Description

Technical Field

[0002] Nowadays, mobile phones have increasingly diverse functions. For example, many mobile phone manufacturers provide mobile phones with random local area network (Media Access Control Address, MAC) addresses so that the mobile phone's MAC address changes randomly every time it connects to WIFI, which can avoid the risk of personal privacy being leaked due to the collection of MAC addresses.

[0003] However, functions such as application identification and device identification on a router rely on accurate device identification. When a device connects to the router using a generated random MAC address, the router cannot accurately and quickly identify the device. This not only affects the router's application identification and device identification functions, but also the user's experience when connecting to the router. Summary of the Invention

[0062] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0063] The terms "first," "second," "third," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0064] Please see Figure 1 , Figure 1 A schematic diagram of the architecture of a device identification system provided in an embodiment of this application is shown.

[0065] like Figure 1 As shown, the device identification system includes routing device 10 and electronic devices, wherein:

[0066] Routing device 10 can be a computer system or device that provides data conversion services between multiple networks, such as, but not limited to, routers and electronic devices that support hotspots. Taking router 10 as an example, the router can assign Internet Protocol (IP) addresses to electronic devices that want to connect to the router. These IP addresses can correspond to the Media Access Control (MAC) addresses of the electronic devices, and data can be sent or received to their respective corresponding electronic devices through different IP addresses. When an electronic device that has already connected to the router reconnects to the router, the router can accurately identify the electronic device through the MAC address it sends and execute corresponding application functions based on the data transmitted by the electronic device. The connection between the router and the electronic device can be wireless or wired.

[0067] The electronic device can be one or more electronic devices, and multiple electronic devices may include electronic device 20a, electronic device 20b, electronic device 20c, etc. The electronic device can connect to the routing device 10 to achieve data transmission between different electronic devices. Taking the routing device 10 as a router as an example, the electronic device can establish a connection with the router via wireless or wired connection. Possibly, when the electronic device is wirelessly connected to the router, the electronic device can open the wireless LAN settings, search for the router name to connect to wirelessly, and enter the corresponding router password to establish a connection. Possibly, when the electronic device is wiredly connected to the router, the electronic device can find the network corresponding to the router name in the network and Internet settings and enter the password to establish a connection.

[0068] The electronic devices involved in the embodiments of this application may be mobile phones, tablets, desktops, laptops, notebook computers, ultra-mobile personal computers (UMPCs), handheld computers, netbooks, personal digital assistants (PDAs), routing devices, virtual reality devices, etc.

[0069] Please see Figure 2 , Figure 2 A flowchart illustrating a device identification method provided in an embodiment of this application is shown.

[0070] like Figure 2 As shown, this device identification method is applied to routing devices and includes:

[0071] Step 201: Obtain the address information of the target electronic device and determine whether the address information of the target electronic device is random address information.

[0072] Specifically, after establishing a connection with the target electronic device, the routing device can obtain the MAC address of the target electronic device and determine whether the MAC address is a generated random address.

[0073] Specifically, taking a router as the routing device and a wireless connection between the target electronic device and the router as an example, the user can find and enable Wi-Fi in the target electronic device's system settings to search for nearby Wi-Fi networks. When the target electronic device finds the name corresponding to the router in the Wi-Fi network, it can choose to establish a connection with that router. It's possible that when the target electronic device is connecting to the router for the first time, the user will need to enter the password corresponding to the router to complete the connection. It's also possible that when the target electronic device is not connecting to the router for the first time, it will automatically connect to the router when it enables Wi-Fi. However, if the target electronic device does not save the router password each time it connects to the router, it will still need to re-enter the router password to complete the connection when it finds the router's name.

[0074] Furthermore, after the router establishes a connection with the target electronic device, it obtains the MAC address sent by the target electronic device. It can then use this information, along with the saved address mappings, to determine if the target electronic device is a newly connected device. Specifically, the router can search the mappings of the MAC addresses of already connected electronic devices against their corresponding IP addresses to see if the obtained MAC address of the target electronic device exists. If not found, it indicates that the target electronic device is either a newly connected device or an device that has changed its MAC address; if found, it indicates that the target electronic device is an already connected device.

