A Framework for Protecting Worker Location Privacy in Spatial Crowdsourcing
Summary: Privacy framework for workers in spatial crowdsourcing using differential privacy and geocasting. Outperforms privacy methods; jointly optimizes completion rate, travel distance, and overhead, with real data showing privacy at low performance cost. (summarized by gpt-5-nano on Feb 09 2026)
