Proceedings of the Ninth Symposium on Usable Privacy and Security

Welcome to the Ninth Symposium On Usable Privacy and Security! This year's program features 15 technical papers, three workshops, 25 posters, 5 posters/papers published in the past year at other conferences, a panel, two lightning talks and demo sessions, and an invited talk. On Thursday evening SOUPS 2013 attendees will enjoy a dinner at Alnwick Garden. This year we received 51 technical paper submissions. The program committee provided two rounds of reviews. In the first round papers received at least three reviews. In the second round, papers that had received one or more reviews better than "weak reject" in the first round received additional reviews. The goal of the second round was to ensure that a consistent standard of acceptance could be applied across all papers and, to this end, papers received as many as six reviews. We held an in-person program committee meeting. Fifteen papers were selected for presentation and publication.
