The user terminal 110 or the smart lock device 200 may be connected to the service server 300 via a network and may be connected to a server other than the service server 300 Server) to implement a smart lock system according to an embodiment of the present invention.

FIG. 3 is a flow chart for explaining an authentication information registration procedure of the smart lock device according to an embodiment of the present invention, and FIG. 7 is an exemplary screen shot for explaining the registration procedure of this embodiment.

The user terminal 110 may execute a service application or an augmented reality application provided by the service server 300 (S310). For registration, the terminal registration menu (or setting menu) displayed on the application screen can be selected (S320). For example, as shown in (a) of FIG. 7, after the user executes the application, the terminal registration menu on the upper right can be selected, and as shown in (b) The type of information can be selected. The figure includes authentication information including a pattern and a password, but is not limited thereto, and may include various authentication information such as biometric information including a fingerprint, an iris, and a face.

The user may input authentication information on the user terminal 110 (S330). In one embodiment, when the user selects the pattern as the authentication information, the user can input a pattern to be set as shown in FIG. 7C. In another embodiment, when the user selects the password as authentication information, the user can input the password using the keypad as shown in FIG. 7 (d). The authentication information is set through the user terminal 110. The authentication information is not limited to the numeric keypad of the existing hardware lock device, and various types of passwords such as letters, numbers, special characters, and combinations thereof can be input. Furthermore, as described above, it is possible to input various biometric information.

The user terminal 110 may generate authentication data by encrypting the authentication information when the input of the user is completed. The user terminal 110 may access the smart lock device 200 through short-range wireless communication and transmit the encrypted authentication information and the identification information of the user terminal (e.g., UMEI / IMSI) to the smart lock device 200 S340). Also, the user terminal 110 can transmit a nonce value and anchor value required for authentication. The smart lock device 200 may receive the authentication information and store the authentication information together with the identification information of the user terminal 110. [ After storing the authentication information, the smart lock device 200 may transmit a registration completion message to the user terminal 110 (S350). The user terminal 110 may receive a registration completion message, as shown in Figure 7 (e).

4 is a flowchart illustrating an authentication information changing procedure of the smart lock device according to an embodiment of the present invention. The user can execute the service application or the augmented reality application, select the authentication information change menu in the application menu, or select the authentication information change menu using the augmented reality marker (S410 to S430). In one embodiment, when an augmented reality marker is used, an augmented reality function is executed to scan a registered marker in a photographed image (S420), and an authentication information change menu for the marker can be executed (S430).

After the user terminal 110 selects the authentication information change menu, the user terminal 110 may access the smart lock device 200 to perform user authentication (S440). The user authentication can be performed using the authentication information previously registered in the smart lock device 200 and the authentication information input through the user terminal 110. [ When the user authentication is completed, the user terminal 110 can receive the authentication information to be changed (S450). As described above, the authentication information can be in various forms such as letters, numbers, special characters, a combination thereof, and can input biometric information. When the new authentication information is input, the user terminal 110 transmits the authentication information to the smart lock device 200 and receives the authentication information registration result (S460, S470) similarly to the authentication information registration procedure.

5 is a flowchart illustrating a marker registration procedure of the smart lock device 200 according to an embodiment of the present invention. FIG. 8 shows exemplary screen shots for illustrating the marker registration procedure.

The user terminal 110 may register a marker by executing a service application or an augmented reality application provided by the service server (S510). The user terminal 110 can select a marker registration menu (S520), execute an augmented reality function, and register a marker by photographing an object, a photograph or an image (screen) to be registered as a marker (S530, S540).

8, a marker registration menu can be executed by executing an augmented reality function on the user terminal 110 (Fig. 8 (a), (b)). After the marker registration menu is selected, a photograph to be registered is photographed (FIG. 8 (c)), and the photographed photograph can be registered as a 'marker' (FIG.

As described above, the present invention has an advantage in that a user can easily register, change, and manage a marker for operating the smart lock device in the augmented reality through the marker registration menu. In addition, through the implementation of these functions, the markers can be individually registered and used in the user terminal 110 owned by each user. Furthermore, the security is improved because the other person can not know the marker, and there is an advantage that the additional cost due to marker damage is not generated.

