     In a first aspect of the embodiments of the present disclosure, there is proposed an electronic distribution method, which may improve the confidentiality of distribution to a certain extent. 
     As shown in  FIG. 1 , the electronic distribution method is applied to an electronic distribution apparatus, which specifically is, for example, an electronic distribution box for placing an item to be distributed. The electronic distribution method comprises the following steps. 
     In step  11 , user information and first terminal information of a distribution terminal which are transmitted by a server are acquired. 
     In an embodiment, when a user needs to use a distribution service, the user initiates a distribution request to the server through a user terminal, wherein the distribution request generally comprises the user information; and when the server receives the distribution request, the server generates a distribution task, determines an electronic distribution apparatus and a distribution terminal, and issues the distribution task to the distribution terminal, so that the server acquires first terminal information of the distribution terminal. Then, the server transmits the user information and the first terminal information of the distribution terminal to the electronic distribution apparatus to be stored by the electronic distribution apparatus for subsequent display and identity verification. 
     The electronic distribution apparatus is connected with the server using a Narrow Band Internet of Things (NB-IoT) timing. When the electronic distribution apparatus is connected with the server, the server forwards first terminal information of the selected distribution terminal to the electronic distribution apparatus to be stored by the electronic distribution apparatus. 
     In an embodiment, the user terminal and the distribution terminal may be mobile terminals, and data interaction between the user terminal and the server and data interaction between the distribution terminal and the server may be implemented by APPs of the mobile terminals. 
     In an embodiment, when the distribution terminal is a mobile terminal, the server may transmit the distribution task to the distribution terminal by using a short message, the distribution terminal receives the corresponding information, for example, an ID of the electronic distribution apparatus, by starting an APP, and at the same time, the APP may automatically transmit first terminal information of the distribution terminal to the server by acquiring the first terminal information in the background. 
     In an embodiment, when the distribution terminal is used by a dispatcher, the dispatcher also needs to log in to the APP by using a password. 
     In an embodiment, the first terminal information of the distribution terminal comprises a Bluetooth Media Access Control (MAC) address and/or a Near Field Communication (NFC) chip Identity (ID) of the distribution terminal which is stored by the server, and when data interaction is performed between the distribution terminal and the electronic distribution apparatus, the information of the distribution terminal may be read through Bluetooth and NFC, to perform identity verification, thereby greatly improving efficiency of the data interaction. In an embodiment, the user information mainly comprises content such as a username/name, an address, contact information, etc. of the user. 
     In step  12 , a first key is generated and the first key is transmitted to the server. 
     In an embodiment, after the electronic distribution apparatus receives the user information and the first terminal information of the distribution terminal, the electronic distribution apparatus generates the first key and forwards the first key to the distribution terminal through the server. In this way, before interaction is subsequently performed between the distribution terminal and the electronic distribution apparatus, the distribution terminal firstly encrypts the terminal information thereof by using the first key and then transmits the encrypted terminal information to the electronic distribution apparatus, so that the interaction process is in an encrypted state, which improves the confidentiality of the distribution. 
     In an embodiment, after the preliminary data interaction (data reception, key generation, etc.) is completed, an item to be distributed is placed in the electronic distribution apparatus, and then the electronic distribution apparatus is locked, and may not be unlocked until the user passes the identity verification when the user receives the electronic distribution apparatus. 
     In step  13 , second terminal information which is encrypted by using the first key and is transmitted by the distribution terminal is acquired. 
     In an embodiment, after the dispatcher finds the electronic distribution apparatus, the dispatcher interacts with the electronic distribution apparatus through the distribution terminal, and transmits the second terminal information encrypted by using the first key to the electronic distribution apparatus, to be used by the electronic distribution apparatus to perform identity verification of the distribution terminal. 
     In an embodiment, if the dispatcher performs identity verification using an APP, the dispatcher needs to log in again through a password to prevent a case where the mobile phone is stolen by others. 
