Health data have tremendous value for organisations and criminals. The European Commission has classified health data as a unique resource owing to their ability to enable both retrospective and prospective research at a low cost. Similarly, the Organisation for Economic Co-operation and Development (OECD) encourages member nations to create and implement health data governance systems that protect individual privacy while allowing data sharing. This paper proposes adopting a blockchain framework to enable the transparent sharing of medical information among health entities in a secure environment. We develop a laboratory-based prototype using a design science research methodology (DSRM). This approach has its roots in the sciences of engineering and artificial intelligence, and its primary goal is to create relevant artefacts that add value to the fields in which they are used. We adopt a patient-centric approach, according to which a patient is the owner of their data and may allow hospitals and health professionals access to their data.<\/jats:p>","DOI":"10.3390\/healthcare11020170","type":"journal-article","created":{"date-parts":[[2023,1,6]],"date-time":"2023-01-06T01:48:19Z","timestamp":1672969699000},"page":"170","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Sharing Health Information Using a Blockchain"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7489-4380","authenticated-orcid":false,"given":"Luis B.","family":"Elvas","sequence":"first","affiliation":[{"name":"Information Sciences, Technologies and Architecture Research Center (ISTAR), Instituto Universit\u00e1rio de Lisboa (ISCTE-IUL), 1649-026 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4847-2432","authenticated-orcid":false,"given":"Carlos","family":"Serr\u00e3o","sequence":"additional","affiliation":[{"name":"Information Sciences, Technologies and Architecture Research Center (ISTAR), Instituto Universit\u00e1rio de Lisboa (ISCTE-IUL), 1649-026 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6662-0806","authenticated-orcid":false,"given":"Joao C.","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Information Sciences, Technologies and Architecture Research Center (ISTAR), Instituto Universit\u00e1rio de Lisboa (ISCTE-IUL), 1649-026 Lisbon, Portugal"},{"name":"Inov Inesc Inova\u00e7\u00e3o\u2014Instituto de Novas Tecnologias, 1000-029 Lisbon, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"94","DOI":"10.1016\/j.comnet.2017.10.002","article-title":"Potentials, trends, and prospects in edge technologies: Fog, cloudlet, mobile edge, and micro data centers","volume":"130","author":"Bilal","year":"2018","journal-title":"Comput.
