Step 1
Define the decision
Your service sends who is asking, what they need, which policy version applies, and channel context. The format is the same for live API calls and offline packets.
How do councils verify housing and licensing without a citizen replica database?
Housing, licensing, electoral, and discretionary schemes.
Short answer: Each decision is one API call returning yes or no with proof - councils do not need a council-wide copy of citizen records at the verification layer.
Stateless verification · No standing PII store · ML-DSA ready
Programme context
Councils and combined authorities deliver housing, social care, licensing, parking, and discretionary assistance. They must verify entitlements against central registers without becoming another national citizen database.
What teams are solving
Housing benefit, council tax support, blue badges, and event licensing each pull data from DWP, DVLA, and internal systems. Replication is slow and hard to delete when rules change.
AffixIO approach: One verification call per decision, consumed by case management and citizen portals. Electoral and concession journeys can use offline validation at polling stations and counters.
Where verification applies
- Housing benefit and council tax support
Parallel eligibility with central signals.
- Blue Badge and concessions
Disability and age proofs without medical record copies.
- Taxi, alcohol, and event licensing
Professional and criminal record binaries for committee packs.
- Electoral services
Voting eligibility with polling-station offline validation.
- Cost of living schemes
Rapid discretionary grants with fraud controls.
From request to verified outcome
The same three-step model used across AffixIO applies here: describe the decision, evaluate against sources you control, return yes or no with proof.
Step 2
Evaluate against authority
Checks run against registries and rules you authorise. Sensitive fields stay in systems you already operate wherever the design allows.
Step 3
Return yes or no with proof
The response is explicit, signed where required, and suitable for audit or partner handoff. AffixIO does not retain the request after the decision.
Where AffixIO sits in your stack
A thin stateless layer between citizen channels and core departmental systems. It answers eligibility questions; it does not replace case management, payments, or identity providers.

How teams deploy
Managed API
Connect through your API gateway with TLS, mutual authentication where required, and departmental logging.
Self-hosted
Run inside your accredited boundary when policy requires on-premise or private cloud.
Offline and edge
Validate signed proofs locally where connectivity is limited. See offline verification.
Agentic channels
Machine clients receive the same binary signals as citizen channels. See M2M verification.
Cryptography and data handling
Built for long-lived programmes that must plan beyond legacy signatures and minimise data held at the verification boundary.
Stateless by design
No long-term store of who asked or the attributes inside a request. Supports proportionate DPIA narratives.
ML-DSA ready
Artefacts can use Module-Lattice-Based Digital Signature Algorithm (ML-DSA), aligned with NIST post-quantum direction, with optional HSM-backed key ceremonies.
Zero-knowledge outcomes
Where policy allows, demonstrate that a rule evaluated to yes without exporting underlying registry content.

Common questions
Does AffixIO store citizen personal data?
No. AffixIO is stateless verification infrastructure. It evaluates a request against sources you authorise and returns a decision with proof. It does not maintain a standing database of citizens or request payloads.
Can this run offline for field teams?
Yes. Signed proofs can be validated where connectivity is limited, with reconciliation when the device or site is back online. This pattern is used across offline payment and access programmes on affix-io.com.
How does ML-DSA fit in?
Long-lived verification artefacts can be bound with ML-DSA (Module-Lattice-Based Digital Signature Algorithm), supporting post-quantum planning. HSM-backed ceremonies are available where your security policy requires them.
