Detailed Description
With the development of the intelligent control technology, the application of the internet of things device 100 is more and more extensive. Bluetooth is a short-distance wireless communication protocol standard and is widely applied to various terminal devices and Internet of things devices. During Bluetooth connection, identity identification can be carried out through the Bluetooth MAC address, namely, after the Bluetooth connection is completed, the Bluetooth connection parties can identify the identities of the Bluetooth MAC address parties and identify the identities of the Bluetooth MAC address parties.
The Bluetooth-based identity recognition can be used for improving user experience in certain scenes, for example, a Bluetooth sound box or vehicle-mounted entertainment equipment provides preference settings such as different songs for different users through different connected mobile phone Bluetooth, and an intelligent air conditioner provides personalized functions such as temperature, humidity and pendulum wind for different users through different connected mobile phone Bluetooth. However, in this way, there is a risk that the MAC address is stolen, that is, an illegal device may control the internet of things device by modifying its MAC address, which may cause a security risk of the internet of things device.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a schematic block diagram of a structure of an internet of things device 100 according to an embodiment of the present disclosure, where the internet of things device 100 includes a bluetooth connection device 110, a memory 120 and a processor 130, and the memory 120 and the processor 130 are electrically connected to each other directly or indirectly for implementing data interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The bluetooth connection device 110 includes at least one software function module which can be stored in the memory 120 in the form of software or Firmware (Firmware) or solidified in an Operating System (OS) of the internet of things device 100. The processor 130 is used for executing executable modules stored in the memory 120, such as software functional modules and computer programs included in the bluetooth connection apparatus 110.
Referring to fig. 2, the internet of things device 100 may be communicatively connected to the server 200 through the network 300, and the server 200 may also be communicatively connected to a plurality of terminal devices 400 (terminal devices 400-terminal devices 400) through the network 300, respectively.
Referring to fig. 3, fig. 3 is a schematic flow chart of the bluetooth connection method provided in this embodiment, and the bluetooth connection method includes steps S110 to S150.
Step S110, a pre-stored authorization information table is obtained, where the authorization information table includes an identity of an authorized device and verification information of the authorized device.
Step S120, determining a target device, where the target device is a device in an environment where the internet of things device 100 is located, and the identity of the target device is the same as the identity of the authorized device in the authorization information table.
Step S130, acquiring the verification information of the target device.
Step S140, determining, from the authorization information table, verification information corresponding to the target device according to the identity of the target device.
And step S150, performing connection authority verification according to the verification information of the target device and the verification information corresponding to the target device.
And step S160, if the connection authority is successfully verified, establishing Bluetooth connection with the target equipment.
In this embodiment, the connection authority of the target device is determined through the pre-stored authorization information table, so that the bluetooth connection is established between the target device and the target device when the connection authority of the target device is successfully verified, thereby preventing an illegal device having the same MAC address as an authorized device from controlling the internet of things device 100, reducing the risk of the internet of things device 100 being illegally controlled, and improving the security of the internet of things device 100.
In one embodiment, the authorization information table may be set directly by the user according to the other terminal device 400 that may control the internet of things device 100, and then stored in the internet of things device 100.
Referring to fig. 2, in another embodiment, the authorization information table may be synchronized by the master authorization device to the internet of things device 100. The main authorization device is a device that is successfully paired with the internet of things device 100, and after the internet of things device 100 is successfully paired with the main authorization device, the main authorization device is not directly paired with the other terminal devices 400. After the master authorization device is successfully paired with the internet of things device 100, the master authorization device generates its own verification information, identity identifier and device type identifier, and synchronizes the verification information, identity identifier and device type identifier to the internet of things device 100, where the synchronization process may be: the master authorization device sends the verification information, the identity identifier and the device type identifier to the server 200. The server 200 may store the verification information, the identity identifier, and the device type identifier in an authorization information table configured thereon, or may send the verification information, the identity identifier, and the device type identifier to the internet of things device 100, and the internet of things device 100 stores these pieces of information in a storage information table configured on the internet of things device 100.
After the main authorization device is successfully paired with the internet of things device 100, the main authorization device may also interact with other terminal devices 400, generate verification information, an identity identifier, and a device type identifier of the other terminal devices 400, and send the verification information, the identity identifier, and the device type identifier to the server 200. The server 200 may store the verification information, the identity identifier, and the device type identifier in an authorization information table configured thereon, or may send the verification information, the identity identifier, and the device type identifier to the internet of things device 100. The internet of things device 100 stores this information in a storage information table configured on the internet of things device 100. In short, the authorized devices include the master authorization device and the other terminal devices 400 authorized by the master authorization device. The master authorization device also sends the verification information, the identity identifier and the device type identifier corresponding to each terminal device 400 to the corresponding terminal device 400.
