| I’ve been working on a tool to address one of the biggest problems I see with digital content: the inability to prove that it was captured by a real human, on a real device, at a specific time — without manipulation or AI involvement. Witness by Reel Human is a privacy-first camera app that generates cryptographically signed photos and videos. Each file includes an embedded JSON manifest with:
- The exact capture time
- Device info (not user identity)
- The app version and signature metadata The manifest is stored inside the media file (MP4/JPEG) and travels with it, even if shared. The result is a verifiable, human-authored piece of content. What’s working now (POC):
- Android and iOS apps (available for testing)
- Signed JSON manifests inside every photo/video
- No accounts, no tracking, no upload What’s coming:
- Public verification portal (in progress)
- Registry backend with optional verification logging
- Open API for platforms to verify content at scale I’d love your feedback on:
- The idea and approach
- Security model (crypto choices, manifest design, etc.)
- Use cases beyond journalism (legal, education, social media) Site: https://reel-human.com

iOS: Ask me anything — I’m solo-building this because I think trusted content should be a human right. |
