Tinder, DocuSign, and Zoom all adopting eyeball scans identity to combat AI fraud, integrating Sam Altman’s 
World ID verification system to assure that users are actually human.
What's the Scoop?
- PoH Goes Mainstream: Tinder, DocuSign, and Zoom are integrating Sam Altman's World ID, a biometric identity system that verifies unique users via iris scans and issues a unique “proof-of-humanity” identifier. Tinder will offer World ID alongside existing video selfie verification, DocuSign will use the credential to ensure all parties to a contract are human, and Zoom users can display verified identity credentials to combat impersonation in calls.
- New Application: A new World ID app – World ID 4.0 – will function as a portable authenticator, allowing users to manage credentials, verify with third-party platforms, and control how their World ID is used across the internet.
- Expansive Reach: Built by Sam Altman-backed Tools for Humanity, World (formerly Worldcoin) touts 40M application users, including nearly 18M verified humans spanning six continents.
- Black Market Concerns: In 2023, reports first surfaced of a burgeoning black market for World IDs, with credentials sourced from users in developing nations like Cambodia and Kenya. The existence of such secondary markets risks undermining the integrity of the World IDs.
