About Precog is a group of researchers who study, analyze, build, and evaluate security and privacy aspects of complex networked systems (e.g. social web systems like Twitter, Facebook, and telephone call details). By understanding and characterizing user perceptions of security and privacy, we are interested in building secure usable technologies. Our work derives techniques from Computer Science, Information Technology, Data Mining, Text Mining, Statistics, Social Science, Public Policy, Human Computer Interaction, and Psychology. Below is a tag cloud of the words that we dabble with.
