The routing device 10 may be a computer system or device that provides data conversion services among multiple networks, such as but not limited to routers, electronic devices that can support hotspots, and the like. Taking the routing device 10 as a router as an example, the router can assign an Internet Protocol (Internet Protocol, IP) address to the electronic device to be connected with the router, and the IP address can be associated with the media access control (Media Access Control, MAC) of the electronic device.

Referring to FIG. 2, FIG. 2 shows a schematic flowchart of a device identification method provided by an embodiment of the present application.

As shown in Figure 2, the device identification method is applied to a routing device, including:

Step 201: Acquire address information of the target electronic device, and determine whether the address information of the target electronic device is random address information.

Specifically, after completing the connection with the target electronic device, the routing device may obtain the MAC address of the target electronic device, and determine whether the MAC address is a generated random address.

Specifically, it is assumed that the routing device is a router, and the target electronic device and the router are wirelessly connected as an example. The user can find and open the wireless local area network in the system settings of the target electronic device to search the surrounding wireless local area network. When the target electronic device searches for the name corresponding to the router in the wireless local area network, it can choose to establish a connection with the router. Possibly, when the target electronic device is connected to the router for the first time, the connection needs to be completed according to the user inputting a password corresponding to the router. Possibly, when the target electronic device is not connected to the router for the first time, the target electronic device can automatically complete the connection with the router when the wireless local area network is opened by the target electronic device. Among them, when the target electronic device is not connected to the router for the first time, if the target electronic device does not choose to record the router password each time it connects with the router, the router password needs to be re-entered when the target electronic device searches for the name corresponding to the router. connect.

Further, after the router completes the connection with the target electronic device, it will obtain the MAC address sent by the target electronic device, and can first determine whether the target electronic device is an electronic device connected for the first time in combination with the stored and assigned address correspondence. Specifically, the router can check whether there is an acquired MAC address of the target electronic device in the relationship between the MAC address of the connected electronic device and the corresponding IP address. If not found, it indicates that the target electronic device is a newly connected electronic device or It is an electronic device whose MAC address is changed. If it is found, it indicates that the target electronic device is a connected electronic device.

When it is determined that the acquired MAC address of the target electronic device does not exist in the relationship between the MAC addresses of the connected electronic devices and their corresponding IP addresses saved by the router, it can be further determined whether the MAC address of the target electronic device is a generated random MAC address address. It should be noted that the random MAC address is automatically generated by the electronic device already connected to the router, that is, after the electronic device establishes a connection with the router with the MAC address, it establishes a connection with the router again with the generated random MAC address.

Step 202: In the case that the address information of the target electronic device is determined to be random address information, obtain auxiliary information of the target electronic device, and match the auxiliary information of the target electronic device with a preset correspondence table.

Specifically, the auxiliary information of the target electronic device is used to characterize the model information of the target electronic device. The model information of the electronic device may be, but not limited to, the brand, model, system version information of the electronic device, and the like.

Specifically, the preset correspondence table includes a plurality of device address information connected to the routing device and auxiliary information corresponding to each device address information. Specifically, the routing device can obtain the MAC address and the corresponding auxiliary information of each new electronic device after the initial connection with each new electronic device is successful, and store them in the preset correspondence table in a corresponding manner. For example, taking the routing device as a router as an example, reference may be made to the schematic diagram of the effect of a preset correspondence table provided by the embodiment of the present application shown in 3. As shown in Figure 3, the preset correspondence table can be viewed by logging in to the client where the router is located, and the preset correspondence table presents auxiliary information of three devices currently connected to the router, their corresponding MAC addresses, and their respective MAC addresses. The address corresponds to the assigned IP address. Among them, the MAC address of the device whose auxiliary information is Ipaid8 is 0C:EE:E6:FE:01:CF, the corresponding IP address assigned by the router is 192.168.3.103; the MAC address of the device whose auxiliary information is Miipcam is C4:6A:B7 :09:59:08, the IP address assigned by the router is 192.168.3.105; the MAC address of the device whose auxiliary information is Huaweix10 is 34:60:B3:10:F6:1E, and the IP address assigned by the router is 192.168.3.106 . In the preset correspondence table, the corresponding connection valid time is also displayed for each device. For example, the valid time of the device whose auxiliary information is Ipaid8 is 00:38:48, and the valid time of the device whose auxiliary information is Miipcam is 01: At 48:07, the effective time of the device whose auxiliary information is Huaweix10 is 01:40:26.

Specifically, after determining that the MAC address of the target electronic device belongs to a random MAC address, the routing device can obtain auxiliary information of the target electronic device through data information sent or received by the target electronic device, and save the obtained auxiliary information with the routing device. The auxiliary information in the preset correspondence table is matched.

Step 203: In the case where the matching degree of the auxiliary information corresponding to the auxiliary information of the target electronic device and any one of the device address information connected to the routing device in the preset correspondence table is greater than or equal to the preset matching degree, the matching degree of the target electronic device is The address information is added to the preset correspondence table.

Specifically, the routing device can match the auxiliary information of the target electronic device with any auxiliary information in the preset correspondence table, and when the matching degree is greater than or equal to the preset matching degree, it can be determined that the target electronic device is connected to the routing device and add the MAC address of the target electronic device to the MAC address corresponding to the auxiliary information of the target electronic device in the preset correspondence table.

