Towards Privacy-aware Mobile Crowdsensing
Abstract: Mobile crowdsensing is an emerging sensing paradigm that outsources the collection of data to a crowd of participating sensing users with mobile devices. Nowadays, mobile devices are equipped with a plethora of on-board sensors (e.g., compass, accelerometer, gyroscope, camera, GPS) to sense various types of data from the surrounding environment. However, the wide adoption of mobile crowd sensing is largely hindered by its privacy concerns. Specifically, to facilitate the functionality at each stage of mobile crowdsensing, including sensing task allocation, sensing data collection, and result aggregation, sensing users report to the server with their location information, sensing capabilities, task preferences, and sensing results that will potentially disclose their daily routines, behavior patterns, and even real identities. This talk will discuss challenges of privacy leakages in current mobile crowdsensing systems, with focus on privacy-aware and secure data aggregation over incomplete crowdsensing data and location privacy preservation for crowdsensing tasks.
