[For public use message ]

Even if not described in the present invention, basic functions of the existing door lock (eg, automatic locking after the door is closed) may be included. The door lock for the present invention additionally has a display device (eg, liquid crystal), and outputs a message input by a user (a public PR message or a private message provided to an authorized user) to the display device. “Message” includes “text message (visual message)” and “voice message (audible message)”.

In the case of digital door locks, most of them basically have a method of authenticating by password (password). This is because it is inexpensive compared to biometric methods and has the advantage of not having a key. In the case of the password method, since a numeric keypad is usually provided, it can be used as a keypad for character input. The door lock in the present invention may additionally be configured with a biometric method such as an RF card method and a fingerprint as well as a password method.

Fig. 1A is a conceptual block diagram of a door lock equipped with a numeric keypad and a message input/output function is additionally provided, and Fig. 1B is a configuration diagram in this case. In Fig. 1b, a Korean keypad for Korean character input technology suggested in the applicant's prior application is presented, but it is obvious that any character input technology can be applied. In Fig. 1b, an example of simply displaying a "Public PR message" is given. Creating a message based on the input value is performed inside the door lock. In Figure 1a, the “sound output unit” outputs a warning sound or a guide sound, and may or may not be depending on the product. In addition, the “password input unit 13” and “message input unit 14” may be made on the same keypad, but when implemented in software, the message input mode and the password input mode will be different. It was expressed as having branch inputs 13 and 14.

Also, the display device (eg, liquid crystal) may not be able to display all messages due to its small size. To solve this problem, it is possible to show the message while sliding. For example, if only one line is displayed, the message is displayed as it slides from right to left. Even when multiple lines are displayed, it is possible to display the entire message while sliding from the bottom to the top.

In the past when general housing was generalized, there was a “nameplate”, but it can be expected that the message for opening the door lock of the present invention can provide softness in the hard era where only the number (apartment number) remains as the residential environment is converted to an apartment. . Even if it is a home or company that has nothing to use as a public message, “This is a security specialized company ㅇㅇㅇ Security area!!” You can even put the phrase "".

[For private use message ]

There may be cases where it is not simply a public message that is open to everyone. For example, “My dear son, I am late today. It is not possible to make a message such as “Let's take care of dinner on our own…” and make it publicly visible to everyone. This is because you are advertising an empty house to a thief. It should be visible only to certain authorized users. Therefore, it should be saved as a “private message” and only authorized users can view the message.

A typical way to view a message would be to enter a user ID and a password corresponding to the user ID to view. However, recently, a door lock system has emerged in which multiple passwords are designated and each user uses their own password. In this case, since the specific password itself serves as an ID (identifier) for a specific person, when a specific password is input, a specific message specified for the user can be output.

There may be various methods of storing a private message, but an example is as follows. The user enters the administrator mode with his/her password, selects the user to send the message from the list of users, and creates the desired message after selecting the user. Similarly, the process of outputting a message for private use can be performed by a process in which the user to whom the message is to be delivered is authorized (the corresponding password is input), and a process in which the message is output.

For example, for a mother's son's password (password) “1111” or “ㄱㄱㄱㄱ”, the above private message (“My dear son, I'm late today. Let's take care of dinner...”) is saved (text) After the procedure of saving as a message or audio), when the son returns home and enters the promised password (“1111” or “ㄱㄱㄱㄱ”), the message is output in the promised manner (printed on the display window of the door lock, text It is possible to process a private message by a procedure of converting and outputting or outputting a stored voice) to voice. Preferably, after the message is displayed, if the user takes some action (eg, pressing the “OK” button or the “Delete” button), the door lock is opened or the entire message is printed and after a certain period of time (eg 3 seconds). You can also have the door lock open.

In the keypad illustrated in FIG. 1A, "[1] button = [a] button", and scan codes (unique key values defined for each key) are the same. Therefore, whether the user enters “1111” consciously or “ㄱㄱㄱㄱ” consciously, the door lock recognizes the same, so the password is expressed as “1111” or “ㄱㄱㄱㄱ”. This is the same as inputting the Korean [ㅁ] key or the English [a] key when entering the password on the PC. Since the [1] ~ [0] number buttons are the same for all products, in the following, the numeric value is mainly displayed as a password.