It should be noted that the preset matching degree mentioned above can be set by default by the routing device, for example, the preset matching degree can be set to 100% by default, and the preset matching degree in this embodiment is not limited to 100%.

In this embodiment of the present application, after obtaining the address information of the target electronic device, it is possible to determine whether it is random address information, and if it is determined to be a random address, the auxiliary information of the target electronic device is obtained and the preset correspondence table matches. If the matching degree of the auxiliary information is greater than or equal to the preset matching degree, the obtained address information will be added to the preset correspondence table, which can ensure that the routing device can still be accurately and quickly identified after the target electronic device is replaced with random address information, and correspondingly execute the corresponding The functions of application identification and device identification, etc., can improve the security of electronic devices and ensure the normal user experience.

As an embodiment of the present application, reference may be made to a schematic flowchart of another device identification method shown in FIG. 4 .

As shown in Figure 4, the device identification method is applied to a routing device, including:

Step 401: Determine whether a preset character string exists in the address information of the target electronic device.

Step 402 , in the case that a preset character string is detected in the address information of the target electronic device, determine that the address information of the target electronic device is random address information.

Specifically, in order to better distinguish whether the acquired target electronic device is an electronic device connected to the routing device, it can be determined whether the MAC address is a random MAC address according to the character string corresponding to the MAC address of the target electronic device. Specifically, taking the routing device as a router as an example, the router can determine whether the character string at the preset position is a preset character string according to the character string corresponding to the MAC address of the target electronic device, and if the character string at the preset position is detected is a preset character string, the MAC address of the target electronic device is taken as a random MAC address.

Exemplarily, the MAC address of the target electronic device is 36:43:6E:6A:9A:09 (the MAC address is represented as 12 hexadecimal numbers), and the preset string in the router is that the second digit of the MAC address is 2 or 6 or A or E, that is, when the router detects that the second character string is any one of 2 or 6 or A or E in the obtained MAC address of the target electronic device, it can determine that the MAC address of the target electronic device is random. MAC address.

Step 403: Acquire auxiliary information of the target electronic device, and match the auxiliary information of the target electronic device with a preset correspondence table.

Specifically, step 403 is the same as step 202, and details are not repeated here.

Step 404: In the case that the matching degree of the auxiliary information of the target electronic device and the auxiliary information corresponding to any one of the device address information connected to the routing device in the preset correspondence table is greater than or equal to the preset matching degree, the matching degree of the target electronic device is The address information is added to the preset correspondence table.

Specifically, step 404 is the same as step 203, and details are not repeated here.

Step 405: Obtain auxiliary information of the target electronic device when it is detected that there is no preset character string in the address information of the target electronic device.

Step 406: Add the address information of the target electronic device and the auxiliary information of the target electronic device to the preset correspondence table.

Specifically, when the routing device detects that the character string corresponding to the MAC address of the target electronic device does not have a preset character string, it can take the target electronic device as the electronic device to be connected for the first time, and further obtain auxiliary information of the target electronic device It is added to the preset correspondence table together with the MAC address, so that when the electronic device generates a random MAC address and connects with the routing device, it can be quickly identified by the routing device.

As another embodiment of the present application, after obtaining the auxiliary information of the target electronic device, and before matching the auxiliary information of the target electronic device with the preset correspondence table, the method further includes:

Match the auxiliary information of the target electronic device with the preset first database, and determine the category information of the target electronic device; the preset first database includes a plurality of different device model information and category information corresponding to each device model information. ;

Match the auxiliary information of the target electronic device with the preset correspondence table, including:

When it is determined that the category information of the target electronic device is an intelligent electronic device, the auxiliary information of the target electronic device is matched with a preset correspondence table.

Specifically, after it is determined that the MAC address of the target electronic device belongs to a random MAC address, there may be some MAC addresses of non-smart electronic devices in the random MAC address, and the MAC addresses of the non-smart electronic devices conform to the MAC addresses determined as random MAC addresses. Conditions, for example, a preset character string exists in the character string corresponding to the MAC address of the non-intelligent electronic device. Understandably, non-intelligent electronic devices cannot generate random MAC addresses. In order to more accurately distinguish between intelligent electronic devices that can generate random MAC addresses and non-intelligent electronic devices whose MAC addresses are judged to be random MAC addresses, routing devices can be After obtaining the auxiliary information of the target electronic device, the auxiliary information of the target electronic device is matched with the preset first database to determine the category of the target electronic device, and in the case of determining that the target electronic device is a smart device according to the category of the target electronic device The auxiliary information of the target electronic device is matched with a preset correspondence table.

Specifically, taking the routing device as a router as an example, reference may be made to the schematic diagram of the effect of a preset first database provided by an embodiment of the present application shown in FIG. 5 .

It is an intelligent electronic device. Wherein, when the router obtains the auxiliary information of the target electronic device as Ipaid8, it can match with the preset first database to obtain the device type as tablet, and determine that the target electronic device is an intelligent electronic device; when the router obtains the auxiliary information of the target electronic device When the information is Miipcam, it can be matched with the preset first database to obtain the device type as a camera, and determine that the target electronic device is not an intelligent electronic device; when the router obtains the auxiliary information of the target electronic device as Huaweix10, it can be matched with the preset device. The first database performs matching to obtain a device type as a mobile phone, and determines that the target electronic device is an intelligent electronic device.
