Abstract:
Portable Global Navigation Satellite System (GNSS) -enabled devices enable gathering comprehensive personal trajectory data about the movement of citizens. Such data would be extremely useful for example improving the cyclability of cities. On the other hand, the data is personal and can reveal surprisingly large amount of personal information. To develop robust privacy-aware and utility-preserving methods to obfuscate personal trajectory data, we are faced with the problem that no comprehensive data sets exist that is needed to conduct such studies. Therefore, we are designing an open trajectory repository where citizens can donate their data for science. The main challenges are 1) how to motivate citizens to contribute and 2) how can we share the trajectory data back to participants and to society while respecting the participants’ privacy.
