Decentralized Identities for Self-sovereign End-users (DISSENS)

This paper describes a comprehensive architecture and reference implementation for privacy-preserving identity management that bucks the trend towards centralization present in contemporary proposals. DISSENS integrates a technology stack which combines privacy-friendly online payments with self-sovereign personal data management using a decentralized directory service. This enables users to be in complete control of their digital identity and personal information while at the same time being able to selectively share information necessary to easily use commercial services. Our pilot demonstrates the viability of a sustainable, user-centric, standards-compliant and accessible use case for public service employees and students in the domain of retail e-commerce. We leverage innovative technologies including self-sovereign identity, privacy credentials, and privacy-friendly digital payments in combination with established standards to provide easy-to-adapt templates for the integration of various scenarios and use cases.
