Abstract: The arrival of blockchain technology has made a revolution in the field of cybersecurity. Since on the internet, almost every interaction involves some digital identity, therefore the ways needed to protect the digital identity over the internet becomes stronger. In this paper, a blockchain based identity and access management system 'MedSecureChain' has been implemented on a medical ecosystem. An OAuth-based authentication mechanism is used to provide delegated access, so as to protect and provide the control over user data. Further, a document verification system using interplanetary file system (IPFS) and blockchain technology has been proposed. IPFS is used to store the users' data in decentralised manner thus reducing the size of the data. The proposed system provides security and privacy to the identity of the user by using smart contracts. The use of blockchain helps in decentralising the system thus eliminating the control of single authority over the data.
