In addition, in order to enhance security, the security of the door lock is strengthened by performing authentication using not only a keypad but also biometric information such as fingerprint recognition, iris recognition, and face recognition.

However, it is inconvenient to register a new password in order to register a new user in a manner of matching a password or biometric information already registered in the door lock. Also, it is difficult to open the door without giving the password in order to temporarily open the door. In other words, in the past, when there is use to allow the door to be temporarily opened, the owner must teach the password already set by the owner. In this case, the owner has to register the password of the door lock again with a new number and memorize it again. Also, there is a problem that the password can be used as a valid password until the owner manipulates the door lock and discards it.

There is an inconvenience that a guest who is staying at a pension or the like must wait for the guest to give a key to the guest in a situation where the guest does not know when. This can also be solved by switching to a digital door lock, but each time the owner of the property needs to set a new password on a daily basis.

Korean Laid-Open Patent Application No. 2014-0115631 discloses a method of opening and closing a door by mutual communication between a smartphone and a door lock.

The present invention will now be described in detail with reference to the accompanying drawings. Hereinafter, a repeated description, a known function that may obscure the gist of the present invention, and a detailed description of the configuration will be omitted. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art. Accordingly, the shapes and sizes of the elements in the drawings and the like can be exaggerated for clarity.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a door lock apparatus according to an embodiment of the present invention.

Referring to FIG. 1, a door lock apparatus according to an embodiment of the present invention includes a receiving unit 110, an authentication unit 120, and an operation unit 130.

The receiving unit 110 receives the encoded authentication number based on the combination of the password and the validity period.

In this case, the validity period means a period in which the input authentication number is valid so that the door lock device can perform the operation of opening and closing the door. For example, if the expiration date is January 1, 2015, the authorization number will be valid only on January 1, 2015, otherwise the authorization number will be invalid. That is, the door lock apparatus can be operated using the authentication number only on January 1, 2015.

In this case, the validity period can also be set in units of time. For example, on May 6, 2014, the validity period, which means between 13:00 and 22:00, can be set to 1405061322.

At this time, the validity period may be set to 2 days or more. For example, 14050602, which means that it is valid for two days from May 6, 2014, can be set as the validity period. The validity period can be set in the initial setting of the door lock device.

At this time, the password means a number set primarily for opening the door lock apparatus. The door lock device according to the embodiment of the present invention can not open and close the door only by the password, and the door lock device can be opened or closed only by inputting the authentication number in combination with the valid period and the password. At this time, the password can be set only one, or the password can be set differently according to the validity period. This will be described with reference to FIG.

In this case, the authentication number means a combination of the password and the validity period. For example, if the password is 78452 and the validity period is May 6, 2014, the authentication number may be set to 78542140506. This example is merely an example of generating an authentication number, and an authentication number can be generated using various methods. In another example, 14050678542 may be an authentication number. In order to prevent a data transmission error, a difference value between 140506 and 78542, 61964, may be included in the authentication number, and 7854214050661964 may be set as the authentication number.

At this time, there is no limit to the method by which the receiving unit 110 receives the authentication number. The user may directly input the authentication number by using the keypad in the same manner as the existing door lock or input the authentication number directly into the virtual keypad generated by the terminal using the communication means.

At this time, the authentication number can be encoded and transmitted for data transmission.

The authentication unit 120 decrypts the authentication number, determines whether the door is opened or closed based on the password and the validity period, and generates a control signal corresponding to whether the door is opened or closed.

At this time, the authentication unit 120 can extract the password and the valid period by decrypting the authentication number. For example, the authentication number before encoding is set to 78542140506, the authentication unit 120 can extract 78542140506 by decrypting the authentication number, and the password is 78542, and the effective period is 05/05/2014 Can be extracted.

At this time, the authentication unit 120 compares the password and the validity period, determines that the password is identical to the preset password, opens the door only when the current time is included in the extracted validity period, So that a corresponding control signal is generated.

At this time, the authentication unit 120 may include a synchronization unit (not shown) for synchronizing the current time recognized by the door lock apparatus with the actual current time. If the current time recognized by the door lock device differs from the actual time, the door lock device may malfunction, so that the synchronization portion may be further included for synchronizing the current time recognized by the door lock device with the actual current time.

