How blockchain will kill fake news (and four other predictions for 2020) – Computer World

In August, the U.S. Defense Advanced Research Projects Agency (DARPA) began developing software that can discover fake news hidden among more than 500,000 stories, photos, video and audio clips. And in September, Facebook formed an industry group to develop deep fake video detection tools. Facebook’s Partnership on AI includes Microsoft Amazon, Google, DeepMind, and IBM, as well as academics from Oxford, MIT, Cornell Tech, UC Berkeley and other schools.

If successful, the efforts by DARPA, Facebook and others will “blacklist” fake content to block it from reaching target victims and create an algorithm that authenticates and tracks content movement to “whitelists,” ensuring its provenance.

“Blockchain technology is proven to excel at supporting this use case as it enables a ‘shared single version of truth’ across multiple entities based on immutable data and audit trails,” Litan wrote.
