An electronic data dynamic hash chain consensus storage system and method thereof

Abstract

The invention discloses an electronic data dynamic hash chain consensus storage system and a method thereof. The system comprises a plurality of consensus nodes and a consensus network. The pluralityof forensics servers dynamically record the electronic data hash value and the audit data hash value generated by each forensics document when the forensics device is forensics. The hash value of thedynamic chain record is granted with a trusted timestamp by the trusted timestamp service center to become uplink information. The plurality of forensics servers send uplink information to the only forensics node and the forensics node through the consensus network. Each of the certificate-only nodes, wherein the certificate-storing node reaches an uplink consensus on the uplink information according to the system rules and stores the uplink consensus and the uplink information into a data packet and stores the data packet and the uplink information to the plurality of forensic servers. The authenticity, integrity and legitimacy of the electronic data are ensured through the dynamic hash chain certification method.

Description

technical field [0001] The invention relates to the technical field of electronic data forensics, in particular to a dynamic hash chain consensus storage system and method for electronic data. Background technique [0002] In today's judicial forensics, the form of evidence is increasingly converted from traditional documentary evidence and physical evidence to electronic evidence. However, due to the nature of electronic evidence, which is easy to be lost and tampered with, it is not easy to preserve. Therefore, it is proposed from the state to the local level that a third-party legal organization with relevant qualifications should store the evidence. The deposit of evidence by third-party organizations is often accompanied by disputes, such as: insufficient authority, insufficient effectiveness, legal risks and other issues. The existing certificate deposit method of qualified tripartite institutions is to store electronic data in the form of backup on their own institut...

AI Technical Summary

Problems solved by technology

In some cases, such as backup server damage or server hacking, electronic data is easily destroyed

When the above accident occurs, the electronic data is likely to be discarded and cannot be admitted as evidence

Moreover, electronic data may cause faults, breakpoints, and incomplete evidence during the transmission process.

There is no way to effectively circumvent the accepted data in the existing evidence storage methods. In legal practice, a single or partial electronic evidence is not enough to support the judgment of the entire case
