Anonymizing geo-social network datasets

Amirreza Masoumzadeh, James Joshi
2011 Proceedings of the 4th ACM SIGSPATIAL International Workshop on Security and Privacy in GIS and LBS - SPRINGL '11  
In this paper, we study the problem of anonymizing a geo-social network dataset, based on adversarial knowledge on location information of its users.  ...  Geo-social networking systems, such as Foursquare and Facebook Places, where users perform interactions based on their self-reported locations are growing fast nowadays.  ...  We formally define a geo-social network as follows. In the above definition, we consider the location domain to be abstract.  ...

Location-Related Privacy in Geo-Social Networks

Carmen Ruiz Vicente, Dario Freni, Claudio Bettini, Christian S. Jensen
2011 IEEE Internet Computing  
Geo-Social Networks (GeoSNs) extend social networks by providing context-aware services that support the association of location with users and content.  ...  We call such services Geo Social Networks (GeoSNs): they combine real-time location capabilities with traditional social network functionality.  ...  Check-In Based GeoSNs Check-in based social networks allow users to announce their presence in a particular place, such as a bar, a shop, or a park.  ...
