Privacy in the age of AI: Video explainer series

As highlighted in its privacy white paper, Worldcoin is built around four key privacy principles:

• Security: Secured by math
• Anonymity: Move freely online
• Transparency: Built in the open
• Choice & Control: Your data, your rules

These ideas inform all aspects of the Worldcoin project, from the hardware used to verify humanness and uniqueness to the cryptographic technologies used to ensure community members remain unidentifiable. 

In this series, you’ll learn more not only about these fundamental guiding principles and how they’re put into action, but about why they’re necessary in a world with rapidly advancing AI. 

As AI advances, its ability to mimic behaviors that foster trust between humans has the potential to disrupt our online interactions. 

TFH Chief Information Security Officer Adrian Ludwig and Head of World ID Ajay Patel discuss this challenge, and how proof of humanness can help. 

Proving you’re one unique human online shouldn’t mean you have to give up your anonymity. 

TFH Chief Privacy Officer Damien Kieran explains how privacy enhancing technologies are used to keep World ID holders anonymous. 

Worldcoin’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 Worldcoin ensures community members are informed about the project, their rights and how to get in contact.

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.

Secure multi-party computation, or SMPC, 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 original information. 

TFH Chief Information Security Officer Adrian Ludwig talks in plain terms about how SMPC works at Worldcoin and the critical role it plays in keeping potentially sensitive data secure. 

Worldcoin is committed to a user-centric design that allows for increased transparency and verifiability (more on this in the project whitepaper), and Personal Custody is a key component of that design.

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.

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 Worldcoin’s Face Auth different from facial recognition technologies used by other organizations.
