Insurance fraud prevention has always been a critical industry-wide issue, but never before has fraud been supercharged by artificial intelligence on such a broad scale.
A major Australian insurer was dealing with a rise in sophisticated, backdated, and AI-altered claim documents following severe storm events. Fraudsters increasingly submitted inflated repair quotes or contractor reports dated earlier than the insurer’s official assessments. Metadata alone was unreliable, and traditional fraud-detection tools could not conclusively determine when documents actually existed.
To strengthen their insurance fraud prevention workflow, the insurer implemented TimeBinder across all catastrophe-event assessments. On-site assessors timestamped photos, videos, measurements, and inspection notes at the moment they were captured and uploaded, creating independent, tamper-proof proof of when the evidence existed.
Months later, a claimant submitted an updated contractor report showing significantly more severe structural damage and a date that allegedly pre-dated the insurer’s original inspection. The insurer compared the claimant’s documents with their own blockchain-anchored evidence and immediately identified the timeline discrepancy.
What Was at Stake
- A potential six-figure fraudulent payout
- Escalation to AFCA over conflicting account of damage
- Reputational risk if the insurer appeared to mishandle the claim
- Compliance risk around fair and evidence-based dispute decisions
- Ongoing exposure to increasingly sophisticated digital manipulation

How TimeBinder Was Applied
1. Inspection evidence was timestamped on-site
The insurer’s assessor captured:
• photos and videos
• moisture and structural readings
• roof and frame inspection notes
• a preliminary damage summary
Each file was hashed locally on the assessor’s device and anchored to the Bitcoin blockchain, producing a Proof of Time Certificate including:
• SHA-256 file hash
• blockchain transaction reference
• UTC timestamp
• verification link and QR code
This created a permanent, immutable record of the property’s condition on Day 1.
2. The claimant later submitted a backdated contractor report
Weeks after the event, the claimant produced a contractor report stating:
• the damage was significantly more extensive
• the damage was “pre-existing” or older than the insurer claimed
• the report was allegedly prepared before the assessor’s visit
This is a common tactic in insurance fraud: backdating documents to inflate liability or shift responsibility for damage.
3. The insurer compared both sets of evidence
TimeBinder played a decisive role here.
The insurer did not attempt to “hash-match” the claimant’s report.
Instead, they relied on the strength of their own earlier, verified evidence.
The blockchain-anchored inspection files proved:
- The insurer’s verified assessment existed on Day 1.
- The assessor’s photos showed the damage was far less severe at that time.
- The newly claimed “structural failure” could not have existed on Day 1 if it only appeared weeks later.
- The contractor report’s date was inconsistent with the verified timeline.
Because the insurer could establish, immutably and independently, what the property looked like on Day 1, the contractor report could not be accepted as an accurate historical record.
The investigation concluded that the contractor report was either:
• backdated
• based on later damage
• or created using incorrect information
In all cases, the insurer’s blockchain-verified evidence was stronger, more credible, and more defensible.
Proof Artifact Used
Artifact: Proof of Time Certificate (PDF)
Blockchain Reference: Bitcoin
Verification Method: File-hash comparison against insurer’s own Day 1 evidence
File Types: JPEG, PDF, MP4, inspection notes
Result: Verified timeline inconsistency — fraudulent claim prevented

Outcome — Why Insurance Fraud Prevention Requires Immutable Timestamps
• Fraudulent claim prevented: Yes
• Incorrect payout avoided: $112,000+
• Time to resolution: Under 72 hours
• Escalation to AFCA avoided: Yes
• Legal defensibility strengthened through verifiable, independent timestamps
• Workflow expanded to all catastrophe-event assessments
By anchoring inspection evidence to the blockchain, the insurer gained a reliable, court-ready timeline that could not be altered, manipulated, or disputed. Instead of arguing over conflicting documents, they relied on independent mathematical proof.
TimeBinder now forms a core part of the insurer’s insurance fraud prevention strategy for property, motor, and contents claims.

Customised for the Insurance Sector
TimeBinder.io provides insurers with immutable blockchain timestamps for claims evidence, assessment reports, policy documents, repair invoices, photos, and customer correspondence. These timestamps create verifiable proof of when files truly existed, strengthening insurance fraud prevention processes and safeguarding against altered, backdated, or AI-generated claim materials.
Key Takeaway
This case gave the insurer a powerful practical advantage: every claim file now comes with cryptographic, blockchain-verified provenance. Instead of arguing about “who changed what and when,” claims officers can prove it decisively. TimeBinder now forms part of the insurer’s fraud-detection strategy across vehicle, home, and contents claims — especially critical as AI-generated forgeries become more common.
Insurance fraud prevention is no longer just about spotting inconsistencies. It requires tamper-proof proof of when claim evidence truly existed. TimeBinder gives insurers an immutable audit trail that protects decisions, reduces payouts on fraudulent claims, and stands up to scrutiny from regulators, courts, and dispute resolutions.
