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 Megías (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.
