HealthGuard: Blockchain-Powered Healthcare Data Security

Healthcare information is sensitive and private. Consequently, Users are liable for assuring the confidentiality of their medical records. It is simple to steal, or even eradicate medical data. In that cases the medical data may not be found the same as before. This affects the right treatment to the patient to save the patient’s life. Traditionally, the raw medical data of a patient was preserved in a database and could be hacked by hackers. Medical applications are particularly vulnerable to security concerns including data theft. The security problem in medical applications has been fixed by the Blockchain. Because of the unique features like decentralization, consistency, and cryptography the Blockchain technology is used for storing the medical data securely. It uses shared keys and the data is stored in the form of blocks based on the consensus procedures. The performance of various Blockchains are analyzed for secure medical data storage.
