It has also been suggested for application in the internet of vehicles (IoV) ecosystem as a way to improve service availability and reliability. Blockchain offers decentralized, distributed and tamper-proof solutions that bring innovation to data sharing and management, but do not themselves protect privacy and data confidentiality. Therefore, solutions using blockchain technology must take user privacy concerns into account. This article reviews the proposed solutions that use blockchain technology to provide different vehicle services while overcoming the privacy leakage problem which inherently exists in blockchain and vehicle services. We analyze the key features and attributes of prior schemes and identify their contributions to provide a comprehensive and critical overview. In addition, we highlight prospective future research topics and present research problems.<\/jats:p>","DOI":"10.3390\/jsan11040086","type":"journal-article","created":{"date-parts":[[2022,12,19]],"date-time":"2022-12-19T09:05:09Z","timestamp":1671440709000},"page":"86","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["A Review of Research on Privacy Protection of Internet of Vehicles Based on Blockchain"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8636-4558","authenticated-orcid":false,"given":"Wendong","family":"Chen","sequence":"first","affiliation":[{"name":"School of Computer Science and Communication Engineering, Jiangsu University, Zhenjiang 212013, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2942-6975","authenticated-orcid":false,"given":"Haiqin","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Software Engineering, East China Normal University, Shanghai 200062, China"}]},{"given":"Xiao","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Informatics, University of Edinburgh, Edinburgh EH8 9AB, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3124-5452","authenticated-orcid":false,"given":"Jinfu","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Computer Science and Communication Engineering, Jiangsu University, Zhenjiang 212013, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"217","DOI":"10.1007\/s11235-010-9400-5","article-title":"Vehicular ad hoc networks (VANETS): Status, results, and challenges","volume":"50","author":"Zeadally","year":"2012","journal-title":"Telecommun.
