Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification.
The networking system can comprise a cloud platform and a local area network communicated with the cloud platform. In the local area network, a switch, a router and an identification device are provided, and a plurality of terminals, which can be cameras, PCs, handheld terminals, printers and the like, are hung under the switch. The cloud platform can be composed of a plurality of servers, and the identification device can also be one server. Of course, the specific architecture of the cloud platform and the recognition device may be implemented in other forms, which is not limited to this.
In the networking shown in fig. 1, aggregation switches 20 and 21 hung on a local area network are arranged beside identification devices 10 and 11, and access switches 30 to 35 are arranged below the aggregation switches 20 and 21. The access switches 30, 32, 33 and 35 are connected to the terminals 40 to 43, the access switches 31 and 34 are respectively connected to the aggregation switches 20 and 21 and the access switches 30, 32, 33 and 35, and the aggregation switches 20 and 21 are respectively connected with the cloud platform through the routers 50 and 51. For other application scenarios, for example, the identification device may also be disposed in the routers 50 and 51, and it is only necessary that the network device in the local area network can be connected to the identification device and forward or mirror the packet sent by the terminal to the identification device. Further, the terminal identification function of the identification device may be integrated into a certain network device.
The application provides a terminal identification method, as shown in fig. 2, applied to an identification device, including:
and S100, acquiring fingerprint information of the terminal.
When the fingerprint information of the terminal is collected by the identification equipment, the fingerprint information can be acquired in an active or passive mode.
In the active mode, the identification device may send a detection message to the local area network, and when the terminal receives the detection message, the identification device may send a feedback message to the identification device. The feedback message carries the characteristic information of the terminal, and the identification device analyzes the feedback message after receiving the feedback message and acquires the fingerprint information of the terminal from the feedback message.
In the passive mode, a message is mirrored on a switch (aggregation switches 20 and 21 in fig. 1) to which the identification device is connected, and a Protocol message sent by the terminal is mirrored to the identification device, where the Protocol message may be a TCP (Transmission Control Protocol)/UDP (User data Protocol) Protocol or an HTTP (Hyper Text Transfer Protocol) Protocol, and the Protocol message also carries characteristic information of the terminal. After the identification device receives the protocol message of the mirror image, the protocol message is analyzed, and the fingerprint information of the terminal is obtained from the protocol message.
The fingerprint information may be a MAC address, an IP address, an operating system identifier, a terminal type, and the like of the terminal, and the fingerprint information acquired by the identification device is referred to as target fingerprint information in the following description. For example, the identification device 10 may acquire fingerprint information of the terminal 41 that it hangs down.
S101, when the acquired fingerprint information is not matched with the fingerprint information stored in the first fingerprint library, the acquired fingerprint information is stored in a second fingerprint library.
The identification device is provided with a first fingerprint library and a second fingerprint library, wherein the first fingerprint library can be called a baseline fingerprint library and is a relatively stable fingerprint library and used for storing the fingerprint information of the identified and adapted terminal, the identification device cannot update the first fingerprint library by itself, and the second fingerprint library can be called a new terminal fingerprint library and used for storing the fingerprint information of the newly accessed terminal collected by the identification device.
And after the identification equipment acquires the target fingerprint information, matching the target fingerprint information with the fingerprint information stored in the first fingerprint database. If the target fingerprint information is matched with the fingerprint information in the first fingerprint database, the terminal can be considered as a terminal which is on-line before, and the terminal does not need to be sent to a cloud platform for updating; if the target fingerprint information does not match the fingerprint information of the first fingerprint repository, storing the target fingerprint information in a second fingerprint repository. That is, the identification device 10 may temporarily store the fingerprint information of the terminal 41 in the second fingerprint repository.
S102, sending the acquired fingerprint information to a cloud platform so that the cloud platform can update according to the received fingerprint information and send fingerprint database update information to identification equipment communicated with the cloud platform.
After the target fingerprint information is stored in the second fingerprint library, the identification device sends the target fingerprint information to the cloud platform. The cloud platform can carry out operation and authentication according to the received fingerprint information, and updates a fingerprint database maintained by the cloud platform, wherein the fingerprint database is used for managing the fingerprint information sent by the identification equipment communicated with the cloud platform, and after the fingerprint database is updated, the fingerprint database update information is issued aiming at the identification equipment registered on the cloud platform.
In the networking shown in fig. 1, the identification device 10 may upload the fingerprint information of the terminal 41 to the server 60 in the cloud platform, and in the networking, the cloud platform may include two servers 60 and 61, and the server 60 performs maintenance of the fingerprint library of the cloud platform. The fingerprint library of the cloud platform may be implemented in the server 60, or may be implemented by a separate storage device, which is not limited thereto.
S103, updating the first fingerprint database according to the received fingerprint database updating information.
And after the identification equipment receives the fingerprint database updating information, acquiring the fingerprint information contained in the fingerprint database updating information to update the first fingerprint database. Therefore, the process that the identification equipment identifies and adapts to the newly accessed terminal can be realized, the first fingerprint library is a stable fingerprint library, before the terminal is identified and authenticated in the networking, the influence on the first fingerprint library is reduced as much as possible, therefore, the second fingerprint library is introduced to store the fingerprint information of the new terminal, and after the fingerprint information of the new terminal is updated in the fingerprint library of the cloud platform, the cloud platform uniformly updates the first fingerprint library to the plurality of identification equipment, so that repeated identification and updating among the plurality of identification terminals are avoided, and the efficiency of terminal identification in the networking is improved.
