Description

Security enhancement door lock and access door security management system using same

Technical Field

The present invention relates to a security enhanced door lock which improves user convenience and enhances security by providing a double unlocking function of a security code stored in a user portable terminal and a password input by a user, and a door access security management system which easily manages an person who accesses a door and performs security at a high level by using a door lock installed in a plurality of facilities, which is commonly used for a door lock including a door lock for a single female family.

Background

Generally, a door lock is a device installed in an access door to lock/unlock opening and closing of the access door. The general door lock performs locking and unlocking operations by inputting a password or reading biological information of a user.

The door lock in the password input mode is low in cost, is convenient for informing other people (such as friends, landlord, couriers, meter readers and the like), and is easy to leak through various ways. The way of reading the user biometric information is expensive, and unregistered persons cannot enter and exit, so that the problem of fundamentally preventing the entrance and exit of other persons except for the authentication of family members is caused. As another method, there is a method of opening and closing a door lock by an electronic key or an electronic tag, but the electronic key or the electronic tag is easily stolen or unauthorized copying is easily disabled.

Based on 2017, the number of korean single-woman families is over 280, and it is expected that over 380 will occur in 2045. Also, according to 2016' survey at the Korean statistic society, 46% of women in one-body female families answered that they felt uneasy about social security, and 37% of women classified the crime as a cause of uneasiness. According to the data of the korean criminal policy research institute, the possibility that a single female family suffers from illegal invasion is 11.2 times higher than the same male family. In addition, according to the korean police hall, 7 ten thousand 1868 crimes related to illegal entry occurred in total from 2014 to 2017, 1310 crimes occurred in total from illegal entry sex crimes in the last 4 years, and 99.8% of victims were males. In order to constitute family members of a family of single women, a door lock device that is convenient to use while enhancing security is required.

On the other hand, facilities such as relays, ground electrical facilities, street lamp distribution boxes, traffic signal controllers, etc. installed on the ground are used for management by various personnel such as police, manufacturer managers, managers of maintenance and repair cooperation companies, local government managers, and technicians. In these facilities, a door lock is installed to be opened and closed only by an allowed user. Door locks, which are often used by multiple people, are installed in a manner unlocked by a combination, but the fixed combination is easily leaked. The electronic tag, the physical key, and the like are at risk of being lost, and it is difficult to manage the person who enters and exits the facility. Therefore, a high security level is also required for the door lock of facilities and the like used by a plurality of users, and a new entry and exit management system which is easy to manage is required.

Korean granted patent No. 10-1208744 proposes an intelligent security door lock. In the same conventional document, when an electronic key transmitting an authenticated Identifier (ID) approaches a predetermined distance, a confirmation button attached to a door lock is input, and the door lock is controlled to be unlocked. However, as described above, the electronic key is easily lost, and the risk of unauthorized duplication of the identification included in the electronic key is high. In addition, when the user loses the electronic key, the user cannot unlock the door lock, and the door lock needs to be forcibly unlocked through a special program, so that the problem of long time consumption is caused in the process.

Detailed Description

Additional objects, features and advantages of the present invention will become more apparent in view of the following description and accompanying drawings.

The present invention may be modified in various ways and may have various embodiments before the present invention is explained in detail, and the examples described below and shown in the drawings are not intended to limit the present invention to specific embodiments, but should be understood to include all modifications, equivalents and alternatives included in the spirit and technical scope of the present invention.

When a component is referred to as being "connected" or "in contact with" another component, it can be directly connected or in contact with the other component, but it is also understood that other components may be present therebetween. In contrast, when an element is referred to as being "directly connected" or "directly contacting" another element, it is understood that no other element is present therebetween.

The terms used in the present specification are used only for describing specific embodiments, and are not intended to limit the present invention. Reference to a singular expression includes a plural expression unless the context clearly dictates otherwise. In the present specification, the terms "including" or "having" and the like are used to designate the presence of the features, numerals, steps, actions, components, parts, or combinations thereof described in the specification, and do not exclude the presence or addition of one or more other features, numerals, steps, actions, components, parts, or combinations thereof in advance.

The terms "… section", "… unit", "… module", and the like described in the specification refer to a unit that processes at least one function or operation, and may be realized by hardware, software, or a combination of hardware and software.

In the description with reference to the drawings, the same reference numerals are given to the same members regardless of the reference numerals, and thus redundant description is omitted. In the description of the present invention, if it is judged that the description of the related known art makes the present invention unclear, a detailed description thereof will be omitted.

