Privacy Preserving Publishing of Spatio-temporal Data Sets

Spatio-temporal datasets are becoming more and more popular due to the widespread usage of GPS enabled devices, wi-fi location technologies, and location based services that rely on them. However, location, as a highly sensitive data type also raises privacy concerns. This is due to the fact that our location can be used to infer a lot about us. Therefore special attention must be paid when publishing spatio-temporal data sets. In this seminar, I will first make a general introduction to privacy preserving data publishing and then talk about some research issues regarding privacy-preserving publishing of spatio-temporal data sets together with the proposed solutions.
