Trust Flow Diagrams and e-ID

Trust flow diagrams provide a structured and practical method for translating high-level digital identity use cases into real-world implementations. By visualising how data, credentials, and stakeholders interact across systems, Trust Flow Diagrams create a common understanding of complex trust relationships and digital processes. This approach can help stakeholders design, implement, and scale digital identity solutions more effectively and consistently.

The work presented supports several important objectives for Switzerland's emerging e‑ID ecosystem:

• Increasing transparency in the operation of digital identity and trust infrastructures;
• Accelerating adoption across sectors through reusable models, shared terminology, and implementation guidance;
• Strengthening collaboration between public authorities, private organizations, and technical communities.
