In the last few years, a number of research and development projects have worked on creating safe and reliable systems for the healthcare industry using pervasive and mobile healthcare (mHealth) solutions. Most modern mHealth solutions use centralized storage, like cloud computing servers. This can make maintenance more expensive, require more storage space, and put the health-critical data that is created, used, and sent over ad hoc networks at risk of privacy and security breaches. To overcome these limitations, we conducted this study with the aim of integrating mobile computing (devices that process health-critical data) and blockchain technology (an infrastructure for secure storage and retrieval of health-critical data), concentrating on data security and privacy through the implementation of a blockchain mHealth system. We used an incremental approach by (i) creating a framework that can be used as a guide for designing mHealth systems that use blockchain, (ii) writing a set of algorithms as a proof-of-concept to automate the framework, and (iii) testing each part to make sure that our proposed framework is scalable, efficient in terms of computation and energy use. The proposed framework has been implemented as a front end, using a mobile app interface that uses some of the back-end features of the Inter Planetary File System (IPFS) and the Ethereum blockchain to safely manage m health data. We will use a case-study approach to show how health units, doctors, and patients can all safely get to and share health-critical information. We created a smart contract prototype and put it on the Ethereum TESTNET network in a Windows environment to test the framework. The evaluation results show that the system is (a) scalable because it can handle a lot of queries at once (10–41ms), (b) computationally efficient because it uses very little CPU (1.5%–2.5%), and (c) energy efficient because it only uses 40,000 units of gas for every 1,000 bytes of data. The suggested solution, which includes the framework, algorithms, and experimental evaluation, is meant to help people architect and implement state-of-the-art cybersecurity mHealth solutions based on blockchain technology.
