Embodiment Construction

[0021] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0022] combine figure 1 Shown: the present invention provides a kind of mobile phone number feature keyword automatic extraction method under the fixed network WiFi environment, and described method comprises the steps:

[0023] 1. Construct the perception, analysis and extraction environment of mobile phone number feature keywords in the fixed network WiFi environment: including the passive sensing device and the centralized analysis and extraction center in the fixed network WiFi environment. The passive sensing device and the AP in the WiFi environment are deployed under the same LAN switch, and obtain all the service traffic entering / exiting the AP through port mirroring / light splitting, etc., and analyze the service packets through DPI to obtain necessary information. The analysis and extraction center is deployed in a unified and centralized...

Abstract

The invention discloses an automatic cell phone number characteristic keyword extraction method under a fixed network WiFi environment and relates to the technical field of network security auditing and traffic management analysis. On the basis of utilizing the high-speed parallel keyword searching and matching ability of hyperscan, accuracy of a result is improved through the data association analysis of a time dimension and a spatial dimension, and the automatic extraction of cell phone number characteristic keywords is realized. The invention is applicable to the automatic extraction of corresponding characteristic keywords of other numbers or figures similar to cell phone numbers under the WiFi environment.

Description

technical field [0001] The invention relates to the technical field of network security auditing and flow management analysis, in particular to a method for automatically extracting characteristic keywords of mobile phone numbers in a fixed network WiFi environment. Background technique [0002] Accurate identification and classification of Internet applications is the premise and foundation of network behaviors such as network traffic engineering, network management and security monitoring, network design and planning. With the emergence of home-built WiFi and free WiFi, more and more mobile terminals (especially mobile terminals) access fixed broadband Internet through WiFi to obtain mobile Internet content. Through the analysis and identification of network traffic, communication network operators can achieve the purpose of network security audit and traffic management analysis. Currently commonly used Internet traffic identification and classification methods include: p...
