Verified Report Photos for Insurance Appraisers and Adjusters

Every insurance claim of any size ends up as a set of photographs and an argument about them. A motor appraiser photographs a dented quarter panel, and the repair estimate follows from those frames. A property adjuster documents a flooded basement, and the settlement follows from that. Months later, a repair shop, a policyholder or a court may ask whether a photograph shows what the report says it shows, and whether it was taken when the report says it was. The photograph usually cannot answer. It is a JPEG with metadata that anyone can edit.

The photographs an insurer's own appraisers, adjusters and surveyors take do not have to stay that way. When the camera also records a RAW file, or the photo is taken with Lumethic Capture on an iPhone, each report photo can be checked against what the sensor recorded, and the check can travel with the photo as a record. That changes the shape of a dispute. The question stops being "is this photo real?" and becomes "here is the record of what was checked, and when."

Whose Photos This Covers

This is for the photographs taken by people the insurer pays or appoints: motor damage appraisers, property adjusters, surveyors and inspectors, repair partners documenting their work, and the valuation photographers whose pictures underwrite a policy on a watch, a painting or a classic car. These people shoot with cameras that can record RAW, or with a phone the office can prescribe. Their photographs decide the larger sums, and they are the ones that get contested.

It is not a way to screen the photos policyholders upload after a loss. Those arrive as JPEGs from whatever phone the claimant owns, usually recompressed by the upload portal, with no RAW behind them. The Lumethic method needs the RAW, so it does not apply to them.

What the Check Records

A camera set to record RAW and JPEG together writes two files per shutter release. The RAW holds the sensor data before any processing; the JPEG is the camera's rendering of it. Lumethic takes both files and compares them.

The comparison looks at three things. Whether the RAW carries the noise structure and signal distribution of a physical sensor. Whether the delivered JPEG matches what that sensor recorded, so that content added, removed or moved after capture shows up as a difference. And whether the metadata of both files agrees with itself and with the camera model, which exposes edited timestamps and stripped fields. A separate check looks for the traces a photograph of a screen or a print leaves behind; that signal is reported as found, not found, or inconclusive, and it never carries a result on its own.

When the comparison passes, Lumethic signs the JPEG with a C2PA credential that records what was checked, when, and with which version of the method. Any C2PA-capable reader can open that record. Lumethic does not judge what the photo looks like or whether the damage is plausible; it records how the delivered photo relates to its RAW. The RAW is used for the check and for nothing else, and processing runs on infrastructure in the European Union. The data handling page describes this in the detail a procurement review needs.

None of this requires new equipment. Appraisers who already carry a camera need only enable RAW recording; our camera setup checklist for evidence photography covers the settings. The verification runs through the web upload, the Lightroom plugin or the API, whichever fits the office.

From "Is This Real?" to "Here Is the Record"

Without a record, a contested report photo turns into a debate about the image itself: someone points at a shadow, someone else at the file date, and each side brings an opinion. The appraiser's word is the only thing holding the photo in place.

With a verified photo, the appraiser can hand over the record instead. It states that the delivered photo was compared against a camera RAW or a Capture recording, which checks were run, what they found, and when the check took place. The other side can open the credential in a standard reader and see the same thing. The argument moves on to what the photo shows, which is where an appraisal dispute belongs.

Where Verified Photos Fit in a Claim

Motor damage appraisal is the clearest case. An appraisal report carries dozens of photographs and is routinely challenged over repair cost, the total-loss threshold and settlement on a notional repair. An appraiser who verifies the report photographs delivers a file in which each image carries a record of its capture. The question of whether a scratch was already there, or whether a photograph predates the accident, then has a document to start from.

Property adjustment works the same way at larger sums. Staff adjusters and external adjusting firms photograph storm, fire and water damage, and the settlement rests on those frames. A credential on each photograph gives the file a record to point to when a policyholder disputes the extent of damage or a reinsurer audits the claim.

Underwriting documentation of valuables is the case with the longest memory. Jewellery, art, instruments and classic cars are insured on the basis of a valuation with photographs. When a claim arrives years later, the question is what condition the item was in at the start of the policy. A photograph verified and signed at the time gives that question a record. Where the date itself must be fixed by an independent party, a trusted timestamp does that job, as described in how to prove a photo existed on a certain date.

Repair documentation and surveys complete the picture. Repair partners photograph work before and after, and hail assessors, marine surveyors and construction inspectors document conditions on site. Wherever a professional the insurer appoints holds the camera, the same method applies.

Capturing on an iPhone

Not every appraiser carries a camera, and repair shops rarely do. For iPhone, Lumethic Capture records the unprocessed sensor mosaic alongside the photograph, which gives the verification the RAW it needs. The app attests the device through Apple's App Attest and signs the result on the phone. Today that attestation is reported as evidence rather than enforced as a gate, and we say so rather than imply otherwise. An Android version is in development.

What the Carrier Receives

A carrier does not need to integrate anything to benefit. The credential travels with the photograph, and a claims handler can open it in any Content Credentials reader and see the verification record. The simplest first step for a carrier is a stated preference: report photographs from appointed appraisers should carry a Lumethic credential. That costs the carrier nothing and binds only the appraisers it already works with.

The result is a set of findings with explicit boundaries, not a score. A photo that does not pass goes to a person for review. Lumethic does not decide claims and is not built to. The decision stays with the handler, who now has a record to work from.

For procurement, the points that usually matter are covered on the trust and security pages: purpose limitation, processing in the EU, deletion in line with the GDPR, and a data processing agreement on request.

What This Does Not Do

It does not screen claimant uploads. A JPEG on its own, without a RAW or a Capture recording behind it, cannot be verified, and Lumethic does not put a score on it.

It does not decide claims. Findings are evidence for a person to weigh.

It does not replace an inspection. A verified photo shows that the delivered image matches what the sensor recorded. Whether the damage is consistent with the reported event remains the appraiser's judgment.

Run a Pilot with Your Office

The most useful first step is small: one appraiser office or one adjuster team, verifying the photos in its reports for a few months, on the product as it exists today. Camera shooters switch on RAW+JPEG, iPhone users take report photos with Lumethic Capture, and every report photo goes out with a credential. At the end, the office knows how the verified reports fared against its usual queries and disputes.

Frequently Asked Questions

Our appraisers shoot JPEG only. Does that rule this out? For those photographs, yes. Verification needs the RAW. Most cameras record RAW and JPEG together after a single menu change, and Lumethic Capture provides the equivalent on iPhone.

Can we use this to check the photos policyholders send us? No. Those photos arrive without a RAW, and the method compares a photo against its RAW. Lumethic is for the photos your own appraisers, adjusters and surveyors take.

How large are the uploads? A camera RAW runs between 25 and 80 MB, and an appraisal has dozens of them. Offices with high volumes use the API or the Lightroom plugin rather than the browser.

Can the credential be read without Lumethic? Yes. It is a Lumethic-attested C2PA credential in the standard format, so any C2PA reader can display it; until Lumethic is on the C2PA trust list, standard tools may show the signer as "unrecognized". The Lumethic verification page adds the detailed findings.

Does this help with the EU AI Act? Not directly. The Act's transparency duties fall on providers and deployers of generative systems, not on insurers receiving photographs. A verified photograph is useful because it gives a dispute a record to work from, not because a regulation demands it.
