Today, the field of copyright management faces several security vulnerabilities, making it a target for various types of rights violations, including piracy and unauthorized use of creative works. In this context, blockchain technology has emerged as a robust solution in this sector as it offers enhanced security, trust for creators, and increased transparency. In this paper, we first present an overview of the four main applications in the field of copyright management: (1) management of licenses and royalties, (2) market for artworks, (3) registration and protection of works, and (4) proof of anteriority. We then analyze in details the critical security vulnerabilities of these applications. Subsequently, we explain how blockchain technology can be used to mitigate these vulnerabilities. Finally, we discuss possible methods of preventing common blockchain-based attacks in these copyright management applications.
