A smart box lock / unlock system 100 according to the present invention includes a sender terminal 110, a receiver terminal 120, a management server 130, a mobile terminal 140, and a smart box 150 .

The sender terminal 110 executes a smart box lock / unlock application (application) and transmits a smart box lock request including sender information and receiver information to the management server 130. To this end, an app (application) for locking / unlocking the smart box is installed. If it is not installed, the sender terminal 110 downloads and installs a smart box lock / unlock application from an app market or a web site. This smart box lock / unlock application is a dedicated application that allows the smart box 150 to lock and unlock using the wireless terminal. When the smart box lock / unlock application is executed according to the input of the sender 10, the sender terminal 110 transmits the lock request of the smart box 150 including the sender information and the receiver information to the management server 130 . Here, the sender information is information on the sender 10 that sends an article using the smart box 150, and the recipient information is information on the recipient 20 that receives the article sent by the sender 10. Such sender information and recipient information may include various information such as, for example, the name of the sender / receiver, the telephone number of the sender / receiver, the location where the article is sent and received, the content of the article, In this embodiment, the sender information and recipient information may be registered in advance through the application and stored in the sender terminal 110, or may be input when the article is sent using the smart box 150. [ In addition, the sender terminal 110 transmits its location information to the management server 130 when the application is executed. Thus, the management server 130 can check the current location of the sender 10 who wants to deliver the current product by checking the location of the sender terminal 110. [

The recipient terminal 120 executes the smart box lock / unlock application and transmits a request for unlocking the smart box containing the recipient information. To this end, an application for locking / unlocking the smart box is also installed in the receiver terminal 120. If it is not installed, you can download it and install it. The receiver terminal 120 transmits an unlock request for the smart box 150 including the receiver information to the management server 130 when the smart box lock / unlock application is executed by the input of the receiver 20. In the present embodiment, recipient information may be registered in the receiver terminal 120 in advance through an application or may be stored in the smart box 150 when the article is received. In addition, when the recipient terminal 120 executes the application, the recipient terminal 120 transmits its own location information to the management server 130. Thus, the management server 130 can determine the current position of the receiver 10 to receive the article by grasping the position of the receiver terminal 110.

When the lock request is received from the sender terminal 110, the management server 130 generates a lock signal including the first cryptographic key and transmits the lock signal to the mobile terminal 140. When the lock request is received from the receiver terminal 120, 2 encryption key and transmits the unlock signal to the mobile terminal 140. The management server 130 is a device that manages the overall product delivery service using the smart box 150. The management server 130 receives a lock request and an unlock request of the smart box 150 from the sender terminal 110 and the receiver terminal 120, A lock signal for locking the smart box 150 and a lock release signal for releasing the lock are generated and transmitted to the mobile terminal 140. In particular, when a lock request is received from the sender terminal 110, a first cryptographic key is generated and included in the lock signal, and then a lock signal is transmitted to the mobile terminal 140. Thereafter, The second cryptographic key is generated and included in the unlock signal, and the unlock signal is transmitted to the mobile terminal 140. The management server 130 also receives the location information from the sender terminal 110 and the receiver terminal 120 and determines the location of the receiver 10 and the receiver 20, respectively.

The mobile terminal 140 is provided in the mobile unit 30 for moving the smart box 150 and transmits a lock signal and an unlock signal received from the management server 130 to the smart box 150. The moving body 130 moves or moves the smart box 150 to the receiver 20 by storing or storing articles to be delivered to the smart box 150 at the request of the sender 10, , A courier, or a quick service article, or a vehicle such as a vehicle, a bicycle, or a motorcycle. Unmanned vehicles and unmanned vehicles moving in unmanned vehicles may also be included in transportation in the future. In addition, the mobile terminal 140 transmits its location information to the management server 130 according to a predetermined period. Thus, the management server 130 periodically grasps the location of the mobile terminal 140. Particularly, it becomes possible to confirm whether the mobile terminal 140 has moved to reach the position of the sender 10 that orders the delivery of the article, and reaches the position of the receiver 20 to receive the article. The management server 130 may transmit the location of the mobile terminal 140, that is, the location of movement of the article, to the sender terminal 110 and the receiver terminal 120 at each cycle. This is so that the sender 10 and the receiver 20 can confirm the delivery position of the article. In FIG. 2, for example, the mobile device 30 is shown as a delivery source. However, the present invention is not limited thereto.

