Tinder will let users prove they are human by bringing advanced eye-scanning technology to the app amid rising fears over AI. Users of Tinder and other major platforms such as Zoom can now scan their irises to earn a 'proof of humanity' badge attached to their profile or name.

World, formerly known as Worldcoin, is part of Tools for Humanity, a start-up co-founded and chaired by Sam Altman who is also the head of ChatGPT-maker OpenAI. Once a person is confirmed as human by the technology they receive a unique identification code which is stored on their smartphone and considered their World ID.

A new World ID app, as well as the partnerships with Tinder and Zoom, were revealed during a live event in San Francisco on Friday. It began with a video projected on several large screens in a small auditorium depicting several famous journalists, including Walter Cronkite, Dan Rather, and Larry King, as well as former President Ronald Regan.

All of the men were shown using historic video footage that had been altered using AI to have them appear to be realistically discussing the need for a way to identify who is human on the internet. Altman took the stage briefly after the deepfake montage to applause from an audience of a few hundred people. He said there will soon be 'more stuff made by AI than is made by humans' online.

Tinder and Zoom have encountered more problems with fake or malicious accounts over the last two years as improving AI technology has made it easier to impersonate human speech, voice and likeness. Fake profiles on Tinder are typically used to scam people out of money or their personal information. Late last year, Tinder began requiring all users to submit a video selfie to confirm they were real people.
