We continue our Re-engineering Tokenization series this week by welcoming Phil Zimmermann, Creator of Pretty Good Privacy (PGP), into the SmarterMarkets™ studio. David Greely sits down with Phil to discuss his work in cryptography and its role in establishing trust and preserving privacy online. Phil shares his thoughts on what we need to be doing to make sure our technology is helping – not hindering – us in building the type of society we want to live in.
