Dear OAuth WG,

I'm Jian Wang, one of the authors of the following individual Internet-Draft, 
and we would like to invite feedback from the WG:
draft-li-oauth-policy-based-anonymous-tokens-00
Policy-Based Anonymous Tokens
Draft:
https://datatracker.ietf.org/doc/draft-li-oauth-policy-based-anonymous-tokens/

The draft explores a privacy-preserving authorization approach in which a 
resource server can verify whether an access request satisfies predefined 
authorization policies, while minimizing unnecessary disclosure of user 
identity information and reducing cross-service correlation.
The work is motivated by emerging scenarios such as AI agent interactions, 
distributed services, and cross-domain data sharing, where authorization 
decisions may still be required without exposing more identity information than 
necessary.

We would particularly appreciate feedback on:

  *   how the proposed approach relates to or could complement existing OAuth 
mechanisms and ongoing work;
  *   relevant specifications or prior discussions that we should take into 
account;
  *   the authorization model and policy representation proposed in the draft; 
and
  *   additional use cases or requirements that should be considered as the 
work evolves.

We would be happy to discuss the proposal further with the WG and refine the 
draft based on community feedback. If useful, we would also be glad to present 
the work at a future WG meeting.
Thank you in advance for your comments and suggestions.

Best regards,
Jian Wang
on behalf of the authors
