According to the World Health Organization\u2019s 2022 worldwide status report on road safety, there were 27,582 deaths linked to traffic-related events, including 4448 fatalities at the collision scenes. Drunk driving is one of the leading causes contributing to the rising count of deadly accidents. Current methods to assess driver alcohol consumption are vulnerable to network risks, such as data corruption, identity theft, and man-in-the-middle attacks. In addition, these systems are subject to security restrictions that have been largely overlooked in earlier research focused on driver information. This study intends to develop a platform that combines the Internet of Things (IoT) with blockchain technology in order to address these concerns and improve the security of user data. In this work, we present a device- and blockchain-based dashboard solution for a centralized police monitoring account. The equipment is responsible for determining the driver\u2019s impairment level by monitoring the driver\u2019s blood alcohol concentration (BAC) and the stability of the vehicle. At predetermined times, integrated blockchain transactions are executed, transmitting data straight to the central police account. This eliminates the need for a central server, ensuring the immutability of data and the existence of blockchain transactions that are independent of any central authority. Our system delivers scalability, compatibility, and faster execution times by adopting this approach. Through comparative research, we have identified a significant increase in the need for security measures in relevant scenarios, highlighting the importance of our suggested model.<\/jats:p>","DOI":"10.3390\/s23125388","type":"journal-article","created":{"date-parts":[[2023,6,8]],"date-time":"2023-06-08T02:02:28Z","timestamp":1686189748000},"page":"5388","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["DrunkChain: Blockchain-Based IoT System for Preventing Drunk Driving-Related Traffic Accidents"],"prefix":"10.3390","volume":"23","author":[{"given":"Hamza","family":"Farooq","sequence":"first","affiliation":[{"name":"Department of Computer Science, University of Engineering & Technology, (UET), Lahore 54890, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6446-4945","authenticated-orcid":false,"given":"Ayesha","family":"Altaf","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Engineering & Technology, (UET), Lahore 54890, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5536-8764","authenticated-orcid":false,"given":"Faiza","family":"Iqbal","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Engineering & Technology, (UET), Lahore 54890, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7156-9585","authenticated-orcid":false,"given":"Juan Castanedo","family":"Gal\u00e1n","sequence":"additional","affiliation":[{"name":"Higher Polytechnic School, Universidad Europea del Atl\u00e1ntico, Isabel Torres 21, 39011 Santander, Spain"},{"name":"Department of Projects, Universidade Internacional do Cuanza, Cuito EN250, Bi\u00e9, Angola"},{"name":"Research Group on Foods, Nutritional Biochemistry and Health, Fundaci\u00f3n Universitaria Internacional de Colombia, Bogot\u00e1 111311, Colombia"}]},{"given":"Daniel Gavilanes","family":"Aray","sequence":"additional","affiliation":[{"name":"Higher Polytechnic School, Universidad Europea del Atl\u00e1ntico, Isabel Torres 21, 39011 Santander, Spain"},{"name":"Universidad Internacional Iberoamericana Campeche, Campeche 24560, Mexico"},{"name":"Universidad Internacional Iberoamericana Arecibo, Puerto Rico, PR 00613, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8271-6496","authenticated-orcid":false,"given":"Imran","family":"Ashraf","sequence":"additional","affiliation":[{"name":"Department of Information and Communication Engineering, Yeungnam University, Gyeongsan 38541, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,7]]},"reference":[{"key":"ref_1","unstructured":"(2022, October 19).
