Every photo is a claim. Verifact makes it proof.
The full signature chain — device identity, recorded location, capture time, file integrity — is re-checked in seconds.
01 — The problem
Metadata is testimony. Testimony can lie.
Claims run on photos, and photos are taken on trust. EXIF data can be rewritten in seconds, a screenshot strips everything, and generative AI now produces convincing damage photos on demand. Looking closely is no longer a defence.
Editable
EXIF is not evidence
Timestamps and GPS tags are plain text. Any phone app can rewrite them without a trace.
Strippable
Screenshots erase history
One screenshot and every clue about origin is gone — while the image looks untouched.
Generatable
Fakes are now free
AI image tools make fabricated damage cheap, fast, and hard to spot by eye.
02 — The approach
Don't inspect the photo. Verify its chain.
Verifact seals every photo at the moment of capture and lets anyone re-check that seal later. Four links, each one mathematical:
01
Capture
Taken in a Verifact app. Location and network time recorded at the shutter.
02
Sign
Sealed in a C2PA manifest with a key held in the phone's secure hardware.
03
Timestamp
Countersigned by an independent RFC 3161 timestamp authority.
04
Verify
Re-checked by anyone, anywhere, in seconds.
03 — The platform
One chain, end to end.
Capture apps for surveyors and claimants, a portal for claims teams, portable signed certificates, and an API to wire it into your systems.
Capture
Surveyor & claimant apps
Hardware-attested capture in the field — by your surveyor, or by the policyholder from a simple link.
Operate
Insurer portal
Claims, evidence, verification history, and triage in one workspace built around the claim.
Extend
Certificates & API
Signed PDF certificates anyone can verify, and scoped API keys for programmatic verification.
04 — Standards
Open standards. Independent proof.
The proof format is open, the signatures are standard, and the timestamps come from an authority we do not control. You never have to take our word for it.
