Learn more about World’s fundamental guiding principles, how they’re put into action and about why they’re necessary as AI rapidly advances.

Video explainers

Preserving anonymity

Proving you’re one unique human online shouldn’t mean you have to give up your anonymity. In this video, TFH Chief Privacy Officer Damien Kieran explains how privacy enhancing technologies are used to keep World ID holders anonymous.

Face Auth

Face Auth is a completely private 1:1 face comparison that ensures only the person who verified their World ID at an Orb can use it. TFH Head of AI Chris Brendel discusses how this technology works and what makes World’s Deep Face different from facial recognition technologies used by other organizations.

Trust in online interactions

As AI advances, its ability to mimic behaviors that foster trust between humans has the potential to disrupt our online interactions. In this video, TFH Chief Information Security Officer Adrian Ludwig and Head of World ID Ajay Patel discuss this challenge, and how proof of human can help.

Consent, education and information

World’s compliance with data protection regulations globally starts with a comprehensive security and privacy program. TFH Chief Privacy Officer Damien Kieran walks through some of the many ways World ensures community members are informed about the project, their rights and how to get in contact.

Zero-knowledge proofs

Zero-knowledge proofs, or ZKPs, are a cryptographic way for one party (the prover) to prove to another party (the verifier) that they possess knowledge without revealing what the underlying information actually is. TFH Chief Information Security Officer Adrian Ludwig breaks down this important technology into simple, easy to understand terms and describes how it’s used to protect World ID holders.

AMPC

Anonymized Multi-Party Computation, or AMPC, is a field of cryptography that encrypts potentially sensitive information into multiple different “secret shares” that are held by multiple trusted parties. This way, no one party has access to the sensitive information. In this video, TFH Chief Information Security Officer Adrian Ludwig talks in plain terms about how AMPC works at World and the critical role it plays in keeping potentially sensitive data secure.

Personal Custody

World is committed to a user-centric design that allows for increased transparency and verifiability (more on this in World Whitepaper), and Personal Custody is a key component of that design. In this video, TFH Head of AI Chris Brendel discusses how Personal Custody works, and how it gives individuals control over the flow and management of their personal information.
