Host

Abstract:
I will start the talk with our recent work on collecting and analyzing data from WhatsApp. I’ll summarize work on how WhatsApp is used by political parties in India to spread misinformation and hate speech. Next, I will delve deep into developing solutions for content moderation on WhatsApp, which is non trivial due to the end to end encrypted nature of WhatsApp. I will present two solutions: One based on an on-device setup to content moderation, before the content is encrypted, and the second based on a crowdsourced, bottom up model for fact checking. I will end with a discussion on potential future research directions in this space.
