Multi-line evidence obtaining method and device based on block chain, equipment and storage medium

Abstract

The invention discloses a multi-line evidence obtaining method and device based on a block chain, equipment and a storage medium, and belongs to the technical field of block chains. According to the embodiment of the invention, the evidence obtaining request for the target evidence obtaining address is responded to send an evidence obtaining instruction to at least two node devices, therefore, atleast two pieces of video data obtained by recording the content displayed by the target evidence obtaining address by the at least two pieces of node equipment are obtained; the at least two pieces of video data are stored in a local database of the current node equipment, the key information of the at least two pieces of video data is stored in a block chain; the node equipment in the blockchainsystem automatically records the video data and stores the key information to the blockchain, and a multi-line evidence obtaining mode is adopted instead of a client to obtain evidences, so that thelabor cost is reduced, the obtained evidence obtaining data cannot be tampered, the authenticity of the evidence obtaining data can be ensured, and the evidence obtaining efficiency is also improved.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular to a multi-line forensics method, device, equipment and storage medium based on blockchain. Background technique [0002] With the development of technology, the speed of network transmission is getting faster and faster, and people will spread various contents to others through the network for sharing. However, there will be many infringements in this way. For example, some content is put on a certain website for users to browse or download without the original author's permission. At this time, it is necessary to collect evidence and store the obtained data for subsequent rights protection. [0003] At present, the method of obtaining evidence is usually that the parties themselves install the application on the mobile device, and through the application, relevant information such as screenshots or website addresses are sent to a centralized server for storage. ...

AI Technical Summary

Problems solved by technology

[0004] In the above method, the parties collect evidence by themselves and send the results to the server for storage. The labor cost is high, and the efficiency of the evidence collection method is low.

Moreover, the forensic data obtained by the above method is easy to be tampered with, and the authenticity of the forensic data cannot be guaranteed.
