According to CNBC, the biometric authentication project World, co-founded by OpenAI CEO Sam Altman, will launch in London this Thursday and plans to expand to major UK cities such as Manchester, Birmingham, Cardiff, Belfast, and Glasgow in the coming months. World scans human eyes using a spherical device called Orb to generate unique iris codes to verify whether the user is human, aiming to address the risks of AI misuse such as deepfakes.
