A social photography app where every photograph is signed at publication, stamped with the moment of capture, and checkable byte for byte. No filters. No AI. No algorithms engineered to keep you scrolling.
PROVENANCE BY ARCHITECTURE.
iPhone · iOS 15.5+ · Free
For fifteen years, social photography became a performance. Filters replaced light. Algorithms replaced curation. Generative AI began producing images no camera ever took.
We built Humana for the moment when you stop trusting what you see on a screen. Every photograph in Humana carries a cryptographic signature. A C2PA manifest issued the moment you publish, with the instant of capture written into it. A SHA-256 of the signed file, published beside the photograph for anyone to recompute. Not as a watermark — as a record you can check.
There is no gallery upload. No second chances. The camera opens. You see. You capture. You publish. What appears in Humana is what existed in front of your lens, the instant you decided it was worth keeping.
This is the proof.
Each photograph in Humana passes through three layers that record where it came from. Tampering with any one breaks the chain, and the break is visible.
A custom iOS camera built from scratch. No gallery upload. No post-processing. The photograph goes from the sensor straight into the post, and the shutter instant travels with it — that instant is what the signature will declare. Camera metadata is stripped.
Server-side, every photograph is signed using C2PA — the Content Authenticity standard backed by Adobe, Microsoft, BBC and Sony. ECDSA P-256, with the key held in Google Secret Manager. The manifest declares a camera capture and its time, and the SHA-256 of the signed file is published with it. Tampering breaks the seal.
Every post has a public record, accessible by QR code. Anyone — Humana user or not — can open it from any browser, download the file and recompute its SHA-256 against the one published there. The signature accounts for the origin of the file. The identity of the signer is verified inside Humana.
A chronological feed — never engagement bait. No infinite scroll designed to consume your evening. No notifications engineered to drag you back.
Every photograph in Humana has a public record page. A QR code opens it — accessible to anyone, without an account, without an app.
The same standard adopted by The New York Times, BBC News and Adobe Photoshop. Open. Auditable. Edit one byte and the manifest stops validating.
On the App Store. iPhone, iOS 15.5 or later. Free.