     In an embodiment, the second terminal information comprises a Bluetooth MAC address and/or an NFC chip ID stored by the distribution terminal. If the distribution terminal accesses the electronic distribution apparatus in an NFC P2P mode, the dispatcher selects NFC communication in the APP, and the APP encrypts the Bluetooth MAC address and the NFC chip ID using the key and then transmits the encrypted Bluetooth MAC address and NFC chip ID to the electronic distribution apparatus; and if the distribution terminal accesses the electronic distribution apparatus in a Bluetooth Low Energy (BLE) mode (for example, the distribution terminal does not support NFC), the distribution terminal needs to firstly activate BLE Bluetooth broadcast of the electronic distribution apparatus by pressing a button, then selects to scan and be connected to the electronic distribution apparatus in a Bluetooth mode in the APP, and then encrypts the Bluetooth MAC address and the NFC chip ID using the key and then transmits the encrypted Bluetooth MAC address and NFC chip ID to the electronic distribution apparatus. 
     In step  14 , the second terminal information encrypted by using the first key is decrypted to obtain the second terminal information. 
     In step  15 , the second terminal information is matched with the first terminal information. 
     In step  16 , the user information is displayed if the second terminal information matches the first terminal information. 
     In an embodiment, after the electronic distribution apparatus obtains the second terminal information through decryption, if the second terminal information is consistent with the first terminal information stored by the electronic distribution apparatus, binding with the distribution terminal is completed, and the user information is displayed by a display apparatus (which may be, for example, an electronic paper attached on an outer surface of the electronic distribution apparatus). 
     In an embodiment, if the second terminal information does not match the first terminal information, no information is displayed. 
     The electronic distribution method further comprises step  17  of displaying the user information until a preset time threshold expires, for example, keeping the display of the user information for 30 seconds and then refreshing the display screen to blank. In this way, the display duration of the user information is limited, to prevent other unrelated persons from viewing the user information, which improves the confidentiality of the user information. 
     So far, the electronic distribution apparatus completes the binding with the distribution terminal, the electronic distribution apparatus does not display any user information during subsequent transportation, only the dispatcher knows the user information, and if the dispatcher needs to refer to the user information again, the dispatcher needs to perform the above password log-in, NFC or BLE access processes again, so that the display screen may display the user information again. 
     It may be seen from the above embodiment that in the electronic distribution method according to the embodiment of the present disclosure, firstly, user information and first terminal information of the distribution terminal which are transmitted by the server are received; a first key is generated to be used by the distribution terminal to encrypt the terminal information thereof; after the encrypted terminal information transmitted by the distribution terminal is received, the encrypted terminal information is decrypted and is matched with the terminal information transmitted by the server; and when the matching is successful, the user information is displayed for the dispatcher to view. In this way, both key encryption and information matching are performed, so that the confidentiality of the user information is ensured, and only the dispatcher who passes the identity verification may view the user information, thereby improving the confidentiality of the distribution. 
     As an embodiment of the present disclosure, as shown in  FIG. 2 , the electronic distribution method further comprises the following steps. 
     In step  21 , a delivery command transmitted by the distribution terminal is received, wherein the delivery command comprises the second terminal information encrypted by using the first key. 
     In an embodiment, when the dispatcher delivers the electronic distribution apparatus containing an item to be delivered to the user for delivery, the delivery process needs to be initiated by the delivery command, and identity verification of the distribution terminal of the dispatcher also needs to be performed in the delivery process again, that is, the distribution terminal transmits the delivery command to the electronic distribution apparatus, wherein the delivery command comprises second terminal information encrypted by using the first key, and the second terminal information is used for the identity verification. 
     In an embodiment, before the dispatcher transmits the delivery command using the distribution terminal, the dispatcher also needs to log in to the APP through the password again to improve confidentiality. 
     In step  22 , the second terminal information encrypted by using the first key is decrypted to obtain the second terminal information. 
     In step  23 , the second terminal information is matched with the first terminal information. 
     In step  24 , delivery is performed if the second terminal information matches the first terminal information, and the electronic distribution apparatus enters a state of waiting for confirmation by the customer. 
     In this way, at the time of delivery, both key encryption/decryption and information matching of the distribution terminal are performed again to complete the delivery, which improves the confidentiality of the delivery process. 
     As an embodiment of the present disclosure, as shown in  FIG. 3 , the electronic distribution method further comprises the following steps. 
