Blockchain-based copyright protect – EurekAlert

Blockchain is a decentralized technology used to protect the security and privacy of online transactions and is usually associated with cryptocurrencies such as Bitcoin. However, it is a mechanism that can be applied to all kinds of digital exchanges. In a new study, researchers from the K-riptography and Information Security for Open Networks (KISON) group at the Internet Interdisciplinary Institute (IN3) Amna Qureshi and professor David MegĂ­as (who is also the director of the IN3) analysed existing blockchain-based multimedia content protection systems and established a taxonomy to classify them according to their technical features, the protection techniques they use and their performance. The study is the first detailed analysis of this type of application and looks at the technological and scientific challenges for their improvement and implementation.

The researchers said: “blockchain has an excellent potential to be broadly applied in copyright protection and management applications. However, there are still many open issues that need to be further researched and analysed in order to create workable copyright protection applications that can fully benefit from the use of the blockchain technology.”

A gap in the research

Because of the growth in the distribution of audiovisual content through online platforms and peer-to-peer (P2P) file sharing, matters such as content security, copyright protection and piracy tracing are increasingly more pressing for the owners, producers and distributors of content. The researchers said that, faced with these problems, blockchain makes it possible to “upload copyrighted content, control licensing/copyright options, manage distribution, trace sources of
