Lorrie Faith Cranor is a Professor of Computer Science and of Engineering and Public Policy at Carnegie Mellon University where she is director of the CyLab Usable Privacy and Security Laboratory (CUPS) and co-director of the MSIT-Privacy Engineering masters program. In 2016 she served as Chief Technologist at the US Federal Trade Commission, working in the office of Chairwoman Ramirez. She is also a co-founder of Wombat Security Technologies, Inc, a security awareness training company. She has authored over 150 research papers on online privacy, usable security, and other topics. She has played a key role in building the usable privacy and security research community, having co-edited the seminal book Security and Usability (O'Reilly 2005) and founded the Symposium On Usable Privacy and Security (SOUPS). She also chaired the Platform for Privacy Preferences Project (P3P) Specification Working Group at the W3C and authored the book Web Privacy with P3P (O'Reilly 2002). She has served on a number of boards, including the Electronic Frontier FoundationBoard of Directors, and on the editorial boards of several journals. In her younger days she was honored as one of the top 100 innovators 35 or younger by Technology Review magazine. More recently she was named an ACM Fellow for her contributions to usable privacy and security research and education, and an IEEE Fellow for her contributions to privacy engineering. She was previously a researcher at AT&T-Labs Research and taught in the Stern School of Business at New York University. She holds a doctorate in Engineering and Policy from Washington University in St. Louis. In 2012-13 she spent her sabbatical as a fellow in the Frank-Ratchye STUDIO for Creative Inquiry at Carnegie Mellon University where she worked on fiber arts projects that combined her interests in privacy and security, quilting, computers, and technology. She practices yoga, plays soccer, and runs after her three children.

Education

  • B.S. (Engineering and Public Policy) 1992, Washington University in St. Louis
  • M.S. (Technology and Human Affairs) 1993, Washington University in St. Louis
  • M.S. (Computer Science) 1996, Washington University in St. Louis M
  • D.Sc. (Engineering and Policy) 1996, Washington University in St. Louis

Research

My research focuses on usable privacy and security. My current projects fall into several overlapping areas: privacy decision making (including applications of P3P), user-controllable security and privacy (including location-sharing privacy and file access control in the home), and usable cyber trust indicators, and and usable and secure passwords. Prior to coming to CMU I did research on P3P, electronic voting, security vulnerabilities in the movie production and distribution proces, and other topics.
