Query-aware location anonymization for road networks
2010
Geoinformatica
Preserved Fulltext
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. ...

While the location anonymizer is implemented as a stand alone application, the privacy-aware query processor is embedded into PLACE; a research prototype for location-based database servers. ...
Casper consists of two main components; the location anonymizer that blurs the users' exact location into cloaked spatial regions and the privacy-aware query processor that is responsible on providing ...
Figure 2 gives the GUI screen shot for the adaptive location anonymizer. The GUI mainly shows the current exact locations of all participating mobile users over the road network. ...
