"Privacy, Security, and Online Disclosures: Combining HCI and Behavioral Science to Design Visceral Cues for Detection of Online Threats"

(Vortrag im Rahmen der "MPI Distinguished Lecture Series" in Kooperation mit dem Fachbereich Informatik)

Online privacy and security decision making is complex, because it is affected both by objective risks and benefits from disclosure or protection of personal information, and by factors that do not directly affect economic trade-offs. For instance, design features - such as default visibility settings, look &l; feel of a website, granularity of privacy controls, or framing of privacy policies - as well as cognitive and behavioral biases affect risk perception. Behavioral sciences provide useful insights on how people respond to risks and threats. Of particular interest to my research is whether individuals detect, recognize, and react differently to "offline" and "online" threats. I will present a series of laboratory experiments, that combine findings from HCI and behavioral sciences, showing how to help users of online sharing technologies detect online privacy and security threats, and thus make better informed decisions. The experiments demonstrate how sensorial, visceral stimuli from the offline, physical world can affect online privacy concern and online disclosures. The results show the importance of going beyond privacy and security usability research, and provide suggestions on how to improve interfaces to help users make sound privacy and security decisions.
