user's portable terminal 200, accesses the security management server 500 to be described later using another portable terminal or other communication terminal such as a notebook, and undergoes user authentication. You can check the new password. In addition, if the user directly inputs the password while activating the touch screen of the keypad 110 of the security reinforced door lock 100 after reading the password, the unlocking control unit 190 may determine whether the password matches.

On the other hand, if the security code or password does not match, the unlocking control unit 190 operates the warning unit 140 described above.

Here, the lock unlocking control unit 190 determines whether the password matches or not and after unlocking the lock unlocking means 130, it determines a predetermined condition and temporarily stops the function of using the password. That is, after the password is used and a predetermined condition is satisfied, only whether the security code matches or not is determined to operate the lock unlocking means 130.

And after unlocking the lock unlocking means 130 by the use of the security code, since the security code/password update unit 180 generates a new security code and password, the password use function is activated again. Therefore, the use of passwords can be limited to temporary use.

Here, the security code/password update unit 180 may generate a plurality of different passwords when updating the password. For example, if you use a password of 6 digits, create two passwords '123456' and '345678'. And after the password is updated, after unlocking the unlocking means 130 for any one password (for example, '123456'), the lock unlocking control unit 190 discards the corresponding password and discards the remaining password (for example, '123456'). 345678') is controlled so that the door lock can be opened. That is, by discarding the used password, it is possible to prevent the same password from being leaked and reused.

For example, the head of a household or an administrator can allow access by giving a password '123456' to a maintenance person, and giving the courier the password '345678' to allow access. However, by discarding the used password, re-entry by the same password can be prevented, thereby preventing a crime due to password leakage.

As another example, the unlocking control unit 190 may set a predetermined usage time for any one password (eg, '123456'). For example, if the use time of the password '123456' issued to the maintenance person is set to 5 minutes, the maintenance person can freely access the house or facility in which the door lock of the present invention is installed within 5 minutes. However, by discarding the password after the usage time has elapsed, the issued password cannot be reused after the allowed time, thereby preventing unauthorized access by the same password.

In the security-enhanced door lock of the present invention, the door lock device is not directly connected to the web or mobile communication network. The security-enhanced door lock only connects to the user portable terminal 100 through short-range wireless communication. In addition, the security reinforced door lock directly updates the security code and password (one or a plurality of different passwords), and transmits the updated security code and password to the remote management server 500 through relay of the user's portable terminal 200. do. Therefore, it is possible to prevent the security code and password from being leaked through the web.

An advantage of the security-enhanced door lock of the present invention having a dual unlocking function of a security code and a password is that security can be enhanced while providing user convenience. Users can freely enter and exit by using the security code stored in their mobile terminal. Alternatively, it is possible to allow restricted access by authorized users by notifying others of the password provided temporarily.

The advantages of the security-enhanced door lock of the present invention and the advantages and specific embodiments of the door management system using the security-enhanced door lock will be described in detail with reference to FIGS. 2 to 13.

2 is a flow chart showing an example of operation of a door lock using a security code in the present invention, Figure 3 is a flow chart showing an example of operation of the door lock using a password in the present invention. A method of operating the security reinforced door lock according to the present invention will be described with reference to FIGS. 2 and 3 as follows.

Referring to FIG. 2, the lock unlocking control unit 190 determines whether the user portable terminal 200 has entered within a wireless communication radius of the short-range communication module 160 (ST110). For example, when a user manipulates the user's portable terminal 200 to execute a dedicated app, the short-range communication module 160 may be activated. As another example, when the user portable terminal 200 is detected, the short-range communication module 160 may be activated.

Thereafter, the security code reader unit 170 reads the security code from the user portable terminal 200 (ST120). Then, it is determined whether the read security code matches the security code previously stored in the security code storage unit 154 (ST130). If not, the warning unit 140 is operated as described above (ST140).

If it is determined in step ST130 that the security codes match, the door lock is unlocked (ST150). At this time, the unlocked state of the door lock may be output as a beep sound or other audio signal.

Thereafter, the security code/password update unit 180 updates the security code and password as described above, and stores the updated security code and password in the security code storage unit 154 and the password storage unit 152, respectively (ST160). ). Then, the updated security code and password are encrypted and transmitted to the user's portable terminal 200 (ST170).

