Utilities eligibility verification

Utilities need clear eligibility at plant gates, field jobs, and customer programme boundaries. AffixIO issues signed allow or deny outcomes with Merkle-anchored audit.

Merkle-anchored outcomes

Utilities eligibility verification confirms whether a crew member, contractor, or customer qualifies for access or a programme outcome without copying personal records into every operational system.

The challenge

Operational identity sprawl

Field systems and contractor portals accumulate identity fragments that are hard to audit after incidents.

Fragmented clearances

Multiple systems disagree on who is cleared today.

Customer programme PII

Eligibility services copy sensitive customer attributes.

Contractor churn

Short engagements leave stale credentials in vendor stores.

Use cases

Utilities scenarios

Use where a binary eligibility decision must be proven at the edge.

Plant access

Shift and role predicates at the gate.

How verification works

  1. 01

    Issue

    Policy authority defines a Noir circuit for the rule set. Witness inputs come from systems that already own the records.

  2. 02

    Bind

    Proof is bound to event context: programme ID, expiry, geography, and anti-replay nonce. ML-DSA-65 signature applied at issue.

  3. 03

    Present

    User, agent, or device presents the credential via API call or secure QR at the service boundary.

  4. 04

    Verify

    Verifier receives allow or deny plus Merkle reference. No personal data retained at the verifier by default.

FAQ

Frequently asked questions

How do auditors check a decision?

Use the Merkle reference returned with allow or deny.

Can this integrate with existing IAM?

Yes, as a verification boundary via API or SDK.
