“Honey bots” that counter malicious bots. An app called Sanity Check. Cyber Security Bonds. And technology that breaks the grip of online echo chambers. Those are just some of the ideas that college students from around the country presented Thursday in Cambridge as part of the Defending Digital Democracy Project’s first-ever Information Operations Technical and Policy Hack-a-thon.

The Defending Digital Democracy Project wants your help in solving one of the biggest problems facing democracy and our society—information operations intended to influence domestic opinion, inflame divisions, or undermine trust in institutions. There has been a lot of discussion in the media, academia, and policy circles about the dangers of information operations—like spreading information through fake social media personas to further social divisions and influence public behavior. But we need more than talk to stop this—we need action. That is what this contest is all about.