Here, one of the important points is that the security code and password are updated in the door lock itself, and the updated security code and password are transmitted only through the wireless local area network 300. If the door lock directly transmits the security code to the remote management server through the web, the security code may be leaked through the public network. However, the security-enhanced door lock of the present invention automatically updates the security code and password whenever the security code is used, and the user portable terminal 200 uses the updated security code and password as in the door security management system to be described later. By relaying to the remote security management server 500 and not remaining on its own, the updated security code and password are prevented from being leaked through the web, and at the same time, security can be greatly enhanced by not remaining on the user's portable terminal.

Also, another important point is that even though only the security code is used, the password is also updated when the security code is updated. In this way, when the security code is used, the security code and the password are updated together in the door lock itself, thereby reducing the risk of exposure to an unused password being maintained for a long time without being updated.

Referring to FIG. 3, the unlocking control unit 190 determines whether a password is input through the keypad 110 (ST210). If the password is input, it is determined whether the password input in the next step matches the password stored in the password storage unit 152 (ST220).

If the passwords do not match, it is determined whether the number of times the passwords do not match continuously reaches a predetermined number of times (eg, 5 times) (ST230). If it is determined as'Yes' in step ST230, the warning unit 140 is operated (ST240).

If it is determined in step ST220 that the passwords match, the door lock is unlocked (ST250). At this time, the unlocked state of the door lock may be output as a beep sound or other audio signal.

When the door lock is opened by the password, the lock unlocking control unit 190 determines a predetermined condition and temporarily suspends the function of using the password. That is, afterwards, the door lock cannot be opened by inputting the password. A specific example of discarding and temporarily suspending the used password will be described later with reference to FIGS. 4 and 5.

Next, it is determined whether the door lock is unlocked using the security code (ST260). The process of unlocking the door lock using the security code has been described with reference to FIG. 2.

If the door lock is unlocked using the security code, ST160 and ST170 of FIG. 2 are performed, and when the security code and password are updated and transmitted to the user portable terminal 200, the previous password usage history is transmitted (ST270). ). Therefore, as described later, it is possible to store and manage the password usage history in the remote management server.

4 is a flow chart showing an example in which a plurality of passwords are used and discarded in the present invention, and FIG. 5 is a flow chart showing an example of discarding after setting a use time of a password in the present invention.

As described above, the security code/password update unit 180 may generate one or more passwords while updating the security code and password. In addition, as illustrated in FIG. 4, the lock unlocking control unit 190 may allow each of the plurality of passwords to be used only once or limit the number of times of use thereof. As another example, the unlocking control unit 190 may limit the use time for one password as illustrated in FIG. 5.

First, referring to FIG. 4, the lock unlocking control unit 190 may discard a password used after step ST250 of FIG. 3 is ended (ST410). Then, it is determined whether all passwords have been revoked (ST420). If there is a residual password, the process proceeds to step ST210. If the security code is used by the user after any one of the passwords has been used, the process may proceed to step ST260 even after step ST420.

For example, if two passwords '123456' and '345678' are newly created, and the password '123456' is input in step ST210 of FIG. 3, the password '123456' is released in step ST410 after unlocking the door lock of ST250. Will be discarded. Since the remaining password '345678' exists, the process proceeds to step ST210 to wait for a new password to be input. And if the security code is used, the security code and password will be updated through steps ST260 and ST270.

Assume that both passwords '123456' and '345678' are used before the security code and password are updated. Since the password '345678' is discarded in step ST410 and the condition of step ST420 is satisfied, the lock unlocking control unit 190 proceeds to step ST430 to temporarily stop the password use function (ST430).

Subsequently, until the security code is used in step ST260, the door lock cannot be unlocked by the password. After steps ST260 and ST270 are performed, a new password(s) is issued so that the door lock unlocking function based on the password will be reactivated.

Next, referring to FIG. 5, the lock unlocking control unit 190 may set a reuse time of a password used after step ST250 of FIG. 3 is ended (ST510). The reuse time is set by the user's designation. For example, the user can set the reuse time of the password by inputting a time of about 5 to 10 minutes by pressing a button inside the door lock. Alternatively, although not illustrated and illustrated, the number of times the password is reused may be set.

In the next step, it is determined whether the reuse time of the corresponding password has elapsed (ST520). This step may be replaced by a step of determining whether the number of reuse of the password exceeds a set number of times. Until the reuse time elapses (or until the number of reuse is exceeded), the process returns to step ST210 and the corresponding password can be reused. If the security code is used by the user during the process of determining whether the reuse period has elapsed, step ST260 may be performed.

