The management of Electronic Health Records (EHRs) has been completely transformed by the emergence of mobile and cloud computing, which has improved healthcare's accessibility, affordability, and flexibility. Sensitive medical data security in mobile cloud systems is still difficult to achieve, nevertheless. The InterPlanetary File System (IPFS) and blockchain technologies are integrated into mobile cloud services in this paper's proposed secure EHR exchange paradigm. Its smart contract-powered access control mechanism, which guarantees safe and regulated EHR sharing between patients and healthcare providers, is a crucial component. Amazon's cloud platform is used to deliver the framework's prototype, which is based on the Ethereum blockchain, via a mobile application. Its efficacy in protecting health information while facilitating effective communication is validated by empirical assessments. Furthermore, the lightweight access control paradigm improves security and privacy by lowering network latency. For safe EHR sharing in mobile cloud-based healthcare systems, this framework provides an effective and scalable solution.
