Integrating Blockchain in Healthcare to Secure Data

Abstract

Blockchain has become essential and is mostly used in the form of a distributed ledger in areas beyond the field of cryptocurrency like healthcare due to its distributed trust and allocated ledger design. A blockchain is made up of records arranged in a block structure in an ordered manner. It is virtually impossible to alter a block anywhere in the chain as all blocks after the changed block would have to be modified simultaneously. The fact that blockchain cryptographically verifies the transactions does away with the possibility of replay, man-in-the-middle attacks, and all other traditional “device-to-cloud” attacks. Healthcare data is often sensitive and private information such as billing, insurance, and prescription information, which requires a high level of security so that it is not manipulated in any way. With respect to the above context, our aim is to create a blockchain architecture for the field of healthcare to secure data.
