The Privacy Foundation conducts "research into communications technologies and services that may pose a threat to personal privacy." Its Web site has a large amount of information to raise awareness of privacy related issues and help the public understand them. For people wanting to learn some basic terminology in digital privacy, a glossary describes things like firewalls and cookies. There are detailed articles that answer many common questions about Web Bugs and suggest guidelines for how they should be used by companies. A large section of the site discusses workplace surveillance, and a legal database documents several important court cases.
