Thus, in such an environment, privacy, confidentiality, and data consistency are the major challenges. Although cloud\u2010based EHR addresses the aforementioned discussions, these are prone to various malicious attacks, trust management and non\u2010repudiation among servers. Recently, due to the property of immutability, blockchain technology has been introduced to be as an auspicious solution for achieving EHR sharing with privacy and security preservation. Motivated by the above debates, we present BFHS, a blockchain\u2010based fine\u2010grained secure EHR sharing mechanism. On BFHS, we encrypt the EHR using ciphertext\u2010policy attribute\u2010based encryption (CP\u2010ABE) and upload it to the interplanetary file system (IPFS) for storage, while the matching index is encrypted via proxy re\u2010encryption and kept in a medical consortium blockchain. In addition, we created a credit assessment mechanism and incorporated it into the smart contract. Smart contracts, proxy re\u2010encryption, a credit evaluation mechanism, and IPFS all work together to give patients with a trustworthy EHR sharing environment and a dynamic access control interface. The thorough comparison and experimental analysis show that the proposed BFHS has more comprehensive security features and is more practicable.<\/jats:p>","DOI":"10.1002\/ett.4510","type":"journal-article","created":{"date-parts":[[2022,4,11]],"date-time":"2022-04-11T02:15:30Z","timestamp":1649643330000},"update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A fine\u2010grained and secure health data sharing scheme based on blockchain"],"prefix":"10.1002","volume":"33","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-2856-2561","authenticated-orcid":false,"given":"Jiahao","family":"Chen","sequence":"first","affiliation":[{"name":"College of Information and Engineering Yangzhou University Yangzhou China"}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-2045-0781","authenticated-orcid":false,"given":"Xinchun","family":"Yin","sequence":"additional","affiliation":[{"name":"College of Information and Engineering Yangzhou University Yangzhou China"},{"name":"College of Guangling Yangzhou University Yangzhou China"}]},{"ORCID":"http:\/\/orcid.org\/0000-0001-7165-398X","authenticated-orcid":false,"given":"Jianting","family":"Ning","sequence":"additional","affiliation":[{"name":"College of Computer and Cyberspace Security Fujian Normal University Fuzhou China"},{"name":"Institute of Information Engineering Chinese Academy of Sciences Beijing China"}]}],"member":"311","published-online":{"date-parts":[[2022,4,10]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrg3208"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.3414\/ME10-01-0038"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.3103\/S0147688211040083"},{"issue":"5","key":"e_1_2_10_5_1","first-page":"35","article-title":"Application of cloud computing technologies in information technology of hospitals","volume":"24","author":"Hou J","year":"2016","journal-title":"Electron Des Eng"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2018.2857205"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2016.12.027"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/2994581"},{"issue":"4","key":"e_1_2_10_9_1","first-page":"1","article-title":"Survey on blockchain technology and its application prospect","volume":"44","author":"He P","year":"2017","journal-title":"Comput Sci"},{"key":"e_1_2_10_10_1","doi-asserted-by":"crossref","unstructured":"VujicicD JagodicD RandicS et al.Blockchain technology bitcoin and ethereum: a brief overview.