In addition, throughout this specification, when a certain step is "on" or "before" another step, this includes not only a case where the certain step and the another step have a direct time-series relationship but also a case where an indirect time-series may reverse the time-series order in the order of the two steps (such as a mixed step after each step), and both have the same scope of rights.

Referring to fig. 1, the security-enhanced door lock of the present invention is composed of a keypad 110 and a handle 120 exposed to the outside of a door lock device 100, a locking/unlocking unit 130 provided inside the door lock device 100, a warning part 140, a storage unit 150, a short-distance communication module 160, a security code reading part 170, a security code/password updating part 180, and a locking/unlocking control part 190.

A keypad 110 provided with a plurality of numeric keys for inputting a password and a handle 120 for operating opening and closing of an entry/exit door are provided on the front surface of the door lock device 100. The keypad 110 may be composed of a physical number keypad, Touch keys, a Touch screen displaying numerical key icons supporting a Touch User Interface (TUI), and the like. In the same manner as in the case of a normal door lock, a voice signal for notifying the unlock state is output at the moment when the door lock is unlocked by the lock/unlock control section 190, and in this case, the user can operate the handle 120 to open the door while releasing the operation lock state of the handle 120.

The locking and unlocking unit 130 is a device for locking or unlocking an access door. For example, a solenoid or a motor is provided inside the door lock device 100, and a door catch attached to the access door is moved forward or backward to be inserted into or retracted from a door catch groove formed in a door frame, thereby locking or unlocking the access door.

The warning unit 140 may be a buzzer or a speaker for emitting a warning sound, or may be a warning lamp for visually warning, a Light Emitting Diode (LED), or the like. When the lock/unlock control unit 190 determines that the security code does not match or the password does not match, the warning unit 140 outputs a warning sound or turns on a warning lamp.

The memory unit 150 includes: a password storage section 152 for storing a password designated by the user; and a security code storage unit 154 for storing a security code updated by a security code/password updating unit 180 described later. The storage unit 150 may be formed of a flash memory or the like.

The short-range communication module 160 is a unit for communicating with the user portable terminal 200 through a Wireless Local Area Network (Wireless short-range communication Network). The short-range communication module 160 may be formed of modules such as a Radio Frequency IDentification (RFID), a Bluetooth (Bluetooth), a wireless communication technology (Wi-Fi), a Zigbee protocol (Zigbee), and the like.

The security code reading part 170 is a unit that reads a security code when the user portable terminal 200 comes within a communication radius of the short-range communication module 160.

The security code/password updating unit 180 updates the security code and the password only when the lock/unlock control unit 190 determines that the security codes match and switches the access door from the locked state to the unlocked state. When the locking/unlocking control unit 190 determines that the password is identical and unlocks the access door, neither the security code nor the password is updated. The security code/password updating part 180 transmits the updated security code and password to the user portable terminal 200. The updated security code is stored in the security code storage section 154, and the updated password is stored in the password storage section 152.

The security code is electronically readable data and is encrypted key information. A password is a string of numbers or data representing a string of numbers. For example, the new password updated by the security code/password updating section 180 is obtained by encrypting data representing a series of numbers.

In the invention, the security code is updated after being used once, and is disposable. The main body of the updated security code is a door lock device that is not directly connected to the network, and is transmitted to the security management server 500 through the relay of the user portable terminal 200. This provides the following advantages: the security code can be managed at a high security level, the security code can be prevented from leaking through a network, and the security code can be easily managed.

In the present invention, the password has a temporality to be temporarily used until the security code is updated. The password is used when the user portable terminal 200 is not present or when the user allows others (hereinafter, referred to as "visitors") to enter and exit. A plurality of passwords can be used, and the passwords used once are discarded, so that even if the passwords are leaked, illegal invasion can be prevented.

The security code/password updating section 180 encrypts and transmits the updated security code and password to the user portable terminal 200. Also, the user portable terminal 200 may be programmed not to be autonomously stored or deleted in a temporary memory when relaying the updated security code and password to the security management server 500. Alternatively, the security code/password updating unit 180 may include command data to be deleted in the user portable terminal 200 after relaying the updated security code and password to the remote security management server 500. Accordingly, the security code or password can be prevented from being leaked by hacking of the user portable terminal 200. Further, the password is updated at the same time as the security code is updated (even if the password is not used), and the password is provided with temporality, thereby preventing as much as possible the unauthorized entry due to the leakage of the password.

