IPA is a Private Measurement proposal for the W3C's Private Advertising Technology Community Group (PATCG.).
IPA End to End is our latest version of the proposal.
We also have a formal analysis posted on ePrint.
We are actively prototyping an implementation.
The PATCG hosts meetings on a roughly bi-monthly basis. Anyone can sign up to join the community group and join these meetings.
The IPA team also hosts an IPA focused bi-weekly VC call to discuss open issues and progress.
We also have open research questions in the issues on this repo.
Our original draft, published in January 2022, is available here.
