SIU link analysis · Entity-resolved vehicle–person graph

Your scoring engine reads claims one at a time. Rings don't file claims one at a time.

Ringfence detects organized fraud by its structural fingerprint — the same people, vehicles, and addresses recurring across "unrelated" claims — on an identity graph built from entity-resolved vehicle and person data. Output: ranked, explainable investigative leads for your SIU.

The blind spot

Claim-level scoring catches opportunists. It structurally cannot see a ring.

Organized rings coordinate across many claims, policies, and often multiple insurers at once. Reviewed one file at a time, every individual claim can look ordinary — the fraud only exists at the network level. Incumbent tools score in isolation or link on fuzzy name matches. The layer that's missing is identity.

What isolated scoring sees

A rear-end collision. Three occupants. Soft-tissue injuries, an attorney letter, a clinic bill. Nothing anomalous. Paid.

What the identity graph sees

The "victim" in this file was the at-fault driver in two others. Same garaging address as four claimants across three files. Same attorney on all of them. All filed inside one 60-day window, in one venue, days after policy inception. That's not a claim. That's a node.

Validated in federal court

An April 2026 federal complaint reads like our feature list.

Uber and Liberty Mutual sued a 14-person, 8-provider ring that staged collisions against rideshare drivers in New York — at least eight incidents over 19 months, $312,979 paid out before it was caught. The evidence that broke it open is exactly what Ringfence scores on every claim, automatically.

// It took 19 months and a federal lawsuit to see this ring. The topology was machine-visible by claim three.

Adversarial benchmark

Tested against data built to fool it. Zero false positives across twelve books.

Twelve randomized synthetic books, each ~600 claims and ~1,000 people, seeded with everything that trips naive fraud models: families sharing one address, apartment buildings collapsing strangers onto one street, a handful of clinics handling huge legitimate volume, honest repeat claimants — and six rings per book hiding among their members' ordinary claims. Precision held at 100% on every book: not one household or building was ever flagged. Mean ring recall: 99% with the full signal set — 96% on structural signals alone. Every lead ships with the signals that produced it, so an investigator sees why before spending an hour on it.

Your claims never become our product.

Ringfence is an analysis layer, not a data broker. Claims stay under your control; we bring the identity-resolution layer that makes the ring topology visible.

01 / FEED

Claims extract

Claim ID, date, venue, loss/paid, parties, attorney, clinic, shop. Flat file or API. Under a data-processing agreement, inside your security requirements.

02 / RESOLVE

Identity graph

Parties and vehicles are entity-resolved — one node per real person, VIN, and address — so "J. Smith" at three addresses stops being three strangers.

03 / LEAD

Ranked SIU queue

Communities scored on seven structural signals. Your investigators get a ranked, fully-explained lead file — and make every call themselves.

Built inside the lines

Compliance is the architecture, not a disclaimer.

DPPA

Permitted purpose, by design

Insurance anti-fraud investigation is an explicitly permitted use of motor-vehicle records under the Driver's Privacy Protection Act. This lane is the clean one.

FCRA POSTURE

Leads, never determinations

Output is an investigative lead for a licensed SIU professional — probabilistic, explainable, human-in-the-loop. Ringfence never recommends denying, delaying, or rescinding anything about anyone.

DATA HANDLING

Your book stays yours

Processing under DPA, scoped to the engagement. No cross-customer pooling of your claims. Deliverables are leads, not datasets.

Design partner

First book scan is free for one carrier or TPA.

The trade

You bring a claims extract under NDA + DPA. We run the full ring scan and hand your SIU a ranked, explained lead file. In exchange: case-outcome feedback and, if the leads hold up, a reference. A denied staged claim is a number your CFO can name to the dollar — you'll know exactly what this was worth.