Moreover, after the networking authenticates the newly accessed terminal, the cloud platform uniformly updates the newly accessed terminal, and the condition that fingerprint information which is not authenticated and possibly has an abnormal terminal is written into a fingerprint library can be avoided, so that the networking is attacked by the abnormal terminal is avoided.
That is, in the networking of fig. 1, when the server 60 completes updating of the fingerprint repository, the fingerprint repository update information may be transmitted to the identification device 10 and the identification device 11, so that the identification devices 10, 11 update the first fingerprint repository, respectively.
Further, after step S103, the method further includes:
and S104, deleting the fingerprint information contained in the update information of the fingerprint database from the second fingerprint database.
After the identification device updates the first fingerprint library according to the fingerprint library update information issued by the cloud platform, the fingerprint information carried in the fingerprint library update information can be deleted from the second fingerprint library, so that the fingerprint information of the identified terminal is prevented from occupying the space of the second fingerprint library.
In addition, the identification device can also periodically send the target fingerprint information in the second fingerprint library to the cloud platform to assist other identification devices in the networking to update the fingerprint information of the terminal, so that the identification device can also periodically delete the fingerprint information in the second fingerprint library to avoid the fingerprint information updated to the first fingerprint library from occupying the storage space in the second fingerprint library. Generally, the defined erase period needs to be greater than the upload period for the identification device to upload the fingerprint information stored in the second fingerprint repository.
Since the fingerprint information of the terminal 41 is acquired by the identification device 10, the identification device 10 can search the fingerprint information of the terminal 41 from its second fingerprint database and delete the fingerprint information after receiving the fingerprint database update information. However, after the first fingerprint library is updated, since the fingerprint information of the terminal 41 is not stored in the second fingerprint library, the identification device 11 cannot be matched with the second fingerprint library according to the fingerprint information of the terminal 41, and further no further processing is required.
Correspondingly, the present application provides a terminal identification method, as shown in fig. 3, which is applied to a server in a cloud platform, and includes:
s200, receiving fingerprint information sent by the identification equipment.
S201, updating a fingerprint database in the cloud platform according to the fingerprint information.
The cloud platform can be composed of a plurality of servers, the cloud platform can be realized by any one server in the cloud platform, and of course, other servers can have the same or similar functions. That is, the terminal identification method may be simultaneously/separately implemented on the server 60 and the server 61.
After receiving the fingerprint information sent by the identification equipment, the server in the cloud platform carries out operation and authentication according to the fingerprint information, and updates a fingerprint database maintained by the cloud platform after the authentication. The fingerprint repository may correspond to a baseline fingerprint repository of the identification device, with fingerprint repository update information being generated from fingerprint information in the fingerprint repository. The fingerprint database update information may be issued in the form of a segment of address, for example, an address based on the HTTP protocol or the HTTPs protocol, where the identification device may access the fingerprint database of the cloud platform to obtain the fingerprint database update information. Alternatively, the fingerprint database may be directly updated, and the like, and is not limited herein.
Taking an address of a segment of HTTP protocol as an example, the update information of the fingerprint database issued may be an update address carried in a message. After the identification devices 10 and 11 receive the message, the message is analyzed to obtain the update address, and access is performed according to the update address, so that the fingerprint information contained in the fingerprint library updated by the cloud platform is obtained, and the first fingerprint library is updated according to the fingerprint information, so that the unified update of the first fingerprint libraries of the identification devices 10 and 11 is realized.
S202, sending fingerprint database updating information to the identification equipment registered in the cloud platform, so that the identification equipment updates the first fingerprint database of the identification equipment according to the fingerprint database updating information.
In the process of applying the cloud platform, the identification device needs to be registered with the cloud platform to determine the validity of the identification device.
After a server in the cloud platform updates the fingerprint database, the fingerprint database update information is sent to the identification device registered on the cloud platform. After the identification equipment receives the fingerprint database updating information, the fingerprint database updating information is analyzed to obtain the fingerprint information carried in the fingerprint database updating information, and the first fingerprint database in the identification equipment is updated.
In order to improve the flexibility of updating and avoid the influence of the update of the fingerprint library on the operation of the identification device, further, step S202 may include:
S202A, when the system time reaches a preset time range, fingerprint database updating information is sent to the identification device registered in the cloud platform.
A server in the cloud platform runs system Time, and the system Time is acquired based on a PTP (Precision Time Protocol) Protocol, or may be set in the server.
The server of the cloud platform can be further provided with a preset time range, the server receives fingerprint information of the terminal and updates the fingerprint library outside the time range, when the preset time range is reached, the fingerprint library updating information can be generated according to the fingerprint information maintained in the current fingerprint library and is issued to the identification device, so that the first fingerprint library of the identification device hung below the server is periodically updated, the phenomenon that the identification device is greatly output and processed due to too frequent updating of the first fingerprint library is avoided, and the situations that the terminal identification is wrong due to instability of the first fingerprint library and the like can also be avoided.
