The future of online commerce increasingly depends on reliably distinguishing when a human or an AI agent is performing a transaction. Emerging "proof-of-human" technologies aim to allow a person to vouch that an AI agent acting on their behalf is linked to a specific real human.
World and iris-based verification
World, the startup co-founded by Sam Altman, builds a solution that verifies people by scanning their irises. The company this week announced new tools that let individuals link that proof of humanity directly to an AI agent.
Tiago Sada, World’s chief product officer, said this could eventually lead online sellers to offer perks to verified agents — for example, discounts or free trials. According to Sada, when merchants can be sure an agent originates from a human, they may be willing to be more generous in the terms they offer.
Why this matters
Proof-of-human approaches could allow websites to keep malicious bots off their platforms without imposing blanket bans on all automation. That matters in e-commerce, where agents do not only make purchases but can handle customer service and personalized offers.
Other industries remain cautious
Not every sector is ready to embrace agent-based transactions. Axios reported that several large U.S. banks are restricting interaction with third-party agents, in part because they cannot reliably determine which agents a customer actually authorized. This suggests financial services, with their higher security and compliance demands, may adopt such solutions more slowly.
Implications and outlook
If person-linked verification becomes widespread, it could change online business dynamics: merchants could selectively reward verified agents while platforms better filter out malicious automation. At the same time, restrictions in banking and other sensitive areas indicate adoption will vary by industry.
World’s announcement and the broader development of proof-of-human technologies show these tools are increasingly likely to shape how we differentiate humans from AI agents in online commerce.
