Next, a method for object-internet-based door lock control according to an embodiment of the present invention will be described. 4 is a diagram for explaining an observation mode according to an embodiment of the present invention. And FIG. 5 is a flowchart for explaining a method for controlling the object Internet-based door lock according to an embodiment of the present invention.

4 and 5, the controller 260 of the door lock control apparatus 200 is in the observation mode at step S100. In the observation mode, the control unit 260 turns the camera unit 220 on. The control unit 260 detects whether the object is approaching within a predetermined radius R based on any one reference point S of the door 10 through the ultrasonic sensor unit 240. Here, the object is a person, and the control unit 260 estimates the moving object as a person.

When a person enters the predetermined radius R, the control unit 260 continuously captures an object through the camera unit 220, and stores the captured image in a buffer having a predetermined size of the storage unit 250. If the storage space of the buffer is insufficient, the newly captured image is continuously stored in the buffer through overwriting. This observation mode is continuously performed until the power of the door lock control device 200 is turned off. Therefore, the observation mode indicated by reference numeral S100 is performed only in the observation mode, and the other steps indicated through the other reference signs are performed simultaneously with the observation mode and other tasks .

During the observation mode, the control unit 260 can sense an impact applied to the door through the impact sensor unit 230 in step S110. If an impact is detected, the controller 260 determines in step S120 whether the impact detected earlier is equal to or greater than a predetermined threshold value. If it is determined in step S120 that the detected impact is less than the predetermined threshold value, the controller 260 proceeds to step S100 and switches to the observation mode. On the other hand, if it is determined in step S120 that the sensed impact is equal to or greater than the preset threshold value, the controller 260 proceeds to step S130.

The control unit 260 performs a reporting process in order to report such a situation to the manager through the image according to the embodiment of the present invention because the possibility of a trespassing or the like is high. In particular, an event that triggers the reporting process is referred to as a reporting event. In this embodiment, it is a reporting event to sense an impact above a threshold value.

For the reporting process, the controller 260 edits the image to generate a report image, and stores the generated report image in the storage unit 250 in order to inform the manager of the image including the situation that the impact is applied to the door in step S130 . That is, the report image can be an image of a situation where an impact is applied to the door. In step S130, the control unit 260 extracts an image before and after a predetermined period of time at a time point when an impact is detected among the images captured through the camera unit 220 in the observation mode and stored. That is, the control unit 260 extracts an image before and after a predetermined period of time at which a shock is detected, which is a reporting event occurrence time that triggers the reporting process. In addition, the control unit 260 identifies a face of a person in the extracted image through object recognition so as to easily identify the person who applied the shock, and captures an image in which a face of the person is identified. Thereby, a report image is generated. That is, the report image includes the extracted image and the captured image. After generating the report image, the control unit 260 stores the report image in the storage unit 250. In the embodiment of the present invention, the controller 260 of the door lock control apparatus 200 may perform functions of an application server and a web server, and the storage unit 250 may serve as a database server. Accordingly, the location where the report image is stored can be identified through the URL.

Then, the control unit 260 transmits the report image stored in the storage unit 250 to the first user device 301 in step S140. Here, the report image may be transmitted to the first user device 301 in a push service or a server push manner. That is, the controller 260 of the door lock control device 200 may perform functions of an application server and a web server for providing a push service. The push service may, for example, illustrate Apple's APNS (Apple Push Notification Service) and Google's GCM (Google Cloud Messaging). Accordingly, the control unit 260 transmits a message (e.g., notification) including a location (e.g., URL) where the report image is stored. This message is then forwarded to the first user device 301 via a push server (e.g., a GCM server or an APNS server). Then, the control module 350 of the first user device 301 receives the message through the communication module 310, accesses the door lock control device 200 by referring to the URL of the message, method will be downloaded. The control module 350 may then store the report image in the storage module 340 and display it via the display module 330. [ The user can view the report image and take necessary actions. As described above, according to the embodiment of the present invention, when a shock occurs in the door, since the state before and after the occurrence of the shock is transmitted to the manager as a report image, a high level of security service can be provided .

Next, a method for object-internet-based door lock control according to another embodiment of the present invention will be described. 6 and 7 are flowcharts for explaining a method for object-internet-based door lock control according to another embodiment of the present invention.

Referring to FIGS. 6 and 7, the controller 260 of the door lock control device 200 is in the observation mode at step S100. This observation mode is as described above with reference to FIGS. 4 and 5.

