Abstract: With the rapid proliferation of mobile devices equipped with rich on-board sensors (e.g., camera, accelerometer, compass, etc.), crowdsensing emerges as a new sensing paradigm, which outsources sensing tasks to a crowd of ubiquitous participants. The Sybil attack is a harmful threat to crowdsensing, in which a malicious user illegally forges multiple identities to participate in the system. It can allow a rapacious user to receive more rewards without contributing extra efforts. In addition, it can even enable a malicious party to control the crowdsensing results. This talk will present how to defend against Sybil attacks in crowdsensing using a combination of economic and systematic approaches.
