Origin Lens – Verify Image Authenticity with C2PA Content Credentials

arXiv

Combat fake news and misinformation by verifying the authenticity of images with cryptographic provenance data.

Origin Lens analyzes images for C2PA (Coalition for Content Provenance and Authenticity) Content Credentials, EXIF metadata and SynthID to detect AI-generated content, verify digital signatures, and reveal the complete edit history of any image. Core verification happens on your device. An optional reverse image search feature uses external services to help detect out-of-context images.

✨ What Makes Origin Lens Different?

Origin Lens goes beyond simple metadata viewing. It performs cryptographic verification of Content Credentials, detects AI-generated content from multiple sources, and provides comprehensive provenance analysis. All verification happens locally on your device.

C2PA Content Credentials Verification

Cryptographically verify the authenticity of images.

  • Digital signature validation – Verify cryptographic signatures on embedded C2PA manifests
  • Certificate chain verification – Check if signers are trusted and certificates are valid
  • Tamper detection – Identify if content has been modified since signing
  • Signer information – View organization, issuer, and timestamp details
  • Multiple verification states – Verified, Invalid Signature, Expired Certificate, Untrusted, or No Manifest

🤖 AI Generation Detection

Identify AI-generated content from multiple sources.

  • C2PA assertions analysis – Detect AI generators from standard Content Credentials
  • EXIF metadata parsing – Find AI signatures in image metadata
  • Multi-source detection – Combines C2PA, EXIF, and SynthID for comprehensive coverage
  • 50+ AI generators detected – Midjourney, DALL-E, Stable Diffusion, Adobe Firefly, and more
  • Detection source transparency – Shows whether AI was detected via C2PA, EXIF, or SynthID

📜 Complete Edit History Timeline

See every action performed on an image.

  • Action-by-action timeline – View capture, edit, and publish events
  • Software agent tracking – Identify tools used to create and modify content
  • Timestamp information – When each action occurred
  • Digital source type – Understand the origin (camera capture, screen capture, AI generation, etc.)

EXIF Metadata Analysis

Access detailed image metadata.

  • Camera information – Make, model, and settings
  • Software details – Applications used to create or edit the image
  • Artist and copyright – Creator attribution
  • Date and time – When the photo was taken
  • AI detection markers – Prompt parameters, generation settings, and AI tool signatures

🔎 Reverse Image Search (Optional)

Find where images have appeared online.

  • Multi-engine search – Searches across Bing, Yandex, and Google
  • Context verification – Detect out-of-context or misattributed images
  • Smart filtering – Removes irrelevant results like login pages
  • Privacy notice – Clear warning before uploading to external services
  • Bring your own keys – Use your own API keys for enhanced privacy

Note: This optional feature uploads images to external search services. A clear privacy note is shown before use.

📤 Multiple Input Sources

Analyze images from anywhere.

  • Photo Library – Select from your gallery
  • Files App – Access iCloud Drive and local files
  • URL Analysis – Paste image URLs for remote verification

📱 Key Features

🔍 Image Analysis

Select images from your photo library, files, or paste a URL to analyze any image for Content Credentials and metadata.

✅ Verification Status

Clear visual indicators show whether content is verified, has signature issues, expired certificates, or no C2PA data.

🤖 AI Detection Badge

Prominently displays when content is detected as AI-generated, showing the generator name and detection method.

📊 Detailed Provenance Information

View signer details, complete edit history, EXIF metadata, and raw manifest data all in one comprehensive interface.

🌐 URL Support

Analyze images directly from the web without downloading them first.


🔒 Privacy You Can Trust

Core verification happens on your device. Optional features use external services with clear disclosure.

  • On-device verification – All C2PA and EXIF analysis runs locally
  • Zero data collection – No analytics, no tracking, no servers
  • No account required – Works immediately after install
  • Transparent remote features – Reverse image search clearly warns before uploading
  • Bring your own API keys – Use personal keys for external services
  • Privacy first – Read our Privacy Policy
