A Dual-Chain Digital Copyright Registration and Transaction System Based on Blockchain Technology

Abstract

The increasing demand for digital copyright transactions in the big data era causes the emergence of piracy and infringement incidents. The traditional centralized digital copyright protection system based on centralized authority management of authoritative organizations has high registration cost. Blockchain, as a decentralized protocol, has the characteristics of decentralization, anonymity, auditability, security and persistency, which provide a solution to the current problems in the field of digital copyright. Combining with blockchain technology, this paper proposes a digital copyright registration and transaction system with double chain architecture. The blockchain based on digital copyright registration and management chain (RMC) and digital copyright transaction and subscription chain (TSC) can prevent information disclosure and improve the privacy protection by segregating account information and transaction information. Meanwhile, transforming the previous one-chain architecture into multiple chains in parallel on the RMC and TSC can reduce the redundant amount of computation, the consensus efficiency and improve the throughput rate. Experimental analysis shows that the system has the advantages of short registration time, high throughput and good scalability.
