Applications of Blockchain Technology for Secure Transaction of Electronic Health Records

The healthcare industry is not immune to the trend of adopting new IT systems, and this includes hospitals and doctors’ offices. To store a patient’s medical history (including diagnoses and treatments), medical history (including diagnostic pictures), and financial data (including demographics and insurance details), a computerised database known as an “Electronic Health Record” (EHR) is used. Because medical records are typically private and must be shielded from prying eyes, ensuring their secure transfer is a top priority for healthcare systems. Electronic health records (EHRs) are used in the proposed study to ensure the security of all sent medical data, including the Chest X-ray MedPix images. This article describes a blockchain-based solution that patients can use to keep all their data in one secure location. This system was built with the Ganache tool on the Ethereum network, making use of Solidity and web3.js as well as other languages, tools, and approaches. In this study, a systematic method is described wherein blockchain smart contracts are used to record patient information and execute tasks in a distributed environment. After a smart contract has been deployed, all transactional communication occurs within its encrypted confines, protecting both the parties and their personal information. As an added bonus, the validated and broadcasted changes intended by the transaction can be checked. To ensure that government agencies have quick access to protected records, there is a cryptocurrency wallet (MetaMask) that stores the information in an encrypted, decentralised manner. Both patients and physicians can use the wallet to log in. In addition, the system will manage and protect all of the doctor and patient’s information. Things like the following are in scope for the proposed system: Users may now access the same information at the same time because to blockchain’s distributed ledger capabilities, which boosts productivity, establishes trust, and lowers barriers to entry. Setting individual permissions for users allows for safe data storage. In addition, the suggested method enables the safe transmission of patient medical records.
