Abstract:
As the number of Location-Based Service (LBS) users grows steadily worldwide, the need for data protection and privacy-respecting methods and standards grows with it. There exists a big variety of privacy enhancing approaches by now. However, very few seem to have explored the impact of time on people's sense of privacy. In this work, we attempt to answer the question whether and to what degree privacy concerns with respect to location sharing are time-dependent or not. For this purpose, we designed and carried out 2 different user studies, a web survey and a 4-week long experimental study. Our analysis shows evidence towards an existing dependency between time and the users' willingness to share their location. Moreover, the effect appears to be highly user-specific and correlates with certain personal features, such as conviviality and the general personal view on privacy and data protection.
