The “free” Web is powered by a multi-billion dollar online advertising industry. Advertisers track users across the Web to show them targeted advertisements. Professor Shafiq will discuss the scope of online tracking, including its implications on user privacy and government surveillance. He will also discuss current UI research on increasing transparency to empower users to limit online tracking.
