Tinder is partnering with World, Sam Altman's iris-scanning verification company, to let users prove they're human and combat AI bot profiles by getting a 'proof of humanity' badge. The feature works through World's app or orb-shaped devices that scan users' irises, and Tinder previously piloted it in Japan before the global rollout. World is simultaneously expanding partnerships with Zoom, DocuSign, Shopify, and Reddit, pushing biometric verification as a solution to AI impersonation across multiple platforms. The rollout raises privacy concerns, though details about data storage and use beyond initial verification remain sparse in the coverage.