[0075] If it is determined that the MAC address of the target electronic device does not exist in the router's saved list of MAC addresses and corresponding IP addresses of connected electronic devices, it can be further determined whether the MAC address of the target electronic device is a generated random MAC 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 using its MAC address, it then re-establishes a connection with the router using the generated random MAC address.

[0076] Step 202: If the address information of the target electronic device is determined to be random address information, obtain the auxiliary information of the target electronic device and match the auxiliary information of the target electronic device with a preset correspondence table.

[0077] Specifically, the auxiliary information of the target electronic device is used to characterize the model information of the target electronic device. This model information may include, but is not limited to, the brand, model number, system version, etc.

[0078] Specifically, the preset mapping table includes multiple device address information connected to the routing device and corresponding auxiliary information for each device address. Specifically, after successfully connecting to each new electronic device for the first time, the routing device can obtain the MAC address of each new electronic device and its corresponding auxiliary information, and store them in the preset mapping table accordingly. For example, taking a router as an example, see the schematic diagram of the effect of a preset mapping table provided in this embodiment of the application shown in Figure 3. Figure 3 As shown, the preset mapping table can be viewed by logging into the client where the router is located. This table displays auxiliary information for the three devices currently connected to the router, their respective MAC addresses, and the IP addresses assigned to those MAC addresses. Specifically, the MAC address of the device with auxiliary information "Ipaid8" is 0C:EE:E6:FE:01:CF, and its assigned IP address is 192.168.3.103; the MAC address of the device with auxiliary information "Miipcam" is C4:6A:B7:09:59:08, and its assigned IP address is 192.168.3.105; and the MAC address of the device with auxiliary information "Huaweix10" is 34:60:B3:10:F6:1E, and its assigned IP address is 192.168.3.106. The preset correspondence table also displays the corresponding connection validity time for each device. For example, the validity time for the device with auxiliary information Ipaid8 is 00:38:48, the validity time for the device with auxiliary information Miipcam is 01:48:07, and the validity time for the device with auxiliary information Huaweix10 is 01:40:26.

[0079] Specifically, after determining that the MAC address of the target electronic device is a random MAC address, the routing device can obtain the auxiliary information of the target electronic device through the data information sent or received by the target electronic device, and match the obtained auxiliary information with the auxiliary information stored in the preset correspondence table of the routing device.

[0080] Step 203: If the matching degree between the auxiliary information of the target electronic device and the auxiliary information corresponding to any device address information connected to the routing device in the preset correspondence table is greater than or equal to the preset matching degree, add the address information of the target electronic device to the preset correspondence table.

[0081] Specifically, the routing device can match the auxiliary information of the target electronic device with any one of the auxiliary information in the preset correspondence table. When the matching degree is greater than or equal to the preset matching degree, it can determine that the target electronic device is an electronic device that has been 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.

[0082] It should be noted that the preset matching degree mentioned above can be set by the routing device by default. 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%.

[0083] In this embodiment, after obtaining the address information of the target electronic device, it can be determined whether it is random address information. If it is determined to be random address information, the auxiliary information of the target electronic device can be obtained and matched with a preset correspondence table. If the matching degree of the auxiliary information is greater than or equal to the preset matching degree, the obtained address information can be added to the preset correspondence table. This can ensure that the routing device can still accurately and quickly identify the target electronic device after it is changed to random address information, and perform corresponding application identification and device identification functions. This can improve the security of electronic devices and ensure the normal user experience.

[0084] As one embodiment of this application, see [reference needed]. Figure 4 A flowchart illustrating another device identification method is shown.

[0085] like Figure 4 As shown, this device identification method is applied to routing devices and includes:

[0086] Step 401: Determine whether a preset string exists in the address information of the target electronic device.

[0087] Step 402: If a preset 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.

[0088] Specifically, to better distinguish whether the target electronic device is already connected to the routing device, the string corresponding to the target electronic device's MAC address can be used to determine whether the MAC address is a random MAC address. Specifically, taking a router as an example, the router can determine whether the string at a preset location is a preset string based on the string corresponding to the target electronic device's MAC address. If the string at the preset location is detected as a preset string, the target electronic device's MAC address is then used as a random MAC address.

