One of the highlights of this year’s South by Southwest (SxSW) Interactive festival was a talk given by Phil Zimmermann about the current frontiers of identity theft and internet privacy. Personally it was amazing to get to hear Zimmermann speak in person. For those who are not familiar with him, Phil Zimmerman was one of the first famous online freedom fighters. He became the subject of much media attention in the early 90’s when he released PGP (Pretty Good Privacy), the first freely available military-grade email encryption program.
