Do I Do What I Say?: Observed Versus Stated Privacy Preferences
نویسندگان
چکیده
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.

But for a subject to be researchable, or research based, it needs to be supported by reason, a kind of reason that have a public and universal character. On the other hand we need a c...
