Healthcare idea

Hi guys,

I had an idea a while ago, don't know if its posted here or elsewhere. I also pitched in it /r/ethereum, but I don't think it's possible on that blockchain. Here goes:

For a health Hackathon ( I want to propose a situation where the patient's personal data is not stored in a hospital, but on a decentralized blockchain.

The whole reason to put that (personal confidential) data on a blockchain is for privacy and security reasons. So, I want to build a proof of concept with a team of programmers, doctors and patients to achieve this.

The data on the blockchain should be encrypted and not visible to anyone who does not have authorization, which is given by the owner of that data. The owner (patient) can authorize individuals like doctors, hospitals etc in a easy way, via nfc, qr code scanning and so on.

There are a lot of obstacles, like for instance:

  • list text here- what if the patient loses his/her private key
  • if the patient has an appointment with the specialist, how long will the data be usable/visible
  • legal issues of course

I want to know if this is possible..or am I just thinking stupid?

Thanks for your help!

This idea is being tried by a company called Patientory

Thanks for your help. I contacted Philips a while ago asking for their help in return of some credit. Fairly quick I got a reply saying they could not help me. They like the initiative though.

I would argue that storing data on a blockchain doesn't really gain privacy or security - it provides redundancy. Its like the worlds largest RAID 1 (mirror) array. I.e., if your data is on a well maintained blockchain (i.e., lots of users - nodes - and strong hashrate), then the data will be forever protected from modification or destruction. Those, however, can be useful properties for health data.

Additionally, how much data would you store in the blockchain? While Monero has the advantage of an adaptive blocksize, I don't know how much more information you can cram into each transaction. Indeed, it might cost 100's, if not thousands of USD worth of Monero to store a large amount of data on the chain.

Finally, I'm not sure how much of Monero's user-modifiable data fields are actually encrypted by the protocol. Everything transaction-centric is encrypted (addresses = stealthed, inputs - ring signature), but the payment ID is completely clear text (well, the old style), and there's some "transaction extra" field that I don't know much about.

Ultimately, I think this is a great application for what are known as "daughter chains". - secondary distributed database chains that hook back into the main chain to provide authentication of data, but exist separate from the main chain in order to reduce blockchain bloat.

But at the end of the day, you can do whatever you want with the blockchain. Its up to the miners to decide what goes in the blocks, and if you pack enough of a fee, anything will get in.

To tell you the truth Monero is a much better cryptocurrency then Ethereum. Ethereum lacks the monero anonymous-ness!!

Grand idea, but hard to implement i'd imagine
