For those of you who haven't kept up, the National Security Agency (NSA's) Prism program has been in the news. Prism provides the NSA with access to data on the servers of Microsoft, Google, Facebook, etc, extracting audio and video chats, photographs, e-mails, documents, etc.
Prism is just a part of the NSA's larger mass electronic surveillance program that covers every possible path someone might use to communicate; tapping raw data as it flows through fiber optic cables and Internet peering points, copying the addressees on all letters you physically mail, all credit card purchases, your phone calls and your location (courtesy your smart phone). - Steve Blank
