MEDCHAIN FOR SAFEGUARDING PATIENT HEALTH RECORDS USING SMART CONTRACT AND WEB 3.0

Abstract

Health Insurance Portability and Accountability Act Regulations place a high priority on healthcare data security. In 2021, there were over 750 data breaches, and the top seven of those exposed over 193 million personal records to fraud and identity theft. Data security is the process of preventing data from being accessed by unauthorised parties and being corrupted at any point in its lifespan. Data across all apps and platforms is protected via data encryption, hashing, tokenization, and key management procedures. The security solution now in use data encryption software to successfully improve data security by converting plain text into encrypted cypher text using an algorithm (referred to as a cypher) and an encryption key. The encrypted data will be unintelligible to unauthorised individuals. With a permitted key, only that user can then decrypt the data. Yet, when data security becomes more lax, confidential data is lost because the key is so easily hackable due to the use of a single algorithm. This project offers a solution for this issue: an effective data security system that heavily relies on WEB 3.0 and smart contracts to protect data. Additionally, it offers total data protection, ensuring that a hacker is unable to alter the data in any way. The development of a framework known as WEB 3.0 includes a block chain framework to safeguard the data at the backend. Data access does not require an encryption or decryption key, thus there is no need to worry about data breaches or tampering by hackers. Thus, this system offers complete data protection for a hospital's medical records.