[0089] For example, the target electronic device's MAC address is 36:43:6E:6A:9A:09 (the MAC address is represented by 12 hexadecimal numbers). The router has a preset string where the second digit of the MAC address is 2, 6, A, or E. That is, when the router detects that the second digit of the target electronic device's MAC address is any one of 2, 6, A, or E, it can determine that the target electronic device's MAC address is a random MAC address.

[0090] Step 403: Obtain the auxiliary information of the target electronic device and match the auxiliary information of the target electronic device with a preset correspondence table.

[0091] Specifically, step 403 is the same as step 202, and will not be repeated here.

[0092] Step 404: If the matching degree between the auxiliary information of the target electronic device and the auxiliary information corresponding to any device address information connected to the routing device in the preset correspondence table is greater than or equal to the preset matching degree, add the address information of the target electronic device to the preset correspondence table.

[0093] Specifically, step 404 is the same as step 203, and will not be repeated here.

[0094] Step 405: If the preset string is not found in the address information of the target electronic device, obtain the auxiliary information of the target electronic device.

[0095] Step 406: Add the address information and auxiliary information of the target electronic device to the preset corresponding table.

[0096] Specifically, when the routing device detects that the string corresponding to the MAC address of the target electronic device does not exist in the preset string, it can treat the target electronic device as the electronic device that is being connected for the first time. Then, it can further obtain the auxiliary information of the target electronic device and add it to the preset correspondence table along with the MAC address, so that the routing device can quickly identify it when the electronic device generates a random MAC address and connects to the routing device.

[0097] As another embodiment of this application, after obtaining the auxiliary information of the target electronic device and before matching the auxiliary information of the target electronic device with a preset correspondence table, the method further includes:

[0098] The auxiliary information of the target electronic device is matched with a preset first database to determine the category information of the target electronic device; the preset first database includes multiple different device model information and the category information corresponding to each device model information.

[0099] Matching the auxiliary information of the target electronic device with a preset mapping table, including:

[0100] If the target electronic device is determined to be a smart electronic device, the auxiliary information of the target electronic device is matched with a preset correspondence table.

[0101] Specifically, after determining that the MAC address of the target electronic device is a random MAC address, there may also be some MAC addresses of non-smart electronic devices among these random MAC addresses. These non-smart electronic devices' MAC addresses meet the conditions for being judged as random MAC addresses, for example, the string corresponding to their MAC addresses exists in a preset string. Understandably, non-smart electronic devices cannot generate random MAC addresses. To more accurately distinguish between smart electronic devices that can generate random MAC addresses and non-smart electronic devices whose MAC addresses meet the criteria for being judged as random MAC addresses, the routing device can, after obtaining the auxiliary information of the target electronic device, match the auxiliary information of the target electronic device with a preset first database to determine the category of the target electronic device. If the target electronic device is determined to be a smart device based on its category, the auxiliary information of the target electronic device is then matched with a preset correspondence table.

[0102] Specifically, taking a router as an example, please refer to... Figure 5 The illustration shows the effect of a preset first database provided by an embodiment of this application. Figure 5 As shown, the preset first database can be viewed by logging into the client where the router is located. This preset first database includes auxiliary information for the three devices currently connected to the router, their respective device categories, and whether each belongs to a smart electronic device. Specifically, when the router obtains the auxiliary information of the target electronic device as "Ipaid8", it can match it with the preset first database to determine the device category as "tablet", thus identifying the target electronic device as a smart electronic device. When the router obtains the auxiliary information of the target electronic device as "Miipcam", it can match it with the preset first database to determine the device category as "camera", thus identifying the target electronic device as not a smart electronic device. When the router obtains the auxiliary information of the target electronic device as "Huaweix10", it can match it with the preset first database to determine the device category as "mobile phone", thus identifying the target electronic device as a smart electronic device. It is understood that the embodiments of this application are not limited to the auxiliary information of the electronic devices mentioned above.