In this embodiment, the verification information is data used for verifying whether the terminal device 400 can be connected to the internet of things device 100, and the verification information may include authorization data representing whether the terminal device 400 has been subjected to connection authorization and validity data representing whether the authorization of the terminal device 400 is valid; the identification is data for identifying each terminal device 400, and the device type identification is data for characterizing whether the terminal device 400 is a master authorization device or an authorized device. When the device connected to the internet of things needs to be authorized by the master authorization device, the authorization data may be generated by the master authorization device and then shared with the corresponding other terminal devices, where the authorization data may be a digital code or a character code randomly generated by the master authorization device, or the authorization data may also be a digital code or a character code input by a user, and the authorization data may be multiple bits, for example, 6 bits. The validity data may be generated by the master authorization device and then shared with the corresponding other terminal devices.
Of course, in this embodiment, the terminal device 400 successfully paired with the internet of things for the first time refers to the terminal device 400 successfully paired with the internet of things device 100 for the first time when the internet of things device 100 is put into use, or the terminal device 400 successfully paired with the internet of things device 100 for the first time after the internet of things device 100 is reset.
To aid understanding, the authorized device, the master authorization device, is described below in connection with an actual scenario.
For example, in the communication system, the internet of things device 100, the server 200, the terminal device a, the terminal device B, the terminal device C, the terminal device D, the terminal device E, and the terminal device F are included. Initially, each terminal device 400 is connected and paired with the internet of things device 100, but if the terminal device a is successfully paired first, the terminal device a is the master authorization device, and the terminal device B, the terminal device C, the terminal device D, the terminal device E, and the terminal device F are no longer paired with the internet of things device 100. At this time, the terminal device a synchronizes the verification information, the identity identifier, and the device type identifier of itself to the internet of things device 100. The terminal device a interacts with the terminal device B, the terminal device C and the terminal device D, and sends the generated verification information, the generated identity and the generated device type identifier to the corresponding terminal device B, the corresponding terminal device C and the corresponding terminal device D to complete authorization, that is, the authorized devices include the terminal device a, the terminal device B, the terminal device C and the corresponding terminal device D.
In this embodiment, the other terminal devices 400 are authorized by the master authorization device, so that the terminal devices 400 connectable to the internet of things device 100 can be determined by the user as needed, and then the corresponding terminal devices 400 are authorized, thereby improving the user experience.
Optionally, in this embodiment, step S120 includes determining a target device from devices to be connected, where the devices to be connected are terminal devices 400 in an environment where the internet of things device 100 is located, and the bluetooth is already turned on and the identity identifier is the same as the identity identifier in the authorization information table.
In this embodiment, for specifically determining the target device, the internet of things device 100 may operate in a master mode or a slave mode. Still taking the communication system including the internet of things device 100, the server 200, the terminal device a, the terminal device B, the terminal device C, the terminal device D, the terminal device E, and the terminal device F as an example, if the internet of things device 100 includes the terminal device a, the terminal device B, the terminal device C, the terminal device E, and the terminal device F within the bluetooth communication range, then the terminal device a, the terminal device B, and the terminal device C are connectable devices. The target device is then one of terminal device a, terminal device B, and terminal device C.
Optionally, in this embodiment, determining the target device from the devices to be connected includes determining whether a master authorization device exists in the devices to be connected; and if the main authorization device exists in the devices to be connected, taking the main authorization device as the target device.
In this embodiment, the main authorization device is used as the terminal device preferentially connected, so that the user experience can be improved, and the control authority of the owner of the internet of things device on the internet of things device is ensured.
Optionally, in this embodiment, the determining the target device from the devices to be connected further includes, if the master authorized device does not exist in the devices to be connected, using the device to be connected with the highest priority as the target device.
In this embodiment, when the master authorization device does not exist in the devices to be connected, the connection order is determined according to the priority, so that the user experience can be improved.
Referring to fig. 4, optionally, in this embodiment, the bluetooth connection method further includes, if the connection authority check fails, executing step S170-step S180.
Step S170, determining whether all the devices to be connected have been targeted devices.
Step S180, if the device to be connected which is not taken as the target device exists, determining a new target device from the device to be connected which is not taken as the target device, and re-executing the step of obtaining the verification information of the target device according to the new target device.
In this embodiment, under the condition that the target device cannot pass the connection verification, the new terminal device 400 is replaced as the target device, and it is ensured that the authorized terminal device 400 is connected to the internet of things device 100 as much as possible, so that the user experience is improved.
Of course, in this embodiment, under the condition that the connection permission of the target device fails to be checked, the internet of things device may send information that the connection permission check fails to the master authorization device, and after receiving the information that the connection permission check fails, the master authorization device may regenerate the authorization data corresponding to the terminal device and share the authorization data with the internet of things device and the corresponding terminal device.
Optionally, in this embodiment, determining a new target device from the devices to be connected that have never been target devices includes acquiring, from the devices to be connected that have never been target devices, a device to be connected with the highest priority as the new target device.
In the embodiment, when a new target device is selected, the target device is selected according to the priority sequence, so that the selected result can be ensured to better meet the user requirement, and the user experience is improved.
