Post TPAC Update #22

Closed benjaminsavage closed 1 month ago

benjaminsavage commented 1 month ago

At TPAC, we discussed a few changes to this spec:

  1. Using "filterData" instead of enumerating a list of ad identifiers. For now, the proposal was to use the simplest approach of a single integer.
  2. Storing information in the impression store about the script which invoked the saveImpression API, which might be a 3rd party script, and might be within an iframe. This could later be used for impression filtering and in the future, as a breakdown key.
  3. Providing the maximum conversion value to the device in the saveImpression call as it will be used to deduct appropriate privacy budget loss.