[0103] As another embodiment of this application, obtaining auxiliary information of the target electronic device includes:

[0104] Determine the data information of the target electronic device from the Hypertext Transfer Protocol information sent by the target electronic device;

[0105] The data information of the target electronic device is matched with a preset second database; wherein, the preset second database may include multiple different device data information connected to the routing device and the model information corresponding to each device data information;

[0106] If the data information of the target electronic device is successfully matched with the preset second database, the model information corresponding to the device data information connected to the routing device in the preset second database is used as auxiliary information of the target electronic device.

[0107] Specifically, after establishing a connection with the target electronic device, the routing device can forward the data sent by the target electronic device to other devices. When the data sent by the target electronic device is in the form of Hypertext Transfer Protocol (HTTP), the routing device can obtain data information from the user-agent information of the HTTP protocol according to the configuration file preset in the data transmission channel, and match the data information with a preset second database. If the match is successful, the model information corresponding to the data information in the preset second database is used as auxiliary information of the target electronic device.

[0108] As another embodiment of this application, obtaining auxiliary information of the target electronic device may further include:

[0109] Obtain the hostname information of the target electronic device from the Dynamic Host Configuration Protocol (DHCP) information sent by the target electronic device;

[0110] The model information of the target electronic device is determined based on its hostname information, and this model information is used as auxiliary information for the target electronic device.

[0111] Specifically, after the routing device establishes a connection with the target electronic device, the target electronic device can request an IP address from the routing device via Dynamic Host Configuration Protocol (DCHP). The routing device can then obtain the hostname information from the DCHP header sent by the target electronic device. The hostname information obtained by the routing device varies depending on the brand of the electronic device. For example, taking a router as an example, if the electronic device wirelessly connected to the router is a Huawei device, the hostname information obtained by the router might be the device's specific model number plus a string. If the electronic device wirelessly connected to the router is an Apple device, the hostname information obtained by the router might be the device's specific model number. If the electronic device wirelessly connected to the router is a Xiaomi device, the hostname information obtained by the router might be the device's specific model number plus a username.

[0112] As another embodiment of this application for obtaining auxiliary information about the target electronic device, when the target electronic device supports the Multicast Domain Name System (MDNS) protocol, it can also send MDNS data packets to the routing device. The routing device can obtain the device model of the target electronic device based on the domain name information in the MDNS data packet. The MDNS data packet is not limited to including the domain name, multicast address, device model, IP address, etc. of the target electronic device.

[0113] As another embodiment of obtaining auxiliary information of the target electronic device in this application, the routing device can also obtain the device identifier of the target electronic device based on the broadcast sent by the connected target electronic device. For example, taking the routing device as a router, when the target electronic device is a Huawei series device, after the target electronic device connects to the router, it will send a User Datagram Protocol (UDP) broadcast to any device connected to the router. After receiving the UDP broadcast sent by the target electronic device, the router can extract the device UUID information from the UDP broadcast and use the device UUID information as the device identifier of the Huawei series electronic device. That is, when the router extracts the device UUID information from the broadcast sent by the target electronic device, it can determine that the target electronic device is a Huawei series electronic device.

[0114] As another embodiment of this application for obtaining auxiliary information of the target electronic device, the routing device can also obtain the device model of the target device from a request issued by an application running on the target electronic device. For example, when the target electronic device uses an application, the application issues an acquisition request, and the routing device can extract the device model from the acquisition request received by the application. If the routing device extracts uid information or m2 information from the acquisition request, it can use the device model information contained in the uid information or m2 information as the device model of the target electronic device.

[0115] In conjunction with the above embodiments for obtaining auxiliary information of the target electronic device, please refer to... Figure 6 , Figure 6 This illustration shows the effect of another preset correspondence table provided in an embodiment of this application. For example... Figure 6As shown, the preset mapping table can be viewed by logging into the client where the router is located. The preset mapping table displays the MAC addresses of the three devices currently connected to the router, their respective hostnames, domain names, and device types. The hostname, domain name, and device type information can be used to characterize the electronic devices.
