Archives data protection system and method based on block chain technology

Abstract

The invention relates to the field of data storage technology and information security technology, and relates to an archives data protection system and a method based on block chain technology. The system includes a file management system, a RESTful server, a distributed database under block chain, an intelligent contract system on private block chain and an intelligent contract system on publicblock chain. The file management system is used to realize the local management of archives data; the RESTful server is used to realize the data processing between the file management system, the distributed database under the block chain, the intelligent contract system on the private block chain and the intelligent contract system on the public block chain. Distributed database under block chainis used to backup archival data, intelligent contract system on private block chain is used to store summary information of archival data, intelligent contract system on public block chain is used toanchor intelligent contract system on private block chain. The method is realized based on the system, and the invention can improve the security of the file data.

Description

technical field [0001] The present invention relates to the field of data storage technology and information security technology, in particular to a file data protection system and method based on block chain technology. Background technique [0002] With the rapid development of IT technology, people use digital means on a large scale to improve the efficiency of file storage and processing. Compared with traditional paper-based physical archives, digital archives are highly volatile as bits and bytes stored on storage media. During the storage, transmission and processing of digital archives, archive records are easy to be modified without being detected. Therefore, archives Data authenticity and security issues have become hot issues in related fields. The following defects still generally exist in the existing archival data protection methods: [0003] 1. Most of the existing archive data protection methods are realized through the digital fingerprint of the archive. W...

Problems solved by technology

However, this method stores both archive data and archive digital fingerprints in a centralized database. Stakeholders can hire hackers to invade the database and reset the archive digital fingerprint while tampering with the archive data, making it difficult to detect tampering with this method. Behavior

[0004] 2. The existing archival data protection method lacks the protection of the operation records of the archival management personnel. Stakeholders can modify the archival data through the archival management system by buying or coercing the archivist

It is difficult for archive data protection methods to distinguish between normal and malicious archive modification behaviors, and it is also difficult to pursue accountability even after file tampering is discovered

[0005] 3. The existing archival data protection methods lack an effective archival data recovery mechanism, and it is difficult to restore the tampered archive information when an abnormal archive data is detected
