John Podesta is no stranger to privacy issues. I can remember some interactions with him in the context of the Electronic Privacy Information Center (EPIC) during the Clinton Presidency. He has now been tasked with producing a big data-privacy report in 90 days. We are undergoing a revolution in the way that information about our purchases, our conversations, our social networks, our movements, and even our physical identities are collected, stored, analyzed and used. The immense volume, diversity and potential value of data will have profound implications for privacy, the economy, and public policy.