The lock-unlock control section 190 is a unit that controls the operation of the lock-unlock unit 130. The lock/unlock control unit 190 determines whether or not the security code read by the security code reading unit 170 matches the security code stored in the security code storage unit 154, and controls the lock/unlock unit 130 to switch from the locked state to the unlocked state. For example, when the user runs the door lock management application on the user portable terminal 200, a new security code is received from the security management server 500 described later, and the security code reading unit 170 may read the security code from the user portable terminal 200 to determine whether the security codes match.

Alternatively, the lock/unlock control unit 190 determines whether or not the password input by the user matches the password stored in the password storage unit 152, and controls the lock/unlock unit 130 to switch from the locked state to the unlocked state. For example, in a state where the user loses or does not carry the user portable terminal 200, another portable terminal or another communication terminal such as a notebook computer can be used to access the security management server 500 described later, and the new password can be confirmed by user authentication. In addition, when the user directly inputs the password in a state where the touch panel of the keypad 110 of the security enhanced door lock 100 is activated after checking the password, the lock unlock control unit 190 may determine whether the password is identical.

If the security codes or passwords do not match, the lock unlock control unit 190 activates the warning unit 140.

The lock/unlock control unit 190 determines whether or not the passwords match to unlock the lock/unlock unit 130, and then determines a predetermined condition to temporarily stop the password use function. That is, after the password is used and the predetermined condition is satisfied, the locking and unlocking unit 130 is operated only by determining whether or not the security codes coincide.

After the lock/unlock unit 130 is unlocked by using the security code, the password using function is activated again after a new security code and password are generated in the security code/password updating section 180. Therefore, the use of the password can be restricted to make it temporary.

When updating the password, the security code/password updating section 180 may generate a plurality of different passwords. For example, if a 6-digit password is used, two passwords "123456" and "345678" are generated. After updating the password, the lock/unlock control unit 190 performs control such that: for any one password (e.g., "123456"), the corresponding password is discarded after the unlocking operation of the lock unlocking unit 130 is performed, and the door lock is unlocked only for the remaining passwords (e.g., "345678"). That is, the used password is discarded to prevent the same password from being leaked and reused.

For example, the owner or manager may inform the maintenance service personnel of the password "123456" to allow access thereto, and the courier may be informed of the password "345678" to allow access thereto. However, by discarding the used password, the same password is prevented from being entered again, and thus crimes caused by password leakage can be prevented.

As another example, the lock/unlock control unit 190 may set a predetermined use time for any one of the passwords (for example, "123456"). For example, if the use time of the password "123456" issued to the maintenance service person is set to 5 minutes, the maintenance service person can freely enter and exit the house or facility in which the door lock of the present invention is installed within 5 minutes. However, if the usage time is exceeded, the issued password cannot be reused after the allowable time by discarding the corresponding password, and thus illegal entry by the same password can be prevented.

In the security enhanced door lock of the present invention, the door lock apparatus is not directly coupled with a network or a mobile communication network. The security-enhanced door lock is coupled with the user portable terminal 200 only through short-range wireless communication. The security enhanced door lock directly updates the security code and the password (one or a plurality of different passwords), and transmits the updated security code and password to the remote management server 500 through the relay of the user mobile terminal 200. Therefore, the security code and the password can be prevented from leaking through the network.

The security-enhanced door lock of the present invention has the advantage of having a double unlocking function of a security code and a password, in that it enhances security while providing user convenience. The user can freely enter and exit by using the security code stored in the portable terminal of the user. Alternatively, someone else may be informed of the temporarily provided password to allow restricted access by authorized users.

The advantages of the security enhanced door lock of the present invention mentioned, as well as the advantages and specific embodiments of the access door management system using the security enhanced door lock, are specifically described with reference to fig. 2 to 13.

Fig. 2 is a flowchart showing an example of a door lock operation using a security code in the present invention, and fig. 3 is a flowchart showing an example of a door lock operation using a password in the present invention. Hereinafter, an operation method of the security enhanced door lock according to the present invention will be described with reference to fig. 2 and 3.

Referring to fig. 2, the lock/unlock control section 190 determines whether or not the user portable terminal 200 is within the wireless communication radius of the short-range communication module 160 (step ST 110). For example, when the user operates the user portable terminal 200 to run a dedicated application (App), the short-range communication module 160 may be activated. As another example, the short-range communication module 160 may also be activated when the user portable terminal 200 is detected.