If, in step ST520, it is determined that the reuse time for a certain password has elapsed or the number of times of reuse has been all counted, the password is discarded (ST530). Then, the process proceeds to step ST540 to determine whether all passwords have been revoked. If there is a residual password, the process proceeds to step ST210. If the security code is used by the user even in the middle of any step, the process may proceed to step ST260.

If it is determined in step ST540 that all of the one or more passwords have been discarded, the unlocking control unit 190 proceeds to step ST550 to temporarily stop the password use function (ST550).

Subsequently, until the security code is used in step ST260, the door lock cannot be unlocked by the password. After steps ST260 and ST270 are performed, a new password(s) is issued so that the door lock unlocking function based on the password will be reactivated.

The user portable terminal 200 may be a dedicated terminal for implementing the door security management system of the present invention, but is preferably a smart phone. A dedicated app for managing the security code may be installed on the user's portable terminal 200.

Although not shown, the user portable terminal 200 includes a short-range wireless communication module for communicating with the security enhanced door lock 100. For example, the short-range communication module may be composed of modules such as Radio Frequency Identification (RFID), Bluetooth, Wi-Fi, and Zigbee. In addition, the user portable terminal 200 includes a mobile communication module for communicating with the security management server 500. For example, the mobile communication module may be a module for performing mobile communication in a known communication frequency band such as 3G, 4G, and 5G, or a module for performing mobile communication in a next-generation communication frequency band that is not yet known. For example, the mobile communication module 230 is a Global System for Mobile communication (GSM), Code Division Multi Access (CDMA), Code Division Multi Access 2000 (CDMA2000), Enhanced Voice-Data Optimized or Enhanced Voice-Data Only (EVDO). ), WCDMA (Wideband CDMA), HSDPA (High Speed Downlink Packet Access), HSUPA (High Speed Uplink Packet Access), LTE (Long Term Evolution), LTE-A (Long Term Evolution-Advanced) It is a module that transmits and receives a radio signal with at least one of a base station, an external terminal, and a server.

In addition, the user portable terminal 200 includes a memory means for storing a security code and a password issued from the security management server 500. Typically, a smart phone includes the listed short-range communication module, mobile communication module, memory, and the like. In addition, they are already paying bills for mobile communications and wireless Internet. That is, the smart phone installs and executes a door lock management app, which will be described later with reference to FIGS. 8 to 13, and is equipped with an optimal environment for implementing the door security management system according to the present invention. Therefore, it is easy to realize the security code/password issuance request, relay, door lock opening, user management, door lock function setting, etc. described in the present invention by simply providing the door lock management app to the mobile terminal that the user is already using. Do.

In the present invention, the user portable terminal 200 only relays the security code and password updated in the security enhanced door lock 100 to the remote security management server 500, but does not store itself. And the door lock management app installed in the user's portable terminal 200 is the security management server 500, the security code and password updated by step ST170 of Figure 2 from the security-enhanced door lock 100, and information including each use history. It can be programmed to delete self-updated security codes and passwords after sending to.

The security management server 500 communicates with the user portable terminal 200 through the wide area mobile communication network 400. Referring to FIG. 6, the security management server 500 includes a security code management database 510 for storing and managing security codes for each security-enhanced door lock 100, and a password for storing and managing passwords for each security-enhanced door lock 100. A management database 520 and a security history management database 530 for storing and managing the history of issuing and using security codes and passwords for each security-enhanced door lock 100 are provided. The security code management database 510, the password management database 520, and the security history management database 530 may be a storage space installed in the security management server 500 or may be implemented as a separately managed database server.

In the present invention, the security management server 500 does not directly generate a security code and password. It merely stores and manages the security code and password (updated itself from the security-enhanced door lock) relayed through the user's portable terminal 200.

When there is a security code issuance request from the user portable terminal 200, the security management server 500 transmits the latest security code stored in the security code management database 510 to the user portable terminal 200 after an authentication procedure. .

For example, when the user runs the door lock management app on the user's portable terminal 200, an authentication request is automatically transmitted to the security management server 500. The security management server 500 may recognize the phone number or Mac address of the user portable terminal 200 and issue a security code.

In addition, when the user accesses the web using a computer terminal capable of Internet, the security management server 500 checks the user's ID and password or confirms the public certificate to provide the user with the latest information stored in the password management database 520. You can guide your password.

6, the door security management system of the present invention includes a security management server 500 or a user portable terminal 200 connected to a security management server 500 through a wide-area mobile communication network 600, a police agency server 700, a guardian portable terminal 800 , Or other server or terminal, etc. may be further included.

