Then, the worker moves to the specified locations to perform the tasks. However, it usually demands workers to upload their location information to the spatial crowdsourcing server, which unavoidably attracts attention to the privacy-preserving of the workers\u2019 locations. In this article, we propose a novel framework that can protect the location privacy of the workers and the requesters when assigning tasks to workers. Our scheme is based on mathematical transformation to the location while providing privacy protection to workers and requesters. Moreover, to further preserve the relative location between workers, we generate a certain amount of noise to interfere the spatial crowdsourcing server. Experimental results on real-world data sets show the effectiveness and efficiency of our proposed framework. <\/jats:p>","DOI":"10.1177\/1550147719830568","type":"journal-article","created":{"date-parts":[[2019,3,13]],"date-time":"2019-03-13T12:03:56Z","timestamp":1552478636000},"page":"155014771983056","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Toward location privacy protection in Spatial crowdsourcing"],"prefix":"10.1177","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6646-1059","authenticated-orcid":false,"given":"Hang","family":"Ye","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology and Suzhou Institute for Advanced Study, University of Science and Technology of China, Hefei, P.R.
