Role of Blockchain Technology in Data Security for Healthcare

Abstract

Considering growing demand of medical record management it has been considered that there is requirement to keep patient record and identity management in healthcare. To improve the safety and reliability of medical records, the blockchain technology has been determined to be an appropriate tool. The function of blockchain technology in healthcare data security is the focus of this study article. An example of a transaction in this system would be the recording and storage of a patient's medical history in a public ledger known as a block. Two parties are required for a transaction to take place. For every transaction to go through, the system needs the approval of the vast majority of users. Records of transactions kept on a blockchain are immutable and resistant to tampering. Researchers are now encrypting patient data before storing it on blockchain, which adds an extra degree of protection. Additionally, blockchain's security and speed have been enhanced by the use of advanced hashing mechanisms.
