AnnounceAnnounce, will be available in the newly launched plugin Trusted NewsUsing blockchain technology to detect fake news. Currently, a beta version of the plug-in for Chrome has been launched. After adding the plug-in, users can see a small window of Trusted News, which marks the trustworthiness of the web page.
Trusted News technology for labeling sites comes from security firm MetaCert. MetaCert is positioned as a content classification platform. By analyzing the content, source and historical data of the webpage, it can rate the credibility of the webpage, so as to provide security protection for App or browser and filter out malicious links. This technology has been applied in many ways, such as the launch of the green version of the Chrome plug-in and the iPad web browser in 2012, providing Internet users with web pages free of malicious or pornographic content.
Beginning in 2017, MetaCert began to label fake news, and has accumulated a huge data set of news content so far. The addition of blockchain to Trusted News this time means that after MetaCert tags the website, it will build a database and move it to Ethereum to avoid artificial tampering of data and ensure that the tagging process is open and transparent. It is understood that after some fake news websites are marked, they will bribe the marked party to open a white list, and this problem can be avoided by going to the chain. At the same time, MetaCert will issue tokens on Ethereum to reward contributors who trace the source of information.
In the future, Trusted News is expected to join user evaluation mining and upload evaluation content to the chain. That is, people can mark and rate the website. If the rating is recognized by more people, it can be regarded as an honest vote in line with public opinion and will be rewarded with tokens. Otherwise, it will not be recognized by the system.
It is reported that Trusted News currently divides news into 8 dimensions: reliable, unknown (cannot be accurately assessed due to insufficient data), unreliable (false or misleading news), satirical (publishing satirical content), biased (political biased content, or an obvious point of view), vicious (the website contains malware such as phishing programs, viruses or spyware), ClickBait (headline party style), and user-generated content (contains content contributed by UGC in the form of tweets, blogs, etc.) .
In the effort to prevent the spread of fake news, in addition to the labeling scheme such as Trusted News, Google has tried to make structural changes to the search algorithm, prohibiting the use of Google advertising tools on fake news websites, Facebook crazily deleting posts, and attaching Trust index and other coping methods, which one can better prevent fake news?
