11:15	Invited Speaker: Jennifer Granick (Bio), "Privacy Hot Spots: A Call to Action."
	Abstract: Protests in Iran are organized over Twitter and Facebook. Chinese citizens confront mandatory installation of filtering software. U.S. Border Agents have plenary authority to seize laptops and phones entering the country. Mobile phones constantly report their location to the cellular network. These are some of today's hot spots where legal action is inadequate to protect people's privacy. Technological solutions are needed, and this is a call to action for scientists, researchers and coders. However, the technological solutions may not be something new and different, but rather something familiar and simple. Proxy servers, default https and privacy-friendly data retention practices may have the most privacy-friendly effects.

11:00	Invited Speaker: Alessandro Acquisti (Bio), "Of frogs and herds: Behavioral Economics, Malleable Privacy Valuations, and Context-dependent Willingness to Divulge Personal Information."
	Abstract: I will present a number of experiments investigating privacy valuations and decision making through the lenses of behavioral economics. Contrary to the assumption in much social science that people have stable, coherent preferences with respect to personal privacy, we find that privacy valuations (measured by willingness to trade-off personal information for monetary rewards) and concerns about privacy measured by divulgence of private information) are highly sensitive to contextual factors. We report results from a number of experiments, one of which was designed to measure individual willingness to pay to protect and willingness to accept to divulge personal data; while others were designed to elicit or to suppress privacy concerns. This research raises questions about whether individuals are able to navigate in a self-interested fashion increasingly complex issues of privacy.

5:30	Film Screening: "We Live in Public" directed by Ondi Timoner (More Info)
	Abstract: Ondi Timoner is the first and only two time Grand Jury Prize winner in Sundance history, and her latest-winning film is called We Live In Public, the story of the Internet’s revolutionary impact on human interaction as told through the eyes of internet pioneer and visionary Josh Harris. As far back as the early 90s, Harris predicted a future dominated by life online and created the companies that were direct predecessors to MySpace, Facebook and YouTube. The tale turns ugly when his underground NYC bunker housing dozens of permanent “citizens” and outfitted with hundreds of surveillance cameras is busted by FEMA as a millennial cult — Harris decides to take the experiment a step further and in doing so becomes a media casualty.
