Forensic photo integrity

Photos that
prove
themselves.

Every photo your team captures is SHA-256 hashed and HMAC-signed at the moment of capture. Insurers and clients can verify it hasn't been touched — by anyone, including you.

Anatomy of an AuditPic photo

One photo.
Five proofs.

The image is just the start. We stamp every capture with five independent layers of evidence — any one of them can detect tampering on its own.

01
SHA-256 of pixel bytes
Burned in at capture. Recomputed on every fetch.
02
HMAC-SHA256 server signature
Server-side secret. Detects re-uploads.
03
Visible timestamp overlay
UTC, sub-second, baked into pixels.
04
GPS coordinates
With the reported accuracy radius.
05
AI-generation check
Records the result of the AI check when one has run.

Use cases

When “trust me”
isn't enough.

Insurance
SHA-256
Fingerprint per photo

Claims with proof attached

Adjusters capture damage on-site. Claims teams can check that the photo is unchanged since it was taken, without phone forensics.

Property
Time + place
Stamped on each photo

Move-in / move-out reports

Landlords and tenants both get a tamper-evident record of condition, with time and location stamped on the photo.

Journalism
UTC
Capture time

Field reporting

Editors can check that a field photo is unchanged since capture, and when and where it was taken.

Legal
Signed
Tamper-evident record

A record you can share

Every photo has a signed record and a link. Anyone can open it in a browser and see whether the photo has been changed.

Construction
Dated
Photo log

Site progress logs

Inspectors document phase completion. A dispute can be settled with the signed photo, not the email thread.

Inspections

By anyone, in any browser
