Protecting Privacy from Social Network Structure-based Inference

Technology Benefits

Currently, no social network services implement any privacy evaluation, alert, and recommendation techniques that could help end users easily evaluate and manage the level to which their private information is revealed. Neither does any personal software tool exist on the market that provides such functionality.
