A trajectory data publishing algorithm satisfying local suppression
International Journal of Distributed Sensor Networks, 2021 Suppressing the trajectory data to be released can effectively reduce the risk of user privacy leakage. However, the global suppression of the data set to meet the traditional privacy model method reduces the availability of trajectory data.

Privacy through uncertainty in location-based services [PDF]
, 2013 Location-Based Services (LBS) are becoming more prevalent. While there are many benefits, there are also real privacy risks. People are unwilling to give up the benefits - but can we reduce privacy risks without giving up on LBS entirely?

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.
