Traditionally and as of today, patient’s health information is stored on organization owned centralized database. The current system seems fine at first but has some serious underlying issues. Some of the issues are that the system is not patient centric, seamless data sharing is not possible, inconvenient for patient, etc. To summarize, the one who stores the data owns the data. So, it is evident that there is a need for a system which is more patient oriented. Such system can be developed by using blockchain. Since the nature of blockchain is decentralized, EHRs when stored on a blockchain will take the ownership of data away from the hospitals and will put patients in control of the data. Ethereum based decentralized application can be developed to store patient’s confidential medical information in a distributed way. The application will store patient’s data in an encrypted format to provide additional layer of security and will also overcome the drawbacks of public blockchain.
