Trajectory mining, representation and privacy protection [PDF]
Proceedings of the 2nd ACM SIGSPATIAL PhD Workshop, 2015 The maturing of mobile devices and systems provides an unprecedented opportunity to collect a large amount of real world human motion data at all scales. The rich knowledge contained in these data sets is valuable. In this analysis, we first study information dissemination through the physical contacts learnt from the data sets.
