The healthcare industry generates huge amounts of sensitive patient data every day, from medical histories to diagnostic images. Traditional systems for managing this data often prove vulnerable to breaches and are difficult to share between providers. Blockchain technology offers a solution through what are known as “distributed health records” (DHRs).
In a DHR, every patient information becomes a blockchain transaction. Patient’s private keys will give a right to open up his/her medical record or data; they become custodian of health care data, not an institution as it used to be in earlier times.
This is an extremely radical change: from institution-based control to patient-centered control over personal data.