After that, the security code reading section 170 reads the security code from the user portable terminal 200 (step ST 120). Then, it is determined whether or not the read security code matches the security code already stored in the security code storage unit 154 (step ST 130). If the two do not match, the warning unit 140 is activated as described above (step ST 140).

If the security code is determined to match at step ST130, the door lock is unlocked (step ST 150). In this case, the unlocked state of the door lock can be output as a buzzer or other voice signal.

Then, as described above, the security code/password updating unit 180 updates the security code and the password, and stores the updated security code and password in the security code storage unit 154 and the password storage unit 152, respectively (step ST 160). The updated security code and password are encrypted and transmitted to the user portable terminal 200 (step ST 170).

Among them, it is important to update the security code and the password at the door lock itself and transmit the updated security code and password only through the wireless short-distance communication network 300. If the door lock directly transmits the security code to a remote management server through a network, the security code may be leaked through a public network. However, the security enhanced door lock of the present invention updates the security code and the password by itself whenever the security code is used, and the user portable terminal 200 relays only the updated security code and password to the remote security management server 500 as in the below-described entry and exit security management system, and does not retain the updated security code and password by itself, and does not retain the updated security code and password in the user portable terminal while preventing the updated security code and password from leaking through the network, thereby greatly enhancing security.

Also, another important point is that even if only the security code is used, the password can be updated at the same time as the security code is updated. As described above, when the security code is used, the security code and the password are updated at the same time at the door lock itself, whereby the risk of exposure due to long-term storage without updating the unused password can be reduced.

Referring to fig. 3, lock/unlock control unit 190 determines whether or not a password is input via keypad 110 (step ST 210). When the password is input, it is determined in the next step whether or not the input password matches the password stored in the password storage unit 152 (step ST 220).

If the passwords do not match, it is determined whether the number of consecutive passwords that do not match reaches a predetermined number (e.g., 5) (step ST 230). If it is determined in step ST230 that "Yes", the warning unit 140 is activated (step ST 240).

If it is determined in step ST220 that the password matches, the door lock is unlocked (step ST 250). In this case, the unlocked state of the door lock can be output as a buzzer or other voice signal.

When the door lock is unlocked by the password, the lock/unlock control unit 190 determines a predetermined condition to temporarily stop the password use function. That is, the door lock cannot be unlocked by inputting a password thereafter. A specific example of discarding and temporarily stopping a used password will be described below with reference to fig. 4 and 5.

Thereafter, it is judged whether or not the door lock is unlocked by using the security code (step ST 260). The process of unlocking the door lock by using the security code is the same as that described with reference to fig. 2.

If the door lock is unlocked by using the security code, step ST160 and step ST170 of fig. 2 are performed, and when the security code and the password are updated and transmitted to the user portable terminal 200, the password is transmitted including the previous password use history (step ST 270). Therefore, as described later, the use history of the password can be stored and managed at the remote management server.

Fig. 4 is a flowchart showing an example of using and discarding a plurality of passwords in the present invention, and fig. 5 is a flowchart showing an example of discarding passwords after setting the use time in the present invention.

As described above, the security code/password updating section 180 may generate one or more passwords while updating the security code and the password. As illustrated in fig. 4, the lock/unlock control unit 190 may use the plurality of passwords only once or may limit the number of times of use. As another example, as illustrated in fig. 5, the lock/unlock control section 190 may restrict the use time of one password.

First, referring to fig. 4, the lock/unlock control unit 190 may discard the used password after step ST250 of fig. 3 is completed (step ST 410). Then, it is judged whether or not all the passwords are discarded (step ST 420). If there is a remaining password, step ST210 is performed. If the user uses the security code after using any one of the passwords, step ST260 may be performed even after step ST 420.

For example, if two passwords "123456" and "345678" are newly generated and the password "123456" is input in step ST210 of fig. 3, the password "123456" is discarded in step ST410 after the door lock is unlocked in step ST 250. Since there is a remaining password of "345678", it is possible to proceed to step ST210 and wait whether or not a new password is input. If the security code is used, the procedure goes to step ST260 and step ST270 to update the security code and the password.

Assume that both passwords "123456" and "345678" are used before updating the security code and password. Since the password "345678" is discarded in step ST410 and the condition in step ST420 is satisfied, the lock/unlock control unit 190 performs step ST430 to temporarily stop the password use function (step ST 430).

Thereafter, 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 to reactivate the door lock unlock function with the password.

