Abstract

The invention claims a digital copyright registration technology based on a block chain, and particularly aims at the technical field of block chains. The method comprises the following steps: a) issuing an identity certificate to generate a copyright account so as to realize identity auditing and access control; B) storing the digital works by the IPFS; C) the client initiates a copyright registration proposal; D) the endorsement node verifies the identity of the client, executes a copyright registration contract, carries out endorsement signature and returns a response; E) the ordering nodeverifies the endorsement signature, orders the proposals, packages the proposals into blocks, and broadcasts the blocks to the whole network; And f) the accounting node synchronizes the blocks and updates the account book. According to the method, contract execution and consensus are separated, node functions are decoupled, and the copyright registration efficiency is improved. And then copyrightregistration and access control are realized through an intelligent contract, and an authorized user can access personal copyright information, so that the privacy of data is ensured. And finally, thelarge file storage problem of the block chain is solved through a chain-on-chain-off combination mode, work indexes, creator identities and the like are recorded on the chain, and digital works are stored through an IPFS under the chain.

Description

technical field [0001] The invention belongs to the technical field of block chain, and specifically relates to the separation of contract execution and consensus, block chain nodes perform different functions according to distribution, and improve the efficiency of copyright registration. At the same time, copyright registration information recording and access control are realized through smart contract technology in the blockchain. Only authorized users can access personal copyright information, which ensures the privacy of personal data and enhances the security of copyright registration. Finally, the problem of large file storage in the blockchain is solved through the combination of on-chain and off-chain. Copyright registration information is recorded on the blockchain, including work index information, creator identity information and registration time, etc., and IPFS is used to store digital data under the blockchain. work. Background technique [0002] As numbers ...
