This work aims at understanding behavior around location information, including why users share such information, why they protect the data, and what kind of other factors influence the decision to behave in a certain way. This book explores privacy in the context of location data, and answers questions such as what are the privacy related behaviors in this context, and what are the factors influencing such behaviors. The book gives an overview to what privacy means for users in terms of understandings, attitudes and valuations. This book discusses reasons for why research around this topic is challenging, and presents various methods for diving into the topic through empirical studies. The work is relevant for professionals, researchers, and users of technology.

• Presents an in-depth overview of perceived privacy in the context of location-based services
• Extends beyond hypothetical assessment of behavior by analyzing user behavior in long field studies

• Includes qualitative interviews, field studies, and data collected using different types of location-based application

  Autorentext
  Maija Poikela received her PhD on subjective privacy in location-based systems from the Quality and Usability Lab at TU Berlin, Germany. She obtained her M.Sc. degree in Signal Processing and Communications Engineering from Tampere University of Technology, Finland, in 2010, focusing on subjective quality and the human perception of stereoscopic videos. Her research focuses on usable privacy the intersection of human users and technology assessing the challenges posed by collection, processing, and distribution of personal information. Her work considers in particular the context of sensor data. She conducts empirical research in which she assesses the effect of various factors such as context on privacy perception and on privacy-related behaviour.