For example, if the current time recognized by the door lock device is 05/01/14, and the actual time is April 30, 14, the current time recognized by the door lock device is synchronized with the actual time, Lt; / RTI >

For example, if the preset password is 78542, the current time is 14:00 on May 05, 06, 06, and the authentication number is 78542140506, the authentication unit 120 sets the password 78542 It is determined that the door is opened and the control signal corresponding to opening the door can be generated since the validity period is May 06, 2014 and May 14, 2014 is included in the validity period.

As another example, if the preset password is 78542, the current time is 12:05 on May 07, 2014, and the authentication number is 78542140506, the authentication unit 120 sets the password 78542 However, since the expiration date is May 6, 2014, and 12:00 on May 7, 2014 is not included in the expiration date, it is determined that the door will not be opened, and a control signal corresponding to opening the door will not be generated .

As another example, if the preset password is 78541, the current time is 14:00 on May 06, 2014, and the authentication number is 78542140506, the authentication unit 120 sets 78541 It is judged that the door is not to be opened and the control signal corresponding to opening the door can not be generated.

In the three examples, it is assumed that there is only one password, but multiple passwords can be assigned to enhance security. For example, different valid passwords may be specified for each validity period. The password can be stored in a database inside the door lock device.

At this time, when the authentication unit 120 receives a preset authentication number, it can generate and transmit a control signal corresponding to opening the door. For example, when receiving the preset authentication number 7084, it is possible to generate and transmit a control signal to directly open the door without comparing the password and the validity period. This may be used as a door lock device manager password.

The operation unit 130 performs a door locking or opening operation based on the control signal.

2 is a block diagram showing the authentication unit shown in FIG.

Referring to FIG. 2, the authentication unit 120 includes a password determination unit 210 and a validity period determination unit 220.

The password determination unit 210 determines whether the password received by the reception unit 110 matches a predetermined password.

At this time, the preset password may be a password stored in the database.

At this time, there is no limitation on the number of passwords, and there may be several passwords corresponding to each valid period. For example, if the expiration date is January 1, 2015, the password is 1234, and the expiration date is January 2, 2015, the password may be 2345 and the password may be different for each valid period. A description of the case of multiple passwords is given in FIG.

At this time, if there is no match among the previously set passwords stored in the database, the authentication unit 120 may generate a control signal corresponding to an instruction to keep the door locked.

At this time, if the received password exists among preset passwords stored in the database. The effective period determiner 220 can determine the valid period without generating the control signal immediately.

The validity period determining unit 220 compares the validity period received by the receiving unit 110 with the current time to determine whether the current time is included in the validity period.

For example, when the signal received by the receiving unit 110 is 78452140501 and the current time is 14:00 on May 01, 2014, the authentication unit 120 can determine that the validity period is May 01, 2014, Since the current time is included in the validity period as 14:00 on May 01, 2014, it can be determined that the current time is included in the validity time.

For example, when the signal received by the receiving unit 110 is 78452140501 and the current time is 02:00 on May 02, 2014, the authentication unit 120 can determine that the valid period is May 01, 2014 , It can be determined that the current time is not included in the validity period since it is the time after the validity period at 02:00 on May 02, 2014.

3 is a block diagram showing an apparatus for generating an authentication number of a door lock apparatus according to an embodiment of the present invention.

Referring to FIG. 3, an apparatus for generating an authentication number of a door lock apparatus according to an embodiment of the present invention includes an authentication information generation unit 310, an authentication number generation unit 320, and a transmission unit 330.

The device for generating the authentication number of the door lock device performs the function of generating the authentication number used in the door lock device shown in Fig.

The authentication information generation unit 310 generates authentication request information corresponding to the authentication number issue request transmitted from the user terminal.

At this time, the authentication request information is information that can recognize a user, and may include a predetermined ID, a password, and a question and an answer previously set by the door lock manager. Also, in the case of a lodging establishment, information for settlement may be included. For example, when the present invention is used in a residence, information to input a credit card number may correspond to authentication request information.

The authentication number generation unit 320 receives the authentication information corresponding to the authentication request information, generates an authentication number based on the current time and the database, and encodes the authentication number.

At this time, the database may be a place where the password corresponding to the valid period and valid period is stored in a table format.

In this case, the validity period means a period in which the input authentication number is valid so that the door lock device can perform the operation of opening and closing the door. For example, if the expiration date is January 1, 2015, the authorization number will be valid only on January 1, 2015, otherwise the authorization number will be invalid. That is, the door lock apparatus can be operated using the authentication number only on January 1, 2015.

