PT-SSIM: A Proactive, Trustworthy Self-Sovereign Identity Management System

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.
