Dr. Yesha was the Founding Director of CARTA, one of the Industry\/University Cooperative Research Centers funded through a grant from the National Science Foundation (NSF).<\/p>\n<p>\u201cEarly on, the use of blockchain was mostly in the financial sector,\u201d said Dr. Yesha. \u201cNow, because of its low cost and high security, the use of blockchain for authentication is receiving rapidly growing interest in many fields. By applying blockchain to social media communications we hope to authenticate information that is critical to human welfare.\u201d<\/p>\n<p>Blockchain is a modern system for authenticating various types of transactions by comparing ledgers posted to a decentralized group of computers. Each transaction\u2014such as a social media post\u2014has a time stamp. With the use of a cryptographic encoding, time stamps, and data in a distributed network, any forgery of data can be quickly detected, according to Dr. Yesha.<\/p>\n<p>While many algorithms have been proposed for blockchain, the new initiative will use Chios, which offers fine-grained access control. Dr. Yesha\u2019s team will develop a computer program demonstrating how to capture fake news using Chios, and a set of experimental results to show the effectiveness of blockchain in tracking suspect posts.<\/p>\n<p>\u201cLeveraging cutting-edge, IDSC can be a leader in authenticating social media communications,\u201d said Dr. Yesha. \u201cAn effective blockchain tool can play a vital role in combating the spread of fake news.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Knight Foundation Chair of Data Science and AI, and IDSC Innovation Officer Yelena Yesha, PhD, is launching a collaborative blockchain project to detect and track fake news by identifying the source in real time. \u201cThe coronavirus pandemic has led to an explosion of misinformation, such as \u2018miracle cures\u2019, as well as scammers trying to take [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":395,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[147,53],"tags":[58,57,148,149,69],"_links":{"self":[{"href":"https:\/\/idsc.miami.edu\/magazine\/wp-json\/wp\/v2\/posts\/394"}],"collection":[{"href":"https:\/\/idsc.miami.edu\/magazine\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/idsc.miami.edu\/magazine\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/idsc.miami.edu\/magazine\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/idsc.miami.edu\/magazine\/wp-json\/wp\/v2\/comments?post=394"}],"version-history":[{"count":4,"href":"https:\/\/idsc.miami.edu\/magazine\/wp-json\/wp\/v2\/posts\/394\/revisions"}],"predecessor-version":[{"id":1177,"href":"https:\/\/idsc.miami.edu\/magazine\/wp-json\/wp\/v2\/posts\/394\/revisions\/1177"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/idsc.miami.edu\/magazine\/wp-json\/wp\/v2\/media\/395"}],"wp:attachment":[{"href":"https:\/\/idsc.miami.edu\/magazine\/wp-json\/wp\/v2\/media?parent=394"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/idsc.miami.edu\/magazine\/wp-json\/wp\/v2\/categories?post=394"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/idsc.miami.edu\/magazine\/wp-json\/wp\/v2\/tags?post=394"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