At this time, the password means a number set primarily for opening the door lock apparatus. The door lock device according to the embodiment of the present invention can not open and close the door only by the password, and the door lock device can be opened or closed only by inputting the authentication number in combination with the valid period and the password. At this time, the password can be set only one, or the password can be set differently according to the validity period. This will be described with reference to FIG.

In this case, the authentication number means a combination of the password and the validity period. For example, if the password is 78452 and the validity period is May 6, 2014, the authentication number may be set to 78542140506. This example is merely an example of generating an authentication number, and an authentication number can be generated using various methods. In another example, 14050678542 may be an authentication number. In order to prevent a data transmission error, a difference value between 140506 and 78542, 61964, may be included in the authentication number, and 7854214050661964 may be set as the authentication number.

At this time, in the above example, it is assumed that the password is one. However, in order to enhance the security, a plurality of passwords can be designated. For example, different valid passwords may be specified for each validity period. Passwords can be stored in the database. This will be described with reference to FIG.

The device for generating the authentication number of the door lock device need not always be online when the authentication information is pre-set. However, the terminal corresponding to the user and the device for generating the authentication number of the door lock device must be connected to each other.

4 is a diagram illustrating a database used by an apparatus for generating an authentication number of a door lock apparatus and a door lock apparatus according to an embodiment of the present invention.

Referring to FIG. 4, the passwords corresponding to the validity period and the validity period are listed in a table form.

The database shown in FIG. 4 can be used to set multiple passwords for security enhancement.

For example, if the expiration date is January 1, 2015, the password used to generate the authentication number could be 8390.

For example, if the expiration date is January 2, 2015, the password used to generate the authentication number may be 1690.

For example, if the expiration date is January 3, 2015, the password used to generate the authentication number may be 9569.

For example, if the expiration date is January 4, 2015, the password used to generate the authentication number may be 2600.

For example, if the expiration date is January 5, 2015, the password used to generate the authentication number may be 5239.

A method of generating an authentication number using a database by an apparatus for generating an authentication number of a door lock apparatus will be described.

The authentication number generator 320 can generate an authentication number when the authentication information received from the user terminal is correct. At this time, if the date of generation of the authentication number is January 3, 2015, using the database shown in FIG. 5, the password becomes 9569. Therefore, the authentication number may be 9569150103. For example, when the date of generation of the authentication number is January 4, 2015, 2600 becomes the password when the database shown in FIG. 5 is used. Therefore, the authentication number may be 2600150104.

Now, the operation of the authentication unit 120 in the door lock apparatus will be described using the authentication number.

The authentication unit 120 may receive an authentication number of 9569150103 at 12:00 on January 3, 2015, and may determine that the password is 9569 and the authentication number is 150103.

At this time, the password determination unit 210 can use the database shown in FIG. 5 to determine that the password on January 3, 15 is 9569. If the received password 9569 and the password stored in the database are equal to 9569 .

At this time, the validity period determination unit 220 can determine that the current time is included in January 3, 2015, which is valid until January 3, 15,

Therefore, since the password is consistent and the current time is within the validity period, the authentication unit 120 decides to open the door, and can generate a control signal corresponding to opening the door and transmit it to the operation unit 130. [

The authentication unit 120 receives the authentication number 9569150103 at 2:00 on January 4, 2015, for example.

At this time, the password determination unit 210 determines that the password of January 3, 15, is 9569 by using the database shown in FIG. 5, and judges that the received password 9569 and the password 9569 stored in the database are the same .

At this time, the validity period determination unit 220 can determine that the current time is not included in the validity period since the current time is the time after Jan. 3, 2015, which is valid until 12:00 on January 4, 2015.

At this time, the authentication unit 120 determines that the current time is not included in the valid period, matches the password, transmits a control signal corresponding to not opening the door to the operation unit 130, ) Can not open the door.

5 is a flowchart illustrating a door lock opening / closing process according to an embodiment of the present invention.

First, the encoded authentication number is received based on the combination of the password and the validity period (S510).

In this case, step S510 may be performed by the receiving unit 110 shown in FIG.

In this case, the validity period means a period in which the input authentication number is valid so that the door lock device can perform the operation of opening and closing the door. For example, if the expiration date is January 1, 2015, the authorization number will be valid only on January 1, 2015, otherwise the authorization number will be invalid. That is, the door lock apparatus can be operated using the authentication number only on January 1, 2015.

