Blockchain-Based Digital Copyright Management Systems: Design, Implementation, and Evaluation

Abstract

The rise of digital content and the internet has made copyright protection and management increasingly challenging. Blockchain technology offers a promising solution for secure, transparent, and decentralized digital rights management (DRM). This paper presents a comprehensive study on the design, implementation, and evaluation of blockchain-based digital copyright management systems. We propose a novel architecture that leverages smart contracts and decentralized storage to enable efficient and tamper-proof registration, licensing, and distribution of digital content. The system is implemented on the Ethereum blockchain and evaluated through extensive experiments and case studies. The results demonstrate the effectiveness and practicality of our approach in terms of security, scalability, and usability. We also discuss the potential applications, challenges, and future directions of blockchain-based DRM. Our work contributes to the advancement of blockchain technology in the field of intellectual property protection and management.
