Blockchain-based security & privacy for biomedical and healthcare information exchange systems

Blockchain has become one of the most developing technologies in our country. Blockchain technology is a
decentralized, distributed ledger that records the sources of digital assets. Electronic Medical Record (EMR)
accommodates patient’s medical history, which has been carried out by a Physician or Doctor in a particular clinic or hospital or Healthcare center. Whereas, Electronic Health Record (EHR) holds patient’s entire health history, including immunization plans, diagnosis, lab reports, inoculation schedule, etc.,. This feature empowers the usage of Health IT in
a more secure way with the amendment of blockchain technology. These records are maintained smart contract
between the patient and the healthcare sector. In both EMR and EHR, the patient is the owner of his own data. This
paper incorporates the features of blockchain technology to provide a collaborative work on Electronic Medical
Records (EMRs) and Electronic Health Records (EHRs) and it concentrates highly in diabetes as it has a sharp
magnification in current world. Though it is tedious to implement this EHR all over the country, this paper works for its
implementation especially in the domain of diabetes.
Introduction
The significance of using EMR and EHR in today’s health care system is to provide ownership to every patient fo