At this time, the password means a number set primarily for opening the door lock apparatus. The door lock device according to the embodiment of the present invention can not open and close the door only by the password, and the door lock device can be opened or closed only by inputting the authentication number in combination with the valid period and the password. At this time, the password can be set only one, or the password can be set differently according to the validity period. This will be described with reference to FIG.

In this case, the authentication number means a combination of the password and the validity period. For example, if the password is 78452 and the validity period is May 6, 2014, the authentication number may be set to 78542140506. This example is merely an example of generating an authentication number, and an authentication number can be generated using various methods. In another example, 14050678542 may be an authentication number. In order to prevent a data transmission error, a difference value between 140506 and 78542, 61964, may be included in the authentication number, and 7854214050661964 may be set as the authentication number.

At this time, there is no limitation on the method of receiving the authentication number. The user may directly input the authentication number by using the keypad in the same manner as the existing door lock or input the authentication number directly into the virtual keypad generated by the terminal using the communication means.

At this time, the authentication number can be encoded and transmitted for data transmission.

Further, the authentication number is encoded, and it is determined whether the door is opened or closed based on the password and the validity period (S520).

In this case, step S520 may be performed in the authentication unit 120 shown in FIG.

At this time, the authentication unit 120 can extract the password and the valid period by decrypting the authentication number. For example, the authentication number before encoding is set to 78542140506, the authentication unit 120 can extract 78542140506 by decrypting the authentication number, and the password is 78542, and the effective period is 05/05/2014 Can be extracted.

At this time, the authentication unit 120 compares the password and the validity period, determines that the password is identical to the preset password, opens the door only when the current time is included in the extracted validity period, So that a corresponding control signal is generated.

For example, if the preset password is 78542, the current time is 14:00 on May 05, 06, 06, and the authentication number is 78542140506, the authentication unit 120 sets the password 78542 It is determined that the door is opened and the control signal corresponding to opening the door can be generated since the validity period is May 06, 2014 and May 14, 2014 is included in the validity period.

As another example, if the preset password is 78542, the current time is 12:05 on May 07, 2014, and the authentication number is 78542140506, the authentication unit 120 sets the password 78542 However, since the expiration date is May 6, 2014, and 12:00 on May 7, 2014 is not included in the expiration date, it is determined that the door will not be opened, and a control signal corresponding to opening the door will not be generated .

As another example, if the preset password is 78541, the current time is 14:00 on May 06, 2014, and the authentication number is 78542140506, the authentication unit 120 sets 78541 It is judged that the door is not to be opened and the control signal corresponding to opening the door can not be generated.

In the three examples, it is assumed that there is only one password, but multiple passwords can be assigned to enhance security. For example, different valid passwords may be specified for each validity period. The password can be stored in a database inside the door lock device.

Further, a control signal corresponding to whether the door is opened or closed is transmitted (S530).

In addition, based on the control signal, either the door lock operation or the door open operation is performed (S540).

In this case, step S530 may be performed in the authentication unit 120 shown in FIG. 1, and step S540 may be performed in the operation unit 130 shown in FIG.

6 is a flowchart illustrating an operation of generating an authentication number between a terminal and an authentication number generating apparatus and opening and closing the door using an authentication number between the terminal and the door lock apparatus.

Referring to FIG. 6, the terminal requests the authentication number generation device to issue an authentication number (S610).

The authentication number generation device generates authentication request information (S611), and transmits the authentication request information to the terminal (S612).

At this time, the authentication request information is information that can recognize a user, and may include a predetermined ID, a password, and a question and an answer previously set by the door lock manager. Also, in the case of a lodging establishment, information for settlement may be included. For example, when the present invention is used in a residence, information to input a credit card number may correspond to authentication request information.

At this time, the terminal and the authentication number generating device can perform the respective steps by the communication means. The communication means is not limited. Existing wireless communication means such as WIFI and Bluetooth may be used.

At this time, the authentication number generating device may be included in the door lock device and used.

Further, after the authentication information is input in the terminal (S620), the terminal transmits the authentication information to the authentication information generating device (S621).

Further, the authentication number generation device confirms the authentication information (S622).

Further, the authentication number generating device generates an authentication number (S623).

At this time, the authentication number generation device can generate the authentication number only when the authentication information is valid. If the authentication information is not correct, the authentication number generation device may terminate the procedure without generating the authentication number, As shown in FIG.

