The future of digital communication and privacy | Will Cathcart

People send 100 billion WhatsApp messages every day -- and they're all encrypted to protect them from potentially curious entities like companies, governments and even WhatsApp itself. With our increased reliance on digital communication tools during the COVID-19 pandemic, our fundamental right to privacy is more important than ever, says Will Cathcart, head of WhatsApp. He describes the tech and protocols the company built to prevent encryption services from being misused to spread disinformation or commit crimes -- while still safeguarding privacy. (This virtual conversation, hosted by head of TED Chris Anderson, was recorded June 16, 2020.)