Thereafter, referring to fig. 5, the lock/unlock control unit 190 may set the reuse time of the used password after step ST250 of fig. 3 is finished (step ST 510). The reuse time can be set by a user's specification. For example, the reuse time of the password may be set by a user inputting a button inside the door lock to input a time of 5 minutes to 10 minutes. Alternatively, although not shown, the number of times of reuse of the password may be set.

In the next step, it is judged whether or not the reuse time of the corresponding password is exceeded (step ST 520). This step may also be replaced with a step of determining whether the number of reuse times of the corresponding password exceeds the set number of times. Before the reuse time is exceeded (or before the number of times of reuse is exceeded), it may return to step ST210 to reuse the corresponding password. In the process of determining whether the reuse time is exceeded, if the user uses the security code, step ST260 may be further performed.

If it is determined in step ST520 that the reuse time for any password exceeds or the number of times of reuse is cleared, the corresponding password is discarded (step ST 530). Then, step ST540 is performed to determine whether all the passwords are discarded. If there is a remaining password, step ST210 is performed. If the user uses the security code even in the middle of any step, step ST260 may be performed.

If it is determined in step ST540 that one or more passwords have been discarded, lock unlocking control unit 190 proceeds to step ST550 to temporarily stop the password use function (step ST 550).

Thereafter, 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, the door lock unlocking function by the password may be activated again by issuing a new password(s).

Fig. 6 is a block diagram illustrating an access door security management system of the present invention. Hereinafter, an entrance and exit door security management system according to the present invention will be described with reference to fig. 6.

The access door security management system of the present invention includes a security enhanced door lock 100, a user portable terminal 200, and a security management server 500.

The security enhanced door lock 100 is the same as described with reference to fig. 1 to 5.

The user portable terminal 200 is a terminal which communicates with the security enhanced door lock 100 through the wireless short-range communication network 300 and communicates with the security management server 500 through the wide area mobile communication network 400. The user portable terminal 200 may be a dedicated terminal, preferably a smart phone, for implementing the entry and exit door security management system of the present invention. A dedicated application for managing the security code may be installed in the user 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 constituted by a module of radio frequency identification, bluetooth, wireless communication technology, zigbee protocol, or the like. Also, 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 that performs mobile communication in a known communication band such as 3G, 4G, or 5G, or a module that performs mobile communication in an unknown next-generation communication band. For example, the Mobile communication module 230 is a wireless communication module that transmits and receives signals to and from a base station, a terminal, an external server, or at least one wireless communication network constructed according to a Global System for Mobile communication (GSM), Code Division Multiple Access (CDMA), Code Division multiple Access 2000(CDMA2000, Code Division multiple Access 2000), Enhanced Voice Data Optimized or Enhanced Voice Data Only (EVDO), Wideband Code Division multiple Access (WCDMA, Wideband CDMA), High Speed Downlink Packet Access (HSDPA, High Speed Uplink Packet Access), High Speed Uplink Packet Access (HSUPA, High Speed Uplink Packet Access), Long Term Evolution (LTE, Long Term Evolution), Long Term Evolution-Advanced (LTE-a, Long Term Evolution-Advanced), and the like.

The user portable terminal 200 includes a storage unit for storing the security code and the password issued from the security management server 500. Generally, a smartphone includes the listed short-range communication module, mobile communication module, memory, and the like. And, the user is already paying for mobile communication and wireless internet. That is, the smartphone installs and runs a door lock management application described later with reference to fig. 8 to 13, and has an optimal environment for implementing the entry and exit door security management system of the present invention. Therefore, the security code/password issuance request, relay, unlocking of the door lock, user management, door lock function setting, and the like described in the present invention are easily realized only by providing a door lock management application to a portable terminal used by a user.

In the present invention, the user portable terminal 200 relays the updated security code and password to the remote security management server 500 only in the security enhanced door lock 100, and does not store it by itself. The door lock management application installed in the user portable terminal 200 may be programmed to transmit information including the security code and password updated in step ST170 of fig. 2 and the usage history thereof from the security enhanced door lock 100 to the security management server 500, and then delete the updated security code and password by itself.

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 according to the security enhanced door lock 100; a password management database 520 for storing and managing passwords according to the security-enhanced door lock 100; and a security history management database 530 for storing and managing the release history and the use history of the security codes and the password according to the security enhanced door lock 100. The security code management database 510, the password management database 520, and the security history management database 530 may be implemented as a database server installed in a storage space of the security management server 500 or separately managed.

