Geo-social Networks (GeoSN) are characterized by the association of a spatio-temporal context to events, resources, and participants in a social network. They are rapidly attracting millions of mobile device users finding new useful location based services and a new way of socializing. This talk will briefly discuss new types of privacy threats generated from users implicitly or explicitly sharing the whereabouts of other users. Future challenges will be highlighted by the presentation of preliminary solutions for two different problems: privacy-aware posting of geo-tagged resources, and private proximity sharing.
