Problems solved by technology

[0003] The data extraction devices in traditional laboratories are all PC workstations, and use the USB interface for data extraction; this requires that the mobile phone or mobile media be taken back to the laboratory for data extraction, but in actual working conditions, it is required to be able to extract data in various Mobile point, extracting data from mobile phones and mobile media of relevant mobile personnel for rapid retrieval and investigation. Traditional laboratory solutions cannot meet the requirements
At present, there are also data extraction software installed on laptops or tablet computers in the market to achieve mobile operations, but such a working method requires the staff to carry a laptop computer for mobile collection, which is not very concealable and does not have portability
[0004] In addition, for Android mobile phones, the traditional wired acquisition method must enable the mobile phone debugging mode, and different brands of Android mobile phones have different ways to enable the debugging mode, and non-professionals often cannot open the debugging mode
And long-term USB cable contact, the device will charge the mobile phone, which will shorten the battery life of the data extraction device, which is not conducive to the development of mobile data extraction
[0005] Moreover, for single-channel USB and single-channel Wi-Fi devices, it is impossible to extract data from multiple mobile phones at the same time, the efficiency is relatively low, it cannot meet the requirements of fast data extraction, and the timeliness is poor; and when performing Wi-Fi data At the same time of extraction, it is not compatible with USB for data extraction of wired iPhone and other brand mobile phones and mobile media

Embodiment 1

[0083] Please refer to figure 2 , Embodiment one of the present invention is: a kind of multi-channel data extraction method, can be applied to carrying out data extraction to a plurality of Android mobile phones simultaneously, comprises the steps:

[0084] S101: The device side establishes wireless communication connections with multiple mobile terminals through Wi-Fi, and allocates one-to-one corresponding IP addresses for the multiple mobile terminals. The device end is the data extraction device, which can be implemented based on an Android dedicated machine. The device side allocates IP addresses for multiple mobile terminals connected to it, and these mobile terminals can be distinguished subsequently according to the IP addresses.

[0085] S102: The device hijacks the DNS request sent by the mobile terminal, and returns the IP address of the device to the mobile terminal;

[0086] Specifically, the mobile terminal accesses any website through a browser to generate a...

Embodiment 2

[0097] Please refer to image 3 , this embodiment is a further extension of Embodiment 1. On the basis of multiple wireless connections, one USB cable is provided to connect a mobile terminal or a mobile medium at the same time, and the method for extracting data from the mobile terminal or the mobile medium includes the following steps:

[0098] S201: The device side establishes a wired communication connection with a mobile terminal or a mobile medium through USB;

[0099] S202: The device side sends a data extraction request to the mobile terminal or mobile medium;

[0100] S203: The mobile terminal or mobile medium extracts corresponding data according to the data extraction request, and returns the corresponding data to the device;

[0101] S204: The device side parses the corresponding data.

[0102] When the data extraction is complete, disconnect the USB connection.

[0103] This embodiment extracts data through a compatible USB cable, and can extract data from oth...

Embodiment 3

[0105] This embodiment is a multi-channel data extraction system corresponding to the above-mentioned embodiments, including a device end and a plurality of mobile terminals, and the device end includes a wireless router component, a data hijacking component, a DNS service component, an HTTP service component and a data extraction service Components, the mobile terminal includes a browser component;

[0106] The wireless router component is used to establish a wireless communication connection with the plurality of mobile terminals, and assign one-to-one corresponding IP addresses to the plurality of mobile terminals;

[0107] The browser component is used to access any URL and generate a DNS request;

[0108] The data hijacking component is used to hijack the DNS request and redirect the DNS request to a preset first port;

[0109] The DNS service component is used to monitor the first port of the device end, receive the message of the DNS request, obtain the website visited...

Abstract

The invention discloses a multi-path data extraction method and system. The method includes the following steps: a device end is in wireless communication connection with a plurality of mobile terminals via Wi-Fi, and allocates corresponding IP addresses to the mobile terminals; the device end hijacks DNS requests sent by the mobile terminals, and returns the IP address of the device end to the mobile terminals; the mobile terminals send HTTP requests according to the IP address of the device end; the device end receives the HTTP requests sent by the mobile terminals, and returns the downloading address of a data extraction program to the mobile terminals; the mobile terminals download the data extraction application program according to the downloading address, and install and start the data extraction application program after downloading; and the mobile terminals extract data through the data extraction application program, and send the extracted data to the device end. Data of multiple target mobile phones can be extracted simultaneously, and the efficiency of data extraction is greatly improved. Moreover, the concealment performance is strong, and the portability is good.

Description

technical field [0001] The invention relates to the technical field of data extraction, in particular to a multi-channel data extraction method and system thereof. Background technique [0002] In the era of mobile Internet, mobile phones have become the most personal and commonly used tools and devices for people, and the data they carry are becoming more and more abundant; among them, Android mobile phones, as the mobile phones with the highest market share and the largest annual shipments in the world, affect the entire mobile Internet market.
