Title: Security and Privacy in Online Social Networks

Abstract:

Facebook has more monthly active users than almost any nation in the world. Whether one 
likes it or not, these users spend about 30 minutes daily browsing, posting, messaging, 
and otherwise socializing with others via OSNs and other social media. It's not surprising 
that social media has been taken to use by a wide range of individuals and organizations, 
from US President Obama who raised $690M in his reelection campaign of 2012, to the 
activists of Arab Spring in 2011, to numerous (legitimate and no so) organizations 
promoting their products and services, to law enforcement agencies. With so many different 
stakeholders, security and privacy in OSNs became an important, intriguing, and 
controversial subject. This talk will overview current research in OSN security and 
privacy, in a language accessible to wide audience, and elaborate on the detection of fake 
and compromised accounts in ONSs.
