Description

{0001} Digital door lock device and digital door lock security service method with communication module {

As the standard of living has improved, the need for security has increased, and the demand for digital door locks has increased due to the convenience of not having to carry a key.

The types of door locks currently used can be summarized as follows.

(A) Door lock with key and lock

(B) Door lock by password (password)

(C) Door lock by biometric technology such as fingerprint recognition

(D) Door lock by card recognition (mainly RF applied)

(E) Door lock by the combination application of said (A), (B), (C), (D)

The said (E) system is mainly comprised by the hybrid system including the said (B) system, and also including another system (namely, (A), (C), or (D) system).

In addition to improving living standards, there is an increasing need for additional functions beyond simple security through door locks.

By inputting and outputting the desired message in the door lock, a person or company can publicize themselves and leave a desired message to an authorized user of the door lock (eg, a family member or co-worker).

[For public use message ]

Although not necessarily described in the present invention, the 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 the user (public PR message or a private message provided to an authorized user) to the display device. A " message " includes " text message (visual message) " and " voice message (auditory message) ".

In the case of digital door locks, most of them have a basic method of authenticating by a password (password). This is because it is inexpensive compared to the biometric method and does not have a key. In the case of a password method, since a numeric keypad is usually provided, it can be used as a keypad for text input. In the present invention, the door lock may be additionally configured not only a password method but also a biometric method such as an RF card method and a fingerprint.

FIG. 1A is a conceptual block diagram of a case in which a message input / output function is additionally provided in a door lock having a numeric keypad, and FIG. 1B is a configuration diagram in this case. In FIG. 1B, the Korean keypad for Hangul character input technology presented by the applicant has been presented, but it is obvious that any character input technology can be applied. In Fig. 1B, the case of simply displaying a "public PR message" is given. Generating a message based on the input value is performed inside the door lock. In FIG. 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 the "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 is represented that there are branch inputs 13 and 14.

Also, due to the small size of the display device (eg liquid crystal), the message may not be displayed. To solve this, it is possible to make the message appear sliding. For example, if only one line is displayed, the message slides from right to left. Even if multiple lines are displayed, it is possible to make the entire message appear by sliding up and down.

In the past, when a general house was generalized, there was a nameplate, and in a hard age when only the number (apartment lake) remains as the residential environment is converted into an apartment, the message for the door lock disclosure of the present invention can be expected to provide softness. . You can put the phrase "This is a security company!"

[Private message ]

In some cases, it may not be just a public message that is open to everyone. For example, “My dear son, I am late today. Evening meals can't be made public so that everyone can see them. ” This is because the thieves advertise that the house is empty. It should only be visible to certain authorized users. Therefore, it should be stored as a "private message" and only authorized users can view the message.

A typical way of viewing a message would be to enter a user ID and a password that corresponds to that user ID. Recently, however, a door lock system has been introduced to designate a large number of passwords and to allow users to use their own passwords. 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 designated to 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 or her password, selects the user who will deliver the message from the user list, and writes the desired message after selecting the user. Similarly, the process of outputting a private message is possible by a procedure in which a user to receive the message is authorized (the corresponding password is input) and a process of outputting the message.

For example, the mother saves the private message (“Love Son, I'm late today. Dinner will be resolved…”) for the password (password) “1111” or “ㄱㄱㄱㄱ” that the son uses. After the procedure of saving as a message or storing as voice), when the son returns home and enters the promised password (“1111” or “ㄱㄱㄱㄱ”), the message is output in the promised manner (output in the display window of the door lock, text). To convert the voice to voice or output the stored voice) to process the private message. Preferably, after the message has been output, if the user takes some action (e.g., presses the "OK" button or the "Delete" button), the door lock opens or after a certain time (e.g. 3 seconds) after outputting the entire message. The door lock can also be opened.

In the keypad illustrated in Fig. 1A, “[1] button = [a] button”, and the scan code (the unique key value defined for each key) are the same. Therefore, regardless of whether the user is aware of or enters “1111” or “a ㄱㄱㄱ”, the door lock recognizes the same. Therefore, the password is expressed as “1111” or “ㄱㄱㄱㄱ”. This is the same as entering the Korean [ㅁ] key, entering the English [a] key or recognizing the same password when entering the password on the PC. [1] ~ [0] The numeric buttons are the same for all products, so in the following, the numeric values are mainly displayed as passwords.

