Problems solved by technology

[0005] 1. Since the evidence collection (evidence fixation) of the website needs to involve evidence fixation scripts, and evidence fixation scripts need professional and technical personnel to write, it is difficult for law enforcement agencies, and it is difficult to write by themselves, and it is necessary to seek the help of relevant technical personnel
However, technicians need to spend time writing codes and testing to write scripts, which greatly prolongs the time for obtaining evidence, which may lead to missing the best opportunity for obtaining evidence, or even failing to obtain evidence
[0006] 2. The content of the website is updated frequently, so that the customized script needs to be updated immediately. If it is not updated, the previously written evidence fixation script will no longer be valid, and evidence fixation cannot be performed
However, when the website is updated, it is difficult for us to know in time. Even after knowing, the code needs to be re-modified, and this process still requires professional and technical personnel to perform
[0007] 3. The data capture is not smart enough. The data capture of the existing technology is based on web page analysis or data interface monitoring, and usually different interfaces of the same website need to customize scripts one by one to extract the data, which is not flexible enough
Once the structure or interface of the web page is changed, professional and technical personnel are required to re-develop the script

[0036] figure 1 A general flowchart of the method provided by the present invention is shown. Such as figure 1 Shown, method of the present invention comprises the following steps:

[0037] S100: use the WebSocket protocol to establish communication with the Chrome browser and monitor the user's operations on the Chrome browser, including keyboard input, keyboard shortcuts, mouse clicks, mouse wheel scrolling, inputting text, scrolling pages, and file downloads;

[0038] S200: Enter the address of the forensic webpage in the address bar of the Chrome browser to enter the forensic page; it is worth noting that some websites need to log in first before entering the forensic interface; at this time, the operator needs to log in by himself, and then jump to Forensic page.

[0039] S300: Determine whether data needs to be extracted, if yes, execute step S400, otherwise execute step S500;

[0040] S400: Extracting data, including: judging whether the automatic recognition result...

Abstract

The invention discloses a webpage evidence obtaining and data extraction method based on a Chrome browser debugging protocol. The method comprises the following steps: S100, establishing communication with a Chrome browser by adopting a WebSocket protocol, and monitoring the operation of a user on the Chrome browser; S200, inputting an address of a forensic webpage in an address bar of the Chrome browser, and entering a forensic page; S300, judging whether data needs to be extracted or not, if yes, executing the step S400, and if not, executing the step S500; S400, extracting data: judging whether an automatic identification result contains to-be-acquired data, an automatic identification result, manual configuration data and data acquisition; S500, adopting a CDP debugging protocol of the Chrome browser, performing recording and recording operation of a user on the Chrome browser, and performing corresponding screen capture on the web page; S600, ending the operation recording mode, and configuring and / or editing the recorded operation list; S700, playing back the configured and / or edited operation list, and executing playback in sequence according to the operation list; and S800, after playback is completed, generating an evidence obtaining result.

Description

technical field [0001] The invention belongs to the field of electronic evidence collection, and relates to a method for capturing webpage screenshots and extracting data, in particular to a method for obtaining webpage evidence and data extraction based on a Chrome browser debugging protocol. Background technique [0002] Hypertext (also known as webpage) is a network text that organizes text information in various spaces together by hyperlinks. It is displayed by a program called a web browser (Web browser). Wide range of technologies. [0003] Although the Internet plays an important role in people's work and life, and the content of the Internet is colorful, the Internet is also used by criminals involved in crimes such as pornography, gambling, and fraud. With the popularization of the Internet, there are more and more websites with illegal content, and there is an urgent need for an effective method to collect evidence and extract data from web pages, so as to achieve...
