Blockchain based Smart Healthcare System

In this piece, an architecture and a mechanism for building a blockchain-based EMR system are suggested. In addition, the blockchain variety that might serve this function and its justification are shown. It is recommended that Hyperledger Fabric and Hyperledger composer be utilized to implement the proposed method. Patients may actively manage their medical records here. Security and privacy concerns have also been addressed. The patient may manage who has access to their medical information using doctored and can remove that authorization at any moment. If the patient’s medical records are maintained current and available via the blockchain network, the doctor will be able to perform a more complete study and evaluation of the patient’s health. The paper’s shortcomings may primarily be broken down into three categories. The system is not scalable, to start. Second, only patients and physicians are allowed to participate. Finally, the database’s ability to hold information is severely constrained. Only a few fundamental diagnostic details—all of which are text-based—are taken into account. There are two components to the upcoming work. The suggested solution is essentially a prototype to obtain a sense of how blockchain works when it is connected with EHR. The first step is to include additional participants, such as a hospital or an insurance provider. The system must then be scaled up and an off-chain database must be maintained in order to keep the actual prescription in the form of an image or another format. Additionally, efforts to find a better blockchain, such as one that is layered or hybrid, will continue.
