| Abstract | In the Internet of Things (IoT) context, a considerable quantity of data flows from sensors to centralized servers, holding sensitive information related to users. Unfortunately, how servers store these data instances is usually poorly documented and does not offer any transparency to the users but may pave the way to possible privacy violations. Web decentralization is a prominent solution to cope with these issues and legal obligations regarding data protection so that multiple domains are progressively adopting it as the principal technological enabler. The IoT is not among them yet, as a centralized approach is still the most common one; however, moving data location away from servers to prefer gateways or directly to devices closer to users and under their direct control can realize a more decentralized approach and alleviate the issues related to performance, throughput as well as data protection. This paper aims to exploit existing data decentralization solutions, like Social Linked Data (Solid), to define a more distributed data management for IoT and propose a proof-of-concept implementation of a Smart City platform where users can store and directly manage data produced by public or private IoT devices. Despite providing decentralized data handling, Solid is still affected by a centralized identity management and authentication implementation represented by OpenID Connect. Therefore, to fulfill our vision of a decentralized IoT, we also investigate how decentralizing authentication within Solid and a new user-centric approach based on Self-Sovereign Identity (SSI) represents a promising solution. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG. |
