28 January 2014 The Tracking Protection Working Group has published two documents today. A Working Draft Tracking Preference Expression (DNT) . This specification defines the DNT request header field as an HTTP mechanism for expressing the user’s preference regarding tracking, an HTML DOM property to make that expression readable by scripts, and APIs that allow scripts to register site-specific exceptions granted by the user. It also defines mechanisms for sites to communicate whether and how they honor a received preference through use of the Tk response header field and well-known resources that provide a machine-readable tracking status. A Working Draft of Tracking Compliance and Scope . This specification defines the meaning of a Do Not Track (DNT) preference and sets out practices for websites to comply with this preference.

13 September 2013 The Tracking Protection Working Group has updated two Working Drafts: Tracking Preference Expression (DNT) . This specification defines the technical mechanisms for expressing a tracking preference via the DNT request header field in HTTP, via an HTML DOM property readable by embedded scripts, and via properties accessible to various user agent plug-in or extension APIs. It also defines mechanisms for sites to signal whether and how they honor this preference, both in the form of a machine-readable tracking status resource at a well-known location and via a "Tk" response header field, and a mechanism for allowing the user to approve exceptions to DNT as desired. Tracking Compliance and Scope . This specification defines the meaning of a Do Not Track (DNT) preference and sets out practices for websites to comply with this preference.

To address rising concerns about privacy on the Web, W3C publishes today two first drafts for standards that allow users to express preferences about online tracking: Tracking Preference Expression (DNT) , which defines mechanisms for users to express cross-site tracking preferences and for sites to indicate whether they honor these preferences. Tracking Compliance and Scope Specification , which defines the meaning of a "Do Not Track" preference and sets out practices for websites to comply with this preference. These documents are the early work of a broad set of stakeholders in the W3C Tracking Protection Working Group , including browser vendors, content providers, advertisers, search engines, and experts in policy, privacy, and consumer protection. W3C invites review of these early drafts, expected to become standards by mid-2012. Read the full press release and testimonials and learn more about Privacy .