During the observation mode, the controller 260 checks whether a number is inputted through the keypad 110 of the door lock 100 in step S210. If it is determined that the number is input, the controller 260 determines whether the number matches the preset number in step S220. Here, the request number is a preset number for requesting the manager to request to open the door. The request number may use a special key. In this case, the keypad 110 may have a special key.

If it is determined in step S220 that the inputted number is a special number (a special key is input if there is another special key), the controller 260 proceeds to step S310. On the other hand, if it is determined in step S220 that the inputted number is not the request number (if there is a special key, the special key is input), the controller 260 proceeds to step S230.

In step S230, the controller 260 determines whether or not the entered number matches the access number (S210). As a result of the determination in step S230, if the input number does not match the access number, the controller 260 proceeds to step S240. If the input number matches the access number, the controller 260 proceeds to step S280.

In step S240, the control unit 260 increases the number of inconsistencies because the input number does not match the access number. In step S250, the controller 260 determines whether the number of mismatches is equal to or greater than a predetermined number. If the result of the determination is less than the preset number of times (for example, three times), the control unit 260 returns to step S100. On the other hand, if it is determined that the number of inconsistencies is greater than or equal to the predetermined number, the control unit 260 performs steps S260 and S270 in the reporting process to report the situation to the administrator . Steps S260 and S270 are performed as described above in steps S130 and S140.

That is, in step S260, the control unit 260 edits the image to generate a report image to report to the administrator an image containing the situation when the inconsistency of the access number occurs more than a predetermined number of times, and transmits the generated report image to the storage unit 250. [ . Here, the report image is a picture of a situation where an impact is applied to the door. More specifically, the control unit 260 controls the control unit 260 to perform a predetermined period of time at a point in time at which the access number mismatch occurs more than a predetermined number of times, that is, at the time of occurrence of the reporting event triggering the reporting process, And extracts the before and after images. In addition, the controller 260 identifies the face of the person in the extracted image through object recognition so as to easily identify the person who entered the number, and captures an image in which the face of the person is identified. Thereby, a report image is generated. That is, the report image is the extracted image and the captured image. Then, the control unit 260 stores the report image in the storage unit 250. As described above, the location of the stored report image can be identified through the URL.

Next, the controller 260 transmits the report image stored in the storage unit 250 to the first user device 301 in step S270. Here, the report image may be transmitted to the first user device 301 in a push service or a server push manner. The description thereof is as described in step S140. In addition, as described above, the first user device 301 can also download the report image according to the push service method and display the report image. Thus, the user can view the report image and take necessary actions. As described above, according to the embodiment of the present invention, when the access number mismatch occurs more than a predetermined number of times, all of the before and after the situation are transmitted to the manager as a report image, so that a high level of security service can be provided.

On the other hand, if it is determined in step S230 that the input number matches the access number, the controller 260 controls the opening / closing device 120 of the door lock 100 to unlock the door lock in step S280. Thereby, the door is opened. In the embodiment of the present invention, an event triggering to release the lock of the door lock will be referred to as an access event. In this embodiment, the access event is an event in which it is determined that a number matching the access number is input.

In step S290, the control unit 260 stores the access information including at least one of the time at which the door is opened, the time at which the access event occurred, and the access event type in the storage unit 250. The control unit 260 transmits the access information to the first user device 301 in step S300.

The transmission of access information can also be carried out in a push service manner like a report image. The first user device 301 can also download access information according to the push service method. The control module 350 of the first user device 301 accumulates access information in the storage module 340 and stores it. When the administrator requests the input through the input module 320, the control module 350 loads the cumulatively stored access information from the storage module 340 and displays it through the display module 330.

On the other hand, if it is determined in step S220 that the inputted number is a request number (a special key is input in the case of a special key), the control unit 260 transmits a report number S310 and S320 are performed. That is, in step S310, the control unit 260 edits the image to generate a report image, and stores the generated report image in the storage unit 250 in order to deliver the image containing the figure of the person who has inputted the request number to the manager. Here, the report image is an image containing the image of the person who has input the request number. More specifically, the control unit 260 extracts an image before and after a predetermined period at a point in time when a request number is input, that is, at the time of generating a reporting event triggered by the reporting process, among the images captured and stored through the camera unit 220 . In addition, the controller 260 identifies the face of the person in the extracted image through object recognition so as to easily identify the person who entered the number, and captures an image in which the face of the person is identified. Thereby, a report image is generated. That is, the report image is the extracted image and the captured image. Then, the control unit 260 stores the report image in the storage unit 250. As described above, the location of the stored report image can be identified through the URL.

