Privacy preserving approach based on temporal and spatial constraints
Lou Wen-xiao · Computer Engineering and Applications Journal · 2008
In the research of PPDM,as two important basic characteristics of privacy information,the temporal and spatiality have been often ignored.In this paper,we combine data security level with temporal and spatial characteristics,and then preserve the data privacy using hierarchy generalized.Further more,a privacy preserving data mining method is proposed based on temporal and spatial constraints.Finally,we analyze and evaluate the method performance,which include information loss and execute time and algorithm effectiveness.
