A Framework for Secure Healthcare System Using Blockchain and Smart Contracts

Abstract

The term “electronic healthcare” refers to patient records that are stored in digital format. Patient-centered data allows any authorized individual to view the data from any place and at any time. E-health insurance leads to more social and health benefits as well as fewer health mistakes. An electronic health record is a digital repository of a patient's personal history created by one or more care delivery organizations. The term blockchain was formed from the terms block and chain, as well as the list of transactions known as a block, which is associated with the cryptographic technology. Each block is linked to the block header that came before it. A blockchain only stores one patient's record. This article outlines a strategy for safeguarding healthcare data. The suggested model's key features are interoperability and safe storage and access to patient data.
