“…In many schemes [36,37,[40][41][42][43]49,50], multiple smart contracts are bundled together to create a blockchain-enabled dApp to automate the desired functionality between the copyright owner and the buyers. These contracts include a series of functions, such as data processing, value transfer, copyright protection, content distribution, and traceability.…”

“…The majority of the schemes guarantee content protection by using digital watermarking either as a standalone mechanism [44][45][46][47] or in combination with DRM [40,42,48,49] or encryption [37]. Only three schemes [50][51][52][53] used digital fingerprinting to provide copyright protection, while only two schemes, proposed in [39,41], used DRM techniques to ensure conditional access.…”

In this paper, we provide a holistic survey of multimedia content protection applications in which blockchain technology is being used. A taxonomy is developed to classify these applications with reference to the technical aspects of blockchain technology, content protection techniques, namely, encryption, digital rights management, digital watermarking and fingerprinting (or transaction tracking), and performance criteria. The study of the literature reveals that there is currently no complete and systematic taxonomy dedicated to blockchain-based copyright protection applications. Moreover, the number of successfully developed blockchain-based content protection systems is very low. This points towards a research gap. To fill this gap, we propose a taxonomy that integrates technical aspects and application knowledge and can guide the researchers towards the development of blockchain-based multimedia copyright protection systems. Furthermore, the paper discusses some technical challenges and outlines future research directions.
