Description
Technical Field
The invention relates to the field of archive management, in particular to an archive management system based on a block chain.
Background
With the advent of the digital and digital assets, data becomes one of the most valuable assets at present, and archives as carriers of a large amount of original data not only have the requirements of using, looking up and archiving, but also have the potential of data mining and analyzing. In order to meet the requirement, the file digitization processing industry has come to work, and the national organs also make clear requirements on file digitization. However, not only does the digital processing of the archive require a large amount of manpower and material resources, but also the confidential documents are easy to leak, the electronic documents are easy to make mistakes and easy to be tampered, the generated electronic archive cannot be used for data mining and analysis, and the archive generation process cannot be traced. Therefore, the utilization rate and the attention degree of the file information are low at present, and large data application cannot be performed, and massive file data mining application becomes a necessary requirement for the development of the current time. The management and application of electronic files have many disadvantages. The electronic files are stored, and due to the influence of hardware equipment and other reasons, the electronic files need to be subjected to multiple backup, so that the loss of file data is prevented. The second is the safety problem of the electronic file, because the information resource of the electronic file is shared and transmitted by using the network, the network has a very wide audience, anyone can steal the information therein or even tamper the information by corresponding technical means, and the network is an unstable factor. Finally, the authenticity and the integrity of the file are realized, the file is easy to miss and tamper in the informatization process of the file management department, no trace is left, the authenticity cannot be guaranteed, and meanwhile, the file is incomplete due to hardware equipment when the electronic file is stored in different formats.
Disclosure of Invention
In view of the above, an object of the present invention is to provide a block chain-based file management system, which can prevent a file from being tampered, prevent information leakage of a confidential file, and facilitate information mining, analysis and application of the file.
The purpose of the invention is realized by the following technical scheme:
block chain based archive management system comprising:
the data stream management system is used for managing each archive forming process;
the database is used for storing the original data file of each node in the forming process of each file;
the block chain is used for storing the original data file, the hash value and the electronic signature of each node in the forming process of each file, each file is separately stored in a father block, the original data file, the hash value and the electronic signature of each node in the forming process of each file are separately stored in a sub-block below the father block, and each file in the block chain is classified according to the confidentiality requirement;
the comparison system is used for regularly comparing the block chain with the original data file on the database, and alarming and sending alarm information to the client if the block chain is inconsistent with the original data file on the database;
the sandbox system comprises sandboxes with different security levels, the sandbox system is in data butt joint with the block chain, and the sandboxes with different security levels receive files with corresponding security levels;
and the user intervenes in the sandbox through the client to perform archive management, query and/or operation.
Further, the file formation process is as follows: saving files, submitting examination and approval, examining and approving files and filing files.
Furthermore, the client comprises a desktop client, a browser client and a mobile client.
The invention has the beneficial effects that:
the file management system based on the block chain can prevent files from being falsified by setting the block chain distributed storage files, can warn the files from being falsified by setting the comparison system to regularly compare the block chain with original data files stored in the database, and can change back and improve the encryption level in time, and enables a user to manage, inquire, analyze, mine and apply the files in the sandbox system through a client by setting the sandbox system.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof.
