In today's complex Internet platform, online users need help to protect their online identity. Only sometimes, websites are very transparent about how user data will be collected, stored and processed by them. Sometimes Internet entities collect more online user information than required. These entities often share user identity-related data with third parties without consent. Existing traditional identity schemes need to be improved to stop and counter new ways of digital identity theft and fraud. Blockchain is a promising technology to strengthen the preservation of online users’ digital identity due to its decentralised nature and robust data security features. In this paper, we proposed and implemented a generic blockchain-IoT-based self-sovereign identity management framework called ChainDiscipline. We have demonstrated the framework's operability and functionality by implementing healthcare and smart home data management-based use cases.
