A survey on privacy in mobile participatory sensing applications

摘要: Abstract: The presence of multimodal sensors on current mobile phones enables a broad range novel applications. Environmental and user-centric sensor data unprecedented quantity quality can be captured reported by possible user base billions phone subscribers worldwide. strong focus the collection detailed may however compromise privacy in various regards, e.g., tracking user's location. In this survey, we identify sensing modalities used participatory applications, assess threats to when personal information is sensed disclosed. We outline how aspects are addressed existing determine adequacy solutions under real-world conditions. Finally, present countermeasures from related research fields, discuss their applicability scenarios. Based our findings, open issues guarantee sensing.
