Blockchain based hospital data management using Hyperledger Fabric.

Technological progress has pushed blockchain technology to cover a multitude of use cases and environments with different types of technology and frameworks. HyperLedger Fabric is a framework for creating a permissioned blockchain. Blockchain is defined as a decentralized, distributed and immutable ledger. Permissioned indicates that all nodes and users need permission to take part in the network, meaning it is within a controlled and centralized environment. We propose HyperLedger Fabric for use in a hospital as a data storage. Security and reliability are vital parts of a hospital data storage, but this often complicates the sharing of data between network participants. Using Fabric, we want to achieve secure, shareable and authorized data storage backed by blockchain technology. Permissions should be set so only authorized peers can read secure data; Only the doctor of a patient, the patient if desired and anyone given access by the patient should be able to read a patient's data
