Explore the critical issue of location privacy in mobile crowdsourcing applications through this 20-minute conference talk from USENIX Security '19. Delve into the challenges of implementing effective location privacy-preserving mechanisms (LPPMs) in mobile crowdsourcing (MCS) projects. Examine the performance of existing LPPMs on real-world data from two MCS projects, uncovering their limitations and impact on application utility. Understand the mismatch between current privacy solutions designed for location-based services and the unique requirements of MCS applications. Gain insights into potential research directions for developing new location privacy solutions tailored to MCS needs, addressing the growing privacy concerns in an increasing number of such applications.
