Privacy-Preserving Image Verification

You can't trust what you see anymore.
But you can prove it's real.

AI makes fake images indistinguishable from real ones. Metadata can be stripped. Watermarks can be forged.

Rial uses zero-knowledge cryptography to prove an image is authentic—without exposing sensitive data or relying on central authorities.

The Trust Crisis in Digital Imagery

Every industry that relies on photos for verification is under attack from AI-generated fakes and manipulation.

Legal

Legal & Compliance

Digital evidence is inadmissible if authenticity can't be proven. Chain-of-custody breaks with metadata tampering.

Courts reject 40% of digital evidence
Insurance

Insurance Claims

Fraudsters submit AI-generated damage photos. Adjusters can't tell what's real. Claims costs skyrocket.

$12B lost annually to photo fraud
Journalism

Journalism & OSINT

Fake news spreads through manipulated images. Deepfakes erode trust. No reliable way to verify sources.

73% don't trust online images
Enterprise

Enterprise Audits

Field inspections, deliveries, and documentation photos can be fabricated. Compliance becomes impossible.

2.1M fake inspection photos/year

Why Current Solutions Fail

❌
Metadata — Can be stripped or forged in seconds
❌
Watermarks — AI removes them or generates fake ones
❌
AI Detection — Degrades within weeks as generators improve
❌
Central Authorities — Single points of failure, privacy nightmares

Cryptographic Proof, Not AI Guesswork

Rial uses zero-knowledge proofs to verify image authenticity mathematically—without exposing the original photo or sensitive metadata.

1

Capture

Image captured with our mobile app. Device hardware (Secure Enclave) generates cryptographic signature.

iOS Secure Enclave • App Attestation
→
2

Proof Generation

Zero-knowledge circuit creates proof of authenticity. Original image never leaves device.

Circom 2.0 • Groth16 • Halo2
→
3

Verification

Anyone can verify authenticity cryptographically. No central authority. No metadata exposure.

C2PA Compatible • Privacy-First

CheckCryptographically Verified

Mathematical proof of device origin, not AI detection. Resistant to forgery without breaking advanced cryptography.

LockPrivacy-Preserving

Prove authenticity without revealing GPS, timestamp, or image content. Zero-knowledge by design.

ShieldDecentralized Verification

Verification works peer-to-peer. Reduces single points of failure.

MobileHardware-Backed Security

Keys stored in iOS Secure Enclave or Android Keystore. Device attestation helps detect tampering.

Built for Industries That Can't Afford Fake Images

Insurance

Insurance & Claims

Problem: Fraudulent damage photos cost insurers billions annually.

Solution: Cryptographically verify photos were taken in-field, not AI-generated.

  • Prove image captured on-site with GPS verification
  • Timestamp proof prevents backdating
  • Allowed edits (crop, resize) tracked cryptographically
Use Case: Helps reduce fraudulent claims
Legal

Legal & Compliance

Problem: Digital evidence inadmissible without proven chain-of-custody.

Solution: Cryptographic proof of origin, integrity, and transformation history.

  • Designed for legal proceedings (consult counsel for admissibility)
  • Complete audit trail of edits
  • Hardware attestation proves capture device
Use Case: Supports chain-of-custody requirements
Journalism

Journalism & OSINT

Problem: Fake news spreads through manipulated imagery. No way to verify sources.

Solution: Verify original photos cryptographically without revealing sources.

  • Protect journalist identity with privacy-preserving proofs
  • Verify image integrity for fact-checking
  • Helps detect suspicious images
Use Case: Privacy-preserving source verification
Enterprise

Enterprise Audits

Problem: Field inspections, deliveries, documentation can be faked.

Solution: Prove work completion with cryptographically signed photos.

  • Verify field technicians were on-site
  • Prove delivery documentation authenticity
  • Supports compliance audit requirements
Use Case: Compliance-ready audit documentation
Social Media

Social & Messaging Platforms

Problem: Users don't know if images are real or AI-generated.

Solution: Label verified real-world media without exposing metadata.

  • Show "verified device origin" badge on authenticated photos
  • Protect user privacy (no GPS/time exposure)
  • Helps combat misinformation
Use Case: Content authenticity labeling
Construction

Construction & Infrastructure

Problem: Progress photos can be backdated or fabricated for billing.

Solution: Time-stamped cryptographic proof of project milestones.

  • Verify construction progress for draws
  • Helps prevent billing fraud with timestamped proofs
  • Safety compliance documentation
Use Case: Timestamped milestone verification

How Rial Works

Advanced cryptography meets mobile-first design. Enterprise-grade security that just works.

Zero-Knowledge

Zero-Knowledge Image Proofs

Prove image integrity and allowed transformations without exposing the original photo.

  • Based on Circom 2.0 with Groth16 circuits
  • Halo2 integration for recursive proofs
  • Support for multi-step transformations (crop, resize, grayscale)
  • Privacy-preserving by design
Mobile

Hardware-Backed Security

Keys stored in iOS Secure Enclave and Android Keystore (TEE/StrongBox). Device attestation ensures only legitimate clients generate proofs.

  • Private keys never leave device hardware (Secure Enclave/StrongBox)
  • iOS App Attestation & Android Play Integrity API
  • All images cryptographically signed at capture
  • Camera source verification (detects screenshots)
C2PA

C2PA Compatibility

Outputs verifiable C2PA-style claims with Merkle roots and timestamps.

  • Integrates with content authenticity standards
  • Adobe, Microsoft, BBC consortium compatible
  • Future-proof metadata format
  • Cross-platform verification
Security

Fraud Detection Pipeline

Multi-layer verification catches screenshots, stock imagery, and GPS/time spoofing.

  • Screenshot detection via system metadata
  • Reverse image search for stock photos
  • NTP time validation + location triangulation
  • Optional AI detection augments cryptographic proofs

What Rial Verifies (And What It Doesn't)

We provide technical verification of device authenticity and capture metadata. Understanding our scope helps you use Rial effectively.

✓ What We Verify

  • ✅ Device authenticity (hardware attestation)
  • ✅ Capture timestamp accuracy
  • ✅ GPS coordinates (when enabled)
  • ✅ Image transformation history
  • ✅ Cryptographic chain of custody

✗ What We Don't Verify

  • ❌ Content truthfulness
  • ❌ Whether scenes were staged
  • ❌ Photographer identity
  • ❌ Claim validity
  • ❌ AI content detection

Important: Rial provides technical verification only. Not a substitute for professional investigation, legal advice, or comprehensive review. Results should be part of a broader verification process.
