Embodiment 1

[0016] A blockchain-based offline process evidence collection and evidence storage method, such as figure 1 shown, including the following steps:

[0017] S1. The user requests offline process forensics, and the server sends the offline forensics console installation package to the user.

[0018] The offline forensics console installation package builds a virtual machine operating desktop on the user's computer for the user to operate. The virtual machine operating desktop is a window, and the window provides application icons. When the user clicks on the application icon, the window calls the corresponding application on the user's computer. , and adjust the position and window size of the newly created application window so that it falls into the operating desktop of the virtual machine.

[0019] S2. Build a virtual machine operation desktop on the user's computer for the user to operate, record the user's mouse and keyboard operation process, and record the initial coordin...

Embodiment 2

[0039] A block chain-based offline process evidence collection and evidence storage method, this embodiment further improves the user's operation process collection on the basis of the first embodiment. In this embodiment, the virtual machine operation desktop provides users with a key checkpoint button. When the key checkpoint button is clicked, the desktop image of the virtual machine operation desktop is saved as a key checkpoint, and the user operations before and after the key checkpoint are compared with the key checkpoint. Association, including the key checkpoints of the associated user's previous and subsequent operations into the user operation process file upload server, when the server restores the user's operation process, check whether there is a desktop image that matches the key checkpoint between the associated user's previous and subsequent operations, and if so If the key checkpoint passes, otherwise, the key checkpoint fails, and the user is notified that th...

Abstract

The invention relates to the technical field of blockchain evidence storage, in particular to a blockchain-based offline process evidence obtaining and storing method. The method comprises the following steps that: a server sends an offline evidence obtaining console installation package to a user; a virtual machine operation desktop is constructed for the user to operate, a mouse and keyboard operation process of the user is recorded, a user operation process file is formed and uploaded to the server; the user operation process file is called to construct a virtual machine, the user operation process is restored, and virtual machine desktop images are stored at a certain frequency; the stored desktop images are stored according to a time sequence to form a video, and the video is associated with timestamps so as to be adopted as evidence obtaining data; a preservation certificate is generated, and a compressed data packet is formed; and the compressed data packet is signed and storedand is subjected to digital fingerprint extraction, so that evidence storage data can be formed, the evidence storage data is broadcasted to a block chain network, and anchored to a public block chain. With the method adopted, the concurrent pressure of the server is reduced, the efficiency of the process evidence obtaining of the server is improved, and the process evidence obtaining is more convenient.

Description

technical field [0001] The invention relates to the technical field of blockchain certificate storage, in particular to a blockchain-based offline process evidence collection and certificate storage method. Background technique [0002] The development of the Internet not only brings rich cultural content and information, but also brings the risk of network infringement. Network infringement refers to the right owner's works being used by other Internet users without authorization on the Internet, causing damage to the rights owner's interests. Due to the openness, high update rate and low security of the Internet, network infringement has always been a difficult problem in rights protection and evidence collection for copyright and other related rights. Although the screenshots of the current webpage have been accepted as evidence by the judiciary. However, evidence collection is still very difficult and limited, and it is difficult to obtain evidence for dynamic web page...
