Decentralized Medical Healthcare Record Management System Using Blockchain

The possibilities and benefit of using distributed ledger technology for storing and protecting patient medical information is greatest in the health care industry, which is one of the primary industries in this regard. Blockchain technology is being used by several companies. Inorder to protect the security and privacy of its people’ personally identifiable information and to promote the use of blockchain technology, the Government of India (GoI) is eager to digitize. Using the Ethereum blockchain, we provide a solution in this study for the safe keeping of patient medical records (PMR).Our solution provides secure and hasslefree access, storage, and patient medical record sharing. We have developed the front end as well as the back end of our project using TypeScript and Next UI Users need to register themselves if they are visiting for the first time. The information shared by the user will be stored entirely in our backend applications. We have used the IPFS file system for storing and accessing files on the internet. IPFS is a file system that helps to create a permanent and decentralized method for storing and accessing files. First, a user will upload his or her document, and the document will be uploaded to the Inter Planetary File System (IPFS). Once the document is uploaded, a unique hash is returned, which is also known as a CID (content identifier). This is used to uniquely identify the uploaded file on IPFS. Then, that CID is stored in the blockchain as a private variable, so not everyone can access it. When someone can access it, we will specify the conditions.
