No place to hide: a study of privacy concerns due to location sharing on geo-social networks
- Publisher: IARIA
User location data collected on Geo-Social Networking\ud applications (GeoSNs) can be used to enhance the services\ud provided by such applications. However, personal location information\ud can potentially be utilised for undesirable purposes\ud that can compromise users’ privacy. This paper presents a study\ud of privacy implications of location-based information provision\ud and collection on user awareness and behaviour when using\ud GeoSNs. The dimensions of the problem are analysed and\ud used to guide an analytical study of some representative data\ud sets from such applications. The results of the data analysis\ud demonstrate the extent of potential personal information that may\ud be derived from the location information. In addition, a survey is\ud undertaken to examine user awareness, concerns and subsequent\ud attitude and behaviour given knowledge of the possible derived\ud information. The results clearly demonstrate users’ needs for\ud improving their knowledge, access and visibility of their data sets\ud as well as for means to control and manage their location data.\ud Future work needs to investigate the current state of personal\ud data management on GeoSNs and how their interfaces may be\ud improved to satisfy the highlighted users’ needs and to protect\ud their privacy.