[External interface module]

The present invention is not applicable only to a password-type door lock, and in the case of a door lock that does not have a keypad as an input device, an interface module 23 that is connected (wired or wirelessly connected) to a separate built-in input device or an external input device. ). In addition, even if the input device 23 is provided in the door lock, it is possible to input a desired message through an external input device (eg, mobile phone, PC) desired by the user.

Fig. 2a is a block diagram of a case through an external input device. When using an external input device instead of using an internal input device (e.g., the keypad of the door lock) provided in the door lock itself, only the scan code value (unique key value defined for each key) required for character generation in the external input device is used. It is possible to take over and generate a message from the door lock, or receive a message generated from an external input device and display its contents. The former is a case in which a message for an input value is generated at the door lock as shown in Fig. 1b, and the latter is a message generated by an external input device and the generated message is delivered to the door lock.

The interface 26 with the external input/output device 27 may be made through any means, including infrared communication, Bluetooth, wireless LAN (WiFi), wireless Internet (WiBro), wired Internet, wired telephone, etc. It can be achieved by the communication function of the mobile phone (eg CDMA, GSM method) and the function of short message transmission. Fig. 2b is a configuration diagram when a mobile phone or a similar terminal having a communication function of a mobile phone is applied as the external input/output device 27. Figure 2b shows an example of posting a public relations message for a company.

In the case of applying non-short-range wireless communication means such as infrared communication or Bluetooth (eg CDMA or similar technology such as GSM), there is an advantage of being able to control the door lock (eg message registration) from a remote location. In this case, the control program operating on the mobile phone in conjunction with the door lock will be implemented as a program on the wireless Internet platform of the mobile phone.

[Notify Promised User]

Additionally, a wired or wireless communication module 38 may be provided on the door lock. See Figure 3. For wired communication, you can think of general telephones, and for wireless communication, the communication function of mobile phones is typical. The difference between the wired or wireless interface modules 27 and 37 and the wired or wireless communication module 38 is as follows. The interface modules 27 and 37 are modules that allow control of the door lock through an external input/output device, and the communication module 38 can be viewed as a means of communication with an external device. In FIG. 3, the wired and/or wireless interface module 37 may be provided as in FIG. 2A or may not be provided as in FIG. 1A. When 37 as a mobile communication is provided, in reality, 38 as a mobile communication will be configured with 37, but is conceptually illustrated separately. Similarly, if (37) is provided as a wired communication (eg Internet), it will be configured with (38) as a wired communication in reality.

When the door lock is opened when the private message is first displayed, a message (text message or voice message) is sent to the mobile phone of the promised user (e.g., the user who entered the private message or the entire administrator), indicating that the message has been read. It is possible. For example, it informs the promised user that "the message was output to the son (user with the password "1111") at xx:xx:xx on xx/xx/2006. In all cases, if a specific user (son who uses the password “1111” or “ㄱㄱㄱㄱ” in the case) sends a text message when entering and exiting, if the son opens and closes the door lock 10 within 10 minutes, 10 texts within 10 minutes You will receive a message because it causes a huge waste of operating costs and becomes very annoying to the user who receives the message due to the spam message.

In the case of a private message, when a number of designated users are designated, when each user first reads the message (i.e., the door lock first outputs the message for a specific user), the message is notified to the administrator's mobile phone. I can.

That is, in addition to the above-described procedure, a procedure to check whether a private message was first output to the user to be viewed, and if the private message was first displayed, the fact (message output fact) is notified to the promised user. It includes additional procedures for doing so.

In addition, in the door lock with the external communication function 38 added to the door lock, if the mobile phone number of the user that is the target of the private message is registered in the user database (stored in the memory 32 of the door lock), the user's It is also possible to send the message to the mobile phone.

