The idea of smart connectivity also provides a new direction for Location-Based Social Networks (LBSNs). However, due to limited calculate ability and internal storage space of IoT devices, historical location data of users is generally stored in the central server, which is likely to cause the disclosure of users\u2019 private data. In this paper, we propose a Blockchain-enabled Privacy-Preserving Location Sharing (B-PPLS) scheme, which is a new framework that not only protects user location privacy but also provides effective location sharing services for users. For B-PPLS, location data owners can share the location area instead of location coordinates to Requesters, in order to realize the location privacy preserving. Also, the Merkle hash tree is utilized to divide the location area, so as to realize the multilevel privacy preserving. Furthermore, four algorithms are proposed to achieve the four stages of initialization, location record, location sharing, and location verification, respectively. Finally, we analyze the security of the proposed B-PPLS scheme and compare the performance with other related location privacy-preserving schemes by experimental evaluation.<\/jats:p>","DOI":"10.1155\/2021\/9997887","type":"journal-article","created":{"date-parts":[[2021,7,1]],"date-time":"2021-07-01T18:06:22Z","timestamp":1625162782000},"page":"1-15","source":"Crossref","is-referenced-by-count":4,"title":["Blockchain-Enabled Privacy-Preserving Location Sharing Scheme for LBSNs"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6766-4544","authenticated-orcid":true,"given":"Liang","family":"Zhu","sequence":"first","affiliation":[{"name":"School of Computer and Communication Engineering, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0917-3720","authenticated-orcid":true,"given":"Xiaowei","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Computer and Communication Engineering, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7318-4603","authenticated-orcid":true,"given":"Liping","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Computer and Communication Engineering, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zengyu","family":"Cai","sequence":"additional","affiliation":[{"name":"School of Computer and Communication Engineering, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianwei","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Computer and Communication Engineering, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2016.12.033"},{"issue":"5","key":"2","first-page":"959","article-title":"Toward pattern and preference-aware travel route recommendation over location-based social networks","volume":"35","author":"L.
