In current consumer electronics products with wireless communication, bluetooth communication is one of the common and common communication methods. The Bluetooth communication can be used for wireless communication and transmission among a plurality of electronic products including mobile phones, PDAs, tablet computers, wireless earphones, wireless sound boxes, intelligent watches and the like. Generally, when two bluetooth devices are paired, one bluetooth device searches for the other bluetooth device first, and the two bluetooth devices need to input the same identification code through pairing to establish a connection. However, some bluetooth electronic products do not need identification codes, and when the bluetooth device searches for the bluetooth electronic product, the bluetooth electronic product and the bluetooth electronic product can be connected. Therefore, except that the owner of the bluetooth electronic product can establish a connection with the bluetooth electronic product through the own mobile device (such as a mobile phone), all other mobile devices can search for the bluetooth electronic product and establish a connection, so that the bluetooth electronic product is used by being connected with an unknown mobile device, and the security is further reduced.
In addition, due to the improvement of life quality, the functions and the demands of people on the Bluetooth electronic products are higher and higher, so that the price of the Bluetooth electronic products is also increased. Further, due to the miniaturization trend of electronic products, bluetooth electronic products are easily lost or stolen. Although some bluetooth electronic products have identification codes, users of other mobile devices still have many ways (e.g., password cracking, resetting, etc.) to obtain the identification codes of the bluetooth electronic products, which substantially reduces security.
Therefore, it is necessary to develop a new method for binding bluetooth devices to improve security, so as to solve the problems of the prior art.

Please refer to fig. 1. Fig. 1 is a flowchart illustrating steps of a method for binding bluetooth devices according to an embodiment of the present invention. As shown in fig. 1, the method for binding bluetooth devices of the present invention is used for binding at least one mobile device to a bluetooth device. The method for binding the Bluetooth device comprises the following steps: step S1: the first mobile device obtains a private key of the Bluetooth device; step S2: the first mobile device sends a first connection request to the Bluetooth device, wherein the first connection request comprises first mobile device data and a private key; step S3: the Bluetooth device confirms whether the private key is matched with the public key stored in the Bluetooth device; if the confirmation result of the step S3 is yes, execute step S4: the Bluetooth device judges whether a white list stored in the Bluetooth device contains first mobile device data or not; if the determination result in the step S4 is yes, execute step S5: the Bluetooth device establishes a connection with the first mobile device.
In practice, the mobile device may be a smart phone, a tablet computer, or the like, and the bluetooth device may be a wireless bluetooth headset, a smart watch, a wireless stereo, or other electronic products that need to be bound. Further, the mobile device and the bluetooth device can communicate and transmit data through an application program (APP) in a wireless transmission manner. An Application (APP) may be used to control the bluetooth device and the Application (APP) may be downloaded or imported to be installed in the mobile device. After the mobile device installs the application program (APP) and binds the Bluetooth device, the user can control the Bluetooth device through the application program (APP).
In practice, the bluetooth device may store a pair of public key and private key matching with each other, and the first mobile device may obtain the private key of the bluetooth device through the application program in step S1. Taking a wireless bluetooth headset as an example, the public key is stored in the wireless bluetooth headset, the private key may be attached to a product outer box of the wireless bluetooth headset in an accessory form (such as a sticker, a small card), and the private key may be presented in a QR Code (QR Code). Therefore, the first mobile device can scan the QR code through an Application (APP) to obtain the private key of the wireless bluetooth headset. Please note that, the form and the presentation manner of the private key are not limited thereto, and the manner of obtaining the private key by the first mobile device is not limited thereto. The first mobile device can also input the product serial number of the Bluetooth device through the network to obtain the private key of the Bluetooth device.
After the first mobile device obtains the private key of the bluetooth device, in step S2, the first mobile device transmits the first mobile device data and the private key to the bluetooth device as a first connection request to bind and connect with the bluetooth device. In practice, the first Mobile device data may be a Media Access Control Address (MAC Address) of the first Mobile device, but is not limited thereto, and the first Mobile device data may also be a serial number of the Mobile device, an International Mobile Equipment Identity (IMEI) or other unique Mobile device data. The connection request may also be in the form of a packet, and the first mobile device may store the first mobile device data and the private key in the packet and transmit the packet to the bluetooth device.
