You can easily see the use case being a blockchain solution.
Challenges remain:-
- Infrastructure critical mass required
- Governance- bridging the gap between de-centralised and ungoverned
- Energy consumption- Proof of Work model energy intensive & not sustainable
- Legal- smart contracts rely on a yes/no model- no idea of compromise
But looking at the breaches outlined below the impetus should be to address the challenges
Yes, giving consumers control of their own medical data would revolutionize who owns medical data and how it is used. Concerns about researchers losing access to this amassed data are overstated. Patients have shown an overwhelming willingness to share their information for altruistic reasons (which far exceeds the track record of doctors and health systems when it comes to sharing data). The private and academic sectors are hard at work on a technology solution: one that is tamper-proof, ensures confidentiality and makes sharing medical data easy. One approach, known as a blockchain, is an encrypted data platform that would give patients digital wallets containing all their medical data, continually updated, that they can share at will.
