Decentralized Secure Personal Health Record Monitoring System using Blockchain

Design of security systems for Personal Health Record (PHR) continuous to remain an active research area. Machine Learning and Big data on health care are used for prediction of data or diseases. But there is no traditional system which id used to secure the data and provide emergency access in emergency conditions. PHR is a private and secure record of any individual through which an individual could access, manage and share his/her health data. In hospital management systems, there is an opportunity of sharing PHRs by the hospitals, doctors or workers for his/her private profit so there is no secure record management for restricting the unauthorized access to providing details in emergency circumstances for accessing his/her PHR. The major goal of this project is to provide security to clinical data by a secure record management ledger and provide different levels of abstraction with limited access permissions using some granular access rules on smart contracts on PHR using blockchain. For emergency access we gave some permissioned access rules to the PHR dependent on emergency PHR information that patient can control access for the record using grant and revoke permissions to any doctor. We analyse the proposed framework's overall performance using Hyperledger fabric which is permissioned block chain dependent on security, privacy and accessibility and response time.
