The document summarizes Session 4 of the Global Forum 2012 in Stockholm which focused on new usages of privacy and security on Facebook. Key points include: 1) Facebook's mission is to make the world more open and connected and it now has over 1 billion monthly active users across all platforms and 600 million on mobile alone. 2) Facebook has shifted from a "real name" culture to one that values transparency, control, and accountability regarding user privacy and data use. 3) Facebook employs several security measures to protect user accounts including double authentication, login notifications, encrypted connections, remote logout capabilities, one-time passwords, and social authentication.
