Lorrie Cranor's Research

For more information about current research projects, see the current projects list on the CUPS web site. the following is a list of projects I started prior to coming to CMU in December 2003.

The Platform for Privacy Preferences (P3P)
I have been working with the World Wide Web Consortium to develop version 1.1 of the Platform for Privacy Preferences Project (P3P), a standard way for web sites to express their privacy policies in a computer-readable format.
Privacy Bird and Privacy Finder
I designed a P3P web browser pluggin called Privacy Bird while at AT&T. It is now being maintained and extended by my students at CMU. We also deployed a P3P search engine called Privacy Finder.
I worked with several colleagues at AT&T to conduct an Analysis of Security Vulnerabilities in the Movie Production and Distribution Process.
Publius is a Web publishing system that is highly resistant to censorship and provides publishers with a high degree of anonymity. You can read about Publius in the O'Reilly book Peer-to-peer: Harnessing the Power of Disruptive Technologies. Publius also received an award from Index on Censorship for the Best Circumvention of Censorship
In 1997 my group at AT&T helped design the technical aspects of an electronic voting system trial for Costa Rica. The trial was originally planned for 1 Feb 1998, but was postponed indefinitely at the request of the government of Costa Rica. Declared-Strategy Voting is a novel group decision-making procedure in which preference is specified using voting strategies, thus allowing voters to cast ballots that are both effective and expressive. This project was the subject of my dissertation. Sensus is a security-conscious electronic polling system designed for conducting secure and private elections and surveys over the Internet. I developed a Sensus prototype as part of my master's research at Washington University. You can learn more about my voting-related projects by visiting my voting page.
