Prove you're real. Stamp anything. Verify anyone. RealStamp is a human authenticity system — a cryptographic toolkit that lets you sign any piece of content with proof that a verified human attested it. Locked to your Face ID. Anchored on a public transparency log. Verifiable by anyone in seconds. HOW IT WORKS STAMP. Capture text, attach a photo, video, or file. RealStamp signs it inside the Secure Enclave on your iPhone, with a key that never leaves the chip. Every stamp anchors to Sigstore Rekor — a public, append-only transparency log. Patent pending. SCORE. A 0–100 Trust Score reflects how verifiable you are and your stamping track record — never whether you used AI. It's built from your verified identity (email, phone, social, ID), your stamping activity (volume and consistency over time), and the quality of your credentials (taking editorial responsibility, maintaining the C2PA chain, and keeping stamps active). Open disputes and revocations reduce your score. VERIFY. Anyone, with or without an account, can verify any RealStamp credential in seconds. Signature, anchor, score, and dispute status — all public, all auditable. WHAT'S INSIDE • Hardware-backed Face ID — every stamp signed by a key inside Secure Enclave. FIDO2 Level 3 equivalent. No password. No software fallback. • Sigstore Rekor anchoring — every credential written to a public transparency log. Cannot be backdated or forged. • SD-JWT credentials — selective disclosure. Show what you want, prove the rest. • Sign in with Apple supported — when you choose Apple's Hide My Email, your real address is never shared. • C2PA-compatible content credentials — built on the open C2PA standard for content provenance. WHO IT'S FOR Creators publishing original work. Journalists and witnesses in the field. Researchers and authors. Anyone who wants to be verifiable as human in a synthetic world. PRIVACY Signing happens inside the Secure Enclave on your device. Liveness frames are processed in real time and discarded — we do not store any biometric template or faceprint. Photos and videos you choose to attach to a stamp are stored so verifiers can see what was stamped; you can delete them at any time. We support Sign in with Apple, email with a 6-digit code, and device passkeys. REGULATORY Designed to meet EU AI Act Article 50 disclosure requirements. Patent pending (USPTO 64/045,301). FREE TO DOWNLOAD. FREE TO VERIFY OTHERS.

RealStamp is a human authenticity system that allows you to cryptographically sign digital content, proving it was attested by a verified human. It uses hardware security and a public transparency log for verifiability. ### How does RealStamp ensure authenticity? Each stamp is signed within your device's Secure Enclave using a hardware-backed key. Signatures are anchored to Sigstore Rekor, a public transparency log, making them tamper-proof and auditable. ### What is the Trust Score in RealStamp? The Trust Score is a metric from 0-100 that reflects your verifiability and stamping history. It considers your verified identity, stamping activity, and credential quality, not AI usage. ### Is RealStamp free to use? Yes, RealStamp is free to download and free to verify others' credentials. An account is only required if you wish to stamp your own content. ### Does RealStamp store biometric data? No, RealStamp processes liveness frames in real-time and discards them immediately. It does not store any biometric templates or faceprints. ### What devices does RealStamp support? RealStamp is available for iPhone and iPad devices, as indicated by its support for iOS and iPadOS. ### How often is RealStamp updated? The latest version, 2.1.2, was released on June 5, 2026, indicating active development and regular updates to the application. ### Is RealStamp suitable for all ages? RealStamp has an age rating of 4+, making it appropriate for a wide range of users, including children, though its primary utility is for adults. ## Version history (last 5 releases) ### 2.1.2 — 2026-06-05 Cleaner home screen and reliability improvements. ### 2.0.2 — 2026-05-19 What's new in this update: • Sign in with Apple now works reliably on iPhone • QR codes scanned with the iPhone Camera now open the verification page directly in the app • You can now stamp the same content more than once without errors • New floating + button on every screen for one-tap access to stamping • Clearer, more helpful error messages Thank you for using RealStamp. ### 2.0 — 2026-05-11 v2.0 — Hardware-Backed. Every stamp is now signed by Face ID against a key that lives inside your iPhone's Secure Enclave. FIDO2 Level 3 equivalent. No password. No software fallback. Your face is the key. WHAT CHANGED • HARDWARE-BACKED LIVENESS — Face ID + Secure Enclave signing keys. Replaces software liveness checks entirely. Defeats the first-hop human attack class. • SIGN IN WITH APPLE — First-party native auth. No third-party trackers. Apple hides your email by default. We never see it. • 9-SIGNAL TRUST VERDICT — Behavioral, device, velocity, content, liveness, social, chain, turnstile, attestation. Single aggregated trust score per stamp. Patent pending. • EU AI ACT ALIGNMENT — Updated content credential surface to meet EU AI Act Article 50 disclosure requirements. • C2PA INTEROP — Improved interoperability with Adobe, Microsoft, BBC, and other C2PA-compatible content credential systems. WHY IT MATTERS The next year will see the internet flooded with synthetic content. Watermarks fail. Detectors fail. The only thing that holds is cryptographic proof at the moment of creation, signed by a human inside hardware they alone control. That's RealStamp.