At this time, the authentication number generator 320 in the authentication number generator can perform S623.

At this time, in generating the authentication number, the authentication number may be generated based on the current time and the database.

At this time, the database may be a place where the password corresponding to the valid period and valid period is stored in a table format.

In this case, the validity period means a period in which the input authentication number is valid so that the door lock device can perform the operation of opening and closing the door. For example, if the expiration date is January 1, 2015, the authorization number will be valid only on January 1, 2015, otherwise the authorization number will be invalid. That is, the door lock apparatus can be operated using the authentication number only on January 1, 2015.

At this time, the password means a number set primarily for opening the door lock apparatus. The door lock device according to the embodiment of the present invention can not open and close the door only by the password, and the door lock device can be opened or closed only by inputting the authentication number in combination with the valid period and the password. At this time, the password can be set only one, or the password can be set differently according to the validity period. This is described in FIG.

In this case, the authentication number means a combination of the password and the validity period. For example, if the password is 78452 and the validity period is May 6, 2014, the authentication number may be set to 78542140506. This example is merely an example of generating an authentication number, and an authentication number can be generated using various methods. In another example, 14050678542 may be an authentication number. In order to prevent a data transmission error, a difference value between 140506 and 78542, 61964, may be included in the authentication number, and 7854214050661964 may be set as the authentication number.

Further, the authentication number generation device transmits the authentication number to the terminal (S624).

At this time, there is no limitation on the method of transmitting the authentication number to the terminal. The authentication number can be transmitted to the user terminal via SMS, SNS, or the like, and the authentication number can be transmitted to the terminal using an e-mail or an application.

Also, the terminal inputs the authentication number to the door lock device (S630).

At this time, there is no restriction on the way in which the terminal inputs the authentication number. For example, when an authentication number is transmitted to a terminal by SMS, the application can automatically read the authentication number inside the SMS and automatically transmit the authentication number to the door lock device through the application. Alternatively, it may be input from a keypad connected to the door lock device.

Further, the door lock apparatus receives the authentication number (S631).

At this time, the authentication number can be encoded and transmitted for data transmission, and the encoded authentication number can be decrypted by the door lock device and receive the authentication number.

At this time, the received authentication number is a combination of a password and a validity period, and can extract a password and a validity period based on predetermined conditions. For example, the authentication number before encoding is set to 78542140506, and the authentication unit 120 performing S631 can extract 78542140506 by decrypting the authentication number. The password is 78542, and the validity period is 2015 year 05 06 < / RTI >

Further, the door lock apparatus confirms the password (S632).

At this time, if the pre-stored password and the received password are different, the process of opening the door can be terminated.

If the pre-stored password and the received password are identical, the process can proceed to step S633.

Further, the door lock apparatus confirms the valid period (S633).

At this time, if the current time is within the received validity period, the process can proceed to step S634, and if the current time is not within the received validity period, the process of opening the door can be terminated.

At this time, the current time recognized by the door lock device may be synchronized with the actual current time. If the current time recognized by the door lock device differs from the actual time, the door lock device may malfunction, so that the step of synchronizing the current time recognized by the door lock device with the actual current time may be further included.

For example, if the current time recognized by the door lock device is 05/01/14, and the actual time is April 30, 14, the current time recognized by the door lock device is synchronized with the actual time, Lt; / RTI >

Further, the door lock device opens the door (S634).

At this time, it is determined that the door is opened only when the password matches the validity period and the password matches the predetermined password, and the current time is included in the extracted validity period, and the door can be opened.

For example, if the preset password is 78542, the current time is 14:00 on May 05, 06, 06, and the authentication number is 78542140506, the authentication unit 120 sets the password 78542 And the validity period is May 06, 2014 and May 14, 2014 is included in the validity period, so that it is determined that the door is opened and the door can be opened.

As another example, if the preset password is 78542, the current time is 12:05 on May 07, 2014, and the authentication number is 78542140506, the authentication unit 120 sets the password 78542 However, since the expiration date is May 6, 2014, and 12:00 on May 7, 2014 is not included in the validity period, it is decided that the door will not be opened and the door may not be opened.

As described above, the door lock device, the device for generating the authentication number of the door lock device, and the door lock opening / closing process method according to the present invention are not limited to the configuration and method of the embodiments described above, All or some of the embodiments may be selectively combined so that various modifications may be made.
