Forensic photo integrity · since 2024

Photos that
prove
themselves.

Every photo your team captures is SHA-256 hashed and HMAC-signed at the moment of capture. Insurers, courts, 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 reported accuracy radius. Spoof-resistant.
05
AI-generation detection
Off-device model flags synthetic content.