When the lock signal is received from the mobile terminal 140, the smart box 150 stores therein the first cryptographic key included in the received lock signal, performs locking, and then releases the lock from the mobile terminal 140 When the signal is received, the second cryptographic key included in the received unlock signal is compared with the previously stored first cryptographic key, and if it is the same, unlocking is performed. Specifically, the smart box 150 is moved by the moving body 30 and is provided with a space for storing or loading an article to be delivered therein, and can perform locking and unlocking itself for security and safety of the article . For example, the mobile device 30 and the smart box 150 may be integrated. In addition, the smart box 150 performs a lock according to a lock signal of the management server 130 from the mobile terminal 140 and performs unlocking according to the lock release signal. At this time, the first cryptographic key included in the lock signal is stored. When the unlock signal is received, the second cryptographic key included in the unlock signal is compared with the first cryptographic key, and unlocking is performed only when the first cryptographic key is matched . Here, the first cryptographic key and the second cryptographic key are generated in the management server 130 for locking and unlocking the smart box 150. The first cryptographic key and the second cryptographic key are mapped to each other in pairs, and these pairs are used for a single use and are deleted after locking and unlocking of the smart box 150 is performed. When a new lock is requested thereafter, a new first cryptographic key is generated and a new second cryptographic key is generated when an unlock corresponding to the new lock is requested. As described above, in the present invention, the first cipher key and the second cipher key are generated in a one-time use corresponding to a specific pair of lock and unlock, respectively, and the first and second cipher keys generated when the corresponding lock and unlock are completed are deleted .

FIG. 3 is a view illustrating a display for transmitting a lock request of a smart box in a sender terminal according to the present invention, and FIG. 4 is an exemplary view for transmitting a lock box unlock request in a receiver terminal according to the present invention.

Referring to the drawing, when the sender 10 uses the smart box service, the smart box lock / unlock application is executed and the smart box service start button is pressed. Here, the smart box service comprehensively means a locking and unlocking service of the smart box 150 that can be used for security and safety together with a delivery service using the smart box 150. Although not shown in the drawing, a dedicated application can be downloaded and executed to register membership and user information for using the smart box service in advance. When the sender terminal 110 of the sender 10 of the sender 10 sending the goods pushes the smart box service start button, the name of the sender who wants to deliver the goods and the name of the receiver to receive the goods and the telephone number of the receiver The window to enter appears. When the necessary information is inputted, the smart box lock button is displayed. When the corresponding button is pressed, the smart box lock request is transmitted from the sender terminal 110 to the management server 130.

When the receiver terminal 120 of the receiver 20 to receive the goods presses the smart box start button, a window for inputting the receiver name and the receiver's phone number is displayed. When the necessary information is inputted, the smart box unlocking button is displayed Button is pressed, a smart box unlock request is transmitted from the sender terminal 110 to the management server 130.

That is, the sender terminal 110 is the side to deliver the goods and the receiver terminal 120 is the side that receives the goods. Accordingly, the sender terminal 110 transmits a smart box lock request and the receiver terminal 120 transmits a smart box unlock request. Examples of these drawings are for convenience of explanation, and various information may be input in a different form or may be implemented in a different manner.

The locking and unlocking process of the smart box 150 will be described with reference to an example in which the mobile terminal 140 and the smart box 150 move from the sender 10 to the receiver 20 as shown in FIG.

