An open framework for flexible plug-in privacy mechanisms in crowdsensing applications

摘要: Preserving user privacy is crucial for the wide adoption of crowdsensing and participatory sensing applications that rely on personal devices. Currently, each application comes with its own hardwired possibly undocumented support (if any), while horizontal protection mechanisms provided by operating runtime systems operate at a low level can significantly harm utility, or even render an useless. To achieve greater flexibility, we propose framework decouples mechanism from logic so it be developed another, perhaps more trusted party, which allows dynamic binding different to same running user's mobile device. We describe proof-of-concept implementation proposed Android, where are independently as separate plug-in components. Based simple but powerful API, possible implement range standard approaches, including collaborative schemes involve data exchanges among multiple
