A Work Item of the Privacy Community Group.
A popular business model for the web is to get attribution and payment for clicks, for instance ad clicks that result in purchases or sign-ups. Traditionally, such attribution has been facilitated by user or device identifying cookies sent in cross-site HTTP requests. However, the same technology can be and has been used for privacy invasive cross-site tracking of users.
The technology described in this draft specification is intended to allow for click attribution, such as ad click attribution, while disallowing arbitrary cross-site tracking.