In the present invention, the security management server 500 does not directly generate the security code and the password. Only the security code and the password relayed through the user portable terminal 200 (the security code and the password updated by the security enhanced door lock itself) are stored and managed.

In the case where 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 performing an authentication process.

For example, if the user runs the door lock management application on the user portable terminal 200, an authentication request is automatically transmitted to the security management server 500. The security management server 500 may issue the security code by recognizing a phone number or a Mac address (Mac address) of the user portable terminal 200.

Also, in the case where the user connects to the network using a computer terminal capable of surfing the internet, the security management server 500 confirms the account and password of the user or confirms the public certificate to provide the user with the latest password stored in the password management database 520.

Referring to fig. 6, the entry and exit security management system of the present invention may further include a police hall server 700, a guardian portable terminal 800, or other servers or terminals, etc. coupled with the security management server 500 or the user portable terminal 200 through the wide area mobile communication network 600.

In case that the user inputs a specific key, a key combination, or an emergency notification icon configured on the application execution screen, the door lock management application installed in the user portable terminal 200 may transmit an emergency message to the security management server 500, the police hall server 700, or the guardian portable terminal 800. For example, in the case where a member of a single female family waits for opening an entry/exit door or an annoyance approaches the entry/exit door, an emergency message may be transmitted to the security management server 500 or a pre-designated server or terminal.

And, the user portable terminal 200 can transmit an emergency message to the security-enhanced door lock 100 through the wireless short-range communication network 300. In this case, the security-enhanced door lock 100 stops the door lock unlocking function by the security code and converts the function into unlocking the door lock only by inputting the password. Therefore, the user portable terminal 200 can be prevented from being stolen and a thief can be prevented from unlocking the door lock without permission.

Fig. 7 is a data flow diagram illustrating an access door security management method of the present invention. Hereinafter, the flow of data between the components constituting the access door security management system of the present invention will be described with reference to fig. 7.

When the user runs the door lock management application on the user portable terminal 200 to open the entrance/exit door, a security code issuance request signal is transmitted from the user portable terminal 200 to the security management server 500 (step (r)). The security management server 500 performs an authentication process for the user portable terminal 200 to issue a security code (step two).

When the user inputs an open icon on the application screen after the user's portable terminal 200 approaches within the short-distance wireless radius of the security enhanced door lock 100 or when the lock/unlock control unit 190 is automatically activated in the security enhanced door lock 100, the security enhanced door lock 100 reads the security code stored in the user's portable terminal 200 (step c). The security-enhanced door lock 100 determines whether the read security code is identical to the stored security code (step (r)).

In the case where the user directly inputs the password through the keypad 110 provided at the security-enhanced door lock 100 instead of the steps (r) to (r), it is also possible to judge whether the password input by the user is identical to the stored password (step (c)).

When the security codes are determined to be consistent through the steps one to four, the door lock is unlocked, the security codes and the passwords are updated and then are stored in the security code storage part 154 and the password storage part 152, respectively (step (c)).

Then, the security enhanced door lock 100 transmits the updated security code and password to the user portable terminal 200 (step c). In this case, the updated security code and password are transmitted in an encrypted manner, and command data that instructs the server side to delete the updated security code and password can also be transmitted.

And if the password input by the user is judged to be consistent through the fifth step, the security-enhanced door lock 100 unlocks the door lock. When the door lock is unlocked by inputting the password, the password using function is temporarily stopped immediately, or the password using function is temporarily stopped by determining whether the conditions of fig. 4 and 5 are satisfied. After that, after it is judged that the door lock is unlocked by the security code according to step ST260 of fig. 3, the security code and the password updated in step (c) and the previous password use history are transmitted to the user portable terminal 200 according to step ST 270.

After step (c), the user portable terminal 200 relays the updated security code and password to the security management server 500 (step (b)). In this case, the user portable terminal 200 may delete the updated security code and password from the internal temporary memory after relaying the updated security code and password to the security management server 500 by the command of the security enhanced door lock 100 or the self-function of the door lock management application.

The security management server 500 updates the security history such as the security code and password received from the user portable terminal 200 and the history of use of the security code/password (step nini). In the case where the next security code issuance request occurs, the security management server 500 issues the latest security code stored in the security code management database 510, authenticates the user who accesses through the network, and provides the latest password stored in the password management database 520.

