Hardware-signed photos via C2PA on mobile—solves real insurance and marketplace fraud detection.

Strengths
  • •Leverages Secure Enclave/TEE for cryptographic signing, eliminating cloud dependency for attestation.
  • •Cross-platform (iOS/Rust + Android) with zero-copy JPEG embedding and standard C2PA verification tools.
  • •Addresses concrete use cases (insurance damage claims, car/real estate listings) where deepfakes are a genuine liability.
Weaknesses
  • •Narrow audience: only valuable for apps already requiring photo provenance verification.
  • •Early stage with minimal adoption signal; success depends on C2PA ecosystem maturation and enterprise adoption.
Target Audience

Mobile app developers building marketplace, insurance, and KYC applications requiring photo provenance verification.

Post Description

Heey

With all the AI stuff that's happening now, checking the provenance of photos will be a reality sooner rather than later. C2PA is the standard for this. Leica and Sony already ship it in some cameras, but I couldn't find anything for mobile that didn't require a whole SDK. So I built it.

It's a React Native package. You take a photo with whatever camera lib you want, pass the path to signPhoto(), and it hashes the image, signs it with the device's Secure Enclave (iOS) or StrongBox/TEE (Android), and embeds a full C2PA manifest into the JPEG. The file that gets saved is already signed.

Where I think this actually matters: - insurance apps (prove damage photos are real) - marketplace listings (verified photos for cars/real estate) - field inspections, KYC selfies. Anywhere someone has an incentive to submit fake photos.

Would love feedback, especially from anyone who's worked with C2PA or hardware attestation on mobile.
