Proof of Human: Verifying Identity in the Age of AI

We built Proof of Human, an app for proving that a person was present when content was made.
- A capture step with a liveness challenge
- A signed record of the device, the time and the content
- A portal for verifiers, and a hiring module
- Sealed on 17 October 2026, with all twelve of its checks passed: an app-level seal that shows the app works; no liveness or accuracy results have been measured yet
