Development of an interoperable health data platform supported by Blockchain technologies
Alejandro Mateo Jiménez · 2019
This Master’s thesis proposes a decentralized solution based on blockchain to enable the exchange and use of the data obtained from all the devices associated with patients in a safe, fast and transparent way. Blockchain has two main issues to cope with in this kind of applications: privacy and performance. The performance is critical in IoT setting, where the number of events can be huge at specific moments. The technology to implement the blockchain should be capable to accomplish both the privacy requirements risen from the healthcare dimension and the performance requirements demanded from IoT solutions. Every interaction on patient data will be transparent, auditable and secure, and will be stored in the distributed ledger by means of a transaction. During this process, the privacy of the patient is permanently protected. The blockchain solution proposed in this project is built on the permission-based Hyperledger Fabric architecture that allows different levels of data access: users control who can see their records, how much they see and for how long.