Fig. 8 to 13 are views showing an example of the operation of the door lock management application installed in the user portable terminal in the present invention, and show an example of displaying a user input window, a selection button, and the like on a touch user interface. Hereinafter, the opening and closing of the door lock, the password checking and sharing, the visitor management, the door lock function setting, and the like will be described centering on the user portable terminal in the entry and exit security management system of the present invention with reference to the drawings.

Fig. 8 is a view illustrating a user authentication screen of the door lock management application installed in the user portable terminal in the present invention, illustrating an operation initial screen of the door lock management application. Referring to fig. 8, a door lock application flag 251 is displayed at the upper end of the center of the user authentication screen, and the door lock application flag 251 is an visualized flag for making the user recognize the operation of the door lock management application. An account input window 253, a password input window 255, an automatic login check item 257, a manager login input button 261, and a guest login input button 263 are displayed below the door lock application flag 251.

The account input window 253 is a window in which a user initially inputs or inputs an account granted by the user's authority. For example, the user account is a mobile phone number of a user registered through the door lock device. The password input window 255 is a window for inputting a password set by a user or set through a door-lock device. The automatic login check item 257 is an input item set by switching between automatic login and manual login by the input of the user.

In the invention, users are divided into managers and visitors according to the authority. The manager has a right to request issuance of a security code and password for the security enhanced door lock 100 and allow issuance of a security code for visitors, etc. The visitor can use the limited security code, and the security code using permission of the visitor is adjusted by the manager. The initial registration steps of the manager and the visitor are different from each other, and preferably, the manager registers with the security-enhanced door lock 100 and the visitor registers with the manager's permission.

The administrator logs in by inputting the administrator login input button 261 and uses the application by authentication of the security management server 500. The visitor logs in by inputting the visitor login input button 263 to use the application program through a limited function set by the administrator. In the present invention, the "administrator portable terminal" refers to a user portable terminal authenticated by a manager login, and the "guest portable terminal" refers to a user portable terminal authenticated by a guest login.

Fig. 9 is a diagram showing an example of performing door lock unlocking by the door lock management application in the present invention, and is a diagram showing an operation example in the administrator portable terminal.

After the user authentication is performed, a door lock unlock web page as in fig. 9 may be output. The upper end of the door lock unlocking webpage is provided with: a menu button 265 for moving to a menu item or executing a pop-up menu; a door lock name display window 269 for displaying the name of the control target door lock; and a door lock addition button 267 to which a control target door lock is added.

The manager may perform access management and visitor management for a plurality of security-enhanced door locks 100, and assign a unique name such as "door lock 23" to each security-enhanced door lock 100.

Referring to fig. 9, a door lock unlock selection button 271 is disposed at the center of the door lock unlock web page. As shown in the figure, a door lock unlock selection button 271 is displayed to visually display an icon of door lock unlock. As in step (r) of fig. 7, in the case where the user inputs the door lock unlock selection button 271, the door lock management application transmits a security code issuance request signal to the security management server 500. And, the door lock is unlocked by performing the steps from the second step to the fourth step. Thereafter, in steps sixteenth to ninth, the security management server 500 updates the security code management database 510 by receiving the relayed updated security code, and may update a new security code usage history (and password usage history) to the security history management database.

In addition, a door lock unlock selection button 271 may also be displayed on the visitor portable terminal allowed by the manager. It is preferable that the entry and exit record confirmation button 273, the password viewing button 275, the device setting button 277, the control object door lock movement slider 279, the emergency call button 281, and the like illustrated in fig. 9 are displayed only on the administrator portable terminal.

Referring to fig. 9, when the entry/exit record confirmation button 273 is input through the administrator portable terminal, the door lock management application accesses the security management server 500 to read the security history management database 530. Then, the application page is switched to output the security code use history information and the password use history information for the "door lock 23" on the screen.

When the password check button 275 is input, the door lock management application is switched to the password check application page illustrated in fig. 10 and 11, and when the device setting button 277 is input, the door lock management application is switched to the door lock setting application page illustrated in fig. 12 and 13.

The control object door lock movement slider 279 is an input unit for switching to a door lock open application page for the other security enhanced door lock 100. For example, when the user inputs the control target door lock movement slider 279 by sliding the administrator portable terminal to the right side, the application page is switched to the door lock open application page for the "door lock 24". The door lock unlock application page for "door lock 24" is configured in the same structure as that of fig. 9.

