Unfortunately, this wealth of social information is fragmented across many different proprietary applications. Combined, it could provide a more accurate representation of the social world, and it could enable a whole new set of socially-aware applications. We introduce Prometheus, a peer-to-peer service that collects and manages social information from multiple sources and implements a set of social inference functions while enforcing user-defined access control policies. Prometheus is socially-aware: it allows users to select peers that manage their social information based on social trust and exploits naturally-formed social groups for improved performance. We tested our Prometheus prototype on PlanetLab and built a mobile social application to test the performance of its social inference functions under real-time constraints. We showed that the social-based mapping of users onto peers improves the service response time and high service availability is achieved with low overhead. %G English %2 https://inria.hal.science/hal-01055282/document %2 https://inria.hal.science/hal-01055282/file/Middleware2010_CameraReady_Prometheus.pdf %L hal-01055282 %U https://inria.hal.science/hal-01055282 %~ IFIP-LNCS %~ IFIP %~ IFIP-LNCS-6452 %~ IFIP-MIDDLEWARE %~ IFIP-2010
