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)

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