Deepfakes, Fabricated Evidence and the Future of the Claims Investigation

Deepfakes, Fabricated Evidence and the Future of the Claims Investigation

In 2025, a Warrington man was ordered to repay nearly £60,000 after submitting an insurance claim for a car crash he said had happened in Los Angeles. The claim came dressed in convincing paperwork: a forged LAPD police report, a fraudulent collision form, altered bank statements, and photographs of a damaged Range Rover that investigators later traced to a vehicle auction website. But the most revealing moment came after he was caught. Confronted with recordings of his own calls to the insurer, he denied making them and suggested deepfake technology had been used to frame him. Forensic voice analysis proved otherwise.

That defence, not the fraud itself, is the story. We have entered a period in which fabricated evidence is cheap to produce and genuine evidence is easy to deny. Both halves of that equation matter to anyone who investigates, litigates or pays claims.

Fabricated evidence has become an industrial product

Creating a convincing fake once required skill, software and time. It now requires a prompt. Research by identity firm Signicat found that deepfake-based fraud attempts rose by around 2,100% in three years, and synthetic media now accounts for roughly 6.5% of detected fraud attacks across financial services. The same tools generate invoices, medical reports, damage photographs and even live video that can pass a busy claims handler’s eye without difficulty.

The backdrop is an insurance fraud problem that was already substantial. The industry detected around 84,400 fraudulent claims worth £1.1 billion in a single year, and those are only the ones that were caught. What changes with generative AI is not the motive but the economics: a persuasive evidence package that once took days of effort can now be assembled in minutes, at effectively no cost, and at scale.

The liar’s dividend: when real evidence gets denied

The subtler danger runs in the opposite direction. Once the public knows that video and audio can be convincingly faked, every piece of genuine evidence acquires a ready-made rebuttal. Academics call this the liar’s dividend, and the Warrington case shows it is already being deployed in British claims. Expect to see it aimed at surveillance footage, recorded interviews, doorbell video of attempted service and bodyworn camera evidence.

The industry is taking the threat seriously. At a major travel insurance conference in Brighton this year, delegates were walked through a staged skiing accident claim in which manipulated footage and live deepfake interactions convincingly supported a fraudulent claim, overturning the comfortable assumption that seeing is believing. Many claims processes still rest on uncontrolled, user-submitted evidence, which is precisely the material that is now trivial to fabricate.

The courts have not lowered the bar, and nor should investigators

None of this changes the legal consequences of fabrication. Submitting false evidence in support of a claim remains fraud by false representation under the Fraud Act 2006, and verifying a statement of case or witness statement known to be false is a contempt of court under CPR Part 32. What has changed is the evidential terrain on which those battles are fought. Where authenticity was once assumed and rarely tested, it is becoming the first question rather than the last. A photograph is no longer proof of anything on its own; what increasingly matters is who captured it, on what device, when, and how it has been handled since.

Detection software will not carry that burden alone. Tools that perform impressively on laboratory datasets see their accuracy fall sharply on real-world claims media, which is compressed, poorly lit and passed through multiple platforms before an insurer ever sees it. The arms race between generation and detection will continue, and it would be unwise to bet the outcome of litigation on it.

Provenance beats pixels

This is where professional investigation quietly becomes more valuable, not less. A claimant-submitted image has no provenance. Evidence gathered by a trained investigator does: a named, accredited individual who attended a location at a recorded time, observed events first-hand, captured footage on controlled equipment, preserved the original files and metadata, and can stand in the witness box and be cross-examined on all of it. Synthetic media has no answer to a human witness with a contemporaneous, documented trail.

For insurers and solicitors handling suspect claims, that means the emphasis shifts towards independent corroboration. Professionally conducted surveillance tests whether the injury, loss or lifestyle presented in a claim matches observable reality. Wider bespoke investigations can verify the people, companies and documents behind an evidence package: whether the garage that issued the invoice exists, whether the witness lives where they claim, whether the photographs surface elsewhere online. Fabricated evidence tends to be internally polished but externally hollow, and it is the external checks that expose it.

The takeaway

Deepfakes will not make investigation obsolete. They make lazy verification obsolete. As fabricated evidence becomes indistinguishable from the real thing on screen, the value migrates to what cannot be generated: physical attendance, controlled capture, chain of custody, and sworn human testimony. The claims industry spent a decade optimising for speed and frictionless self-service. The next few years will be about restoring just enough friction, in the right places, to keep the truth provable.

Frequently Asked Questions

Can deepfake images and videos really pass as genuine claims evidence?

Yes. Modern generative tools produce photographs, documents and video that routinely deceive human reviewers, and detection software performs far less reliably on real-world claims media than on test datasets. That is why authenticity is increasingly established through provenance, meaning who captured the evidence and how it was handled, rather than through visual inspection alone.

What happens if someone submits fabricated evidence in a UK claim?

Submitting false evidence in support of a claim can amount to fraud by false representation under the Fraud Act 2006, and false statements verified by a statement of truth can be punished as contempt of court. Courts can also strike out claims, order repayment and award costs against the dishonest party.

Does the rise of deepfakes make surveillance evidence less valuable?

The opposite. Surveillance gathered by an accredited investigator comes with the things synthetic media cannot fake: a named witness, contemporaneous notes, controlled equipment, preserved originals and a documented chain of custody. As claimant-submitted material becomes easier to fabricate, independently gathered evidence becomes one of the few categories a court can safely rely on.

How can insurers and solicitors respond to a suspected deepfake?

Do not rely on the media alone. Test the claim against the outside world: verify the people, businesses, locations and documents behind it, run reverse searches on imagery, and where appropriate instruct independent surveillance or enquiries. Fabricated evidence is usually convincing in isolation but falls apart under external corroboration.
