A data transmission method based on wifi connection mode

Abstract

The invention discloses a data transmission method based on a WIFI connection mode. The method comprises the steps of S1, configuring a wireless network card and starting a local area network; S2, starting TCP Listeners for monitoring by a computer side; S3, generating a two-dimensional bar code picture for WIFI connection; S4, establishing a data packet transmission protocol; S5, establishing a data transmission anomaly monitoring module; S6, scanning the two-dimensional bar code picture of the computer side to establish a data transmission channel; S7, appointing a security key for data transmission; S8, designing high-speed cache of receiving data by the computer side; and S9, receiving and analyzing the data by the computer side. The method has the advantages that the WIFI data transmission security is improved; the data transmission stability is ensured; the WIFI transmission speed is high; troublesome file authority modification is avoided, and the usage is convenient; the problem that a mobile phone USB cannot be connected with the computer side is solved; and the capability of carrying out data collection and connection maintenance on multiple devices at the same is realized.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a data transmission method based on a WIFI connection mode. Background technique [0002] In electronic forensics, due to the limitations of the smart phone's own hardware and mobile terminal analysis software, some important data files can only be transferred to the computer terminal and combined with powerful electronic data analysis software to conduct more professional and in-depth analysis of these data Mining Extraction Analysis. Most of the forensics software copies the data on the smartphone to the computer through USB transmission. The following summarizes the shortcomings of transferring to the computer via USB connection: [0003] 1. The hardware conditions for USB transmission are: the USB port of the computer, the USB port of the mobile phone, and the USB cable are in good condition and connected normally. If there is a problem with one of them, the US...

AI Technical Summary

Problems solved by technology

[0003] 1. The hardware conditions for USB transmission are: the USB port of the computer, the USB port of the mobile phone, and the USB cable are in good condition and connected normally. If there is a problem with one of them, the USB transmission cannot be completed.

[0004] 2. The software conditions for USB transmission are: the computer must install the mobile phone connection driver or a third-party mobile assistant, and the mobile terminal must allow operations for data requests, etc. If one party has a problem, the USB transmission cannot be completed.

[0005] 3. During the normal USB transmission process, the transmission is interrupted due to objective factors such as insufficient power supply of the USB port or movement of the device.

[0006] 4. USB transmission requires that the file permissions on the mobile phone must be readable and writable super permissions, and some file permissions cannot be transferred if they fail to be modified.
