Tamper-Proof Photo Evidence
Digital photos can be altered without a trace. OP embeds cryptographic provenance at capture, giving legal teams a verifiable chain of custody for every image.
The Problem
Why existing approaches aren't enough for your industry.
Photos Can Be Altered Silently
Modern editing tools leave no visible trace. Without provenance, there's no way to prove a digital photo hasn't been modified.
Chain of Custody Is Hard to Prove
Courts require evidence integrity documentation. Digital files change hands through email, cloud drives, and case management systems — each a break point.
Insurance Fraud via Manipulated Images
Doctored photos of accidents, property damage, and injuries cost the insurance industry billions annually.
How Teams Use OP
Real scenarios where embedded provenance changes the workflow.
Sign Accident and Scene Photos at Capture
Field investigators sign photos immediately. The embedded manifest locks the content hash, signer identity, and GPS/timestamp at the moment of capture.
Verify Evidence Integrity Before Submission
Before filing, verify that every photo in the evidence package matches its original signed manifest — automated, auditable, instant.
Document Chain of Custody for Discovery
Each handoff can be re-signed, creating a layered provenance chain. Opposing counsel can independently verify the entire history.
How It Works
Three steps to provenance-backed content.
Upload
Upload your image, video, or document. Any standard format works.
Sign & Verify
OP embeds a C2PA manifest with signer identity, timestamp, and tamper-evident hash.
Trust
Anyone can verify the file's origin, chain of custody, and integrity — instantly.
