Abstract: 
The amount of movement data that people record using their
mobile phones via different tracking apps is vast. In a typical case the data
can be viewed within the app but using the data by the third-party for other
purposes is cumbersome, or practically impossible. One way to improve the
situation is to establish an open trajectory data repository, where the users
could save their movement tracks as open data. However, this data is considered
personal data and the users may not be willing to share full trajectories
as they might reveal for example their home locations. Thus, the trajectory
data must be processed to minimize the amount of information that
can be used to identify person while keeping the utility of the data as high
as possible. We launched a survey of peoples’ opinions about sharing their
movement data and what kind of privacy guarantees they would expect.
Based on the preliminary results, a large part of the potential users appears
to be interested in sharing their tracking data, when adequate privacypreserving
pre-processing is performed.
