The invention provides an intelligent education resource sharing and authority
management system based on a block chain, and belongs to the technical field of intelligent education, and the
system comprises a block
chain network layer, a resource right confirmation module, an intelligent contract module, a distributed storage network, a cross-chain interaction gateway and a dynamic optimization module, comprising a resource
authentication chain, an authority management chain and a cross-chain interaction chain, and the chains realize data intercommunication through
relay nodes; the resource right confirmation module adopts a three-level Hash nested structure to generate a non-tampering
digital fingerprint, and binding and uplink the educational resource
metadata and the creator DID; the intelligent contract module comprises a dynamic authority
management contract and a resource transaction contract, and supports an
access control strategy based on
context awareness. According to the intelligent education resource sharing
system, the core problems that the right of the education resources is difficult to confirm, the sharing efficiency is low, and the right management is inflexible are solved, and the safe, intelligent and extensible intelligent education resource sharing
system is constructed.
