Tamper-Proof Digital Evidence
Capture, seal, and verify forensic-grade evidence with hardware-level cryptographic proof. Every photo, video, and document is immutably chained from the moment of capture.
CAPTURE
Evidence captured on device
GPS, accelerometer, and device attestation are embedded at the moment of capture.
SEAL
Provio seals with hardware cryptography
Your device's Secure Enclave signs each package with ECDSA P-256.
VERIFY
Anyone can verify independently
9-step verification runs entirely in the browser. Nothing is uploaded.
BENEFIT
Court-ready evidence, always.
Tamper-proof chain of custody accepted across jurisdictions.

Why Provio
From zero to verified in minutes
Everything you need to capture, prove, and defend digital evidence.
Hardware sealed
ECDSA P-256 from your device's Secure Enclave. Unforgeable signatures tied to your hardware chip.
Chain linked
SHA-256 hash chains connect evidence sequentially. Tampering breaks the entire chain.
Authority timestamped
RFC 3161 certified timestamps provide legally-binding proof of when evidence was created.
Zero-trust verify
9-step verification runs in the browser. Anyone can verify — nothing is uploaded to our servers.
Construction
Site inspectors capture photo and video evidence on their phones. Every file is hashed, timestamped, and court-ready before they leave the site — no binders, no chain-of-custody gaps.
Insurance
Claims adjusters verify evidence authenticity through a shareable verification portal — no app install required. Tamper-proof records reduce disputes and accelerate settlements.
Legal
Litigation teams establish unbroken chain of custody with cryptographic hash chains. Evidence integrity is mathematically provable, not just procedurally asserted.
How It Works
Nine cryptographic checks run entirely in your browser. Nothing is uploaded to our servers.

Tamper-Proof Capture
Every photo and video is hashed with SHA-256 at the moment of capture. The raw bytes are signed before any processing can alter the content.
Hash Chain Integrity
An append-only hash chain links every piece of evidence into a tamper-evident sequence. Altering one entry breaks the entire chain.
EVP Evidence Packages
Self-contained archives bundle media, metadata, cryptographic signatures, and hash chain entries into a single verifiable package.
Offline-First Design
Evidence is sealed on-device using the Secure Enclave. No network connection is required at the point of capture.
Cross-Platform Verification
A 9-step verification pipeline runs entirely in the browser using the Web Crypto API. Anyone can verify evidence without installing software.
RFC 3161 Timestamps
Independent timestamp authorities provide cryptographic proof of when evidence existed, verifiable by any third party.
Pricing
Provio is free for individual evidence capture and verification while we iterate with our early users. Team and enterprise licensing is handled directly with our team.
Provio scales with teams of any size in any industry.
