Ownership registration method, ownership proof method and device based on blockchain

Abstract

The embodiment of the invention provides an ownership registration method and an ownership proof method based on blockchain. An execution main body of the ownership registration method is in a blockchain network is a node corresponding to the ownership registration platform; the method comprises the steps that based on an ownership registration request sent by a user for a target work, a hash value corresponding to the target work is obtained, then a transaction is issued in a block chain, the transaction comprises identification information of the user and the hash value, and the transactionis recorded in a block of the block chain. Thus, the timestamp, the user identification information recorded in the block and the hash value are generated through the block of the block, and recordingof a certain work owned by a certain user at a certain time point is completed. In addition, in the ownership proof method provided by the invention, the node corresponding to the notarization position in the blockchain network can find the block recording the hash value according to the hash value of the target work to be proof, so that the notarization of the ownership of the target work is completed.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of blockchain, and in particular to a method and device for registering ownership based on blockchain, and a method and device for proving ownership based on blockchain. Background technique [0002] At present, the field of copyright (also known as copyright) involves multiple links, including copyright registration and management of works, infringement detection, notarization and evidence collection, judicial rights protection mediation and litigation, etc. Each of these links is relatively independent, and some of them are particularly dependent on offline processing. In the process of rights protection, it also involves the transfer between different links, which leads to high recovery costs and low efficiency for copyright owners, which is not conducive to the cultivation of copyright awareness to a certain extent, and is not conducive to stimulating everyone's creativity....

AI Technical Summary

Problems solved by technology

In the process of rights protection, it also involves the transfer between different links, which leads to high recovery costs and low efficiency for copyright owners, which is not conducive to the cultivation of copyright awareness to a certain extent, and is not conducive to stimulating everyone's creativity

[0003] In the final analysis, the reason for the cumbersome business process in the field of copyright, etc. is that it is difficult to guarantee the reliability, security, and usability of copyright registration data, etc.
