Self-Sovereign Identity (SSI) represents a recent identity model that enhances the user-centric identity model. SSI utilizes distributed ledger technoloy to address the central trusted party. Devices of the Internet-of-Things (IoT) can also have digital identities. Thus, questions emerge such as how SSI can enhance the internet of things. This work investigates interoperability and data sharing problems in IoT by reviewing the literature in the related field. Next, based on our analysis, we propose an architecture that addresses the identified problems. Next, we evaluate and discuss our concept.