     In step  31 , third terminal information of the user terminal transmitted by the server is acquired. 
     In an embodiment, when the user initiates a delivery service to the server through the user terminal, the user terminal may automatically transmit the user information and third terminal information of the user terminal to the server. The third terminal information comprises a Bluetooth MAC address and/or an NFC chip ID of the user terminal stored by the server. After the server determines a corresponding electronic distribution apparatus, the server may transmit the user information and the third terminal information of the user terminal to the electronic distribution apparatus to be stored by the electronic distribution apparatus for subsequent identity verification. 
     In step  32 , a second key is generated and the second key is transmitted to the server. 
     In an embodiment, after the electronic distribution apparatus receives the third terminal information of the user terminal, the electronic distribution apparatus generates a second key and forwards the second key to the user terminal through the server, so that before the user terminal subsequently interacts with the electronic distribution apparatus, the user terminal firstly encrypts the terminal information thereof by using the second key and then transmits the encrypted terminal information to the electronic distribution apparatus. In this way, the interaction process is in an encrypted state, which improves the confidentiality of the delivery. 
     In step  33 , fourth terminal information which is encrypted by using the second key and is transmitted by the user terminal is acquired. 
     In an embodiment, after the user receives the electronic distribution apparatus, the user interacts with the electronic distribution apparatus through the user terminal, and transmits fourth terminal information encrypted by using the second key to the electronic distribution apparatus, to be used by the electronic distribution apparatus to perform identity verification of the user. 
     If the user performs identity verification using an APP, the user needs to log in using a password to prevent a case where the mobile phone has been stolen by others. 
     If the user terminal accesses the electronic distribution apparatus in an NFC P2P mode, the user selects NFC communication in the APP, and the APP encrypts the Bluetooth MAC address and the NFC chip ID using the key and transmits the encrypted Bluetooth MAC address and NFC chip ID to the electronic distribution apparatus; and if the user terminal accesses the electronic distribution apparatus in a Bluetooth Low Energy (BLE) mode (for example, the distribution terminal does not support NFC), the user terminal needs to firstly activate BLE Bluetooth broadcast of the electronic distribution apparatus by pressing a button, then selects to scan and be connected to the electronic distribution apparatus in a Bluetooth mode in the APP, and then encrypts the Bluetooth MAC address and NFC chip ID using the key and then transmits the encrypted Bluetooth MAC address and NFC chip ID to the electronic distribution apparatus. 
     In step  34 , the fourth terminal information encrypted by using the second key is decrypted to obtain the fourth terminal information. The fourth terminal information comprises a Bluetooth MAC address and/or an NFC chip ID stored by the user terminal. 
     In step  35 , the fourth terminal information is matched with the third terminal information. 
     In step  36 , if the fourth terminal information matches the third terminal information, which indicates that the user has passed the identity authentication, a locking apparatus of the electronic distribution apparatus is unlocked, and the user takes out the item from the electronic distribution apparatus to complete the delivery. 
     In this way, when the user turns on the electronic distribution apparatus, both encryption/decryption using the second key and information matching of the user terminal are performed to complete the unlocking of the locking apparatus, and only the user who passes the identity verification may turn on the electronic distribution apparatus, thereby improving the confidentiality of the delivery. 
     As an embodiment of the present disclosure, the electronic distribution method further comprises: 
     transmitting the message that the distribution is completed to the server to notify the server that the distribution has been completed, thereby completing the distribution process. 
     In an embodiment, the electronic distribution apparatus transmits the message that the distribution is completed to the server through NB-IoT, the server stores the order, and the distribution task is completed. 
     If the electronic distribution apparatus is lost during the transportation process, as an embodiment of the present disclosure, the electronic distribution method further comprises: 
     receiving a position reporting command transmitted by the server, i.e., receiving a position reporting command issued by the server when the electronic distribution apparatus is connected with the server through NB-IoT; and acquiring positioning information and reporting the positioning information to the server, wherein the positioning information is GPS information, i.e., when receiving the position reporting command, the electronic distribution apparatus turning on a GPS power supply, acquiring the positioning information, and then transmitting the positioning information to the server. 
