Patientory will store patient health records on a decentralized platform.

So no patient privacy ?
No medicinal secret ?

it will be secure and private because healthcare law requires it.

How it could be private as the blockchain is public ?

That's actually possible, like with Monero and Zcash. You could also hold hashes on the blockchain. But imo the idea itself won't work

Okay, but if the data are hidden, how the hospital itself will recover them ? With a key ?
Yes, it won't work, or I need some better infos
