Blockchain in Healthcare - Efficiently Storing and Sharing Patient Health Data

The sharing of personal health records can be beneficial to diagnosis and medical research. Currently most of the health record schemes are fully dependent on third-party cloud service providers, which is not secure enough because there is a high risk of leaking confidential health data. Blockchain provides a better solution for storing and sharing data because of its decentralized and tamper-proof features. We proposed a new Blockchain-based personal healthcare data storage and sharing scheme. We used highly secure and efficient encryption-decryption mechanisms along with blockchain to tackle the risk of privacy disclosure.