     In this way, by setting the positioning function, when the electronic distribution apparatus is lost, the positioning information is reported for positioning and searching, so that the electronic distribution apparatus may be efficiently retrieved. 
     It may be seen from the above embodiments and arrangement and combination of the embodiments that the distribution method combining the NB-IoT, NFC and GPS technologies according to the embodiments of the present disclosure effectively solves the confidentiality problem of distribution, and has characteristics such as good confidentiality, high security, capability of being positioned in a case of loss, simple system structure, low cost, low power consumption, easy to use, etc. The electronic distribution method according to the embodiments of the present disclosure effectively solves the problem that the confidentiality of the user information is poor and easy to leak in the conventional express delivery distribution process, and may perform accurate positioning in a case of loss. The method may not only guide the dispatcher to deliver the item to the user, but also may effectively protect the user information from being leaked or illegally stolen in the entire transportation process, which realizes highly secure transmission and delivery of items while ensuring ease of use, and may realize reporting of positioning through a wireless system for easy retrieval if the electronic distribution apparatus is lost. 
     In a second aspect of the embodiments of the present disclosure, there is proposed an electronic distribution apparatus, which may improve the confidentiality of distribution to a certain extent.

When the server receives the distribution request, the server generates a distribution task, determines an electronic distribution apparatus and a distribution terminal, and issues the distribution task to the distribution terminal, so that the server acquires first terminal information of the distribution terminal. Then, the server transmits the user information and the first terminal information of the distribution terminal to the electronic distribution apparatus to be stored by the electronic distribution apparatus for subsequent display and identity verification. 
     In an embodiment, the electronic distribution apparatus is connected with the server using a Narrow Band Internet of Things (NB-IoT) timing. When the electronic distribution apparatus is connected with the server, the server forwards first terminal information of the selected distribution terminal to the electronic distribution apparatus to be stored by the electronic distribution apparatus. Therefore, as shown in  FIG. 5 , the acquisition module  401  may comprise an NB-IoT module configured to interact with the server.

The user information may comprise, for example, content such as a username/name, an address, contact information, etc. of the user. 
     In an embodiment, after the dispatcher finds the electronic distribution apparatus, the dispatcher interacts with the electronic distribution apparatus through the distribution terminal, and transmits the second terminal information encrypted by using the first key to the electronic distribution apparatus, to be used by the electronic distribution apparatus to perform identity verification of the distribution terminal. 
     In an embodiment, the second terminal information comprises a Bluetooth MAC address and/or an NFC chip ID stored by the distribution terminal. If the distribution terminal accesses the electronic distribution apparatus in an NFC P2P mode, the dispatcher selects NFC communication in the APP, and the APP encrypts the Bluetooth MAC address and the NFC chip ID using the key and then transmits the encrypted Bluetooth MAC address and NFC chip ID to the electronic distribution apparatus; and if the distribution terminal accesses the electronic distribution apparatus in a Bluetooth Low Energy (BLE) mode (for example, the distribution terminal does not support NFC), the distribution terminal needs to firstly activate BLE Bluetooth broadcast of the electronic distribution apparatus by pressing a button (fore example, a button as shown in  FIG. 5 ), then selects to scan and be connected to the electronic distribution apparatus in a Bluetooth mode in the APP, and then encrypts the Bluetooth MAC address and the NFC chip ID using the key and then transmits the encrypted Bluetooth MAC address and NFC chip ID to the electronic distribution apparatus. 
     The key generation module  402  is configured to generate the first key and transmit the first key to the server. 
     In an embodiment, after the electronic distribution apparatus receives the user information and the first terminal information of the distribution terminal, the electronic distribution apparatus generates the first key and forwards the first key to the distribution terminal through the server. In this way, before interaction is subsequently performed between the distribution terminal and the electronic distribution apparatus, the distribution terminal firstly encrypts the terminal information thereof by using the first key and then transmits the encrypted terminal information to the electronic distribution apparatus, so that the interaction process is in an encrypted state, which improves the confidentiality of the distribution. 
     The decryption module  403  is configured to decrypt the second terminal information encrypted by using the first key to obtain the second terminal information. 