First, the sender 10 uses the sender terminal 110 owned by the sender 10 to execute the application, inputs necessary information, and requests the smart box service. At this time, the necessary information may be registered at the time of membership registration or may be input at the time of service application. The management server 130 informs the mobile terminal 140 of the smart box service request of the sender terminal 110 and transmits the location information of the sender 10 transmitted from the sender terminal 110 to the mobile terminal 140. The mobile terminal 30 searches the sender 10 using the positional information of the sender 10 received at the mobile terminal 140. [

Thereafter, the moving object 30 receives the article from the sender 10 and puts it into the smart box 150. The sender 10 executes the app at the sender terminal 110 to transmit the lock request of the smart box 150 to the management server 130 in order to proceed with locking the smart box 150. [

In response to the lock request, the management server 130 generates a lock signal including the first cryptographic key and transmits the lock signal to the mobile terminal 140, and the mobile terminal 140 transmits the lock signal to the smart box 150 again . When the lock request is received from the sender terminal 110, the management server 130 determines whether the location information of the mobile terminal 140 received from the mobile terminal 140 is identical to the sender information transmitted by the sender terminal 110 And if it is the same, generates a lock signal and transmits it to the mobile terminal 140. This is to transmit a lock signal to the mobile terminal 140 after the management server 130 confirms whether the mobile terminal 140 has correctly visited the location of the sender 10 requesting the smart box service.

The smart box 150 performs locking according to the lock signal and stores the first cryptographic key in an internal memory. When the lock of the smart box 150 is completed, the mobile 140 confirms the completion of the lock of the smart box 150 and informs the management server 130 of the completion of the lock. Then, the mobile terminal 140 inputs (or registers) The recipient 20 is referred to in order to deliver the article based on the received recipient information.

When the mobile device 30 moves to the receiver 20, the recipient 20 executes the application from the receiver terminal 120 to receive the item stored in the smart box 150, and sends an unlock request for the smart box 150 To the management server 130. In response to the unlock request, the management server 130 generates a lock signal including the second cryptographic key and transmits the lock signal to the mobile terminal 140, and the mobile terminal 140 again transmits an unlock signal to the smart box 150 . The management server 130 determines whether the location information of the mobile terminal 140 received from the mobile terminal 140 and the receiver information received from the receiver terminal 120 are the same when receiving an unlock request from the receiver terminal 120 And if it is the same, generates an unlock signal and transmits it to the mobile terminal 140. This is to transmit the unlock signal to the mobile terminal 140 after the management server 130 confirms whether the mobile terminal 140 has correctly located the receiver 20 to receive the goods through the smart box service.

Here, the mobile terminal 140 transmits its location information at a period set in the management server 130, and the management server 130 transmits the location information of the mobile terminal 140 to the sender terminal 110 and the receiver terminal 120 send. Thus, the sender 10 who has applied for the SmartBox service or the recipient 20 to receive the article can know the conveying path of the article.

The mobile terminal 30 receives the article from the sender 10 and inserts the article into the smart box 150 and then searches the receiver 20 together with the smart box 150. If the receiver 20 is absent, To the management server 130, the absence notice information indicating the absence of the recipient 20 to receive the article from the smart box 150. [ For example, the mobile terminal 30 can confirm the absence of the receiver 20 and transmit the absence notification information to the management server 130 through the application of the mobile terminal 140. [ As another example, in the case of the unmanned vehicle, if there is no receiver 20 at the position stored in the receiver information and the unlock request signal is not received from the receiver terminal 120 within a predetermined time, the mobile terminal 140 transmits the unlock request signal to the management server 130 It may be set to automatically transmit notification information.

When the absence notification information is transmitted from the mobile terminal 140 to the management server 130, the management server 130 transmits the notification information to the sender terminal 110. This allows the sender 10 to confirm the absence of the recipient 20. Here, the sender 10 can transmit an unlock request by the sender to the management server 130 through the app of the sender terminal 110. The management server 130 generates an unlock signal including the second encryption key and transmits the unlock signal to the mobile terminal 140 when the unlock request is received from the sender terminal 110 as described above. Accordingly, the mobile terminal 140 transmits it to the smart box 150, and the smart box 150 performs unlocking of the smart box 150 when the second encryption key and the previously stored first encryption key match. This is to enable unlocking of the smart box 150 upon request of the sender 10 when the receiver 20 is not in the requested position.

5 is a configuration diagram of a management server according to the present invention.

