You think you are browsing anonymously, checking airfares to Elbonia. Suddenly you get emails advertising Elbonian attractions. How do these companies know your email address when you never identified yourself to the airplane site? There are many ways, and largely undocumented. We’d like to harness the collective wisdom in the room to collect pathways.
Learning Objectives: 1: Document current pathways for personal information leakage. 2: Brainstorm technologies to block these pathways. 3: Brainstorm pros and cons of information collection to users.
