Project Overview

The objective of this project is to develop a comprehensive and compelling framework, Social Network Guard, that satisfies diverse privacy properties, access control issues, identity management requirements, and usage patterns. The products resulting from this are three frameworks with demonstrative applications facilitating user-centered privacy management, content management and risk-aware access control.

The resulting applications in SNGuard are MController, Retinue, and Sigma. MController is a voting-based approach to sharing, Retinue is a risk-based approach to sharing, and Sigma is a circle-based approach to sharing based on Google+ circles.