After the bluetooth device receives the first connection request sent by the first mobile device, in step S3, the bluetooth device first determines whether the private key and the public key transmitted by the first mobile device are matched. If the private key transmitted by the first mobile device matches the public key of the bluetooth device, it indicates that the bluetooth device accepts the connection request sent by the first mobile device, and then the step S4 is executed.
In practice, the white list of the bluetooth device may be a connection protocol and may store the MAC address, and the bluetooth device may connect with the mobile device corresponding to the MAC address according to the MAC address in the white list. If the determination result in the step S4 is yes, that is, the white list of the bluetooth device includes the first mobile device data, then step S5 is executed: the Bluetooth device establishes a connection with the first mobile device. Therefore, the method for binding the Bluetooth device of the invention takes the public and private keys of the Bluetooth device and the MAC address of the mobile device as the judgment basis for the connection between the Bluetooth device and the mobile device, so as to bind the mobile device to the Bluetooth device.
Further, in step S3, if the private key transmitted by the first mobile device does not match the public key of the bluetooth device, step S31 is executed: the bluetooth device refuses to connect. In practice, when the private key transmitted by the first mobile device does not conform to the public key of the bluetooth device, it indicates that the private key stored in the first mobile device is not the private key of the bluetooth device. At this time, the bluetooth device does not accept the connection request sent by the first mobile device and rejects the connection of the first mobile device. Therefore, the method for binding the Bluetooth device can prevent other mobile devices from being randomly connected with the Bluetooth device through the authentication mechanism of the public key and the private key of the Bluetooth device, so as to improve the safety.
In this embodiment, in step S4, if the data in the white list of the bluetooth device does not include the first mobile device data of the first mobile device, step S6 is executed: the bluetooth device determines whether the white list is blank. If the determination result in the step S6 is yes, execute step S7: the Bluetooth device writes the data of the first mobile device into a white list and establishes a connection with the first mobile device. In practice, when the white list of the bluetooth device is blank, it indicates that the bluetooth device has not established a connection with any mobile device. That is, when the white list of the bluetooth device is blank and the bluetooth device receives the first connection request transmitted by the first mobile device, the first connection request is the connection request received by the bluetooth device for the first time. At this time, the bluetooth device writes the first mobile device data in the first connection request into the white list. Further, since the white list of the bluetooth device includes the first mobile device data of the first mobile device, the bluetooth device also establishes a connection with the first mobile device. Therefore, when the user purchases the bluetooth device and connects the mobile device with the bluetooth device for the first time, the bluetooth device can automatically take the mobile device of the user as the main connection device and bind the mobile device to the bluetooth device.
In addition, in step S6, if the white list is not blank, step S61 is executed: the bluetooth device does not allow the first mobile device to be wired. When the white list of the Bluetooth device is not blank, the Bluetooth device is indicated to be connected with other mobile devices. At this time, the bluetooth device connects to the mobile device for the mobile device data according to the mobile device data in the white list. Thus, when the white list of the bluetooth device is not blank and the data in the white list does not include the first mobile device data of the first mobile device, the bluetooth device rejects the connection of the first mobile device. In practice, when the bluetooth device is stolen or lost and another mobile device intends to connect with the bluetooth device, the other mobile device is not the device connected with the bluetooth device for the first time and the mobile device data of the other mobile device is not in the white list, so that the other mobile device cannot be connected with the bluetooth device, thereby reducing the risk of theft of the product and improving the security.
The method for binding the Bluetooth device can be used for binding the Bluetooth device by a single mobile device, and can also be used for binding one Bluetooth device by a plurality of mobile devices. Please refer to fig. 2. Fig. 2 is a flowchart illustrating steps of a method for binding bluetooth devices according to an embodiment of the present invention. Please note that, in the present embodiment, the first mobile device has bound the bluetooth device through the steps of fig. 1. Further, as shown in fig. 2, the method for binding bluetooth devices comprises the following steps: step S8: the first mobile device obtains second mobile device data of the second mobile device and transmits a private key of the Bluetooth device to the second mobile device; step S9: the first mobile device writes the data of the second mobile device into a white list of the Bluetooth device; step S10: the second mobile device sends a second connection request to the Bluetooth device, wherein the second connection request comprises second mobile device data and a private key; and step S11: and the Bluetooth device establishes a connection with the second mobile device according to the second connection request and the second mobile device data in the white list.
