Blockchain-based framework for secure and efficient exchange of electronic medical records on mobile cloud environments

Abstract

The maintenance of Electronic Medical Records (EMRs) on mobile cloud platforms, in which mobile devices are incorporated with cloud computing to ease healthcare information exchange between healthcare providers and patients, has become a paradigm shift in latest days. This cutting-edge strategy makes it possible to provide medical care at a low overhead expense, with a high level of flexibility, and with electronic health record access. Furthermore, this new approach also expresses concern over the confidentiality of patient data and the safety of the networks that support e-health systems. It is a tough problem to figure out a way to effectively share EMRs amongst mobile users while also maintaining maximum security measures in mobile cloud environments. In this research, a novel framework is presented for the sharing of EMRs that integrates blockchain technology and the decentralized Interplanetary File System (DIFS) on a mobile cloud. The empirical results suggest that the concept offers a useful method for ensuring the reliability of data transfers on mobile clouds, while also preserving important patient data from any potential dangers that may arise. Comparing the results of this performance assessment and security analysis to those of previously implemented data sharing models reveals significant performance enhancements in areas such as lightweight access control method, minimal network latency, maximum security levels, and data privacy protections.
