Abstract
We have created a solution called PMI-Chain to address the challenges faced by Electronic Medical Records (EMR) management systems. These challenges include data security, patient privacy, and access regulation, which are becoming increasingly complex. PMI-Chain is a blockchain-based system that aims to tackle these issues. Traditional EMR systems rely on centralized medical data storage, exposing them to risks such as cyberattacks and data breaches and reducing patient autonomy over their medical records. PMI-Chain is a secure and confidential data-sharing platform for patients, medical institutions, and insurance companies. It uses token-based smart contracts and dual ElGamal homomorphic encryption to protect vast amounts of medical data while allowing for reliable sharing among institutions. Patients have control over their encrypted medical records, and an advanced encryption scheme keeps their information private during insurance claim processing. PMI-Chain has undergone security analysis and testing, showcasing its robust security features and exceptional stability. Additionally, compared to other available solutions, it boasts a 44% and 67% reduction in encryption and decryption time overhead.
