Problems solved by technology

The applet can only recognize the active behavior and obtain the wifi connection information corresponding to the active behavior, but cannot identify the device id that opened the applet
However, with the advent of the era of big data and the surge of active users of small programs, the amount of data obtained by small programs is also huge.

Abstract

The invention relates to an equipment identification system based on wifi fingerprint information. The equipment identification system comprises the following steps: S1, acquiring equipment wifi fingerprint information of each equipment gid in M time windows in a preset geographic area range from a first database according to a preset time window; S2, acquiring the applet wifi fingerprint information of the cid of each device in the corresponding M time windows in the preset geographic area range from the second database according to the preset time window; S3, converting the sum into corresponding TF-IDF vectors, wherein the value of i ranges from 1 to X, the value of j ranges from 1 to Y, and the value of m ranges from 1 to M; and S4, obtaining the vector similarity of the sum, and determining a device gid corresponding to each device cid based on the vector similarity of the sum. According to the system, the equipment gid corresponding to the wifi fingerprint information of the applet can be quickly and accurately identified from mass data.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a device identification system based on wifi fingerprint information. Background technique [0002] A small program refers to an application that is developed based on a specific programming language and can be used without downloading and installing. The feature of the applet is that it is easy to use and does not need to be manually installed in the operating system. Usually, small programs rely on large-scale applications in the terminal as a carrier for use. The applet can only recognize the active behavior and obtain the wifi connection information corresponding to the active behavior, but it cannot identify the device id that opened the applet. However, with the advent of the era of big data and the surge of active users of small programs, the amount of data obtained by small programs is also huge. If you want to further develop and analyze the Mini Program, it is nece...