6 is a flowchart illustrating a service method of the smart lock device 200 according to an embodiment of the present invention. The smart lock device 200 and the user terminal 110 may be connected via short-range wireless communication. In one embodiment, the user terminal 110 may be implemented such that when the service application is executed, the local communication module is automatically operated and connected between the devices (S610). The user terminal can execute the service application and operate the augmented reality function to scan previously registered markers (S620). The marker may be a marker directly registered through the user terminal 110 as described with reference to FIG.

When the user terminal 110 scans the marker through the service application and recognizes the smart lock device, it can be guided to enter authentication information. Here, the authentication information may be authentication information directly input through the user terminal 110 as described with reference to FIG. 3, and may be an initial value set by the service application at initial (not yet set). The user can input authentication information through an input module such as a pattern input button, a keypad, a microphone, etc. of the user terminal 110 (S630).

When authentication information is input to the user terminal 110, authentication data is generated (S640). The authentication data can generate the authentication data by encrypting the authentication information value inputted by the user and generating a value for the additional authentication. In one embodiment, the authentication data may be generated as shown in Equation (1) by combining the authentication information value of the user with the IMEI value, which is a unique number of the user terminal, and encrypting the authentication information with a nonce and a hash algorithm. The encrypted authentication data is transmitted to the smart lock device 200 and subjected to a verification process (S650, S660).

Authentication data = Hash (Hash (IMEI + authentication information) + Nonce) - Equation (1)

Here, the Nonce value is a random value generated to differentiate the generated authentication data at each authentication. NextNonce value, which is the next Nonce value, is randomly generated at the time of generating authentication data, and is transmitted together at the time of authentication.

For example, when the initial nonce value is 123 (the first nonce value), the user terminal 110 can generate the authentication data of Equation (1) using the first nonce value. At this time, " 456 " (second nonce value) which is NextNonce value to be used for the next authentication can be randomly generated and transmitted together with authentication data. The smart lock device 200 receives the authentication data and the second nonce value. The smart lock device 200 generates and verifies the authentication information with the first nonce value. If the authentication is successful, the smart lock device 200 transmits the nonce value to the second nonce value (E.g., 456). That is, at the time of the next authentication, the user terminal can generate the authentication data with the second nonce value and generate and transmit the new Next noonce value again. The smart lock device receives the authentication data based on the second nonce value and the new NextNonce value, the smart lock device 200 generates the authentication information with the updated second nonce value, and when the authentication succeeds, the nonce value .

As described above, the authentication data can generate dynamic authentication data by using the Nonce value generated randomly at the time of authentication, and security and stability of the authentication information can be assured.

As another embodiment, anchor value can be used as additional authentication information when verifying authentication data. The anchor value is an additional authentication method used for enhancing authentication security. When authentication is performed, a LastAnchor value and a NextAnchor value are transmitted together to verify whether the anchor value of the smart lock device 200 is the same as the LastAnchor. If the verification succeeds, the anchor value of the smart lock device can be updated to the NextAnchor value.

In one embodiment, anchor values may be generated with date and time values. The LastAnchor value is the last authentication time, and the NextAnchor value can be generated as the current authentication time. The user terminal can transmit the encrypted authentication information and the anchor information together to the smart lock device 200. [ The smart lock device 200 verifies the encrypted authentication information, and further verifies the anchor value upon success. When the authentication is successful, the smart lock device 200 can determine that the final authentication succeeded.

In one embodiment, the initial nonce value and the anchor value may be transmitted to the smart lock device 200 upon terminal registration, and may be updated to a new value each time authentication (i.e., authentication data generation and delivery) occurs.

The smart lock device 200 can transmit a release command to the lock module of the lock device and can release the lock module according to the command upon successful verification of the authentication data. The lock module may be a hardware implemented switchgear. In one embodiment, the control of the smart lock device 200 through the authentication information verification may be performed only at the time of unlocking, or as another embodiment, authentication may be performed at every lock or unlock It can also be implemented.

As described above, according to the lock service according to the embodiment of the present invention, safe and convenient control can be performed through the user terminal 110 and the smart lock device 200, thereby improving user convenience. Also, various authentication information can be set and marker can be registered through the user terminal 110, so that security of authentication information is improved. Further, since the management and control through the user terminal 110 is possible, the maintenance cost is reduced as compared with the mechanical lock device, and the cost due to damage or loss is reduced, so that practicality and expandability can be guaranteed.
