Almost one year ago, documents leaked by Edward Snowden revealed the existence of PRISM, a top secret program that allows the NSA to access user data from major Silicon Valley companies like Google, Facebook, Microsoft, Yahoo, an Apple.
The tech world was surprised and appalled — how could the companies allow something like that? As it turned out, they were just complying with the law. But PRISM was just the first of an array of revelations that uncovered how the NSA exploits technology, and our reliance on Silicon Valley companies, to conduct its surveillance.
On Tuesday, PBS Frontline released the second part of its documentary on the NSA revelations, The United States of Secrets, which tells the story of the tech companies' role in the NSA's surveillance programs.
Joins us at 2 p.m. ET for a live chat moderated by reporter Lorenzo Franceschi-Bicchierai, featuring PBS producer Martin Smith and security and privacy researcher Ashkan Soltani, who has also worked with The Washington Post on a series of reports on the Snowden leaks.