[External Interface Module]

The present invention is not applicable only to a password-type door lock, and in the case of a door lock without a keypad as an input device, an interface module 23 connected to a separate built-in input device or an external input device (wired or wirelessly connected) Have). In addition, even if the door lock is provided with the input device 23, it is possible to input a desired message through an external input device (eg, mobile phone, PC) desired by the user.

2A is a block diagram when an external input device is used. When using an external input device without using an internal input device (eg, a keypad of a door lock) provided in the door lock itself, only the scan code value (a unique key value defined for each key) required for character generation in the external input device is used. A message can be generated from the door lock, and a message generated from an external input device can be received and displayed. The former is a case where a message for the input value is generated in the door lock as shown in Figure 1b, the latter is a message generated by the external input device to deliver the message generated 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, and landline. It can be achieved by the communication function (eg CDMA, GSM) and the short message transmission function of the mobile phone. 2B is a configuration diagram when an external input / output device 27 is applied to a mobile phone or a similar terminal having a communication function of the mobile phone. In FIG. 2B, an example of posting a public PR message of a company is given.

In the case of applying a non-short-range wireless communication means such as infrared communication or Bluetooth (e.g., CDMA or GSM), there is an advantage in that the door lock can be controlled (eg, message registration) at 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 in reality.

[Notified User]

In addition, the door lock may be provided with a wired or wireless communication module 38. See Figure 3. Wired communication is typical telephone and wireless communication is typical mobile phone communication function. 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 may be viewed as a communication means with an external device. The wired and / or wireless interface module 37 in FIG. 3 may be provided as in FIG. 2A or may not be provided as in FIG. 1A. In the case where 37 as mobile communication is provided, realistically 38 as mobile communication will be configured with 37, but is conceptually shown separately. Likewise, if 37 is provided as wired communication (eg the Internet), it will be configured with 38 as wired communication in practice.

When a door lock is opened with the first output of a private message, a message (a text message or a voice message) is transmitted to the mobile phone of the promised user (for example, the user who has input the private message or the entire administrator) It is possible. For example, it informs the promised user that "the message was output to his son (user of" 1111 "password) at xx hour xx minute xx seconds xx date xx xx 2006". If in all cases a text message is sent to or from a particular user (a son using the password “1111” or “ㄱㄱㄱㄱ” in the case), if the son opens and closes the door lock 10 within 10 minutes, 10 characters within 10 minutes. The message will be sent, because it causes a tremendous waste in operating costs and is very annoying for spammers as a user.

In the case of private messages, when a specified number of users are specified, each user first reads the message (that is, the doorlock outputs the message for the first user for the first time). Can be.

That is, in addition to the above-described procedure, a procedure for confirming whether a private message is first outputted to a user to be viewed, and notifying a promised user of the fact (message output fact) if the private message is output for the first time. It includes additional procedures.

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

Furthermore, even if there is no private message, the promised user (e.g. highest) only when the first user opens the door lock in a certain time zone (e.g. 0 to 24 o'clock, 13 o'clock or 24 o'clock, or 06 o'clock to 12 o'clock). It is possible to notify the administrator (text message or voice message). A family example can help mothers who are going out to know when they are home.

[User Management]

The management of the user can be made similar to the 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, the specific user is not recognized by the ID and password, but the password itself has a specific user authentication function.

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

Here, whether or not a user designated as an administrator by the super administrator has the same authority as the super administrator (eg, creation of a password, that is, creation of a user, etc.) is a matter of operation policy and thus will not be discussed further. In addition, whether to subdivide the user class or to make a public message with general user authority is a detail problem in the operation policy, so it is not mentioned anymore.

First, when the super administrator enters the super administrator password and enters the management mode to query the list of registered users, 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 Username authority (cellphone) 7777 or us Supervisor

If a user is added according to a predetermined procedure (e.g., pressing a menu button and selecting add password from a menu that is created), the user will be as follows. The following is an example of modifying super administrator information and adding users. The user name may be viewed as an alias registered to make it easy to identify who the user of a specific password is, and may register the user's name or position. In reality, the chief administrator will be the security officer of the organization (company or home) or a representative of a security guard company.

password Username authority (cellphone) 7777 or us Security officer Supervisor (010-7777-7777) 5555 or ㅁㅁㅁㅁ CEO manager (010-5555-5555) 3333 or ㄷ ㄷㄷㄷ Temple Normal

Conventionally, user-friendly interface implementation (eg user name input and display) would not be possible in a door lock without a display device (e.g. liquid crystal) and an input device. However, if 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 management details will also be displayed on the display device of the external input device (eg, the screen of a PC or the liquid crystal of a mobile phone), not the liquid crystal of the door lock. Of course, once the management details (e.g. the creation of a public message) are completed, the public message 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 the user and the remote site. In addition, a contact number such as a mobile phone is indicated in parentheses because it is not necessary when the communication module 38 is not added to the door lock itself.

