Blind Evaluation of Nearest Neighbor Queries Using Space Transformation to Preserve Location Privacy
14 years 3 months ago
In this paper we propose a fundamental approach to perform the class of Nearest Neighbor (NN) queries, the core class of queries used in many of the location-based services, withou...

We present a homomorphous mapping that converts problems with linear equality constraints into fully unconstrained and lower-dimensional problems for optimization with PSO. This ap...
