Zero Trust that works across agencies

Q: What is selective disclosure?

Selective disclosure means sharing only the specific information needed for a transaction. For example, someone can prove they are over 21 without sharing their full birthdate.

Q: What are zero-knowledge proofs?

Zero-knowledge proofs are a way to confirm something is true without revealing the underlying data. They help protect privacy while still enabling verification.

Q: How do pairwise identifiers prevent tracking?

A different identifier is used for each service or verifier. This prevents activity from being linked across systems.

Q: What does zero data retention mean?

Zero data retention means that information is processed to complete a task and then immediately discarded. Data is not stored longer than necessary.

Q: How is verifier collusion prevented?

Technical controls and governance rules prevent organizations from combining data to create profiles. Pairwise identifiers make cross-service tracking difficult by design.

Q: Can credentials be verified without contacting the issuer?

Yes. Credentials can be verified locally without notifying the issuer when or where they are used, preserving privacy.

Enable secure, least-privilege data sharing between legacy and modern systems without sacrificing performance or adding friction.

Identity as the foundation for Zero Trust

Verifiable identity signals

Use cryptographic credentials, device binding, and liveness to validate users and systems with higher confidence.

Context-aware checks

Enforce real-time authentication for every request, not just at login.

Attribute-based access

Apply role, attribute, and credential-based access policies aligned to Zero Trust models.

Trust frameworks for consistent data exchange

Establish common standards for issuers, holders, and verifiers so agencies can exchange identity and eligibility data with confidence.

Use interoperable credential formats and audit trails to maintain accountability, support compliance reviews, and ensure every transaction is transparent and trustworthy.

Frequently Asked Questions

How do digital credentials support a zero-trust approach?

Each interaction requires proof that can be independently verified. Nothing is assumed to be trusted by default, and every request is checked.
