Securing Medical Data using Block Chain Technology

Now a day’s encrypting sensitive information like medical data has been tough even though a lot of security is provided. In olden days hospitals were maintaining paper-based record and were updated every six months and patient view their record rarely. Recently health sector has been digitized and coming to the health sector each and every patient’s medical data has to be stored with high security and accessibility. Health care system uses digital methods to maintain Electronic Health Record (EHR). To overcome security issues in health records the proposed system introduces Block chain technology with hashing to secure the files stored on the cloud. From the Proposed work there is an opportunity to reduce the turnaround time for EHR sharingand improvedecision making for medical care, and reduce the overall cost. It provides a unique opportunity to develop a secure and trustable EHR data management and sharing system using Block chain.
