The digitization of health records has massively increased Health Information Exchange (HIE) activities among different practitioners, but it has lagged behind Electronic Health/Medical Records (EHRs/EMRs) adoption for numerous reasons, including confidentiality, interoperability, integrity, and privacy-related concerns.

Abstract
The digitization of health records has massively increased Health Information Exchange (HIE) activities among different practitioners, but it has lagged behind Electronic Health/Medical Records (EHRs/EMRs) adoption for numerous reasons, including confidentiality, interoperability, integrity, and privacy-related concerns. In this paper, we present a Blockchainas-a-Service based solution for HIE (BaaS-HIE). In particular, our design work involves the use of a private Blockchain and smart contracts as access control manager to medical records. In order to maintain high level of performance for applications, thus that such applications could be economically viable, all of the health data are encrypted and stored into a decentralised InterPlanetary File System (IPFS) and the hash of the assets URI is stored in blockchain. Our experimental results demonstrate the feasibility of the proposed approach in offering a decentralized and fine-grained accessibility mechanism for the patient and the doctor in a given healthcare system.Pubblicazioni consigliate
