Web Tracking Protection Submission Request to W3C

Submitted Materials

We, W3C Member:

hereby submit to the Consortium the following specification, comprising the following document attached hereto:

which is referred to as "the Submission". We request the Submission be known as the Web Tracking Protection Submission.


The Web Tracking Protection specification is designed to enable users to opt-out of online tracking. The platform has two parts:

Together these technologies can be used to enforce privacy protection for users, and provide access to content and services that respect user privacy preferences.

A filter list contains parts of third-party URIs that a browser may access automatically when referenced within a web page that a user deliberately visits. Rules in a filter list may change the way the user agent handles third-party content. By limiting the calls to these websites and blocking resources from other web pages, the filter list limits the information other sites can collect about a user.

The Do Not Track user preference is a setting maintained by the user agent. It can be read by a webserver or client JavaScript. A webserver that respects the Do Not Track user preference will read this value and will not track the user when this setting is enabled.

Suggested action
