Abstract
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.

Summary
Content distribution is a process of digital distribution or delivery of multimedia content such as audio, text, animation and video. Multimedia content was distributed through physical exchange of papers, compact discs, or DVDs. With the technological evolution and growth of the Internet, multimedia content in the form of digital formats can be published online through digital distribution channels, such as the Internet-based delivery platforms [1] or peer-to-peer (P2P) file distribution and sharing systems [2], among others. With the technological evolution and growth of the Internet, multimedia content in the form of digital formats can be published online through digital distribution channels, such as the Internet-based delivery platforms [1] or peer-to-peer (P2P) file distribution and sharing systems [2], among others These online distribution platforms have become the de facto standards for content delivery ensuring great performance, wide availability, and cost efficiency. With the widespread use of these delivery platforms, the safety of the multimedia content, the preservation of copyright, the traceability of copyright violators, and the secure distribution of content have become increasingly ubiquitous problems for content owners, multimedia producers and distributors
