These data serve as important information sources for many domains, including disaster management, biosurveillance, smart cities, and smart health, among others. However, this scenario involves the collection of personal data, raising new challenges related to data privacy protection. Therefore, we aim to provide state-of-the-art information regarding privacy issues in the context of IoT, with a particular focus on findings that utilize the Personal Data Store (PDS) as a viable solution for these concerns. To achieve this, we conduct a systematic mapping review to identify, evaluate, and interpret the relevant literature on privacy issues and PDS-based solutions in the IoT context. Our analysis is guided by three well-defined research questions, and we systematically selected 49 studies published until 2023 from an initial pool of 176 papers. We analyze and discuss the most common privacy issues highlighted by the authors and position the role of PDS technologies as a solution to privacy issues in the IoT context. As a result, our findings reveal that only a small number of works (approximately 20%) were dedicated to presenting solutions for privacy issues. Most works (almost 82%) were published between 2018 and 2023, demonstrating an increased interest in the theme in recent years. Additionally, only two works used PDS-based solutions to deal with privacy issues in the IoT context.<\/jats:p>","DOI":"10.3390\/s24072197","type":"journal-article","created":{"date-parts":[[2024,3,29]],"date-time":"2024-03-29T06:33:16Z","timestamp":1711693996000},"page":"2197","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["A Systematic Review on Privacy-Aware IoT Personal Data Stores"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6082-9211","authenticated-orcid":false,"given":"George P.","family":"Pinto","sequence":"first","affiliation":[{"name":"Institute of Computing, Federal University of Bahia, Canela 40170-110, Brazil"},{"name":"Federal Institute of Bahia, Santo Ant\u00f4nio de Jesus 44571-020, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8233-6071","authenticated-orcid":false,"given":"Praveen Kumar","family":"Donta","sequence":"additional","affiliation":[{"name":"Distributed Systems Group, TU Wien, 1040 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6872-8821","authenticated-orcid":false,"given":"Schahram","family":"Dustdar","sequence":"additional","affiliation":[{"name":"Distributed Systems Group, TU Wien, 1040 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0197-0909","authenticated-orcid":false,"given":"C\u00e1ssio","family":"Prazeres","sequence":"additional","affiliation":[{"name":"Institute of Computing, Federal University of Bahia, Canela 40170-110, Brazil"},{"name":"Distributed Systems Group, TU Wien, 1040 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"36","DOI":"10.1093\/idpl\/ipw026","article-title":"The business of personal data: Google, Facebook, and privacy issues in the EU and the USA","volume":"7","author":"Esteve","year":"2017","journal-title":"Int.
