SOUP: An Online Social Network by the People, for the People
Intervenant(s) : Xiaoming Fu (Univ. of Goettingen, Germany)
Concomitant with the tremendous growth of online social networking (OSN) platforms are increasing concerns from users about their privacy and the protection of their data. As user data management is usually centralized, OSN providers nowadays have the unprecedented privilege to access every user's private data, which makes large-scale privacy leakage at a single site possible. One way to address this issue is to decentralize user data management and replicate user data at individual end-user machines across the OSN. However, such an approach must address new challenges and recent works in this direction only show limited success. In this work we introduce a new, decentralized OSN called the Self-Organized Universe of People (SOUP). SOUP employs a scalable, robust and secure mirror selection design and can effectively distribute and manage encrypted user data replicas throughout the OSN. Extensive evaluations by simulation and a real-world deployment show that SOUP solves the key challenges decentralized OSNs currently face. This is joint work with David Koll (Univ Göttingen) and Jun Li (Univ Oregon).