In practice, the second mobile device may also be a smart phone, a tablet computer, or the like, and the second mobile device may also install an application program (APP) corresponding to the bluetooth device. The second mobile device can communicate and transmit data with the first mobile device in a wireless or wired connection mode.
In step S8, the second mobile device may first transmit the second mobile device data to the first mobile device, so that the first mobile device obtains the second mobile device data. Then, the first mobile device transmits the private key of the Bluetooth device to the second mobile device. In practice, the second mobile device data may be a MAC address of the second mobile device, and the second mobile device data may convert the MAC address into the QR code through an application program (APP). And the first mobile device may scan a QR code generated by the second mobile device through an Application (APP) to obtain second mobile device data of the second mobile device. Similarly, the first mobile device may convert the private key into a QR code through an Application (APP), and the second mobile device scans the QR code generated by the first mobile device to obtain the private key of the wireless bluetooth headset. Besides the first mobile device and the second mobile device can transmit the device data and the private key to each other in the form of the QR code, the first mobile device and the second mobile device can also transmit the device data and the private key in the form of bluetooth, Wi-Fi, Zigbee, Near Field Communication (NFC), or other wireless transmission methods.
After the first mobile device obtains the second mobile device data of the second mobile device, in step S9, the first mobile device writes the second mobile device data into the white list of the bluetooth device. In practice, the first mobile device is bound with the bluetooth device, that is, the white list of the bluetooth device includes the first mobile device data of the first mobile device. At this time, the first mobile device may view and edit the white list of the bluetooth device through an application program (APP). Thus, the first mobile device may write the second mobile device data of the second mobile device into the white list of the bluetooth device.
In this embodiment, the sequence of steps S8 and S9 is not limited to this, and the first mobile device may also obtain the second mobile device data of the second mobile device, and write the second mobile device data into the white list of the bluetooth device, and then the first mobile device transmits the private key of the bluetooth device to the second mobile device.
After the second mobile device obtains the private key of the bluetooth device, in step S10, the second mobile device transmits the second mobile device data and the private key to the bluetooth device as a second connection request to be bound and connected with the bluetooth device. Since the second connection request includes the private key of the bluetooth device and the white list of the bluetooth device includes the second mobile device data, the bluetooth device and the second mobile device establish a connection in step S11. Therefore, the method for binding the Bluetooth device can increase the bound device list through the mobile device bound with the Bluetooth device so as to improve the safety.
Further, the first mobile apparatus may add the mobile apparatus data of the other mobile apparatuses to the white list according to the above steps, so that the other mobile apparatuses can establish a connection with the bluetooth apparatus. In addition, when the first mobile device writes the second mobile device data of the second mobile device into the white list and the second mobile device also establishes a connection with the bluetooth device, the second mobile device may add the mobile device data of the other mobile devices into the white list according to the above steps, so that the other mobile devices can establish a connection with the bluetooth device.
Please refer to fig. 1 and fig. 3. Fig. 3 is a functional block diagram of the system 1 for binding bluetooth devices according to an embodiment of the present invention. The steps of fig. 1 can be achieved by the system 1 of fig. 3 for binding bluetooth devices. In this embodiment, the system 1 for binding bluetooth devices includes a first mobile device 11 and a bluetooth device 12. The first mobile device 11 has first mobile device data and a private key, and is configured to send a first connection request including the first mobile device data and the private key to the bluetooth device 12. The bluetooth device 12 includes a connection module 121, a storage module 122 and a control module 123. The connection module 121 is used for receiving a first connection request sent by the first mobile apparatus 11 and establishing a connection. The memory module 122 contains a white list 1221 and the public key of the bluetooth device 12. The control module 123 is connected to the connection module 121 and the storage module 122. The control module 123 is used for controlling the connection module 121 according to the white list. When the control module 123 determines that the private key in the first connection request received by the connection module 121 matches the public key and the white list 1221 of the storage module 122 contains the first mobile device data, the control module 123 controls the connection module 121 to establish a connection with the first mobile device 11.
