Completely private. Forever.
We don’t want to know who you are,
just that you are unique.
The Orb checks that you are a real human and that you have not signed up before. It does this by capturing and processing images of you and your unique iris pattern.
Since no two people have the same iris pattern and these patterns are very hard to fake, the Orb can accurately tell you apart from everyone else without having to collect any other information about you — not even your name.
Your choices are:
Images data never leaves the Orb. Once you’ve verified, it’s permanently deleted.
The images taken by the Orb are first processed locally on the Orb and then permanently deleted. The only data that remains is a message containing your iris code. This iris code is a set of numbers generated by the Orb and is not linked to your wallet or your World App account . As a result, it really tells us — and everyone else — nothing about you. All it does is stop you from being able to sign up again.
Since you are not required to provide personal information like your name, email address, physical address or phone number, this means that you can easily sign up without us ever knowing anything about you.
Here you can see what happens to your data when you sign-up with the Orb:
We don’t want your name, email, passport, or a selfie.
Your Worldcoin App is your self-custodial wallet. That means, just like a physical wallet, that no banks, governments or corporations can do anything to it — like lose or freeze your money — you’re in complete control.
World ID Privacy
Prove that you are a real and unique person, without revealing who you are.
Once you have a World ID, you can use it to prove that you are a real and unique person without revealing who you are. Importantly, developers — including us — cannot see what you have used your World ID for in the past; they can just see what you are trying to use it for when you use it.
This is made possible by Zero-Knowledge Proofs, which prove both that your World ID is real and that you have never done the action you are trying to do before, without revealing who you are.