Optionally, in this embodiment, the bluetooth connection method further includes acquiring a number of times of connection for establishing bluetooth connection between a pre-stored authorized device and the internet of things device 100; and determining the priority of each device to be connected according to the connection times of the authorized devices corresponding to the devices to be connected, wherein the higher the connection times is, the higher the priority is.
In this embodiment, the connection times of establishing the bluetooth connection between the authorized device and the internet of things device 100 are prestored, and the connection permission is determined according to the connection times, so that the user experience can be further improved.
Optionally, in this embodiment, when the verification information includes the authorization data and the validity data, performing connection permission verification according to the verification information of the target device and the verification information corresponding to the target device, including performing authorization verification and validity verification on the target device according to the verification information of the target device, the authorization data corresponding to the target device, and the validity data corresponding to the target device; if the authorization verification is successful and the validity verification is successful, judging that the connection authority verification of the target equipment is successful; and if the authorization verification fails or the validity verification fails, judging that the connection authority verification fails.
In this embodiment, the target data is checked through the authorization data and the validity data, so that the connection state between the terminal device 400 and the internet of things device 100 can be controlled under different connection conditions, and the user experience is improved.
Optionally, in this embodiment, authorization verification and validity verification are performed on the target device according to the verification information of the target device, the authorization data corresponding to the target device, and the validity data corresponding to the target device, including determining whether the verification information of the target device is consistent with the authorization data corresponding to the target device; if the verification information of the target equipment is consistent with the authorization data corresponding to the target equipment, judging that the authorization verification is successful; if the verification information of the target equipment is inconsistent with the authorization data corresponding to the target equipment, judging that the authorization verification fails; if the validity data corresponding to the target equipment is in a valid state, the validity verification is successful; and if the validity data corresponding to the target equipment is in an invalid state, the validity check fails.
The embodiment is used for specifically performing authorization verification and validity verification.
In this embodiment, after it is determined that the authorization check of the target device fails, the internet of things device may update the validity data of the target device, and update the validity data to an invalid state. The internet of things equipment can also inform the master authorization equipment of the information that the authorization and the verification of the target equipment are not passed, and the master authorization equipment can authorize the target equipment again after receiving the information that the authorization and the verification of the target equipment are not passed, that is, the authorization check code of the target equipment is regenerated, and the authorization check code is synchronized to the internet of things equipment and is shared to the target equipment.
Optionally, in this embodiment, determining whether the verification information of the target device is consistent with authorization data corresponding to the target device includes determining whether the target device is a master authorization device, where the master authorization device is a first device that is successfully paired with the internet of things device 100; if the target equipment is the main authorization equipment, judging whether the verification information of the target equipment conforms to the authorization data corresponding to the target equipment or not; if the verification information of the target equipment is consistent with the authorization data corresponding to the target equipment, judging that the verification information of the target equipment is consistent with the authorization data corresponding to the target equipment; if the verification information of the target equipment does not accord with the authorization data corresponding to the target equipment, new authorization data is obtained; and if the new authorization data is inconsistent with the old authorization data, judging that the verification information of the target device is consistent with the authorization data corresponding to the target device.
In this embodiment, when the authorization data of the master authorization device is verified, if the authorization verification of the master authorization device is unsuccessful, the master authorization device is notified to update the authorization data, and when the master authorization data is successfully updated, it is determined that the target device authentication information is consistent with the authorization data corresponding to the target device, so that the master authorization device can preferentially ensure control over the internet-of-things device 100.
Of course, in this embodiment, when the verification information of the target device does not match the authorization data corresponding to the target device, after acquiring new authorization data, the step of determining whether the verification information of the target device matches the authorization data corresponding to the target device may be executed again until the preset number of cycles is met.
In this embodiment, the valid state of the validity data of the master authorization device may be always valid, that is, as long as the target device is the master authorization device, it may be considered that the validity check of the master authorization device is successful.
In one possible embodiment, the identity comprises a MAC address of the device. In another possible embodiment, the identity is obtained from a hash function value of a character formed by the bluetooth MAC address of the terminal device 400 and the IMEI of the terminal device 400, and the identity may be a character at some specific position in the whole hash function value that is intercepted, for example, a specific 12-bit or 16-bit may be intercepted, and so on. The hash function value can be calculated by a hash function, MD5, SHA1, SHA256, and other algorithms. When there are two or more IMEI numbers in the IMEI of the terminal device 400, the first IMEI number can be selected for calculation.
The hash function value of the character formed by the MAC address of the terminal device 400 and the IMEI of the terminal device 400 is used as the identity of the terminal device 400, so that a third party can be prevented from obtaining the MAC data of the bluetooth of the terminal device 400, and the security of the internet of things device 100 can be further improved.
Optionally, in this embodiment, the bluetooth connection method further includes, after the bluetooth connection is established with the target device, acquiring preference information of the target device for the internet of things device 100; operating according to the preference information.
When the terminal equipment operates the Internet of things equipment, the Internet of things equipment records operation content and can synchronize the content to the server. The server can calculate personal preference through a preference algorithm according to the historical operation information, establish a personal database and update and perfect the database according to the operation of the corresponding user.