In practice, when the first mobile device 11 obtains the private key of the bluetooth device 12 and sends the first connection request to the bluetooth device according to the first mobile device data and the private key, the connection module 121 of the bluetooth device 12 receives the first connection request. At this time, the control module 123 of the bluetooth device 12 first determines whether the private key in the first connection request matches the public key stored in the bluetooth device 12. If the private key and the public key in the first connection request match each other, the control module 123 of the bluetooth device 12 then determines whether the white list 1221 of the storage module 122 contains the first mobile device data. When the white list 1221 of the storage module 122 also includes the first mobile device data of the first mobile device 11, the control module 123 of the bluetooth device 12 controls the connection module 121 to establish a connection with the first mobile device 11. Further, when the private key and the public key in the first connection request match each other and the white list 1221 of the storage module 122 does not contain the first mobile device data of the first mobile device 11, the control module 123 of the bluetooth device 12 further determines whether the storage module 122 is blank. If the white list 1221 of the storage module 122 is blank, the control module 123 of the bluetooth device 12 writes the first mobile device data in the first connection request into the white list 1221 of the storage module 122, and controls the connection module 121 to establish a connection with the first mobile device 11.
Please refer to fig. 2 and fig. 4. Fig. 4 is a functional block diagram of a system 2 for binding bluetooth devices according to an embodiment of the present invention. The steps of fig. 2 can be achieved by the system 1 of fig. 4 for binding bluetooth devices. In this embodiment, the system 2 for binding bluetooth devices includes a first mobile device 21, a second mobile device 22 and a bluetooth device 23. The first mobile device 21 is used to send a private key. The second mobile device 22 has second mobile device data and is coupled to the first mobile device 21. The second mobile device 22 is configured to receive the private key sent by the first mobile device 21, transmit second mobile device data to the first mobile device, and send a second connection request including the second mobile device data and the private key to the bluetooth device 23. The bluetooth device 23 includes a connection module 231, a storage module 232, a white list 2321 stored in the storage module 232, and a control module 233. The connection module 231 is used for connecting with the first mobile device and receiving the second connection request. Please note that the functions of the storage module 232, the white list 2321 and the control module 233 of the bluetooth device 23 are substantially the same as those of the units in the previous embodiment, and are not described herein again. The number of mobile devices is not limited to 2, and the number of mobile devices may be 3 or more.
When the first mobile device 21 has bound the bluetooth device 23, the first mobile device 21 may transmit the private key of the bluetooth device 23 to the second mobile device 22, and the second mobile device 22 may transmit the second mobile device data to the first mobile device 21. Then, the first mobile device 21 can create write data containing the second mobile device data and send the write data to the bluetooth device 23. When the connection module 231 of the bluetooth device 23 receives the written data, the control module 233 writes the second mobile device data in the written data into the white list 2321 of the storage module 232. Since the second connection request includes the private key of the bluetooth device 23 and the white list 2321 of the storage module 232 of the bluetooth device 23 includes the second mobile device data, when the second mobile device 22 sends the second connection request to the bluetooth device 23, the control module 233 of the bluetooth device 23 confirms that the private key in the second connection request matches the public key and the white list 2321 includes the second mobile device data, thereby controlling the connection module 231 to establish a connection with the second mobile device 22.
In summary, in the method for binding a bluetooth device of the present invention, the public and private keys of the bluetooth device and the unique data of the mobile device are used as the basis for determining the connection between the bluetooth device and the mobile device, so that the mobile device is bound to the bluetooth device in a one-to-one manner, thereby improving the security. Furthermore, the method for binding the Bluetooth device prevents other mobile devices from being randomly connected with the Bluetooth device through the authentication mechanism of the public key and the private key of the Bluetooth device, so that the safety is improved. In addition, the method for binding the Bluetooth device only uses the mobile device in the white list to edit the connection list, so as to prevent other mobile devices from being connected with the Bluetooth device, thereby reducing the risk of stealing products and improving the safety. In addition, the method for binding the Bluetooth device increases the bound device list through the mobile device bound with the Bluetooth device, so as to improve the safety.