5, a management server 130 according to the present invention includes a member subscription unit 131, a member management unit 132, a storage unit 133, a cryptographic key generation unit 134, a signal generation unit 135, A mapping unit 136, a comparison unit 137, a server control unit 138, and a transmission / reception unit 139.

The membership subscription unit 131 processes subscription using various input information input from the sender terminal 110 and the recipient terminal 120 through the application. This membership is intended to be approved as a member to use the Smartbox service through the app. To this end, the membership subscription unit 131 requests information required for subscription to each of the terminals 110 and 120, and performs a membership process using the input information.

The member management unit 132 is for managing registered members, and divides the registered information into a plurality of items. In particular, it shall manage the membership and withdrawal of the member and manage the member's information change.

The storage unit 133 stores various programs for smart box service, information, data, and information of the registered users. For example, not only basic information such as a name, a telephone number, an address, and the like can be stored for each member, but the service usage history and payment history for each member can also be stored.

The encryption key generation unit 134 generates the first encryption key and the second encryption key. The cryptographic key generation unit 134 generates a first cryptographic key when a lock request is received from the sender terminal 110 under the control of a control unit 138 to be described later and receives an unlock signal from the receiver terminal 120 Thereby generating a second cryptographic key. When the first cryptographic key and the second cryptographic key are mapped to each other, they are generated as one-time use for one smart box service. Accordingly, when the delivery through the smart box service is completed between the sender 10 and the recipient 20, the first cryptographic key and the second cryptographic key are deleted and can no longer be used.

The signal generator 135 generates a lock signal and an unlock signal. The signal generator 135 generates a lock signal including the first cryptographic key generated as described above when the lock request is received from the sender terminal 110 under the control of the controller 138, When the unlock signal is received, the unlock signal including the generated second cryptographic key is generated. The lock signal and the unlock signal are used as a signal for locking and unlocking the smart box 150. [

The mapping unit 136 maps the receiver information received from the receiver terminal 120 and the receiver information received from the transmitter terminal 110. This is for confirming which receiver terminal 110 requested the receiver information when the receiver information is received from the receiver terminal 120 when there are a plurality of senders and receivers using the smart box service. That is, it is for mapping information of the receiver 20 requesting reception of the article by the sender 10 and information of the receiver 20 receiving the actual article for one smart box service. This is a very important process for generating the second cryptographic key. This is because it is possible to generate a second cryptographic key that is mapped to the first cryptographic key only if the receiver requesting unlocking confirms which sender is the requested recipient. If the second cryptographic key that is not mapped to the first cryptographic key is generated and transmitted, the smart box 150 fails to unlock. Accordingly, the mapping unit 136 maps the recipient information transmitted from the sender terminal 110 to the recipient information transmitted from the recipient terminal 120, thereby allowing the receiver 20 to unlock the same recipient 20.

The comparing unit 137 compares the location information of the mobile terminal 140 received from the mobile terminal 140 with the location information of the sender 10 among the sender information received from the sender terminal 110. This is for judging whether or not the mobile terminal 140 has moved accurately to the position of the sender 10 requesting the article delivery together with the smart box 150. The comparison unit 137 compares the location information of the mobile terminal 140 received from the mobile terminal 140 with the location information of the receiver 20 among the receiver information received from the transmitter terminal 110. This is for judging whether or not the mobile terminal 140 has moved accurately to the position of the receiver 20 to receive the article to be delivered together with the smart box 150.

The server control unit 138 controls the overall operation of the management server 130.

The transceiver unit 139 is responsible for transmitting and receiving data to and from the transmitter terminal 110, the receiver terminal 120 and the mobile terminal 140 via the communication network 160.

6 is a configuration diagram of a smart box according to the present invention.

6, the smart box 150 includes a communication unit 151, a locking unit 152, a driving unit 153, a memory unit 154, and a control unit 155.