The emergency call button 281 is a button for talking with a preset contact. For example, if the user inputs the emergency call button 281, a call with a phone number previously set, such as a phone number of a female security center, 119 or 112, is attempted. Alternatively, as described with reference to fig. 6, a text message informing of a previously stored emergency may also be transmitted to the police hall server 700.

Fig. 10 and 11 are diagrams showing an example of outputting a password checking application page through a screen of a door lock management application in the present invention. Referring to fig. 10, the password view application page sequentially displays a plurality of passwords received from the security management server 500. For example, when the security code and the password are updated from the security enhanced door lock 100 as described above, if 3 passwords different from each other are updated, the relay security management server 500 of the user portable terminal 200 is in a state of updating the 3 passwords. The first, second, and third

password display windows

291, 293, and 295 display a plurality of different passwords, but hide them with a mask character such as a "". A password view button 297 and a password share button 299 are provided on the right side of each password display window.

In the example of fig. 10, in the case where the user inputs the password view button 297 for any one password, as in fig. 11, the password is displayed while removing the mask text of the corresponding password. The user may unlock the security enhanced door lock 100 by directly entering the displayed password. Alternatively, the user may inform others of the displayed password. In this case, the door lock management application performs short-range wireless communication with the security enhanced door lock 100, and if the third password "391245" displayed to the user exceeds a prescribed use time (5 minutes to 10 minutes), as shown in fig. 11, it can transmit command data instructing to discard the corresponding password. That is, a temporary use time is set for a password that has been exposed once, whereby security against password exposure can be enhanced.

In the example of fig. 10, in the case where the user inputs the password sharing button 299 for any one password, the door lock management application may transmit the corresponding password to the portable terminal of the phone number designated in advance or input by the user. For example, when the password sharing button 299 is input, the application page is switched or a pop-up window appears, and a phone number to receive a password may be input to the switched application page or pop-up window. In this case, the user is hidden and displayed with the corresponding password by the masking text, but the entire password is displayed to the other person who receives the password sharing. When the password is shared, the door lock management application may transmit a use time limit command to the security enhanced door lock 100 side.

The search screen selection window 357 is a window for selecting a search screen (e.g., name, nickname, phone number, etc.), and the search word input window 359 is a window for inputting a search word. If "name" is selected in the search screening selection window 357 and "gold" is input in the search word input window 359, the door lock management application searches the list stored in the administrator portable terminal for the corresponding name. And, the search result is output in the visitor information display window 361. For example, the name and phone number of the searched visitor may be displayed in the visitor information display window 361. If the user inputs the invite button 363 after confirming the visitor through the visitor information display window 361, the searched visitor is listed in the lower participating visitor display window 365. If the delete button 367 disposed at the right side of each guest list is output, the corresponding guest is removed in the participating guest display window 365.

As described above, the visitors listed in the participating visitor display window 365 refer to visitors who are allowed to use the security code. That is, as illustrated in fig. 12, the manager may allow or prevent the use of the security code for multiple visitors in accordance with the security enhanced door lock 100.

Referring to fig. 13, in the case of inputting the function setting button 355 at the upper end of the screen, the corresponding button is displayed deepened or highlighted to activate the function setting application page.

The name of the security enhanced door lock 100 (door lock 23) as a control target is displayed on the door lock name display window 371, and a modifier button 373 is disposed on the right side thereof. In the case where the user inputs the modification button 373, the door lock management application switches to an application page that can modify the name of the door lock or activates a pop-up window.

The password management screen moving item 375 is an input unit for switching to a screen for managing a password, and the door lock deletion screen moving item 381 is an input unit for switching to a screen for removing a corresponding security enhanced door lock from a management object.

The manual permission switching slider 377 is an input item for whether or not to manually permit the selection ON (ON)/OFF (OFF) by the slide. If the user moves the manual permission switching slider 377 toward the left side, the manual permission state is turned off and set to a state in which the participating visitor automatically receives the security code as illustrated in fig. 12. If the user moves the manual permission switching slider 377 toward the right side, the manual permission state is turned on and switched to a state where all visitors receive the security code through the permission of the administrator.

The control switch slider 379 is an input item for selecting Open (ON)/close (OFF) by sliding for whether or not to control the security enhanced door lock. If the user moves the control switch slider 379 toward the left side, the control state is turned off and set to a state in which the participating visitor automatically receives the security code as illustrated in fig. 12. If the user moves the control switching slider 379 toward the right side, the control state is turned on and switched to a control state in which the release of the security code to all the visitors is stopped.
