Web servers and the entities that operate them have long had the
ability to track user agents as they access resources hosted across
different web domains. Concern over the privacy implications of such
tracking has prompted recent work on a number of solutions that aim
to provide a universal opt-out mechanism for web tracking that can be
effectuated through a simple binary choice presented to users.
This document provides an overview of the following mechanisms:
permanent opt-out cookies, cookie blocking, domain blocking, a "Do
Not Track" (DNT) HTTP header, and a Do Not Track Document Object
Model (DOM) property. The aim of this document is to describe each
approach, the pros and cons of each, and areas where standardization
may be necessary should each approach be further pursued, without
making recommendations about which approach or approaches should be
adopted.
