Blockchain Applications for Secure Medical Data Sharing Using Smart Contract

Abstract

The healthcare sector is confronting a number of difficulties, including the vulnerability of sensitive patient data, privacy breaches, and medical record theft. Healthcare data is particularly sensitive and requires fail-safe measures to avoid unauthorized access, leakage, and modification. The existing environment is riddled with errors, interoperability challenges, complicated compliance laws, and poor data sharing procedures, all of which dramatically increase the danger of data theft. Recognizing the crucial need for revolutionary action, a paradigm change is advocated for healthcare data security. The suggested approach seeks not only to prevent fraud, but also to build a framework for assuring the absolute integrity and validity of shared patient data. This unique technology goes beyond security by providing the secure transmission of critical health information with access restricted to authorized persons. Adopting a blockchain architecture, like as Ethereum, creates a decentralized and tamper-resistant ledger that allows for the transparent and safe recording of patient-doctor interactions.
