# Self-Sovereign Identity (SSI) Ecosystem for Facility Management

> The SSI ecosystem at Studio6 in the Blockchain Real Lab demonstrates practical applications of digital identity solutions in facility management. Employees and visitors can use self-managed digital identities to open doors, control lighting, and pay for coffee. This demo showcases the viability of Self-Sovereign Identity technologies for secure and user-friendly facility services.

## Description

The Blockchain Reallabor Hürth operates an SSI ecosystem (Self-Sovereign Identity) as a productive demonstrator in its own building (Studio 6, euronova CAMPUS). Employees and visitors receive verifiable credentials on their smartphones; smart contracts verify permissions and control access to various areas. No central user database is required — users control their own credentials.

Self-Sovereign Identity (SSI) is a paradigm shift in digital identity management: instead of a central provider (Google, Microsoft, government authority) managing identities, users control their own verifiable credentials on their smartphone. The Blockchain Reallabor Hürth implemented this concept as a live demonstrator in its own building: employees of the Reallabor, the AI Village, and other projects on the euronova CAMPUS use SSI-based digital IDs for access control. A visitor scans a QR code, proves a relevant attribute (e.g. "Employee of Fraunhofer FIT" or "registered visitor") — without revealing more data than necessary. The system is based on the same technical foundations as the European Digital Identity Wallet (EUDI). Sabine Kolvenbach from the Blockchain Reallabor team prototypically realised SSI ecosystems as proof-of-concept for general life and business areas. The Studio6 SSI ecosystem is part of the SapientBlock project (funded by BMWK/NRW, Prof. Wolfgang Prinz, Fraunhofer FIT).

## Benefits

- Reduced administrative costs through automated authorisation and fewer manual processes.
- Increased security through decentralised authentication without central points of attack.
- Better data protection through Self-Sovereign Identity principles.
- Simplified user experience through a single digital identity for various services.
- More convenience through a single identity for all building functions.

## Challenges

- Companies must invest in new infrastructure and may need to replace existing systems.
- The technology is still new and requires training for users and administrators.
- Integration into existing building technology can be complex and costly.
- Employees must get used to new digital identity systems and use corresponding apps or hardware.

## Technology foundation

Self-Sovereign Identity is based on blockchain technology and enables users to manage and control their digital identities themselves. The technology is particularly suitable for facility services, as it allows secure authentication without central data storage while protecting users' privacy.
