The venture, which uses a spherical eye-scanning device called the Orb to scan people’s eyes, will become available in London from Thursday and is planning to roll out to several other major U.K. cities — including Manchester, Birmingham, Cardiff, Belfast, and Glasgow — in the coming months. The project aims to authenticate the identity of humans with its Orb device and prevent the fraudulent abuse of artificial intelligence systems like deep fakes. It works by scanning a person’s face and iris and then creating a unique code to verify that the individual is a human and not an AI. Once someone has created their iris code, they are then gifted some of World’s WLD cryptocurrency and can use an anonymous identifier called World ID to sign into various applications. It currently works with the likes of Minecraft, Reddit and Discord.
