MediChain is a Medical Big-Data Platform. Our proposed system allows patients to store their own data off-chain in an appropriate geographic domain, and give access to doctors and specialists anywhere, regardless of the payer network or EMR used.
Patients, doctors, and hospitals could put data into a compliant cloud which becomes part of the MediChain ecosystem and the blockchain stores pointers and rules on usage and anonymity, while the data itself is stored off-chain in a compliant cloud.
Patients could access their data at any time and allow other doctors and hospitals to access selected parts of the data transcending individual electronic medical records systems.
Researchers and Pharmaceutical companies would access the data as big data in fully anonymised form. It is monetized by the ability to voluntarily give anonymised access to untampered data to pharmaceutical companies, researchers and insurers. Potentially it may also be used for prescription management.
Its unique architecture allows fast access and small downloads to make it practical for everyday medical use. The protocol is based on smart cards (optional), Homomorphic encrypted access rules tables, json data formats, lightweight and strong cryptography and blockchain technology, which brings enhanced transparency and reliability in medical data exchange at every level, from devices to EMR to unprecedented opportunities for privatised big data sharing.