In step S320, the control unit 260 transmits the report image stored in the storage unit 250 to the first user device 301. In step S320, Here, the report image may be transmitted to the first user device 301 in a push service or a server push manner. The description thereof is as described in step S140. In addition, as described above, the first user device 301 can also download the report image according to the push service method and display the report image. Accordingly, the manager can view the report image and take necessary actions. At this time, when the manager wants to allow the person who inputted the request number through the reporting image, the manager inputs the request to allow the access. Then, when the control module 350 of the first user device 301 receives the input of the manager through the input module 320, the door lock controller 200 ).

In step S330, the controller 260 of the door lock control device 200 determines whether an open command is received within a predetermined period of time through the communication unit 210. [ The controller 260 controls the opening and closing device 120 of the door lock 100 to open the door and the controller 260 controls the opening / Stores the access information including the time when the door is opened in the storage unit 250 in step S290, and transmits the access information to the first user device 301 in step S300. As described above, according to the embodiment of the present invention, a user who does not know or can not access the access number requests access through the video, and the manager provides a convenient user experience (UX) for viewing and remotely viewing such images .

On the other hand, if the open command is not received within a predetermined time, the controller 260 may output a message indicating that the request is not accepted through the speaker 130 of the door lock 100 in step S340. Then, the control unit 260 returns to step S100.

Next, a method for object-internet-based door lock control according to another embodiment of the present invention will be described. FIG. 8 is a flowchart illustrating a method for object-internet-based door lock control according to another embodiment of the present invention.

4 and 8, the controller 260 of the door lock control device 200 is in the observation mode at step S100. This observation mode is as described above with reference to FIGS. 4 and 5.

During the observation mode, the control unit 260 determines whether the user is detected within a predetermined area A for a predetermined time or longer through the ultrasonic sensor unit 240 in step S410. As shown in Fig. 4, the predetermined area A is right in front of the door 10. As shown in Fig. That is, in step S410, the controller 260 determines whether the user stands in front of the door 10 for a predetermined time or longer.

Then, the controller 260 performs authentication through the device in step S420. Here, the authentication through the device is performed by the second user device 302 and the door lock control device 302 in order to open the door without any additional operation when a legitimate user who is allowed to enter and leave the second user device 302 is standing in front of the door. (200). ≪ / RTI > This procedure will be described in more detail below. That is, the control unit 260 authenticates whether or not the second user device 302 is a legitimate user device permitted to enter and exit in step S420. In accordance with this authentication procedure, the controller 260 determines whether the authentication is successful in step S430. If it is determined that the authentication is not successful, the control unit 206 returns to step S100.

On the other hand, if the authentication is successful (i.e., when an access event occurs), the controller 206 controls the opening / closing device 120 of the door lock 100 to open the door in step S440, similar to steps S280 through S300. Then, the control unit 260 stores the access information including the time when the door is opened in the storage unit 250 in step S450. The controller 260 transmits the access information to the first user device 301 in step S460.

Hereinafter, an authentication method using a device according to an embodiment of the present invention will be described in more detail. Before performing the authentication procedure, the administrator registers the user's second user device 302 in the door lock control device 200 so that a legitimate user can unlock the door without any operation.

First, the registration procedure will be described. 9 is a flowchart illustrating a method for registering a device for door lock control based on the object Internet according to another embodiment of the present invention. In Fig. 9, the first user device 301 of the administrator describes a procedure of registering the user's second user device 302 in the door lock control device 200. Fig. It is assumed in FIG. 9 that the first user device 301 and the second user device 302 are located within a distance that enables a peer-to-peer connection (for example, Bluetooth pairing) between each other. Accordingly, the registration procedure shown in FIG. 9 can be a procedure for allowing the administrator to confidently identify himself / herself and granting authority to allow access to the second user device 302, which is the portable device of the user.

In step S510 of FIG. 9, the device ID (IDA) of the door lock control device 200 is stored in the storage module 340 of the first user device 301. FIG. The device identifier (IDA) is an identifier that can uniquely identify the door lock control device 200 by distinguishing it from other door lock control devices. The device identifier (IDA) may be a bit string of a predetermined length having the same number of bits 0 and 1 in a bit string. For example, it is assumed that the device identifier (IDA) is equal to 'IDA = {0011}'.