Furthermore, even if there is no private message, only when a specific user opens the door lock for the first time in a specific time period (eg 0 to 24 hours, 13:00 to 24 hours, or 06 to 12 hours), the promised user (eg the best). Administrator) can be notified (text message or voice message). Taking the example of a family, it has the effect of allowing a mother who is out to know when their children return home.

[User Management]

User management may be performed similarly to existing user management (user management in a device such as a PC). A simple example in connection with the present invention is as follows. In this case, it is assumed that a specific user is not recognized by ID and password, and the password itself also has a specific user authentication function.

First, it is assumed that the user of the registered password basically has the super administrator function. The super administrator can create multiple passwords (ie, users) and grant privileges (eg administrator rights or general user rights). Each user can enter his/her password and enter the management mode to change his/her password or enter a public or private message.

Here, whether a user designated as an administrator by the top administrator has the same authority as the top administrator (eg, password creation, that is, user creation, etc.) is a matter of operational policy, so it will not be discussed further. Also, whether to subdivide the user level or to allow the creation of a message for public use with general user authority is a detailed issue in the operation policy, so it is not mentioned any more.

First, when the super administrator enters the super administrator password and enters the management mode and searches the registered user list, the following contents stored in the memory of the door lock will be displayed. Of course, the process of entering the management mode may be performed by an input device of the door lock itself, or may be performed in conjunction with an external input device (eg, a mobile phone or a PC).

password User name authority (cellphone) 7777 or ㅅㅅㅅㅅ Chief Administrator

When creating a user, adding a user according to a predetermined procedure (eg, pressing the menu button and selecting Add Password from the created menu) will result in the following. The following is an example of modifying the top administrator information and adding users. The user name can be viewed as a nickname registered to make it easier to identify who the user of a specific password is, and the user's name or position can be registered. In reality, the top manager will be the security officer of the organization (company or home) or the person in charge of the security security company will be registered.

password User name authority (cellphone) 7777 or ㅅㅅㅅㅅ Security Officer Chief Administrator (010-7777-7777) 5555 or ㅁㅁㅁㅁ CEO manager (010-5555-5555) 3333 or ㄷㄷㄷㄷ employee Normal

As before, in a door lock that does not have a display device (eg, liquid crystal) and an input device, such a user-friendly interface (eg, input and display of user name) would not have been possible, but if a liquid crystal is provided as in the present invention, the above management Interface configuration is possible. When performed by an external input/output device, the output of the management details will also be displayed on the display device of the external input device (eg, a screen of a PC or a liquid crystal of a mobile phone) rather than the liquid crystal of the door lock. Of course, after the management details (eg, creation of a message for disclosure) are completed, the message for disclosure is displayed on the display device of the door lock, but the details of the management status should not be displayed on the display device of the door lock at a remote location with the user. In addition, contact numbers such as mobile phones are indicated in parentheses because they are unnecessary items when the communication module 38 is not added to the door lock itself.

When creating a public message (e.g. press the menu button and choose to create a public PR message), you can enter the public message creation screen, write the message, and save it. If you want to modify the information of a specific user, select a specific user and then go to “Edit information” to modify the information. Likewise, when creating a private message, select a target user (one or more) (eg select a check box for each user) and enter the “private message” creation menu (eg press the menu button and select create private message). Just do it.

What is important here is that if a general user (eg son) who uses the password “1111” or “ㄱㄱㄱㄱ” enters the management mode, it should not be able to see the password of others in the user list. That is, it is desirable to display a list of users (passwords) as in the following example. Whether the mobile phone number cannot be viewed with general user rights is also a matter of operation policy.

password User name authority (cellphone) **** Security Officer Chief Administrator (010-7777-7777) **** CEO manager (010-5555-5555) 3333 or ㄷㄷㄷㄷ employee Normal

In the case of a small company, log data of door lock opening may be used for employee time and attendance management. Of course, this is possible by connecting devices such as a PC through an external interface module of the door lock and dumping the door lock open log data.

In the case, for convenience, the password is expressed in 4 digits, but security can be strengthened by specifying the minimum number of digits in the password according to the security policy.

