Block chain Based - Smart Healthcare Record System

Blockchain technology is becoming increasingly important for improving the security of
private information, especially in industries like healthcare. It offers several key features
such as confidentiality, decentralization, security, and privacy—that help overcome some
of the common challenges faced by traditional healthcare systems. These challenges
include issues like phishing attacks, denial of service (DoS) attacks, and identity theft.
These security threats can compromise sensitive patient data, leading to serious
consequences. In response to these concerns, our project introduces a security solution
designed specifically for healthcare applications. The solution uses several advanced
technologies to address.A blockchain-based electronic health record (EHR) system has
been proposed to manage patient data and maintain computerized records across
different healthcare institutions. The main objective of this system is to provide immediate
access to patient health information while addressing concerns about privacy and security.
It is developed on the Ethereum network using programming languages, tools, and
technologies such as Ganache, Solidity, and web3.js. The system uses smart contracts to
provide security and privacy, and transactions are verified and propagated to the entire
decentralized network. The system includes a cryptocurrency wallet (MetaMask) with a
centralized privacy system that allows authorized parties to access and secure records
quickly. The proposed system aims to achieve several objectives such as allowing users
to receive the same data simultaneously, increasing efficiency, building trust, and reducing
barriers. It secures data storage by restricting user access and enables the secure transfer
of patient medical records. The solution allows for better transparency and ownership of
sensitive data, which can be recorded and safeguarded via blockchain technology,
therefore assisting the healthcare sector. This paper describes a medical record system
and a new protocol that can be used quickly and safely, paving the way for more secure
and efficient healthcare systems. Overall, the proposed system offers potential solutions to
the challenges