The door lock management app installed on the user's portable terminal 200 is a security management server 500, a National Police Agency server 700, when a user inputs a specific key, a key combination, and an emergency notification icon arranged on the app execution screen. Alternatively, an emergency message may be transmitted to the guardian's portable terminal 800. For example, when a household member of a single female household is waiting to open an entrance door, or when a molester approaches the entrance door, an emergency message may be transmitted to the security management server 500 or to a predetermined server or terminal.

In addition, the user portable terminal 200 may transmit an emergency message to the security reinforced door lock 100 through the wireless local area network 300. At this time, the security reinforced door lock 100 may be switched to stop the function of unlocking the door lock by the security code and unlock the door only by entering a password. Accordingly, it is possible to prevent the user's portable terminal 200 from being stolen and unlocking the door lock without permission by the takeover.

7 is a data flow diagram illustrating a method for managing security of a door according to the present invention. Referring to FIG. 7, a data flow between components constituting the door security management system of the present invention will be described as follows.

When the user runs the door lock management app on the user's portable terminal 200 to open the door, a security code issuance request signal is transmitted from the user's portable terminal 200 to the security management server 500 (step ①). The security management server 500 issues a security code through an authentication procedure for the user portable terminal 200 (step ②).

After the user's portable terminal 200 approaches within the short-range wireless radius of the security-enhanced door lock 100, the user inputs a door open icon on the app screen, or the lock unlocking control unit 190 in the security-enhanced door lock 100 When is automatically activated, the security reinforced door lock 100 reads the security code stored in the user's portable terminal 200 (step ③). The security reinforced door lock 100 determines whether the read security code matches a previously stored security code (step ④).

When a user directly inputs a password through the keypad 110 provided in the security reinforced door lock 100 by replacing steps ① to ④, it may be determined whether the password input by the user matches a previously stored password. Yes (step ⑤).

If it is determined that the security code matches through steps ① to ④, the door lock is unlocked, the security code and password are updated, and then stored in the security code storage unit 154 and the password storage unit 152, respectively (step ⑥).

Then, the security reinforced door lock 100 transmits the updated security code and password to the user portable terminal 200 (step ⑦). At this time, the updated security code and password are encrypted and transmitted, and after relaying the updated security code and password to the server side, command data for commanding deletion may be transmitted together.

If it is determined that the user input password matches through step ⑤, the security reinforced door lock 100 unlocks the door lock. When the door lock is unlocked by the password input, it is determined immediately or whether the conditions of FIGS. 4 and 5 are satisfied, and the password use function is temporarily stopped. Thereafter, after determining the unlocking of the door lock by the security code according to ST260 of FIG. 3, the previous password usage history along with the security code and password updated in step 7 are transmitted to the user portable terminal 200 according to step ST270.

Following step 7, the user portable terminal 200 relays the updated security code and password to the security management server 500 (step 8). At this time, the user's portable terminal 200 relays the updated security code and password to the security management server 500 by the command of the security reinforced door lock 100 or by the door lock management app's own function. It can be deleted from the temporary storage memory.

The security management server 500 updates security history such as a security code/password usage history together with the security code and password received from the user's portable terminal 200 (step ⑨). The security management server 500 issues the latest security code stored in the security code management database 510 when the next security code issuance request occurs, and the password management database 520 through user authentication accessed through the web. It guides you to the latest saved password.

8 to 13 are diagrams showing an execution example of a door lock management app installed in a user's portable terminal in the present invention, and show an example in which a user input window and a selection button are displayed by a touch user interface (TUI). With reference to these drawings, in the door security management system according to the present invention, opening and closing of a door lock, accessing and sharing passwords, guest management, setting of a door lock function, etc. will be described centering on a user's portable terminal.

For example, the user ID is the mobile phone number of the user registered by the door lock device. The password input window 255 is a window for inputting a password set by a user or through a door lock device. The automatic login check item 257 is an input item for setting by toggling automatic login and manual login according to a user's input.

In the present invention, users are divided into administrators and guests according to their authority. The administrator has the authority to request issuance of a security code and password for the security reinforced door lock 100, and permit issuance of a security code to a guest. The guest can use the restricted security code, and the guest's authority to use the security code is adjusted by the administrator. The initial registration procedure is different for the administrator and the guest, and it is preferable that the administrator registers using the security-enhanced door lock 100, and the guest registers with the administrator's permission.

The administrator logs in by entering the administrator login input button 261, and uses the app through authentication of the security management server 500. The guest logs in by entering the guest login input button 263, and uses the app with limited functions set by the administrator. In the present invention, "administrator portable terminal" means a user portable terminal authenticated through administrator login, and "guest portable terminal" means a user portable terminal authenticated through guest login.

