In a world where AI can generate realistic images in seconds, Faust founder and CEO, Kosuke July Hata, who goes by July, is building a new kind of camera — one that proves a photo was actually taken by a human, on a specific device, at a specific time and place.

Roc Camera is a compact, point-and-shoot–style device that embeds cryptographic proofs into every image it captures. “It’s a camera that takes verifiably real photos in the age of AI,” July says. “It can prove that the photo could have only been taken by this specific camera.” 

The camera works by signing sensor data at capture time using a private key embedded in the hardware. These signatures are bundled with the photo to enable later verification. We've covered a similar topic during our episode on verifiable media, and have an earlier blog post that explains how verifiable media fits into the larger vision for verifiability.