When creating a public message (eg, pressing the menu button and selecting Create a Public PR Message), you can enter the public message creation screen and save the message after creating it. If you want to modify the information of a specific user, select the specific user and enter the “edit information” to perform the information modification. 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” menu (eg press the Menu button and select Create Private Message). Just do it.

It is important to note that if a general user (eg son) using the password “1111” or “ㄱㄱㄱㄱ” enters administrative mode, the user's list should not be visible to others. That is, it is preferable that a user (password) list is displayed as in the following example. Whether or not to allow cell phone numbers to be viewed under normal user rights is also a matter of operational policy.

password Username authority (cellphone) **** Security officer Supervisor (010-7777-7777) **** CEO manager (010-5555-5555) 3333 or ㄷ ㄷㄷㄷ Temple Normal

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

In the example, the password is expressed as four digits for convenience, but security can be strengthened by specifying the minimum number of password digits according to the security policy.

[Emergency contact]

If a voice call function is added to the communication module 38 in the door lock, an unauthorized visitor (i.e., a visitor who has not been given a password) is allowed to make an emergency call (eg a phone call) to a promised user (e.g., a super administrator). 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, super administrator) are not exposed. This means, for example, that the courier can cope with his / her absence without notifying the baggage recipient's mobile phone number in advance. In addition, the emergency contact phone number is registered as the security guard's phone number can be used in an emergency.

[Security anomaly notice]

When the communication module 38 is attached to the door lock, when a security abnormality sign (e.g., a password mismatch more than a certain number of times (e.g. 3 times)) occurs, the user (e.g., a supervisor or a security guard company) Notification service (text or voice) is available.

Expressed as a procedure, a procedure for counting password inconsistencies, a procedure for checking occurrences of inconsistencies more than a predetermined number of times, and a procedure for notifying the corresponding contactee by means of a promised means.

[Dual security, secondary password]

When a wired or wireless communication module 38 is added to the door lock, double security is possible by inputting a secondary password for the user. In the example, if the “boss” password (in this case the primary password) “5555” is exposed, the unauthorized user can open the door lock. However, according to the security policy (e.g., the super administrator sets the second password application), when entering “5555”, the secondary password is assigned to the registered president's mobile phone number “010-5555-5555”. A password or a random number generated by a door lock) may be transmitted as a text message, and a second password may be re-entered within a predetermined time (eg 30 seconds) to open the door lock.

In the application of a secondary password, the entry of the primary password serves to identify (not approve) the user, and this user identification can not only be achieved by entering the primary password, but also biometrics (eg fingerprint recognition). ), User identification may be performed by RF card recognition. The second password can be sent to the mobile phone registered with the user and the user can be entered to complete the double security. In the above example where only the primary password was applied, using the RF card as the user identification, the user database would be as follows.

RF card Username authority (cellphone) Card 1 Security officer Supervisor (010-7777-7777) Card2 CEO manager (010-5555-5555) Card3 Temple Normal

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

In this case, the person who attempts to break into the system will not be able to open the door lock simply by obtaining the available password (primary password), and the security of the user will be required because the user's mobile phone must also be the password.

However, having to enter a secondary password all the time can be inconvenient, and according to security policy, for example, if a particular user successfully authenticates with the secondary password for the first time for a period of time (eg a day), During the day, you can operate without asking for the secondary password. This security policy profile can also be specified by the super administrator.

To reorganize the above cases, the process of recognizing the user (by inputting the primary password, biometrics or RF card), checking whether the secondary password was authenticated within a predetermined period of time, and if so, opens the door lock. Otherwise, the second password may be transmitted to the user's mobile phone, and the second password may be input again and confirmed.

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

To reorganize the above cases, the process of recognizing the user (by inputting the primary password, biometric or RF card), the process of requesting the input of the secondary password, and the registration of the second password if there is no input of the secondary password within a certain time The second password may be transmitted to the user's mobile phone, and the second password may be input again and confirmed.

The above application of double security (secondary password) may be particularly applicable to the point where security is required. It can also be implemented for security purposes in the event of signs of a security breach or in the case of a company.