After user authentication, the door lock opening app page as shown in FIG. 9 may be output. At the top of the door lock open app page, a menu button 265 that moves to a menu item or executes a pop-down menu, a door lock name display window 269 that displays the name of the door lock to be controlled, and a door lock to be controlled can be added. A door lock add button 267 is disposed.

The administrator may perform access management and guest management for a plurality of security-enhanced door locks 200, and each security-enhanced door lock 200 is assigned a unique name such as'door lock 23'.

Referring to FIG. 9, a door lock open selection button 271 is disposed in the center of the door lock open app page. As shown, the door lock open selection button 271 is intuitively displayed as an icon indicating door lock opening. When the door lock open selection button 271 is input by the user, the door lock management app transmits a security code issuance request signal to the security management server 500 as in step ① of FIG. 7. And the door lock will be unlocked as the procedure of step ② to step ④ proceeds. Thereafter, the procedure of step ⑥ to step ⑨ proceeds, and the security management server 500 relays the updated security code to update the security code management database 510, and records the new security code use history (and password use history). It will update the security history management database.

Meanwhile, the door lock open selection button 271 is also displayed on the guest portable terminal authorized by the administrator. However, the access record confirmation button 273, the password view button 275, the device setting button 277, the control target door lock movement slide 279, the emergency call button 281, etc. illustrated in FIG. 9 are only used in the administrator's mobile terminal. It is preferably displayed.

Referring to FIG. 9, when an access record confirmation button 273 is input through an administrator's mobile terminal, the door lock management app accesses the security management server 500 to view the security history management database 530. Then, by switching the app page, the security code usage history information and password usage history information for'door lock 23' are displayed on the screen.

When the password view button 275 is input, the door lock management app switches to the password view app page illustrated in FIGS. 10 and 11, and when the device setting button 277 is input, the door lock setting app page illustrated in FIGS. 12 and 13 Switch to

The control target door lock moving slide 279 is an input means for switching to a door lock opening app page for another security-enhanced door lock 100. For example, when the user inputs the control object door lock moving slide 279 in a right-handed way in the administrator's portable terminal, the door lock opening app page for'door lock 24' is switched. The door lock opening app page for'door lock 24' will be arranged in the same structure as in FIG. 9.

The emergency call button 281 is a button for connecting a call to a predefined contact. For example, when the user presses the emergency call button 281, a call connection is attempted to a pre-set phone number, such as a phone number, 119, or 112 of the Women's Safety Center. Alternatively, as described with reference to FIG. 6, a text message notifying the emergency situation stored in advance may be transmitted to the National Police Agency server 700.

10 and 11 are diagrams illustrating an example in which a password browsing app page is displayed on a screen by a door lock management app in the present invention. Referring to FIG. 10, the password browsing app page sequentially displays a plurality of passwords issued from the security management server 500. For example, if three different passwords are updated when the security code and password are updated from the security-enhanced door lock 200 as described above, the security management server 500 through the relay of the user's portable terminal 200 Is in the state of updating three passwords. The first password display window 291, the second password display window 293, and the third password display window 295 display different passwords, but display them by concealing them with masking characters such as'*'. A password view button 297 and a password sharing button 299 are disposed on the right side of each password display window.

In the example of FIG. 10, when a user inputs a password view button 297 for any one password, the password is displayed while the masking character of the password is removed as shown in FIG. 11. The user may directly input the displayed password to unlock the security-enhanced door lock 100. Alternatively, the user may be able to inform others of the displayed password. At this time, the door lock management app performs short-range wireless communication with the security-enhanced door lock 100, and a predetermined usage time (about 5 to 10 minutes) for the third password '391245' shown by the user as in FIG. After this, it is possible to transmit command data that commands the password to be revoked. That is, by setting a temporary use time for the password once exposed, the security against the exposure of the password can be strengthened.

In the example of FIG. 10, when the user inputs the password sharing button 299 for any one password, the door lock management app may transmit the corresponding password to the mobile terminal of the phone number input by the user or preset in advance. For example, when the password sharing button 299 is input, the app page is switched or a pop-up window is displayed, and a phone number to receive the password may be entered in the converted app page or pop-up window. At this time, the password is concealed and displayed to the user with a masking character, but the entire password may be displayed to others who share the password. Even in the case of password sharing, the door lock management app may transmit a usage time limit command to the security-enhanced door lock 100 side.
