The invention discloses an archive
management system based on a block chain, and the
system comprises a data
flow management system which is used for the management of each archive forming process; a
database which is used for storing an
original data file of each node in the forming process of each file; a block chain which is used for storing an
original data file of each node and a hash value and an
electronic signature of each node in the forming process of each file, wherein each file in the block chain is subjected to security classification according to a security requirement; a comparison
system which is used for regularly comparing the consistency of the block chain and the
original data file on the
database, and if not, giving an alarm and sending alarm information to the
client; a sandbox system which comprises sandboxes with different security classifications, wherein the sandbox system is in
data connection with the block chain, and the sandboxes with the different security classifications receive the archives with the corresponding security classifications; and a user which intervenes in the sandbox through the
client to perform archive management, query and / or operation. The system can prevent files from being tampered, can avoid
information leakage of confidential files, and can facilitate file
information mining and application.
