The first verification that proves a real human made it — through all the AI.
The internet lost the ability to tell who made anything. 5arz gives it back. Verify yourself once, then sign your photos, video, writing, and work with a tamper-evident Verified-Human badge anyone can check — against public keys, trusting no one.
Free for people. Not KYC. Not a government-ID check. No biometric data ever leaves your device or is stored.
AI can make anything. Nobody can prove a human made it.
Photos, video, voice, and writing are now generated at zero cost, indistinguishable from human work. Detection tools guess from artifacts in the pixels — and every guess gets weaker as the models get better. Guessing is a losing game. So we stopped guessing and started signing.
Creators
Your work gets scraped, cloned, and drowned in AI slop — and your face and voice get faked. Prove what's really yours.
Platforms & advertisers
Half the internet is bots. Reward real human creators and audiences instead of synthetic supply.
AI labs & agents
Provably human-made data and human-authored work — a distinguishable, certifiable asset as the web fills with synthetic content.
Three steps. Verifiable by anyone.
We publish what we cover, never how — the verification method is proprietary and patent-pending. That protection is the point: others can claim provenance, but they can't reproduce ours.
Verify you're human
Prove once that you're a real, unique person. No name or biometric is stored — only an anonymized reference that says "a genuine, verified human," never who.
Sign your content
Your credential is bound to you and to the exact file. Copy the badge onto different content and it fails — the proof is tied to those exact bytes and no other.
Anyone verifies it
The badge links to a public proof anyone can check offline against 5arz's public keys — no 5arz software, no account, no trust in us required. It fails closed.
Born-verified capture
Shoot a photo, video, or voice note inside the 5arz app and it's signed the instant it's created — proving both authorship (a verified human made it) and originality (signed at the moment of creation, not lifted from somewhere else). The proof travels with the file everywhere.
Works with C2PA
C2PA proves which camera captured a file and how it was edited. It leaves one question open — was a real human the author? 5arz adds exactly that claim, inside C2PA's own container, so existing authenticity tools recognize it. We extend the standard; we don't replace it.
One badge. Provably human.
Put it on your posts, your profile, your portfolio, your work. Your audience clicks it and confirms a real human made this — independently, against public keys.
It proves a verified human authored the file. It does not claim the content is true, complete, or unedited after signing. A proof of human origin — not a fact-check, not a seal of approval.
Everyone who needs to prove they're real.
People
Own a portable proof you're a real human — for profiles, marketplaces, dating, anywhere bots pretend to be people.
Creators
Mark your work human-made, defend against impersonation and deepfakes, and stand out from AI slop.
Platforms
Show native "verified human" marks on posts and profiles. Reward real creators and real audiences.
AI & agents
Prove the human behind the work — human-authored data and the human leg of agentic commerce.
The honest answers.
Is this KYC or a government ID check?
No. It's proof of personhood and human-made provenance — that a real, unique human is behind the content. It is not a KYC or government-identity verification, and makes no claim beyond human authorship.
Do you store my face or personal data?
No. No raw biometric data leaves your device, and no personal data is stored in the credential. We keep only a fingerprint of the content and the signed credential — never the content itself, and never your identity. There's no honeypot to breach.
Can the badge be copied onto AI content to fake it?
No. Each credential is bound to the exact bytes of the file it was issued for. Copy the badge onto a different file and the fingerprint no longer matches, so verification fails. A forged credential also fails signature verification against our public keys.
Does the badge prove the content is true?
No. It proves a verified human authored the file. It makes no claim that the content is true, accurate, high-quality, or unedited after signing. It's a proof of human origin, not a fact-check.
What if a platform strips the metadata?
The proof still resolves. A visible badge links to a public verification page, and the content can be re-matched by its fingerprint even when embedded metadata is removed on upload.
Can someone copy your code and forge proofs?
No. Trust lives in a private signing key that never leaves our infrastructure, plus the network of verified humans and a patented method — not in the code. Anyone can verify; only 5arz can issue. Cloning the client forges nothing.
Prove you're human. Prove you made it.
Free to verify. Yours to own. The affirmative proof-of-human layer for the age of AI.