[Emergency contact]

When a voice call function is added to the communication module 38 on the door lock, an unauthorized visitor (i.e., a visitor who has not been given a password) can make an emergency contact (phone call) to the promised user (eg, the supervisor). can do. Of course, in this case, the mobile communication number assigned to the door lock and the phone number of the promised user (eg, the top administrator) are not exposed. This is meant to be able to cope with the person's absence without, for example, notifying the delivery driver of the mobile phone number of the baggage recipient in advance. In addition, it can be used in an emergency by registering the emergency contact phone number as the phone number of a security security company.

[Security anomaly notification]

When the communication module 38 is added to the door lock, when a security abnormality symptom (eg, password mismatch more than a certain number of times (eg 3 times)) occurs, to the promised user (eg, a top administrator or a security security company) A notification (text or voice) service is available.

Expressed as a procedure, it may consist of a procedure of counting password mismatches, a procedure of checking occurrences of mismatches more than a predetermined number of times, and a procedure of notifying a promised contact information by a promised means.

[Dual security, secondary password]

When the wired or wireless communication module 38 is added to the door lock, double security is possible by allowing the user to input a second password. In the example, if the password of the “president” (in this case, the primary password) “5555” is exposed, even a user who should not be authorized can open the door lock. However, according to the security policy (eg, the super administrator sets the second password to be applied), when entering “5555”, the registered president's mobile phone number “010-5555-5555” is used as the second password (eg, the second password specified by the administrator). The password or the random number generated by the door lock) is transmitted as a text message, and the second password must be re-entered within a certain period of time (eg, 30 seconds) to open the door lock.

When the secondary password is applied, the input of the primary password plays a role of identifying the user (not approval). Such user identification can not be performed only by the input of the primary password, but biometric recognition (eg fingerprint recognition). ), the user can be identified by RF card recognition. And it is possible to complete double security by sending a secondary password to the mobile phone registered to the user and requesting an input. In the above case where only the primary password was applied, if the RF card was used as user identification, the user database would be as follows.

RF card User name authority (cellphone) Card 1 Security Officer Chief Administrator (010-7777-7777) Card 2 CEO manager (010-5555-5555) Card 3 employee Normal

In summary, a process of recognizing a user (by inputting a primary password, biometrics, or RF card), a process of transmitting a secondary password to the registered user's mobile phone, and a process of receiving and confirming the transmitted secondary password. It is possible.

In this case, a person who intends to trespass cannot open the door lock by simply obtaining an available password (primary password), and since the password user's mobile phone must also be present, there is an effect of enhancing security.

However, since it may cause inconvenience to always enter the secondary password, according to the security policy, for example, if a specific user first succeeds in authentication with the secondary password for a certain period (eg a day), that period (eg. During the day), it can be operated so as not to ask for a second password. This security policy profile can also be specified by the top administrator.

To summarize the above case again, the process of recognizing the user (by input of the primary password, biometrics or RF card), the process of verifying whether authentication by the secondary password has been performed within a specified period, and if it is done, open the door lock. Otherwise, it is possible to transmit the secondary password to the mobile phone of the user, or to re-enter and confirm the transmitted secondary password.

Another example is to send a second password prompt (voice and/or text display) and if there is no input within a certain amount of time (eg 5 seconds), the second password can be sent to the user's mobile phone. According to the security policy, if the secondary password sent to the user is valid for a certain period of time (eg, one day or one week), the secondary password already known to the user can be reused during that period. This explains that it is possible to save the operation cost (eg, text message transmission cost) of the door lock while applying the secondary password.

To summarize the above case again, the process of recognizing the user (by inputting the primary password, biometrics or RF card), the process of requiring the input of the secondary password, and the process of requiring the input of the secondary password within a certain period of time, This is possible by transmitting the secondary password to the user's mobile phone or by re-entering the transmitted secondary password and confirming it.

The application of the above double security (secondary password) may be particularly applicable to a point where security is required. In addition, it can be implemented for the purpose of strengthening security during the holiday season in the case of a sign that is considered to be a security problem or in case of a company.
