"Malicious actors have been exploiting anonymity as a way to deceive others online," explained Shrey Jain, a Microsoft product manager, in a Microsoft Research podcast interview.
"Historically, deception has been viewed as this unfortunate but necessary cost as a way to preserve the internet's commitment to privacy and unrestricted access to information.
"Today, AI is changing the way we should think about malicious actors' ability to be successful in those attacks. It makes it easier to create content that is indistinguishable from human-created content, and it is possible to do so in a way that is only getting cheaper and more accessible.
The answer Microsoft, OpenAI, and various academic researchers propose is personhood credentials - or PHCs - which are essentially cryptographically authenticated identifiers bestowed by some authority on those deemed to be legitimate people.
