Introducing HumanSnap Combating Fake AI-Generated Images with Human Verification

HumanSnap is a described application that aims to prove an image was captured by a verified human rather than generated by AI. It uses Worldcoin's WorldID Proof of Humanity, which the article says verifies unique humans through a one-time biometric check such as iris scanning, to gate image capture. Each captured image is combined with its WorldID proof, signed with an RSA key pair generated via the Web Crypto API, and bundled into a downloadable proof_bundle.json file that external parties can use to verify the signature.