The communication unit 151 performs short-range communication with the wireless terminal. The wireless terminal includes, for example, a mobile terminal 140. The local area communication uses a communication method for performing wireless communication within a predetermined distance from the mobile terminal 130 and can use a communication method such as Bluetooth (BLE), NFC, Zigbee, RFID and the like. In the embodiment of the present invention, an appropriate communication method can be used in consideration of the communication distance, and preferably the BLE communication is used.

The locking part 152 functions to lock and unlock the smart box 150. [ This locking and unlocking means physically closing and opening the smart box 150. This locking portion 152 may include, for example, a lock that can be electronically actuated.

The driving unit 153 drives the operation of the locking unit 153 to lock and unlock the smart box 150. The driving unit 153 may include a driving source such as a motor.

The memory unit 154 stores the encryption key.

The control unit 155 controls the overall operation of the smart box 150. In particular, when the control unit 155 receives the lock signal from the management server 130 through the communication unit 151, the control unit 155 stores the first encryption key included in the lock signal in the memory unit 154, When the unlock signal is received from the management server 130 via the communication unit 155, the second encryption key included in the unlock signal is stored in the memory unit 150. [ And controls the operation of the driving unit 153 to unlock the smart box 150 if the first encryption key stored in the first encryption key 154 matches the first encryption key.

As described above, the smart box 150 according to the present invention receives data through short-range communication with the mobile terminal 140 and performs locking and unlocking operations using the received data.

7 is a flowchart illustrating a method of locking and unlocking a smart box according to an embodiment of the present invention.

Referring to FIG. 7, in the method of locking and unlocking the smart box according to the present invention, the sender terminal 110 first executes an application (application) for locking / unlocking the smart box (S101) (S103), the management server 130 transmits a lock request of the smart box 150 including the sender information of the sender 10 requesting the article delivery and the receiver information of the receiver 20 to receive the article, The server 130 stores the sender information and the receiver information in the memory unit 153 (S105), generates a first encryption key (S107), and generates a lock signal including the generated first encryption key (S109), and transmits a lock signal to the mobile terminal 140 (S111). Here, the mobile terminal 110 transmits its location information to the management server 130 so that the management server 130 always confirms the location of the mobile terminal 140. The management server 130 manages the location of the mobile terminal 140 Confirms arrival of the mobile terminal 140 after checking whether the mobile terminal 140 has arrived at the location of the delivery article, i.e., the location of the sender terminal 110, by checking the location information of the sender 10 among the sender information requested by the sender terminal 110 And transmits the lock signal to the mobile terminal 140.

When the mobile terminal 140 receives the lock signal from the management server 130, the mobile terminal 140 transmits the lock signal to the smart box (S113). Then, the smart box 150 stores the first encryption key included in the lock signal in the memory unit 153 (S115), and locks the smart box 150 according to the lock signal (S117). Thus, the article is safely stored inside the smart box 150.

Thereafter, the mobile 30 moves with the smart box 150 to the position of the receiver 20 to receive the article. For this movement, the management server 130 transmits the sender information and the receiver information received from the sender terminal 110 to the mobile terminal 140. That is, the mobile terminal 140 confirms the location of the receiver 20 by checking the receiver information.

When the mobile terminal 30 moves to the position of the receiver 20, the receiver 20 performs an operation for unlocking the smart box 150 using the receiver terminal 120. Specifically, an application for locking / unlocking the smart box is executed in the receiver terminal 120 (S119), and an unlock request for the smart box 150 including the receiver information of the receiver 20 to receive the article is transmitted to the management server (S121).

The management server 130 maps the recipient information received from the recipient terminal 120 and the recipient information received from the sender terminal 110 as described above (S123), generates a second cryptographic key corresponding to the mapped recipient information S125), generates an unlock signal including the generated second encryption key (S127), and transmits an unlock signal to the mobile terminal 140 (S129). At this time, the second cryptographic key uses the mapped receiver information to generate a second cryptographic key identical to the first cryptographic key when the two recipient information are the same. The smart box 150 generates a second cryptographic key identical to the first cryptographic key when the recipient information requested by the sender 10 and the recipient information requested by the recipient 20 match, And to perform unlocking when the keys are the same.

