A Blockchain System for Fake News Detection

The media greatly impacts the world’s perception and what is happening in it. Nowadays, the Internet is a medium where information flowing from all over the world meets. Every year, more and more information websites are created from which we learn about the reality surrounding us. The problem is that many of these websites do not use primary and reliable sources but only use sources that have already been processed and duplicated. Very often, these portals omit not only important facts for a given event but also reproduce false information. There are also situations where fake news is deliberately created and disseminated. The phenomenon called “fake news” has long been known as disinformation or propaganda. Contemporary scientific analyses focus primarily on its new dimension, i.e. the dissemination of untrue or incorrect information on the Internet, the reasons for the popularity of fake news on the Internet, and the speed and manner of information dissemination. However, the most important problem is preventing the spread of fake news. In the article, the authors propose a method of authorising content using blockchain technology. The presented method is resistant to manipulation attempts, confirmed by the tests.
