Blockchain for transparent, privacy preserved, and secure health data management

Healthcare has become one of the most critical issues in human life. Most of society became elder, and they need to streamline monitoring and treatment to improve life quality and decrease potential risks. Using IoT technology for patient monitoring and health data gathering has increased dramatically. However, as we know, medical data that is usually formatted in electronic medical records contains sensitive data and should be protected from unauthorized access, tampering, and collusion. Using traditional methods like k-anonymity and l-diversity to preserve privacy does not apply to healthcare data because of intrinsic properties of Medicare data, such as volume, variety, and velocity. To share healthcare data between patients, doctors, and health keepers, healthcare systems are motivated to provide reliable, immutable, and confidential structures build on Blockchain. Using this technology, we can provide anonymity and transparency in the storage and sharing of healthcare data; at the same time, the accuracy of data remains intact.
