Abstract
Digital identity management (DIM) systems have become challenging, especially, given the current progression in ubiquitous environments enclosing cooperative Internet of Things (IoT) devices, individuals, and organizations. Self-sovereign identity (SSI) has recently surfaced to manifest the notion of decentralized DIMs enlivened by users’ autonomy. This article presents a proactive, trustworthy solution for managing digital users’ data and identity information without risking its integrity, security, privacy, and confidentiality. Accordingly, we propose a decentralized SSI-enabled cloud storage model that enables secure access control and frequent data integrity checking (IC) mechanism. The presented model ensures the resiliency of SSI-enabled operations, including users’ registration, data identification, external information distribution, IC operations, identity information authentication and verification, and decentralized external and shareable operations.
