Confirm user’s real
Detects that a real, live person, not a photo, mask, screen or video is completing the verification.
Selfie Check
Prove that the user is a real human, privately and anonymously.
A better way to prove you're human
With a quick selfie inside World ID App*, users can anonymously prove they’re a real human and provide a medium-assurance uniqueness signal, without revealing their identity or sharing their biometric information.
*Selfie Check is currently available in Beta and for selected partner apps.
What Selfie Check does

Helps partner apps understand whether the same person has already been seen, using a privacy-preserving medium-assurance risk signal.

Testimonials
For Olena, Selfie Check gives us a globally available way to reduce bots and Sybil attacks while keeping the sign-up experience simple. The selfie-based verification flow is simple and intuitive. Compared with other liveness checks we have seen, it feels much easier for users to complete while still giving us the level of assurance we need.
Suraj Kohli
CTO, Olena Protocol
Selfie Check gives us a lightweight way to verify a unique human before issuing a trial claim. In Agent Trials, before someone can claim the Valiron Pro trial, they complete World ID verification. We then bind that verification to the specific trial claim, which helps reduce repeated claims from throwaway accounts or automated abuse.

Privacy by design
Selfie Check was designed so the user's personal data never leaves their device.
Partners receive only proof
The image stays on the device and the World ID App, never shared with partner apps or anyone else. Apps receive only anonymous proof and medium-assurance uniqueness signal.
Anonymous uniqueness
The liveness check runs locally on the user's device. Anonymized Multi-Party Computation (AMPC) enables uniqueness checks while keeping all biometric information private and anonymous.
Open source technology
World is designed to operate as an open-source hardware and software and auditable infrastructure layer, subject to rigorous external scrutiny.