     The matching module  404  is configured to match the second terminal information with the first terminal information.

     The display module  405  is configured to display the user information if the second terminal information matches the first terminal information. 
     In an embodiment, after the electronic distribution apparatus obtains the second terminal information through decryption, if the second terminal information is consistent with the first terminal information stored by the electronic distribution apparatus, binding with the distribution terminal is completed, and the user information is displayed by a display apparatus (which may be, for example, an electronic paper attached on an outer surface of the electronic distribution apparatus).

     As an embodiment of the present disclosure, the acquisition module  401  is configured to acquire third terminal information of the user terminal transmitted by the server, and acquire fourth terminal information which is encrypted by using a second key and is transmitted by the user terminal. 
     In an embodiment, when the user initiates a delivery service to the server through the user terminal, the user terminal may automatically transmit the user information and third terminal information of the user terminal to the server. The third terminal information comprises a Bluetooth MAC address and/or an NFC chip ID of the user terminal stored by the server. After the server determines a corresponding electronic distribution apparatus, the server may transmit the user information and the third terminal information of the user terminal to the electronic distribution apparatus to be stored by the electronic distribution apparatus for subsequent identity verification. 
     In an embodiment, after the user receives the electronic distribution apparatus, the user interacts with the electronic distribution apparatus through the user terminal, and transmits fourth terminal information encrypted by using the second key to the electronic distribution apparatus, to be used by the electronic distribution apparatus to perform identity verification of the user. 
     In an embodiment, the fourth terminal information comprises a Bluetooth MAC address and/or an NFC chip ID stored by the user terminal. 
     In an embodiment, if the user performs identity verification using an APP, the user needs to log in using a password to prevent a case where the mobile phone has been stolen by others. If the user terminal accesses the electronic distribution apparatus in an NFC P2P mode, the user selects NFC communication in the APP, and the APP encrypts the Bluetooth MAC address and the NFC chip ID using the key and transmits the encrypted Bluetooth MAC address and NFC chip ID to the electronic distribution apparatus; and if the user terminal accesses the electronic distribution apparatus in a Bluetooth Low Energy (BLE) mode (for example, the distribution terminal does not support NFC), the user terminal needs to firstly activate BLE Bluetooth broadcast of the electronic distribution apparatus by pressing a button, then selects to scan and be connected to the electronic distribution apparatus in a Bluetooth mode in the APP, and then encrypts the Bluetooth MAC address and NFC chip ID using the key and then transmits the encrypted Bluetooth MAC address and NFC chip ID to the electronic distribution apparatus. 
     The key generation module  402  is configured to generate the second key and transmit the second key to the server. 
     In an embodiment, after the electronic distribution apparatus receives the third terminal information of the user terminal, the electronic distribution apparatus generates the second key and forwards the second key to the user terminal through the server, so that before the user terminal subsequently interacts with the electronic distribution apparatus, the user terminal firstly encrypts the terminal information thereof by using the second key and then transmits the encrypted terminal information to the electronic distribution apparatus. In this way, the interaction process is in an encrypted state, which improves the confidentiality of the delivery. 
     The decryption module  403  is configured to decrypt the fourth terminal information encrypted by using the second key to obtain the fourth terminal information. 
     The matching module  404  is configured to match the fourth terminal information with the third terminal information. 
     The electronic distribution apparatus further comprises a locking module  408 , configured to, if the fourth terminal information successfully matches the third terminal information, unlock the electronic distribution apparatus, and cause the user to take out the item to complete the delivery. As shown in  FIG. 5 , the electronic distribution apparatus may comprise a motor driver and a case lock, wherein the motor driver is controlled by the processor to drive the case lock to be turned on and turned off. 
     In this way, when the user turns on the electronic distribution apparatus, both encryption/decryption using the second key and information matching of the user terminal are performed to complete the unlocking of the electronic distribution apparatus, and only the user who passes the identity verification may turn on the electronic distribution apparatus, thereby improving the confidentiality of the delivery. 
     As an embodiment of the present disclosure, the electronic distribution apparatus further comprises: an information transmission module  409  configured to transmit the message that the distribution is completed to the server to notify the server that the distribution has been completed, thereby completing the distribution process. 