Subsequently, the mobile terminal 140 transmits the lock release signal received from the management server 130 to the smart box 150 (S131). Then, the smart box 150 compares the second cryptographic key included in the unlock signal with the first cryptographic key stored in the memory unit 153 in step S115 (S133) The unlocking is executed (S135). This allows the recipient 20 to receive goods from the smart box 150.

Although not shown in the drawing, the mobile terminal 140 receives the article from the sender 10, moves to the position of the receiver 20 together with the smart box 150, and transmits the article to the receiver 20 And to transmit various kinds of information to the management server 130. This allows the mobile unit 30 to transmit relevant information to the management server 130 through the mobile terminal 140 for each process. Thus, the management server 130 can grasp various situations occurring in the course of delivering the goods from a remote place. In particular, the location, the movement route, and the like of the smart box 150 can be confirmed.

8 is a flowchart illustrating a method of unlocking a smart box according to another embodiment of the present invention.

8 shows an unlocking method when the moving body 30 moves to the position of the receiver 20 with reference to the receiver information, and the receiver 20 is absent at that position. Since the process of moving the article from the sender 10 to the recipient 20 is the same as that of FIG. 7, the description of the repetitive description will be omitted. Hereinafter, the recipient 20, Will be described hereinafter.

When the mobile unit 30 confirms the absence of the receiver 20 at the arrival position, the mobile unit 30 transmits the absence notification information to the management server 130 (S201). Then, the management server 130 confirms absence of the receiver 20 and transmits the received absence notification information to the sender terminal 110 (S203). At this time, the management server 130 checks the location information of the mobile terminal 140 to determine whether it is the same as the location of the receiver 20 included in the receiver information, and transmits the absence notification information to the transmitter terminal 110 . This is to check first whether the mobile terminal 140 has reached the position of the receiver 20 correctly. If you move to the wrong location due to a mistake or a network error, you can correct the location information and send it.

When the absence notification information is received from the management server 130, the sender terminal 110 transmits an unlock request by the sender (S205). This is to allow the sender 10 to notify the sender 10 of the fact that the receiver 20 is absent and there is no way to open the smart box 150 on the receiver side so that the sender 10 can directly open it. Of course, in another embodiment, the absence of the recipient 20 may allow a family member, friend, or the like to be opened using his / her terminal. In order to do so, the sender terminal 110 may input information of a family member or a friend to the management server 130, and may transmit the unlock request to a family member or a friend via a certain authentication procedure.

Thereafter, the management server 130 generates a second cryptographic key when the sender terminal 110 receives an unlock request from the sender (S207), generates an unlock signal including the generated second cryptographic key (S209) and transmits an unlock signal to the mobile terminal 140 (S211). At this time, the management server 130 generates a second cryptographic key identical to the first cryptographic key generated according to the lock request received from the sender terminal 110 upon receipt of the lock release request. This is because if the first cipher key and the second cipher key are the same in the smart box 150, unlocking is performed, and since the same sender 10 is requested to lock and unlock it, unlocking is performed by generating the same cipher key Because.

In this manner, the mobile terminal 140 transfers the unlock signal received from the management server 130 to the smart box 150 (S213). The smart box 150 compares the second cryptographic key included in the unlock signal with the first cryptographic key stored in the memory unit 153 in step S215. If the same is true, the smart box 150 cancels the unlocking of the smart box 150 (S217). This case can be used when the recipient 20 is absent to allow the delivery of the article to another person.

As described above, in the smart box lock / unlock system and method according to the present invention, the sender 10 to send an article and the receiver 20 to receive an article are respectively connected to a smart box The management server 130 requests the management server 130 of the remote site to lock and unlock the smart box 150 and the mobile terminal 140 of the mobile terminal 30 that moves the smart box 150 according to the request So that the smart box 150 can perform locking and unlocking on its own by transmitting a lock signal and an unlock signal to the smart box 50 via the communication link. This is very safe and secure because only the sender and the recipient request the lock and unlock of the smartbox directly using the registered information. In addition, in the case where the receiver is absent, since the sender who is not the third party directly requests the unlocking, safety and security can be maintained.
