World, an identity verification project involving Sam Altman, is widening the reach of its human verification service starting with Tinder.

TechCrunch reported on April 17 that World plans to expand its verification technology into dating apps, performance and concert ticketing, enterprise services and email.

World was previously known as Worldcoin. It promotes a way to confirm, while preserving anonymity, that a living person is using a digital service. The core verification tool is a spherical device called an Orb. It reads a user's iris and converts it into a unique anonymous cryptographic identifier, which is used as a verified World ID. The World app can also be used without Orb verification.

In this expansion, the first area to be applied is dating apps. Tinder ran a World ID pilot programme in Japan last year and is expanding it to global markets including the United States. Users who complete verification will have a World ID badge added to their profiles.

It is also targeting the concert ticket market. World introduced a "Concert Kit" that lets artists allocate a set number of tickets to users verified with World ID. The feature aims to block scalpers who use automated buying bots. The service will integrate with major ticketing systems including Ticketmaster and Eventbrite, and 30 Seconds to Mars and Bruno Mars plan to use it on upcoming tours.

It also announced links to enterprise services. It will connect Zoom with World ID to address deepfake risks in video conferences, and it will work with DocuSign to verify that electronic signatures came from real users. World is also preparing an "agent delegation" feature that lets users delegate their World ID to an agent to carry out online activity on their behalf. With Okta, it built a beta system to verify that a specific agent is acting in place of a real person.

World is also strengthening scalability. Until now, Orb iris scans, the top level of verification, required users to visit sites in person, limiting adoption. It is therefore significantly increasing Orb deployments in New York, Los Angeles and San Francisco, and has also introduced a model that brings an Orb to a requested location.

It also broke verification into more tiers. The top tier is Orb verification, and below it is an intermediate tier that uses the NFC chip in a government-issued ID. It also added a low-tier verification called "Selfie Check" that relies only on a selfie. World said it is allowing developers to choose among the three verification tiers based on the required security level.

World's expansion is drawing attention as an attempt to apply layered human verification by service in an environment where AI and bots are increasing. It is also directly tied to improving scalability by maintaining an iris-scan-centred structure while extending verification steps to IDs and selfies.
