Blockchain-based solutions for medical data sharing and patient privacy protection in India

The growing digitization of healthcare in India has led to an urgent need for secure, transparent, and patient-centric data management systems. Traditional centralized databases are vulnerable to breaches and unauthorized access, posing serious risks to patient privacy. This study explores blockchain-based solutions for secure medical data sharing and privacy protection within India’s healthcare ecosystem. Blockchain’s decentralized and immutable structure ensures data integrity, transparency, and confidentiality while enabling patient-controlled access through smart contracts. By integrating blockchain with initiatives such as the National Digital Health Mission (NDHM), healthcare institutions can achieve interoperability and secure exchange of electronic health records (EHRs). The proposed approach enhances trust, reduces data misuse, and strengthens the foundation for a secure digital healthcare infrastructure in India.