If there is an input from an administrator in step S520, the first user device 301 is paired between the first user device 301 and the second user device 302. After the pairing, the control module 350 of the second user device 302, in step S530, identifies the second user device 302 through the communication module 310 by using a user identifier IDU) to the first user device (301). Here, the user identifier (IDU) may be a bit string of a predetermined length having the same number of bits 0 and 1 in a bit string. For example, it is assumed that the user identifier (IDU) is equal to 'IDU = {1100}'.

The control module 350 of the first user device 301 receiving the user identifier (IDU) generates an authenticator (CER) in step S540. Here, the authenticator (CER) may be a random number (random number) generated through a random function. The authenticator (CER) may be a bit string of a predetermined length having the same number of bits 0 and 1 in a bit string. For example, assume that the authenticator (CER) is equal to 'CER = {1001}'.

Next, the control module 350 of the first user device 301 receives the first cipher text COD1 through the first cryptographic function E1 () as a factor of the authenticator (CER) and the user identifier (IDU) in step S550 . That is, the control module 350 of the first user device 301 generates the first cipher text COD1 by encrypting the authenticator (CER) with the user identifier (IDU) in step S550. For example, the first cryptographic function E1 () is given by Equation 1 below.

[Equation 1]

IDU = COD1, 여기서,

는 XOR 연산자E1 (seed, idu) = CER

IDU = COD1,

Is an XOR operator

According to the above assumption, when the authenticator (CER) is 'CER = {1001}' and the user identifier (IDU) is 'IDU = {1100}', according to the first cryptographic function E1 The first cipher text (COD1) becomes 'COD1 = {1010}'.

The control module 350 of the first user device 301 then transmits the second cipher text COD2 through the second cryptographic function E2 () as a factor of the first cipher text COD1 and the device identifier IDA in step S560 . For example, the second cryptographic function E2 () is represented by the following equation (2). That is, the control module 350 of the first user device 301 encrypts the first cipher text COD1 encrypted with the user identifier (IDU) again with the device identifier (IDA) in step S560, 2 cipher text (COD2). For example, the second cryptographic function E2 () is represented by the following equation (2).

IDA = COD2, 여기서,

는 XOR 연산자E2 (cod1, ida) = COD1

IDA = COD2,

Is an XOR operator

The first cipher text COD1 derived through Equation 1 is 'COD1 = {1010}', and when the device identifier IDA is 'IDA = {0011}' as previously assumed, The second cipher text (COD2) becomes 'COD2 = {0110}' according to the second cryptographic function E2 ().

Next, the control module 350 of the first user device 301 transmits the second cipher text 'COD2 = {0110}' to the second user device 302 through the communication module 310 in step S570. Then, the control module 350 of the second user device 302 stores the second cipher text COD2 'COD2 = {0110}' in the storage module 340 in step S580.

Meanwhile, the control module 350 of the first user device 301 transmits the authenticator (CER) 'CER = {1001}' to the door lock control device 200 through the communication module 310 in step S590. Then, the controller 260 of the door lock control device 200 stores the authenticator (CER) 'CER = {1001}' in the storage unit 250 in step S600. As a result, the second user device 302 is registered in the door lock control device 200.

When the registration procedure described in FIG. 9 is completed, the user can unlock the door through the second user device 302 without any input. This procedure will be described. FIG. 10 is a flowchart illustrating an authentication method for object-based Internet-based door lock control according to another embodiment of the present invention. The embodiment of FIG. 10 is a detailed description of step S420 of FIG.

8, the control unit 260 of the door lock control device 200 performs an authentication process when the user detects a predetermined time or more in the predetermined area A through the ultrasonic sensor unit 240 in step S410 . Here, it is assumed that the user is carrying the second user device 302. In step S610, the controller 260 of the door lock control device 200 transmits an authentication start message to the second user device 302 through the communication module 210 to notify the second user device 302 to start the authentication process.

The second user equipment 302 having received the authentication start message transmits the second cipher text 'COD2 = {0110}' stored in the storage module 340 to the door lock control device 200 in step S620. The controller 260 of the door lock control device 200 generates a third cipher text COD3 through the third cryptographic function E3 () with the second cipher text COD2 and the device identifier IDA as factors in step S630 . As described above, the first cipher text COD1 is obtained by encrypting the authenticator (CER) with the user identifier (IDU), and the second cipher text COD2 is obtained by encrypting the first cipher text COD1 with the device identifier (IDA) will be. Here, the third cryptographic function E3 () is the inverse of the second cryptographic function E2 (). In step S630, the controller 260 extracts a third cipher text (COD3) obtained by encrypting the authenticator (CER) with the user identifier (IDU) from the second cipher text (COD2) through the device identifier (IDA). Accordingly, the third cipher text COD3 has the same value as the first cipher text COD1. The third cryptographic function E3 () is, for example, the following Equation (3).

