Do I Do What I Say?: Observed Versus Stated Privacy Preferences

Abstract. This paper examines the use of surveys in measuring privacy concerns in ubiquitous computing environments. Two evaluation techniques are used to study the privacy concerns of sharing context information: a paper based survey and in-situ questionnaires. Results from the two techniques differ significantly, suggesting that surveys are not reliable in predicting privacy concerns regarding context-aware services. Further, the surveys are not consistently biased; for some information, people shared more in-situ than they predicted they would share in the survey, while for other types, they shared less.
