Method for generating and loading specific project files based on WPF (Windows Presentation Foundation) technology

Abstract

The invention relates to a method for generating and loading specific project files based on a WPF (Windows Presentation Foundation) technology. The method comprises the following steps: saving backup of source data; compressing the source data in a zip way; obtaining the MD5 value of a file; reversely processing all hexadecimal bytes; setting a name suffix and carrying out core encryption processing; loading a case project file; reversely decrypting the project file; extracting valid data from the source data; and accurately displaying the data by combining a WPF display technology with a map and a timeline. The method provided by the invention has the beneficial effects that the project file is a single file to facilitate the loading and displaying of project data; a case project in a single file way is better than a case project in a folder way when mobile data is copied; the integrity of the project file is ensured and the project file is prevented from being tampered by using a unique multi-encryption way; the universality is strong, and the transplanting is convenient; a WPF interface is more concise and intuitive, and is easily studied and judged.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for generating and loading specific project files based on WPF technology. Background technique [0002] Most of the friends in the field of mobile phone forensics use the project storage method: the data table inside the program is directly serialized into files in xml format or json format, and then these files are saved in a unified folder (that is, the case folder ), set a project file for case loading in this folder, load this file directly when loading a case, and then retrieve other data files in the current folder to achieve the purpose of loading previous cases. The generation and loading of such project files have the following risks: [0003] 1. For case projects in the forensics industry, directly save the extracted data as files in plain text, the content is easy to be tampered with, and the authenticity of the case cannot be guaranteed; [00...

AI Technical Summary

Problems solved by technology

[0003] 1. For case projects in the forensics industry, directly save the extracted data as files in plain text, the content is easy to be tampered with, and the authenticity of the case cannot be guaranteed;

[0004] 2. The case exists in the form of a folder, and the files in the folder are easy to lose, resulting in failure to load the case project or the content of the case project is incomplete;

[0005] 3. Most of the loading project data is automatically executed inside the program, and it is impossible to manually choose to load project files saved by other computers, and the project flexibility is low;

[0006] 4. Only the data collection displayed on the program interface is saved, and the original files backed up from the device are not saved, which cannot be used as key evidence for forensics

At present, the ZIP format is one of several mainstream compression formats. In terms of performance, the RAR format has a higher compression rate than the ZIP format, but its compression time is much higher than that of Zip.
