To encourage more people to participate in sensing tasks, various incentive mechanisms were proposed. However, participating in sensing tasks and getting rewards can inherently risk the users\u2019 privacy and discourage their participation. In particular, the rewarding process can expose the participants\u2019 sensor data and possibly link sensitive data to their identities. In this work, we propose a privacy-preserving reward system in crowdsensing using the blind signature. The proposed scheme protects the participants\u2019 privacy by decoupling contributions and rewarding claims. Our experiment results show that the proposed mechanism is feasible and efficient.<\/jats:p>","DOI":"10.3390\/s21217045","type":"journal-article","created":{"date-parts":[[2021,10,24]],"date-time":"2021-10-24T22:07:11Z","timestamp":1635113231000},"page":"7045","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["PARS: Privacy-Aware Reward System for Mobile Crowdsensing Systems"],"prefix":"10.3390","volume":"21","author":[{"given":"Zhong","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Computer Engineering, Myongji University, Yongin 17058, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dae Hyun","family":"Yum","sequence":"additional","affiliation":[{"name":"Department of Information and Communication Engineering, Myongji University, Yongin 17058, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minho","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, Myongji University, Yongin 17058, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2419","DOI":"10.1109\/COMST.2019.2914030","article-title":"A survey on mobile crowdsensing systems: Challenges, solutions, and opportunities","volume":"21","author":"Capponi","year":"2019","journal-title":"IEEE Commun.
