The invention discloses an archive secure storage and sharing
system based on a
hybrid block chain and an implementation method, belongs to the field of archive sharing, and aims to solve the technical problem of how to realize archive
privacy protection, prevent archives from
forging and tampering, enable authorized access of the archives, and improve the archive sharing speed. According to the technical scheme, the
system comprises a storage layer which is used for storing shared files and protecting the files against tampering, and adopts an IPFS; a sharing layer which is used for recordinggenerated transaction information, providing evidences for tracing of the
file sharing process, automatically executing identity
authentication and guaranteeing safe sharing of files under the condition that no
third party participates, and comprises a multi-layer block
chain model and an intelligent contract on a block chain; and a user layer which is used for managing, updating, checking and sharing files, and is composed of participants. The method specifically comprises the following steps: initializing; identity registration and
authentication; encrypting and storing the archives; and archive sharing.
