Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the invention. As used herein, the singular forms also are intended to include the plural forms as well, unless the context clearly indicates otherwise, and it should also be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of the features, steps, operations, devices, components, and/or combinations thereof.

The embodiments and features of the embodiments of the present invention may be combined with each other without conflict.

Example one

The embodiment discloses an information query method based on a Wi-Fi network tree model, which is suitable for Wi-Fi detection equipment, a Wi-Fi sniffer, notebook Wi-Fi software, third-party scanning software of Wi-Fi under LINUX equipment and the like, and aims to realize authority control in a Wi-Fi data query process. The method specifically comprises the following steps:

step 1: Wi-Fi underlying data is captured.

The Wi-Fi underlying data includes information such as an AP (server), an STA (client), 2.4G (all information of 2.4G), 5G (all information of 5G), RSSI (signal strength), CHANNEL, MANU (manufacturer), and MAC (MAC address of device).

Step 2: and organizing the Wi-Fi bottom layer data based on a tree structure to obtain a Wi-Fi network tree model.

The Wi-Fi network tree model meets the following conditions: each path from the root node to the leaf node comprises all fields contained in Wi-Fi underlying data.

In this embodiment, as shown in fig. 2, in the tree structure, the layer 1 node below the root node includes a node representing a wireless Wi-Fi frequency band, such as 2.4G, 5G, and the like; each node of the layer 1 comprises a plurality of layer 2 nodes which respectively represent working modes, such as AP, STA and the like, each layer 2 node comprises a plurality of layer 3 nodes, and the layer 3 nodes under the layer 2 STA nodes respectively represent a Wi-Fi signal channel (channel) and whether a client is on-line (CON); the layer 3 nodes under the layer 2 Wi-Fi signal channel nodes comprise whether the client is on line (CON) or not and Wi-Fi protocol version (PRO); and the layer 3 node below the layer 2 wireless network card configuration node comprises a Wi-Fi signal channel (channel), a Wi-Fi protocol version (PRO) and the like.

And step 3: and acquiring query configuration information, wherein the query configuration information comprises field display conditions, and retrieving the Wi-Fi network tree model according to the configuration information to obtain a target tree model meeting the field display conditions.

The field display condition comprises one or more fields and can also comprise values of one or more fields. For example, if all the 6-channel information of the AP service end under 2.4G needs to be acquired, the configuration information may be written in the following "2.4G AP 6", and for example, if the information of all the STA service ends under 5G needs to be acquired, the configuration information may be written in the "5G STA".

The query method can be configuration file, IPC (process communication) control query, or voice query. When the information is IPC (process communication) control query, the IPC communication data is converted, the IPC data is written into a configuration file, and the information is analyzed. When the mode is voice query, after voice information is identified, the voice information is written into a configuration file, and then the information is analyzed.

Retrieving the Wi-Fi network tree model according to the configuration information comprises:

if the field display condition only comprises one field, searching from the root node of the Wi-Fi network tree model layer by layer downwards, and after the field is searched, taking the field as the tree model of the root node as a target tree model;

if the field display condition comprises a plurality of fields, searching a first field from the root node of the Wi-Fi network tree model layer by layer downwards to obtain all paths comprising the first field, then searching a second field on all paths comprising the first field to obtain all paths comprising the second field, and so on until the last field is searched to obtain the tree model meeting the field display condition.

For clarity of explanation of step 3, reference is made to fig. 2, which illustrates the following:

(1) if the field display condition is 2.4G, the target TREE model is a TREE structure taking 2.4G as a root node, and the corresponding graph shows [ root node ] [2.4G ], and the corresponding data structure is TREE [2.4G ];

(2) if the field display conditions are 2.4G and STA, the target tree model takes 2.4G as a root node and STA as a first-layer node and comprises a tree structure of all nodes below the STA, which corresponds to the [ root node ] [2.4G ] [ STA ] shown in the figure. The corresponding data structure is TREE 2.4G ] [ STA ];

(3) if the field display conditions are 2.4G, STA and the sixth CHANNEL, the target TREE model is [ root node ] [2.4G ] [ STA ] [ CHANNEL6] shown by the corresponding graph, and the corresponding data structure is TREE [2.4G ] [ CHANNEL6 ];

(4) and if the field display conditions are 2.4G, STA, a sixth CHANNEL and online, the field display conditions correspond to those shown in the figure [ root node ] [2.4G ] [ STA ] [ CHANNEL6] [ con ]. The corresponding data structure is TREE [2.4G ] [ CHANNEL6] [ con ];

(5) if the field display conditions are 2.4G, STA, a sixth CHANNEL, online and ESSID, corresponding to [ root node ] [5G ] [ STA ] [ con ] [ CHANNEL ] [ 6] [ ESSID ] shown in the figure, and the corresponding data structure is TREE [5G ] [ STA ] [ con ] [ CHANNEL6] [ ESSID ];

(6) if the field display condition is 5G, RSSI-30-50 and off-line, then the query mode is [5G ] [ RSSI-30-50 ] [ con ].

Because each path from the root node to the leaf node of the initial network tree structure comprises all fields contained in Wi-Fi bottom layer data, all possible query combinations are covered, and displayable fields and conditions can be flexibly configured no matter which field starts to be retrieved.

And 4, step 4: and receiving a user query request, and querying according to the target tree model to obtain related information.

Because the query is carried out in the data range contained in the target tree model, the query control of the data is realized, and the leakage of sensitive information is avoided.

Through the random combination of the tree trunks in the tree model, any information can be searched, the field information is randomly hidden, a search interface program does not need to be independently written, and the search efficiency is improved. And meanwhile, secondary development of data is facilitated, for example, the data is directly displayed on a human-computer interaction interface for data analysis.

through configuring the queriable tree model, the query efficiency can be improved, after query information is received, the device is only responsible for collecting information in the target tree model, other information can be automatically filtered, additional filtering of data is not needed for WI-FI information, the redundancy problem caused by more query information is avoided, and the efficiency of device operation is improved.

And, it is also beneficial to improve the data security, for example, in a common security scenario, a MAC address under a protection terminal, if it is necessary to check how many STAs (clients) exist under an AP (server), it is desirable to check the connection number of the STAs (clients), or RSSI (signal strength indicator, etc.), but the MAC (address) of the device belongs to important information and cannot be revealed. The query configuration information may be configured to: "AP RSSI MAN" represents the number of connections, device vendor, etc. showing all clients under the AP, but the MAC address auto-filter is hidden.

The secondary development can be carried out through the output data, and the obtained data is sent to a third party platform through IPC communication, such as: the data are sent to some embedded devices through mobile phones, computers, panels and the like or through serial ports, USB ports and the like to carry out secondary development of data.
