Chi-Yin Chow, Mohamed F. Mokbel, Jie Bao, Xuan Liu
2010 Geoinformatica  
In this paper, we propose a new location anonymization algorithm that is designed specifically for the road network environment.  ...  Applying these techniques directly to the road network environment would lead to privacy leakage and inefficient query processing.  ...  Conclusion This paper proposed a query-aware location anonymization algorithm for road network environments.  ...
