A data storage and preservation processing method and system based on distributed storage technology

By preprocessing the data to be stored and issuing a trusted timestamp, combined with the blockchain consensus mechanism, the fingerprint of the stored evidence is written into the blockchain, which solves the problems of low reliability of the stored evidence timestamp and high cost of putting massive amounts of data on the chain, and realizes independent user verification and data integrity protection.

AI Technical Summary

Technical Problem

Existing blockchain-based data storage solutions suffer from low reliability of storage timestamps, high costs of uploading massive amounts of data to the blockchain, and the inability of users to independently verify data, resulting in low practicality and stability.

Method used

The first-level evidence fingerprint is generated by preprocessing the data to be stored, and a trusted timestamp is issued to a trusted timestamp service provider. The final evidence fingerprint is written into the blockchain in conjunction with the consensus mechanism of the blockchain network, generating an electronic evidence certificate, which can be independently verified by the user.

Benefits of technology

It reduces the cost of evidence preservation, improves the credibility of evidence preservation timestamps, enables independent verification by users, and enhances data integrity and privacy protection.

Abstract

The application discloses a kind of based on distributed storage technology's data storage evidence security processing method and system, its method includes: to the original electronic data of being stored evidence carries out hash operation, obtains first level evidence fingerprint;For first level evidence fingerprint issues trusted timestamp, first level evidence fingerprint, the content identifier of original data is combined with trusted timestamp and carries out hash operation as data packet and generates final evidence fingerprint;Final evidence fingerprint is broadcast to block chain network to generate evidence record;According to electronic evidence certificate, final evidence fingerprint is obtained from block chain network, and secondary hash calculation is re-executed to the original electronic data provided by user, and verification fingerprint is obtained, and verification conclusion of data integrity and evidence time credibility is determined according to the consistency of verification fingerprint and final evidence fingerprint.Reduces the cost of evidence, guarantees the high reliability of evidence timestamp, can be independently verified on the public block chain, effectively protects commercial secret and personal privacy.
