W3C today published the report from the W3C Workshop on Do Not Track and Beyond held at UC Berkeley in November 2012. We welcomed experts from academia, industry, civil society and regulators to discuss the status of the current work of the Tracking Protection Working Group on Do Not Track, as well as related and future standards initiatives.

The Workshop reaffirmed the foundational assumption of a co-operative approach between the different stakeholders and identified a number of widely-shared views. We encourage those interested in ongoing work in this area to refer to the Tracking Protection Working Group, the Privacy Interest Group and the Customer Experience Digital Data Community Group.

W3C thanks the participants and appreciates the support of the UC Berkeley TRUST Science and Technology Center for hosting and of Yahoo! for sponsoring the event. Learn more about the W3C Privacy Activity.