&Quot; (3) "

IDA = COD3, 여기서,

는 XOR 연산자E2 (cod2, ida) = COD2

IDA = COD3,

Is an XOR operator

The second cipher text COD2 is 'COD2 = {0110}' and the third cipher text COD3 (COD2) is '0110' according to the third cryptographic function E3 () in Equation 3 when the device identifier (IDA) ) Becomes 'COD3 = {1010}'.

Then, the controller 260 of the door lock control device 200 transmits the third cipher text 'COD3 = {1010}' to the second user device 302 through the communication module 310 in step S640. Then, in step S650, the control module 350 of the second user device 302 uses the third cipher text 'COD3 = {1010}' and the user identifier (IDU) 'IDU = {1100} (COD4) through the first cipher text (). Here, the fourth cryptographic function E4 () is the inverse of the first cryptographic function E1 (). As described above, the first cipher text COD1 is obtained by encrypting the authenticator (CER) with a user identifier (IDU). The third cipher text (COD3) is also the one obtained by encrypting the authenticator (CER) with the user identifier (IDU), and the third cipher text (COD3) has the same value as the first cipher text (COD1). Here, the fourth cryptographic function E4 () is the inverse of the first cryptographic function E1 (). Therefore, the control unit 450 extracts the fourth cipher text COD4 from the third cipher text COD3 through the user identifier (IDU) in step S650, and the fourth cipher text COD4 has the same value as the authenticator CER . The fourth cryptographic function E4 () is, for example, as shown in Equation (4).

&Quot; (4) "

IDU = COD4, 여기서,

는 XOR 연산자E4 (cod3, idu) = COD3

IDU = COD4,

Is an XOR operator

Here, the third cipher text COD3 is 'COD3 = {1010}', and when the user IDU is 'IDU = {1100}', according to the fourth cryptographic function E4 () (COD4) becomes 'COD4 = {1001}'.

Then, the control module 350 of the second user device 302 transmits the fourth cipher text 'COD4 = {1001}' to the door lock control device 200 through the communication module 310 in step S660. Then, the controller 260 of the door lock control device 200 compares the fourth cipher text (COD4) received in step S670 with the authenticator (CER) stored in the registration procedure (S600) to perform authentication. If the second user equipment 302 is a device registered according to the procedure shown in FIG. 9, the received fourth cipher text (COD4) 'COD4 = {1001}' is stored in the registration procedure according to the procedure described in FIG. It will have the same value as the authenticator (CER) 'CER = {1001}', and the authentication will succeed. However, in the case of an unregistered user device, since the first to fourth cryptographic functions, the authenticator, and the like can not be known, the authentication can not be successful.

Meanwhile, according to an embodiment of the present invention, the control module 350 of the first user device 301 may periodically update the authenticator (CER). That is, steps S540 to S600 may be repeated periodically. More specifically, the control module 350 of the first user device 300 may newly generate an authenticator (CER) having a different value from the authenticator (CER) periodically issued in step S540. The control module 350 of the first user device 301 then generates the first cipher text COD1 by encrypting the authenticator (CER) with the user identifier (IDU) through the first cryptographic function E1 , And generates a second cipher text (COD2) by encrypting the first cipher text (COD1) with the device identifier (IDA) through the second cryptographic function E1 (). The control module 350 of the first user device 301 then transmits the second cipher text COD2 to the second user device 302 via the communication module 310 and transmits the authenticator CER to the door lock control (200). The control module 350 of the second user device 302 newly receiving the second cipher text COD2 updates the second cipher text COD2 previously received with the newly received second cipher text COD2. In addition, the controller 260 of the door lock control device 200 newly receiving the authenticator (CER) updates the authenticator (CER) previously received with the newly received authenticator (CER). In this manner, the authenticator (CER) can be updated periodically to maintain a high level of security. 10, if the second cipher text (COD2) is transmitted through the peer-to-peer local area communication between the first user device 301 and the second user device 302, According to the update procedure, if the second user device 302 is located in a range outside of the short-range communication, the second cipher text COD2 may be transmitted over the network.

According to the present invention, the user can unlock the door lock without any input. Furthermore, since the authentication is performed by exchanging a plurality of ciphertexts between the first user device 301, the second user device 302 and the door lock control device 200 by using the cryptographic function or the like, a high level of security service is provided can do.
