Securing Medical Data Records using Blockchain in a Cloud Computing Environment

In the current age of Information technology and Smart systems, where data is the new oil, it has become highly crucial to effectively store and share any sort of digital data. In recent years the high volumes of Medical Health Data have been under the data breaches by the third parties in the current centralized storage systems, raising concerns for patient data privacy and also the inconvenience for patients to access their own Health records. Blockchain technology with the integration of cloud storage for medical records provides enhanced security of data over the network through the immutable nature of blocks in blockchain and an effective decentralized storage system can be achieved by cloud computing. The model discussed in this paper gives the architecture and implementation of Medical Health Records systems secured through Blockchain and cloud technologies with various tools used. The working prototype which has been implemented is discussed with the demonstration of accessing and sharing of medical data by the patients with the doctors and insurance agencies. The proposed system meets the requirements of patient data privacy by giving greater control of medical data to patients.
