Daniel Weitzner is Director of the World Wide Web Consortium's Technology and Society activities. As such, he is responsible for development of technology standards that enable the web to address social, legal, and public policy concerns such as privacy, free speech, security, protection of minors, authentication, intellectual property and identification. Weitzner holds an appointment as Principle Research Scientist at MIT's Computer Science and Artificial Intelligence Laboratory and teaches Internet public policy at MIT.

As one of the leading figures in the Internet public policy community, he was the first to advocate user control technologies such as content filtering and rating to protect children and avoid government censorship of the Intenet. These arguments played a critical role in the 1997 US Supreme Court case, Reno v. ACLU, awarding the highest free speech protections to the Internet. He successfully advocated for adoption of amendments to the Electronic Communications Privacy Act creating new privacy protections for online transactional information such as Web site access logs.

Before joining the W3C, Mr. Weitzner was co-founder and Deputy Director of the Center for Democracy and Technology, a leading Internet civil liberties organization in Washington, DC. He was also Deputy Policy Director of the Electronic Frontier Foundation. Mr. Weitzner has a degree in law from Buffalo Law School, and a B.A. in Philosophy from Swarthmore College.

His publications on communications policy have appeared in the Yale Law Review, Global Networks, MIT Press, Computerworld, Wired Magazine, Social Research, Electronic Networking: Research, Applications & Policy, and The Whole Earth Review. He is also a commentator for NPR's Marketplace Radio.
