Privacy Activity

The evolution of Web technologies has increased collection, processing and publication of personal data. Privacy concerns are raised more often as applications built on the Web platform have access to more sensitive data — including location, health and social network information — and users' activity on the Web is ubiquitously tracked. The W3C Privacy Activity coordinates standardization work to improve support for user privacy on the Web and develops general expertise in privacy-by-design for Web standards.

Privacy Interest Group

The group monitors ongoing privacy issues that affect the Web, investigates potential areas for new privacy work, and provides guidelines and advice for addressing privacy in standards development.

Christine Runnegar (Internet Society) and Tara Whalen (Google) are co-chairing the group. Keiji Takeda (W3C) is the Team Contact.

Want to learn more? Please join the group and the mailing list. (Non-Members may join the group as public Invited Experts.)
