Sam Altman, CEO of OpenAI, has launched a new startup called World aimed at authenticating human identities online amid the rise of AI-generated content. The company plans to use biometric verification methods, including iris scans stored on blockchain technology, to enhance identity verification processes. This development follows earlier innovations such as Amazon One's palm reader at Whole Foods. Meanwhile, the identity verification and digital risk protection sectors are attracting substantial investment. Doppel, an AI-powered platform that protects organizations from social engineering threats like phishing and deepfake fraud, recently closed a $35 million Series B funding round. Duna, co-founded by former Stripe executives and backed by Index Ventures, raised €10.7 million to streamline business identity verification with AI, targeting the €50 billion market. Additionally, Persona, which assists companies including OpenAI, LinkedIn, and Reddit in verifying millions of users, secured $200 million in fresh funding from leading venture capital firms, reflecting growing investor confidence in solutions addressing identity challenges in the AI era.