     In an embodiment, the electronic distribution apparatus transmits the message that the distribution is completed to the server through NB-IoT, the server stores the order, and the distribution task is completed. 
     If the electronic distribution apparatus is lost during the transportation process, as an embodiment of the present disclosure, the command reception module  406  is configured to receive a position reporting command transmitted by the server. 
     The electronic distribution apparatus further comprises a positioning module  410  configured to acquire positioning information. As shown in  FIG. 5 , the positioning module  410  may be a GPS module, and when the electronic distribution apparatus is lost, the server may wake up the GPS module to report a position through NB-IoT. In an embodiment, the positioning information is GPS information, and when the electronic distribution apparatus receives the position reporting command, the electronic distribution apparatus turns on a GPS power supply, acquires the positioning information, and then transmits the positioning information to the server. 
     The information transmission module  409  is configured to report the positioning information to the server. 
     In this way, by setting the positioning function, when the electronic distribution apparatus is lost, the positioning information is reported for positioning and searching, so that the electronic distribution apparatus may be efficiently retrieved. 
     It may be seen from the above embodiments and arrangement and combination of the embodiments that the electronic distribution apparatus combining the NB-IoT, NFC and GPS technologies according to the embodiments of the present disclosure effectively solves the confidentiality problem of distribution, and has characteristics such as good confidentiality, high security, capability of being positioned in a case of loss, simple system structure, low cost, low power consumption, easy to use, etc. The electronic distribution apparatus according to the embodiments of the present disclosure effectively solves the problem that the confidentiality of the user information is poor and easy to leak in the conventional distribution process, and may perform accurate positioning in a case of loss. The method may not only guide the dispatcher to deliver the item to the user, but also may effectively protect the user information from being leaked or illegally stolen in the entire transportation process, which realizes highly secure transmission and delivery of items while ensuring ease of use, and may realize reporting of positioning through a wireless system for easy retrieval if the electronic distribution apparatus is lost. 
     In an embodiment, the electronic distribution apparatus is an electronic distribution box for placing an item to be distributed, and at the same time may also enable data interaction with the user terminal, the distribution terminal, and the server. 
     The electronic distribution box does not have a large data throughput, and does not have a high requirement for performance. From the perspective of low cost and functionality, the BLE SoC (such as a TI CC2541 chip etc.) may be selected, which may not only realize a Micro Control Unit (MCU) master control function, but also support BLE. At the same time, the chip may comprise an Advanced Encryption Standard (AES)  128  encryption and decryption hardware unit to realize subsequent encryption and decryption of NFC P2P data for transmission. The NB-IoT function may be used to perform data interaction with the BLE SoC through a Universal Asynchronous Receiver/Transmitter (UART) port using a module. The NFC P2P function may be implemented by NXP&#39;s PN532 chip, which performs data interaction with BLE SoC via a Serial Peripheral Interface (SPI) interface. The GPS module may perform data interaction with the BLE SoC through a serial port, and its power supply is controlled by a Metal-Oxide Semiconductor Field Effect Transistor (MOSFET) to facilitate control of power consumption. A screen of the electronic paper is used to display customer information, including a name, a phone number, an address, etc. of the customer, and may be connected to the BLE SoC via the SPI interface which is multiplexed with the NFC chip. A switch of a box lock of the distribution box is controlled by a motor driving chip, and the BLE SoC realizes the switch of the box lock through an I/O pulse. The button is used to manually activate BLE of the electronic distribution box to start working. 
     As shown in  FIG. 5 , the electronic distribution box further has a power supply circuit configured to power and charge the electronic distribution box, and mainly comprises a MicroUSB, a charging unit, a lithium ion battery, a Low Dropout Regulator (LDO), a first diode D 1  and a second diode D 2 . 
     The electronic distribution box realized by the above solution has advantages such as a simple circuit structure, a low cost of materials and PCB, and simultaneous support for multiple wireless communication protocols, and meets the requirements of convenient use and intelligent confidentiality of the distribution box; at the same time, its operating mode and software design ensure that the system has very low dynamic and static power consumption, and has a long lifetime.
