The primary benefit of blockchain in the healthcare industry for patients is total control over personal
health records. Blockchain enables secure, decentralized storage of health data, allowing patients to
control access to their information and share it with healthcare providers as needed.
Key Details:
Data Ownership and Privacy: Blockchain gives patients the ability to own and manage their health
records. They can grant or revoke access to different healthcare providers, ensuring that only
authorized personnel have access to their data.
Improved Security: Health records stored on a blockchain are encrypted and decentralized, making
them resistant to tampering and unauthorized access. This enhances patient privacy and reduces the
risk of data breaches.
Interoperability and Accessibility: Blockchain facilitates seamless sharing of health records across
different healthcare providers and systems, improving coordination and care continuity without
compromising data integrity.
Therefore, B. Total control over personal health records is the correct answer, as it represents a
significant advantage for patients in managing their healthcare information securely.
