Research On Copyright Protection Of Fine-grained Digital Educational Resources Based On Blockchain

With the realization of the phased results of China’s education informatization layout and the completion of the national construction of the public service platform of education resources,the problems in the development of digital education resources also appear,and the increasingly serious copyright problem is one of them.Blockchain technology is considered as a natural fit with copyright protection due to its characteristics of non tampering,easy to deposit and high credibility.In recent years,a lot of research has been carried out,but the current copyright protection system based on blockchain mainly has the following problems:first,the existing system does not carry out fine-grained copyright deposit,resulting in insufficient evidence for rights protection;Second,the form of copyright transaction is single,which does not support the copyright transaction in the multi-user scenario;Third,the scope of copyright authentication supervision is limited to a single platform,which affects the effect of authentication supervision.In order to solve the above problems,this paper takes the fine-grained copyright protection of digital education resources as the starting point,summarizes the specific copyright protection requirements of the storage,transaction and supervision links through detailed demand analysis,and constructs a fine-grained copyright protection system of digital education resources in the field of education,and uses the blockchain,digital fingerprint,intelligent contract,encryption technology,encryption technology Alliance chain and other means to design a digital education resources copyright protection chain with complete functions and better performance.The main work of this paper is as follows(1)By analyzing the current situation of copyright protection of digital education resources in the links of copyright preservation,copyright trading and authentication supervision,the specific needs of copyright protection of digital education resources in various scenarios are summarized.(2)In order to meet the needs of copyright protection of digital education resources,this paper proposes a fine-grained copyright protection architecture based on the characteristics of knowledge and multi granularity of digital education resources Under the support of multiple scenarios,the copyright transaction of digital education resources and the collaborative supervision of digital education resources copyright alliance are carried out to achieve the fine-grained level of digital education resources copyright protection.(3)Based on the existing copyright protection chain,this paper proposes a fine-grained digital education resources copyright protection chain——FCPChain.FCPChain is divided into three levels:interaction layer,service layer and data layer.Through decentralized blockchain service,fine-grained copyright information can be stored on the chain,stored on the Internet and stored on the Internet The collaborative supervision mechanism of multi scenario supported copyright transaction and traceability alliance chain under smart contract provides key technical support for fine-grained copyright protection architecture.(4)Develop and implement a fine-grained digital education resources copyright protection platform based on blockchain,including copyright authentication and storage,resource and copyright display,copyright trading module and alliance collaborative supervision and other functional modules.The results show that the proposed method has better effect.
