  43. The Big Picture • Vulnerability: • Authenticity of online relationships + public information • Things to evaluate: • The attack in real-settings (Now, simulation-only). • Usability and expressiveness of privacy controls vs. privacy implications realized by users. • Identified issues: • How can social networking sites, or OSNs, distinguish between fake and real online identities (Social Sybil Nodes)? • Future work: • Social Collaborative Security (threat identification, opinion mining, reasoning, alert diffusion, etc.)
